Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

How To Reduce Word Count In Your Dissertation, Thesis Or Academics Assignments

(without losing those precious marks).

If you follow some of the advice on this blog, chances are one of your biggest challenges is keeping your academic writing projects within the specified word count limits. It’s a good problem to have (at least compared to having not enough to say), and in this post, I’ll discuss 4 steps to reduce word count without risking losing marks.

First things first – write to think.

Before I get started, it’s worth making an important point regarding writing in general. There are essentially two ways to think about the process of writing :

• Writing as the outcome of thinking – in other words, you think deeply first, construct your argument, and then simply transfer it to paper by way of writing. You do little revising.
• Writing as a form of thinking – in other words, writing helps you flesh out your thinking and develop your arguments. Writing is an iterative process, wherein you might revise numerous times and even rewrite altogether, but this all contributes to a better quality of thinking.

Which side of the fence do you sit on? I’m an avid advocate of the latter perspective and approach – and I’m not alone. Numerous books and journal articles have covered the topic of “writing as thinking”. If the idea interests you, have a look at Henning’s “Finding your way in academic writing.”

In short, putting pen to paper as early as possible (i.e. before you feel “ready”) and then revising as your thoughts develop (as a result of writing) is an excellent way to improve the overall quality of your arguments and academic work. To do this, you cannot constantly fret over word count (at least not while you’re writing). Instead, you need to let the words flow onto paper, and then sort the wheat from the chaff at a later stage. Sure, you need some constraints, but forcing yourself to apply X model within 350 words is going to stifle your flow and limit your depth. Rather let your thoughts flow onto paper, and then trim them down once your thinking is fully fleshed out.

What does this have to do with reducing your word count? It means that word count reduction (particularly, the techniques I’ll cover below) is something you do once you’ve wrapped up your writing, not while you write . Accordingly, all the steps I’ll propose here are to be applied after the fact.

Right, let’s get into it. Follow these 4 steps (in this order) to strategically reduce your word count without losing the “meat” of your assignment/dissertation.

Step 1: Audit for purely descriptive content.

Broadly speaking, content can fall into one of two categories – descriptive or analytical.  Simply put, descriptive content eludes to the “what”, whereas analytical content describes the impact and consequence of the event/factor/situation – in other words, the “so what”. The table below highlights some of the differences between the two:

Ideally, you should try to keep your discussion analytical, rather than descriptive ( read more about this here ). There’s always be a need for some descriptive content, but ideally, this should be limited to only that content which forms the foundation for analytical content. Therefore, the first step of word count reduction is to audit for descriptive content which does not lead to analytical content . In other words, content which is purely descriptive, and is not required to get to the “so what?” content.

Read through your dissertation/thesis/assignment and trim out all content that doesn’t make the analytical cut , or doesn’t form a foundation for analysis. This is your first target – be aggressive with your trimming. Descriptive writing is pure fat and will not earn you marks – kill it!

Step 2: Audit for content which does not contribute towards answering your research question(s).

One of the reasons that it’s so important to set unambiguous research questions in your introduction is that this practice allows you to ringfence the focus of your work. In other words, it helps you to narrow the discussion to only that which is most relevant.

That said, as you write, you will invariably produce a fair deal of content that does not contribute towards your research questions . You’ll naturally digress into an interesting but irrelevant discussion about A, B and C – this might be very intellectually satisfying, but it doesn’t contribute to answering your research question. Therefore, this sort of content is your next target. Re-read your document from start to finish through the lens of your research questions or objectives. That which does not in some way contribute to answering the research question(s) or achieving the objective(s) must go .

Step 3: Audit for overly-detailed section summaries.

A good piece of academic writing should always feature summary paragraphs that link the end of one section/chapter to the beginning of the next. They should do this by summarising the key points of the former to the direction and purpose of the latter. For example:

“In this section, the analysis revealed that the key contributors to the issue included A, B and C. Accordingly, these factors will be analysed in the next chapter.”

By stating this link very clearly, you help the reader (marker) to understand your argument (which is, after all, completely new to them), which in turn helps you earn marks. Therefore, these summary sections are important. However, they can become wordy and repetitive, and you should, therefore, audit them.

Make sure that they are summarising only the absolute highlights of your argument and providing a clear, well-justified link to the next section. Don’t restate your entire chapter. The example above is what you should aim for, namely:

• Key observations/insights/highlights – followed by
• Logical link to next section

If you are extremely over word count, you may even consider removing these sections altogether. After all, it is better to remove summary content than core content. This should, however, be an absolute last resort as doing so can seriously reduce the overall flow of your document and blur the “golden thread” of your argument(s).

Step 4: Audit for wordy, bloated discussion.

This is the easiest of the four steps, and typically what most students look for when trying to reduce word count – but it usually has a comparatively minor impact. Therefore, I’m positioning it as the last step.

Naturally, your dissertation, thesis or assignment document will contain sections which are just plain wordy. This is a result of “writing as thinking” (whether you agree with the approach or not!). Therefore, the last step is to audit for sentences and paragraphs which are just plain wordy and rewrite them more concisely.

Some common trimming opportunities:

• Adjectives and adverbs – although these are sometimes necessary when developing your arguments, they are often just bloat contributors. Additionally, they can create an emotive, subjective tone, which is typically not encouraged in academic writing (where objectivity is essential).
• The word “that” – oftentimes, a sentence can communicate the same point without the inclusion of the word “that”. Use Word’s find function (Ctrl+F) to search for “that” and check where it can be omitted.
• Spaces around mathematical operators – if you’re copying numbers from Excel, chances are there are spaces between mathematical operators which can be removed. For example, p < 0.05 (3 words) can be reduced to p<0.05 (1 word).
• Abbreviate/acronymise repetitive phrases/names – if you’re repeatedly referring to a person(s) or organisation(s) that have multi-word names, create acronyms for them and replace all instances with the acronymised version. For example, “Blue Basket Enterprises” (3 words) can be replaced with “BBE” (1 word). Make sure you introduce the acronym early in the document and consider presenting a list of abbreviations. A word of warning – don’t overuse this tactic, as too many acronyms can make it difficult for the reader to understand what’s going on!

Wrapping up.

There you have it – four steps to reduce your word count without losing your core arguments. To recap, you need to:

• Audit for descriptive (rather than analytical) content.
• Audit for content which doesn’t link to the research question(s)/aim(s).
• Audit for overly detailed section summaries.
• Audit for general wordiness and bloat.

Tip 1: Break it into such small, discrete goals that you almost feel silly writing them down individually.

This is by far the most important skill on this list. I only started developing this skill while writing my thesis but have since honed it while working in industrial R&D.   Subscribe to our newsletter at the bottom of this page   for the next blog post “Why I left academia in search of self-development”.

The value of this skill cannot be understated and luckily can be easily learned by anyone. Here’s how I make it work: Set aside 15 minutes for planning out your next 10-20 hours of work on a project. Create a large to-do list for each project (there are a lot of great Excel templates online). You can list some big milestones further out but keep the tiny details within range of tasks you could finish in the next few days. Every morning, review your tasks, add new discrete tasks that are now within range. Add a number (1-10) to every task to denote the order you’re going to work through them for this specific day. Stick to the list and avoid jumping to topics off-list that pop up. If something important   and   urgent pops up, add it to your list and give it a number.

Some examples for your shortlist if you were writing a thesis:

• Send email to professor about feedback from Chapter 4
• Re-format figure captions from Chapter 4
• Write two paragraphs about results from experiments on October 4 th -12 th
• Create summary plot for above experiments
• Import and reformat data from experiments October 19 th -27 th
• Write rough outline for rest of Chapter 5
• Send outline of Chapter 5 to professor
• Review feedback from professor on Chapter 4
• Make list of changes in Chapter 4 based on professor’s feedback this morning

Are you the type of person that writes “Make List” on your to-do list just so you have something to cross off? Do you write down tasks you just finished just to cross them off?

If you are, you have a head start on this method! Creating and working through a list in this much discretized detail has a lot of secondary effects. You’ll be forced to plan out your work in greater detail (and prioritize better). You’ll be more likely to use small chunks of time effectively to make progress and free up more time for yourself. Most importantly,   you’ll finish your day with a sense of accomplishment and forward momentum because you got things done , instead of the feeling that you moved the needle from 23% to 24% complete after 10 hours of work. As ridiculous as this list may sound, I’ve found it has a profound psychological effect on my motivation and momentum for the rest of the day. The key is to have the discipline to spend those first 15 minutes of your day planning instead of reacting to every thought or email that comes in. Try it out for one week straight and make modifications based on what is working for you.

Tip 2: Write everything that comes to mind, then trim and re-organize later.

If it’s flowing in your mind, get it into the whitespace of your document   somewhere . I’ve found that most technical writing blocks come when a person doesn’t know how exactly to write the next thing or isn’t sure what exactly should come next, even though they have ideas and words in their head for later sections. Your brain can get stuck running in circles testing out different ways to present the information and become paralyzed by the endless possibilities coupled with the lack of a clear path.

How can you put a puzzle together if you don’t know what the pieces look like?

It’s much easier to decide on the best idea flow   after   you’ve put the bulk of each idea onto the paper. When you have all the information in place and pseudo-organized, pick through it with a fine-tooth comb to trim down superfluous sentences and smooth out the transitions between paragraphs. Then, send the section to your adviser and group members for feedback. Continue writing other sections while waiting for their feedback.

Tip 3: Recognize that you don’t have to close every single loose end.

The point of your thesis is to document your discoveries and progress so that a new person can carry the torch forward without starting from scratch. If you found something interesting but can’t explain it, just present the data and state the questions still to be answered. Include your ideas about what could be done next to get closer to the answers. If you’ve spent more than three hours banging your head against the table staring at one plot, it’s time to move on to the next section. You’ll be surprised how working on other parts can stimulate ideas that can help close the difficult section off later.

Tip 4: Set up your formatting correctly immediately when starting.

Hopefully you’re proficient in LaTeX. If not (I wasn’t), learn how to properly assign section and sub-section headings in Word and to keep consistent formatting between them. This will be critical for auto-updating your table of contents. It will also help you collapse sections and jump around in your 200+ page document from the sidebar “Navigation Pane”. Create actual captions for your figures and tables using the built-in functionality and link references in the text to those captions. Now, when you add a new image earlier in the document, the figure and all its references will be updated automatically. Make sure to also set up your citation editor right away using the recommended format and make sure it can auto-generate the reference list. You may have gotten away with manually formatting these for short journal article submissions, but you will have untold headaches clicking through the text and re-numbering each reference if you don’t do this from the start. Check with your Graduate Studies department to see if they have a pre-formatted document you can use.

Tip 5: Remember that this is a struggle for   everyone .

If you find yourself getting lost in self-deprecation, re-frame your thinking. Instead of “Why can’t I focus on this?” ask yourself “What factors are causing me to lose focus and how can I limit these or mitigate their effects?” Instead of asking “Why can’t I make sense of this data?”, re-frame it as “How can I present this data factually while pointing out the unknowns?”

Tip 6: Put your phone on airplane mode and out of arms’ reach.

You already know that your phone is the #1 distraction you have. Make the distraction less of a willpower issue and more of a practicality issue by putting your phone on airplane mode and putting it somewhere on the other side of the room, in a box, in another room, etc. The further away, the better. Now you’ll have to weigh the hassle of getting up and retrieving it to quickly check it for notifications.

Tip 7: Use an auto-responder on your email or put it in Do Not Disturb mode.

Once your phone is hidden, it’s time to take care of distractions on your computer. Both Gmail and Outlook have functions to turn off notifications or stop retrieving messages altogether for set periods of time. For instance, you could set your send/receive interval to once every 4 hours. Another trick is to turn on your auto-responder to say something along the lines of “Thanks for your message. In order to focus on my writing, I’m currently only checking email at noon and 6pm. I will get back to you as soon as possible.” Others will pick up on this and email you less often and only about real issues.

Tip 8: Set a visible timer for focused work periods.

I found it much easier to sustain a 45-minute focused session if I knew I had a planned break coming up soon. There are several apps available for setting timers and some that can also mute your notifications while running. If you schedule your breaks (and actually give yourself a break when the timer runs out), you’ll be less likely to want a break at the first sign of frustration.

Tip 9: Build in a short 5-10 minute exercise routine for your breaks.

After a few good hours of focus my biggest hurdle was feeling anxious or restless. Some nights I would decide it was a “workout” night and every 30 minutes or so, I would get on the floor and do a few minutes pushups, crunches, bicycle kicks, leg lifts or planks. After a few minutes of this I’d be tired enough that I would   want   to sit back down and settle in. The big advantage was getting my blood flowing, which can stimulate your brain and give a small energy boost.

Tip 10: Work in an environment around other people who are focused (leverage social pressure).

Do you feel like exercising at high intensity more in an empty gym or one where there are dozens of others giving it their all? For me, it’s the latter. There’s a subconscious social pressure I feel to not stick out as slacking. I found the same effect in the library or coffee shop.

For some ridiculous reason, I felt like people behind me would judge me if I had Facebook up on my screen or was playing a game on my phone.

Even if that judgement was an illusion, I harnessed it to stay on-task. I found this especially helpful after 11pm or so to know that there were others doing the same thing. If all your friends are going out to the bar, do you get FOMO (fear of missing out) more at a coffee shop around others who are studying or staying home in the dark by yourself?

Tip 11: Change scenery regularly until you find your ideal spots.

My favorite part about thesis writing is that   I could work from anywhere . This is a novelty you may never have again in your life, depending on your field. Take advantage of this and find those magical hangouts where you can find your flow and blaze through your work.

In three months of writing, I visited at least eight different coffee shops plus every library on campus.

There were two or three that really worked for me, depending on the time of day. Even after a half-day at one of your favorite spots, it can be reinvigorating to move to another later in the day.

Tip 12: Find your best writing jams and don’t listen to them unless you’re ready to get in the zone.

This is a proven psychological trick. Do you still have a throwback song you associate with middle school or high school sports? Something your team listened to in the locker room to get pumped up? You can manufacture these associations in your brain in a similar way. Find your best playlists, and make sure to pause them while you’re taking breaks or if you find yourself distracted. When the music is on, it’s time to work. Listening to your best playlists while doing other things will dilute the association in your brain, so stay disciplined with this one!

Tip 13: Take a mid-day break with some form of exercise or activity.

The most productive day you can hope for is 10-12 hours of focused effort. If you deprive yourself of breaks early in the day you’re likely to grind to a halt in the evening and lose the equivalent of your would-be break time in procrastination and distraction. Be proactive about scheduling in your down time to elevate your productivity later in the day. For me personally, my best days included several short breaks evenly spread throughout the day plus one mid-day break of ~2 hours. This larger break was usually some combination of exercise, cooking, eating or cleaning. Experiment and find what works best for you!

Tip 14: Set aside 10 minutes in the morning to honestly review what went well and what didn’t work the previous day.

An honest self-assessment will do wonders for improving your methods each day. Approach it like an athlete watching game tape to identify weaknesses. Where did your distractions come from? How did you feel throughout the day?

When was your most productive time and what factors lead to that productivity?

Make changes in your strategy for the upcoming day, and review again the following day to see if it was an improvement.

Tip 15: Add an expected time of completion (ETC) to every item on your to-do list for that day.

This follows Tip #1 to break down projects into tiny discrete and definitely conquerable tasks. Make a reasonable guess of how long each thing should take if it goes smoothly. If you do well and get ahead of schedule, reward yourself with an extra break. If you get behind schedule, you’ll start to feel a sense of urgency that will motivate you to catch up.

The alternative is giving yourself 3 months to complete thousands of micro-tasks, at which point you’ll always feel overwhelmed and unsure of your pace to completion.

Tip 16: Take care of your body.

This is a marathon, not a sprint. Monitor your caffeine intake, your hours of sleep, your periods of exercise and the types of foods you eat. Keep it balanced day-to-day with only the occasional late night push when you're really in the zone. 

Tip 17: Dedicate time to being social!

If you’re writing your thesis you are likely approaching the end of your time at your school. This may be the last few months you have to spend with all of the friends and colleagues you’ve made along your journey. Don’t forget to dedicate a few hours a week to be social and relish in the time you have left to all be together. This is a time of your life you’ll remember forever, so better mix in some great memories!

Rule of Three: advice on writing a PhD thesis

PhD students sometimes get the same bad advice on writing their thesis. I call this advice the Rule of Three . Typically, they get told that their thesis:

• Will take 3 months to write
• Should have 3 results chapters
• Should be 300 pages

These bits of advice have one thing in common: they are all wrong.

• If you have been organised (see below), it should not take 3 months to write a PhD thesis. It certainly shouldn’t involve leaving the lab 3 months before your hand-in date to write up.
• Theses can have one results chapter or they can have more. How many chapters depends on your project, and your results. Trying to make three results chapters out of one chapter ends up in a weak or overlong thesis.
• A thesis is like a piece of string and it will be as long as it needs to be. Aim for brevity and not producing a magnus opus (see below).

Disclaimer: what follows is some different advice. As with all “advice”, your mileage will vary. It is written for the people in my lab but likely applies to UK PhD students doing biomedical research.

Rule 1: aim for a thesis that is good enough

Who will read your thesis? Two people. Your examiners. OK, some parts – such as the Methods section – will be useful to future lab members (although with electronic lab notebooks this function is becoming redundant). Maybe your thesis will be downloaded by someone from the repository, but essentially, it will only be read by your examiners.

How long does an examiner spend reading your thesis? A few hours. One day maximum. They simply have no more time. Do you really want to spend three months of your life writing something that will be read for just a few hours by two people?

It’s for these reasons that spending too much effort writing a perfect thesis is a waste of time. It just needs to be good enough.

As well as being just good enough, it only needs to be long enough . A big mistake students make is to produce a really long thesis because they think that that is what theses should be (rule of 3). What happens is the examiner will receive the thesis, look at how many pages there are, subtract the bibliography, and their heart will sink if it is too long.

You might now be wondering: is writing a thesis a waste of time?

No, because you have to do it to get your PhD.

No, because you learn important writing skills. You also learn how to assemble a large document (it’s often how students learn to use Word properly or up their LaTeX game). It’s good training for writing papers and other technical documents down the line. Employers know this when they hire you.

But that is about it. So you just need to write something that is good enough to pass.

Rule 2: prioritise papers and the thesis will follow

Papers are the priority. They are more useful to you and to your PI. But this advice isn’t motivated by self-interest. If you go into the viva and the work in your thesis is already peer reviewed and published, it’s harder for the examiners to criticise it. At least, they will not approach your thesis with the question: is this work publishable? This is one criteria for passing your PhD, so demonstrating that it is publishable means you are (almost) there.

This was the one bit of advice I received when doing my PhD and it is still true today. OK, it is harder these days to get a first author paper published before you submit your thesis. However a preprint on bioRxiv before you begin writing will help you to prepare your thesis and will still tick the publishable box.

How long should it take to write your thesis?

There is tension here because you are at your most useful in the lab as you near the end of your PhD. One week of labwork now is worth one month (or more) earlier in your PhD. You are most valuable to your lab/PI/science/career at this point and keeping working in the lab will yield more rewards. But it won’t get your thesis written.

The first bit of writing is busywork and can be done around lab work. “Deep writing” and reading does need time away for most students.

If you have only collected data in the lab and not analysed it, if you’ve not presented your work very often, if you are disorganised… yes, it will take you a full three months to write your thesis.

All the folks in my lab are encouraged to get figures ready, analyse as they go and they also give regular talks. It should not take anyone in this position three months away from the lab to write their thesis.

Agreeing a timeline with your PI for when you begin writing is really important. Regular deadlines and a commitment to timely feedback from your supervisor make thesis writing easier. The discussion needs to be based on facts though. Often students want to budget a lot of time to writing, because of the rule of 3 or because they believe they are “bad at writing”. It helps to see some evidence. Writing draft chapters earlier in the PhD – which is a requirement at some universities – can reveal difficulties and weaknesses.

Reality check

If you hear the rule of 3 from everyone and your supervisor is giving you different advice. It might be time for a reality check. Have a look at past theses from the lab. How long were they? How many chapters? Information is good.

You can see that all theses are fewer than 300 pages in length, many substantially so. Four have three chapters and two have two. Although looking closer, two of the theses with three chapters use a results chapter as an expanded methods chapter.

Ultimately, the thesis is your work but you will get input from your supervisor. Regardless of what is written here or how many people tell you about the rule of 3, your supervisor will have their own ideas about how your thesis should be. Agreeing a sensible plan with them is the way to get started productively.

Getting started

This is not a comprehensive guide but in order to write a good enough thesis, you first need a plan.

• Make a figure list. This should be every single figure you can think of. You can cross off ones you don’t need later if they don’t fit or are insignificant.
• Plan the narrative. There is usually more than one way to put together the figures to make a thesis. Be prepared for this to change after you start writing! Sometimes the writing process reveals ways in which the narrative should be rearranged.
• How many results chapters? Start with the idea that you will have one. Does it need dividing? If yes, then what are the titles of the two chapters? If you have difficulty titling them you may need to split to a 3rd.

Now you have a plan. It’s time to get going.

Set some goals – but make them small. Having a goal of “I am going to complete my thesis” is too demoralising. You need to feel like you are making progress constantly to stay motivated. Break it down into smaller chunks. “I will finish this chapter by next Friday”. “I will write the cloning section this morning and then go for a walk”.

Write the materials and methods first . It’s the easiest bit to write because it is all technical writing with little wordcraft required. You can fit it around labwork. In fact, it is easier to write whilst in the lab because you can look up all the stuff you need. Importantly, it gets over the “blank page syndrome”.

Next get your figures together . This should already be done if you have been organised.

Then write the figure legends . You already have the title for each figure from your plan. All you need to do is describe each panel. Again, quite low energy writing required for this task.

Now write the results sections ! This is the same way that we put papers together. The results parts of the thesis are more extended but in principle you will guide the reader though the figures that you’ve made. Remember, you already have the legends written. So you are already partly on your way.

Time to regroup . At this point you can refine your plan for the introduction and check the rest of your plan still makes sense. Now is the time for some deep writing and reading.

The post title comes from “Rule of Three” by The Lemonheads.

How to Write a PhD Thesis: 13 Tips For PhD Thesis Writing 

Completing a successful PhD research thesis is extremely challenging, and how to write a PhD thesis is often a question in students’ minds. Fret not, there are many ways to make the process of PhD thesis writing less bumpy. This article will provide some PhD thesis writing tips to simplify the writing process and help you complete your thesis on time, while keeping your sanity mostly intact. 

Only about 50% of students enrolled in a PhD program ever complete it 1 . They drop out at many different points during the process for many different reasons. Some leave because the course work is too difficult or time consuming. Some leave for personal or financial reasons. One common cause of non-completion, or late completion, is the daunting spectre of PhD thesis writing. 

PhD thesis writing tips: How to overcome the challenge of writing your PhD thesis

First, remember that although writing a PhD thesis is difficult, this can be accomplished. Here are some things to consider that will increase your confidence and make the task of PhD thesis writing a bit less scary. 

• Create an outline before you start writing – The most effective way to keep your work organized is to first create an outline based on the PhD thesis structure required by your university. Using an outline for your PhD paper writing has tremendous benefits. It creates a handy space to keep and organize all the little snippets of information and questions you will have during your preparation. It allows you to effectively plan your work and manage your time and makes the actual writing much easier. A thesis is shaped more than written, and an outline provides it the required PhD thesis structure. 
• Follow all university guides – Be careful to ensure that you are meeting all the requirements of your university. This includes everything from topic selection to structure to writing style. It is extremely frustrating to spend a lot of time and effort on a section only to have to do it over because you didn’t follow the proper guidelines. Read all relevant material from your university over and over until you have it memorized. Then, check it again. 
• Section order – It is usually best not to do your PhD thesis writing in chronological order. For researchers, the easiest parts to write are usually the Method and Results. So, gain some confidence first and write the Introduction and Conclusion last to tie it all together. 
• Work extensively with your supervisor – Don’t forget that in the process of PhD thesis writing, help is right there when you ask for it. Do not hesitate to ask for guidance from your supervisor, advisors, or other committee members when you get stuck. Clear and regular communication with these important resources can save you untold heartache during the PhD research and thesis writing processes. This should not be a solo exercise; they have all been where you are now. 
• Plan carefully, create rough drafts, and refine 2 – This is so important and basic to all academic research that it bears repeating. You will not write the final PhD thesis on your first try. Do not become frustrated, trust the process. 
• Produce quality writing – Make sure your ideas flow easily and are clear and easy to read. This is not a strong skill for most beginning researchers, but it’s a skill that can be learned with a lot of practice. Therefore, edit, edit, and edit some more. If you need it, there are many places to get PhD thesis writing help and assistance. 
• Details matter – Pay attention to the small things, especially with the document formatting. If you start out using the proper format, you will be saving a tremendous amount of time and grief later. 
• Avoid plagiarism – Quote accurately, otherwise paraphrase. There is no excuse for being a lazy writer. Consider using a smart tool or service to check for plagiarism during your PhD thesis editing process to make sure you did not unintentionally copy any material. 
• Rein in the references – Use a database, such as EndNote or Mendeley, to keep them organized and under control; check and double check citations and references with the bibliography to ensure they all match. Don’t forget to use the PhD thesis style required by your university. 
• Keep it simple – Remember, this is only the start of your career, not your ultimate work 3 ; perfectionism can be a disaster. 
• Make consistent progress – Try to write at least a little every day; check quotations and references when writing seems too difficult. 3  
• Keep your reader in mind – As with all writing, your PhD thesis is meant to be read, so be considerate of those who read it; be concise, include all necessary data/information to support your argument but nothing extra. Strive to be understood and avoid unnecessary words. 
• Be persistent and eager – Writing a doctoral thesis becomes easier if you are consistent and dedicated. All other things being equal, your attitude will ultimately determine your success. Have patience and work hard. Create work you will be proud of for a lifetime.

A PhD thesis includes several key components, that are essential for the work to be considered seriously. These may vary depending on the research field and specific requirements of the institution, but generally include: ·         an introduction that presents the research question and context, ·         a literature review that surveys existing knowledge and research, ·         a methodology section describing the research design and methods employed, ·         a presentation of findings or results, ·         a discussion section interpreting the results and their implications, and ·         a conclusion that summarizes the main findings and contributions. Additionally, appendices may contain supplementary materials such as data, charts, or technical details.  

The time required for writing a PhD thesis can vary significantly depending on factors such as the research topic, the individual’s research progress, the specific requirements of the institution, and the researcher’s writing process. On average, it can take several months to a few years to complete a PhD thesis. The research, data collection, and analysis stages can span several years, with the PhD thesis writing phase itself often lasting several months. Here, AI writing assistants like Paperpal, designed for academics, can help you write better. Explore Paperpal and see the difference for yourself!

• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How short or long should be a questionnaire for any research? Researchers dilemma in deciding the appropriate questionnaire length

Hunny sharma.

Department of Community and Family Medicine, All India Institute of Medical Sciences, Raipur, Chhattisgarh, India

A questionnaire plays a pivotal role in various surveys. Within the realm of biomedical research, questionnaires serve a role in epidemiological surveys and mental health surveys and to obtain information about knowledge, attitude, and practice (KAP) on various topics of interest. Questionnaire in border perspective can be of different types like self-administered or professionally administered and according to the mode of delivery paper-based or electronic media–based. Various studies have been conducted to assess the appropriateness of a questionnaire in a particular field and methods to translate and validate them. But very little is known regarding the appropriate length and number of questions in a questionnaire and what role it has in data quality, reliability, and response rates. Hence, this narrative review is to explore the critical issue of appropriate length and number of questions in a questionnaire while questionnaire designing.

Introduction

A questionnaire is an essential tool in epidemiological surveys and mental health surveys and to assess knowledge, attitude, and practice (KAP) on a particular topic of interest. In general, it is a set of predefined questions based on the aim of the research.[ 1 ]

Designing a questionnaire is an art which unfortunately is neglected by most researchers.[ 2 ] A well-designed questionnaire not only saves time for a researcher but helps to obtain relevant information most efficiently, but designing such a questionnaire is complex and time-consuming.[ 3 , 4 ]

The quality of the data obtained by a specific questionnaire depends on the length and number of questions in the questionnaire, the language, and the ease of comprehension of the questions, relevance of the population to which it is administered, and the mode of administration, i.e., the self-administered or paper method or the electronic method [ Figure 1 ].[ 5 , 6 ]

Qualities of a well-designed questionnaire

Response rate is defined as the number of people who responded to a question asked divided by the number of total potential respondents. Response rate which is a crucial factor in determining the quality and generalizability of the outcome of the survey depends indirectly on the length and number of questions in a questionnaire.[ 7 , 8 ]

Several studies have been conducted to assess the appropriateness of the questionnaire in a particular field and methods to translate and validate them. But very little is known regarding the appropriate length and number of questions in a questionnaire and what role it has in data quality and reliability. Hence, this narrative review is to explore the critical issue of appropriate length and number of questions in a questionnaire while questionnaire designing.

What is a questionnaire

Merriam Webster defines the questionnaire as “a set of questions for obtaining statistically useful or personal information from individuals,” whereas Collins defines a questionnaire as “a questionnaire is a written list of questions which are answered by a lot of people to provide information for a report or a survey.” The oxford learners’ dictionaries also give a somewhat similar definition which states that a questionnaire is “a written list of questions that are answered by several people so that information can be collected from the answers.”[ 9 , 10 , 11 ]

Thus, this provides a simpler meaning that a questionnaire in simpler terms is a collection of questions that can be used to collect information from various individuals relevant to the research aims.

Where are questionnaires generally applied?

A questionnaire, in general, can be applied to a wide variety of research which can either be quantitative or qualitative research which completely depends on how and in which a number of open-ended questions are asked.[ 12 ]

Questionnaires are generally applied when a large population has to be assessed or surveyed with relative ease where they play a crucial role in gathering information on the perspectives of individuals in the population.

There is a variety of applications of questionnaire in opinion polls, marketing surveys, and in politics, wherein the context of biomedical research questionnaires are generally used in epidemiological surveys, mental health surveys, surveys on attitudes to a health service or health service utilization, to conduction knowledge, attitude, and practice (KAP) studies on a particular issue or topic of interest.[ 13 , 14 ]

What are the types of questionnaire?

Questionnaires in general are of two types those which are in paper format and those which are in electronic format. The questionnaire can further be of two types i.e., self-administered or professionally administered via interview. The paper format can be administered easily both in self-administered mode or professional administered mode via direct administration when the population is relatively small as it is cumbersome to manage and store the physical questionnaire, paper format can also be administered to a larger population via postal surveys. Electronic questionnaires can be easily administered to a larger population in self-administered mode via Internet-based services like google forms, e-mails, SurveyMonkey, or Survey Junkie, etc. When administering professional-administered questionnaires professional telephonic services must be utilized to interview a larger population in a shorter duration of time.[ 15 , 16 , 17 ]

What it is required to answer individual questions in the questionnaire or the burden imparted on respondents

As mentioned by Bowling, in general, there are at least four intricated steps required in answering a particular question in a questionnaire, these steps are comprehension, recall of information asked by the question from the memory, judgment on the link between the asked question and the recall of information, and at last communication of the information to the questionnaire or evaluator [ Figure 2 ].[ 18 ]

Steps involved for answering a particular question in the questionnaire

In the case of a self-administered questionnaire, there is also a need for critical reading skills which is not required in one-to-one or face-to-face interview which only requires listening and verbal skills to respond to questions in the same language in which they are being asked or interviewed.[ 18 ]

There are many other crucial factors which play an important role in deciding the utility of questionnaire in various research, one such factor is the literacy of the participants which is a major limiting factor in self-administered questionnaires. Whereas, the other factors include the respondent's age, maturity, and level of understanding and cognition, which are some of the other ways related to the comprehension of the questions.[ 19 ]

Do the length of the questionnaire matters?

Length and number of items in the questionnaire play a crucial role in questionnaire-based studies or surveys, it has a direct effect on the time taken by the respondent to complete the questionnaire, cost of the survey or study, response rate, and quality of data obtained.[ 20 ]

As evident from the study conducted by Iglesias and Torgerson in 2000, on the response rate of a mailed questionnaire, an increase in the length of the questionnaire from five pages to seven pages reduces the response rate from women aged 70 years and over but on contrary does not seems to affect the quality of response to questions.[ 21 ]

Another study conducted by Similar Koitsalu et al .[ 22 ] in 2018 reported that they were able to increase overall participation and information gathered through a long questionnaire with the help of prenotification and the use of a reminder without risking a lower response rate.

Whereas Sahlqvist, et al .[ 23 ] in 2011 reported that participants were more likely to respond to the short version of the questionnaire as compared to a long questionnaire.

Testing of ultrashort, short, and long surveys of 13, 25, and 75 questions, respectively by Kost et al .[ 24 ] in 2018, revealed that a shorter survey utilizing a short questionnaire was reliable and produce high response and completion rates than a long survey.

Bolt, on the other hand, in 2014, found a surprising find that reducing the length of a long questionnaire in a physician survey does not mean that it will necessarily improve response rate hence to improve the response rate in nonresponders’ researchers may think to utilize a drastically shortened version of the questionnaire to obtain some relevant information rather than no information.[ 25 ]

But the most interesting find comes from the web-based survey giant “Survey Monkey,” which states that there is a nonlinear relationship between the number of questions in a survey and the time spent answering each question. Which in other words can be explained as more there are questions in a survey lesser time respondent spend answering each question which is known as “speeding up” or “satisficing” through the questions. It is also observed that as the length of and the number of questions asked increased there is an increase in a nonresponse rate. This in term affects the quantity and reliability of the data gathered.[ 26 ]

What happens when respondents lose interest?

When there is a loss of interest, in the case of a long length questionnaire or extensive interviews, the bored respondents provide unconsidered and unreliable answers, or in other scenarios, it may lead to high nonresponse to questions. Where on one side a high nonresponse rate may lead to difficulty in data analysis or an unacceptable reduction in sample size, whereas on the other side, unconsidered or unreliable answers may defeat the whole purpose of the research [ Figure 3 ].[ 19 ]

Consequences of Loss of interest in research participant

Considerations while using a long questionnaire

While using a long questionnaire, a high nonresponse rate should always be expected hence appropriate measures to address the missing data should be considered such as data trimming or data imputation depending on the amount of data missing.[ 27 , 28 ]

While the loss of interest can be administering counteracted by dividing the questionnaire into sections and administering each section separating to avoid respondents’ fatigue or boredom.[ 19 ]

It is always advised that the administration of telephonic interview–based questionnaire should be kept short in general about 30 min to prevent fatigue or inattention which may adversely affect the quality of data. In the case of a very long telephonic interview, questions can be divided into sections, and each section can be administered on separate days or shifts lasting 30 min each. A long questionnaire should preferably be administered through face-to-face interviews.

Designing a questionnaire is an art and requires time and dedication, which in turn leads to the easiest way to measure the relevant information on a desired topic of interest. But many a times, this crucial step in biomedical research is ignored by researchers. With this narrative review, we were able to provide a glimpse of the importance of a good questionnaire. A good questionnaire can be of 25 to 30 questions and should be able to be administered within 30 min to keep the interest and attention of the participants intact. It is observed that as the number of questions increases there is a tendency of the participants speeding up or satisficing through the questions, which severely affect the quality, reliability, and response rates. In case a long questionnaire is essential, it should be divided into sections of 25 to 30 questions each to be delivered at a different time or day. In the case of a long questionnaire i.e., more than 30 questions, a larger amount of missing data or nonresponse rates must be anticipated and provisions should be made to address them. At last, it is always advised that shortening a relatively lengthy questionnaire significantly increases the response.

RIT graduate pursues Ph.D. across time zones

Nastaran Nagshineh, center, defended her Ph.D. thesis at RIT in April. Faculty from RIT’s Rochester and Dubai campuses served on her thesis committee and include, from left to right, Kathleen Lamkin-Kennard, Steven Weinstein, Nathaniel Barlow, and David Kofke (a professor at the University at Buffalo). Mohamed Samaha participated remotely and appears on the video screen behind the group and alongside Nagshineh’s picture.

Nastaran Nagshineh is one of the first Ph.D. candidates to bridge RIT’s Rochester and Dubai campuses. Her accomplishment creates a path for future students at the university’s international campuses.

Nagshineh completed her Ph.D. in mathematical modeling while working full time as a mathematics lecturer at RIT Dubai in the United Arab Emirates, teaching as many as five classes a semester. She described her Ph.D. journey as “an exercise in perseverance” due to competing demands and long days. Rochester is eight hours behind Dubai, and the time difference meant many late-night classes and meetings.

“I saw this collaboration as an opportunity, rather than as a challenge, because my primary adviser, Dr. Steven Weinstein (RIT professor of chemical engineering), and my co-adviser, Dr. Mohamed Samaha (RIT Dubai associate professor of mechanical engineering), both have the same area of research interest,” she said. “They both worked toward my success.”

Nagshineh is one of 67 RIT Ph.D. students who defended their thesis this academic year and who will earn their doctorate. RIT awarded 63 Ph.D. degrees in 2023.

In 2020-2021, RIT’s Graduate School met and surpassed the university’s goal of conferring 50 Ph.D. degrees during an academic year. That number will continue to grow as students cycle through the seven new Ph.D. programs that RIT has added since 2017, said Diane Slusarski , dean of RIT’s Graduate School.

Meeting these goals puts RIT on a path toward achieving an “R1,” or research-intensive designation, from the Carnegie Classification of Institutions of Higher Learning. RIT is currently ranked as an R2 institution . Many factors go into changing a university’s status, including research investment and maintaining a three-year average of 70 Ph.D. degrees awarded per year, according to Slusarski.

“We have met the goals of the strategic plan, and now we look forward to contributing to the research innovation in the future,” Slusarski said. “We want to help the new programs thrive and win national research awards.”

RIT’s emphasis on high-level research is seen in Nagshineh’s Ph.D. work. She applies mathematical modeling to the field of fluid dynamics. Her research has been published in top-tier journals and has gained notice, said Weinstein, her thesis adviser.

Weinstein describes Nagshineh’s accomplishments as “a testament to a fantastic work ethic and commitment” and is inspirational to younger students at Rochester and Dubai.

“The collaboration between RIT Dubai/Rochester has continued,” he said. “Another paper was submitted a few weeks ago with Mohamed Samaha and Nate Barlow (RIT associate professor in the School of Mathematics and Statistics) as co-authors, as well as Cade Reinberger, a younger Ph.D. student in my research group.”

Mathematical modeling is one of RIT’s newer Ph.D. degree programs, and Nagshineh is among its earliest graduates. The program has doubled in size since it began accepting students in 2017, Slusarski said. This past fall, the mathematical modeling program had 35 students, with two graduating this year.

Altogether, RIT has 13 Ph.D. degree programs currently enrolling 438 students, with computing and information sciences accounting for the largest with 117 students. RIT’s other Ph.D. programs include astrophysical sciences and technology , biomedical and chemical engineering , business administration , color science , electrical and computer engineering, imaging science , mechanical and industrial engineering , microsystems engineering , and sustainability .

New programs in cognitive science and physics will launch in the fall.

The growth in RIT graduate education—with more than 3,000 master’s and doctoral students—reflects a demographic change in the student population, Slusarski said. “We have a higher percentage of women in the graduate programs than we have for RIT undergraduate programs.”

RIT’s graduate programs enroll 42 percent women, according to Christie Leone , assistant dean for the Graduate School.

Nagshineh, who also holds an MS in electrical engineering from RIT Dubai, welcomes her role as a mentor to other women students on both campuses.

“As a young woman in an Arabic country, the power of women is often underestimated and undervalued, and I hope to serve as a role model to female students, especially those that question their path,” Nagshineh said.

She plans to continue in her career as a professor and a researcher. “I would like to pursue a research program where I can advise my own students and teach them more deeply.”
