• What Is a PhD Thesis?
• Doing a PhD

This page will explain what a PhD thesis is and offer advice on how to write a good thesis, from outlining the typical structure to guiding you through the referencing. A summary of this page is as follows:

• A PhD thesis is a concentrated piece of original research which must be carried out by all PhD students in order to successfully earn their doctoral degree.
• The fundamental purpose of a thesis is to explain the conclusion that has been reached as a result of undertaking the research project.
• The typical PhD thesis structure will contain four chapters of original work sandwiched between a literature review chapter and a concluding chapter.
• There is no universal rule for the length of a thesis, but general guidelines set the word count between 70,000 to 100,000 words .

What Is a Thesis?

A thesis is the main output of a PhD as it explains your workflow in reaching the conclusions you have come to in undertaking the research project. As a result, much of the content of your thesis will be based around your chapters of original work.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available. As such, you can’t rely on other ideas or results to produce your thesis; it needs to be an original piece of text that belongs to you and you alone.

What Should a Thesis Include?

Although each thesis will be unique, they will all follow the same general format. To demonstrate this, we’ve put together an example structure of a PhD thesis and explained what you should include in each section below.

Acknowledgements

This is a personal section which you may or may not choose to include. The vast majority of students include it, giving both gratitude and recognition to their supervisor, university, sponsor/funder and anyone else who has supported them along the way.

1. Introduction

Provide a brief overview of your reason for carrying out your research project and what you hope to achieve by undertaking it. Following this, explain the structure of your thesis to give the reader context for what he or she is about to read.

2. Literature Review

Set the context of your research by explaining the foundation of what is currently known within your field of research, what recent developments have occurred, and where the gaps in knowledge are. You should conclude the literature review by outlining the overarching aims and objectives of the research project.

3. Main Body

This section focuses on explaining all aspects of your original research and so will form the bulk of your thesis. Typically, this section will contain four chapters covering the below:

• your research/data collection methodologies,
• your results,
• a comprehensive analysis of your results,
• a detailed discussion of your findings.

Depending on your project, each of your chapters may independently contain the structure listed above or in some projects, each chapter could be focussed entirely on one aspect (e.g. a standalone results chapter). Ideally, each of these chapters should be formatted such that they could be translated into papers for submission to peer-reviewed journals. Therefore, following your PhD, you should be able to submit papers for peer-review by reusing content you have already produced.

4. Conclusion

The conclusion will be a summary of your key findings with emphasis placed on the new contributions you have made to your field.

When producing your conclusion, it’s imperative that you relate it back to your original research aims, objectives and hypotheses. Make sure you have answered your original question.

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

How Many Words Is a PhD Thesis?

A common question we receive from students is – “how long should my thesis be?“.

Every university has different guidelines on this matter, therefore, consult with your university to get an understanding of their full requirements. Generally speaking, most supervisors will suggest somewhere between 70,000 and 100,000 words . This usually corresponds to somewhere between 250 – 350 pages .

We must stress that this is flexible, and it is important not to focus solely on the length of your thesis, but rather the quality.

How Do I Format My Thesis?

Although the exact formatting requirements will vary depending on the university, the typical formatting policies adopted by most universities are:

What Happens When I Finish My Thesis?

After you have submitted your thesis, you will attend a viva . A viva is an interview-style examination during which you are required to defend your thesis and answer questions on it. The aim of the viva is to convince your examiners that your work is of the level required for a doctoral degree. It is one of the last steps in the PhD process and arguably one of the most daunting!

For more information on the viva process and for tips on how to confidently pass it, please refer to our in-depth PhD Viva Guide .

How Do I Publish My Thesis?

Unfortunately, you can’t publish your thesis in its entirety in a journal. However, universities can make it available for others to read through their library system.

If you want to submit your work in a journal, you will need to develop it into one or more peer-reviewed papers. This will largely involve reformatting, condensing and tailoring it to meet the standards of the journal you are targeting.

How to write a Doctoral Thesis

Prof. HR Ahmad, Department of Biological and Biomedical Sciences, The Aga Khan University, Karachi, Pakistan. E-mail: [email protected]

Note: * Ahmad HR. In: Medical Writing. Eds. SA Jawaid, MH Jafary & SJ Zuberi. PMJA, 1997 Ed II: 133-142.

PATIENT care and teaching are rather well established components of our medical career. However, with the passage of time a third component has started to influence our medical culture, namely research. 1 - 4 How to accept this challenge is a question. 5 Indeed, teaching and research form a dialectic unit, meaning that teaching without a research component is like a soup without salt. It is a well-established fact that the research activity of an institution is directly proportional to the number of qualified and committed PhD candidates. An inspiring infrastructure, laboratory facilities and libraries are pre-requisites for a research culture to grow. 6 - 8 This forms the basis of a generation cycle for an institution, so that research activity and its culture continues to grow from one generation to the next. The main objective of doctoral work in biomedical sciences is to develop a galaxy of scientist physicians and surgeons possessing high degree of humility, selflessness and ethical superiority. Such a programme will add a scholastic dimension to the clinical faculty.

Education in how to write a doctoral thesis or dissertation should be a part of the postgraduate curriculum, parallel to the laboratory work and Journal Club activities during the PhD studies and/or residency levels. 9 , 10 The overall structure of a doctoral thesis is internationally standardized. However, it varies in style and quality, depending upon how original the work is, and how much the author has understood the work. Therefore a thorough discussion with supervisor, colleagues and assistance from other authors through correspondence can be useful sources for consultation.

The choice of a topic for a doctoral thesis is a crucial step. It should be determined by scanning the literature whether the topic is original or similar work has already been done even a hundred years ago. It is the responsibility of both the supervisor and the PhD candidate to sort out this problem by continuous use of internet and a library. 11 The work leading to the PhD degree can originate from research in following spheres: 12

• b) Methodology
• c) Diagnostic
• d) Therapeutic and Management
• e) Epidemiology

The availability of internationally standardized methods, as well as research committed supervisors can enable physicians and surgeons to do PhD work in both basic and clinical health sciences. The importance of research in basic health sciences cannot be overemphasized. It is rather the base of the applied sciences. There are many instances where the elucidation of a mechanism involved in a process awaits the development of an adequate methodology. 13 In such a scenario; a new method is like a new eye. Research activity in the field of (a) and (b) illuminates the research directions for (c) (d) and (e). It is worth noting that sometimes important basic questions can come from (e) and stimulate research activity in the domain of basic health sciences. 14 , 15

INTRODUCTION

A book containing the pearls of a PhD work has standardized divisions and formats, where the number of pages should be weighted in terms of content rather than container. The book includes summary, introduction, materials and methods, results, discussion, conclusions, references and acknowledgements.

Two exercises are mandatory before starting a PhD programme:

• Literature survey using a regular library hours and internet surfing
• Familiarization with the hands-on-experience of methodology involved in the work
• The importance of a continuous literature survey using library, internet and direct correspondence with authors across the globe in the same field cannot be over-emphasized. The main goal of this exercise is to pinpoint the unresolved problem in the literature. An attempt to solve this problem now becomes the topic of the PhD thesis. All the relevant references should be collected, and carefully preserved in the form of a card system arranged alphabetically according to themes and authors. The introduction of the thesis should be styled like a review article with a critical analysis of the work of authors in the literature. The aims of the present PhD work can then also be addressed in the form of questions. The objectives would then deal with how to achieve the aims of the proposed study.

MATERIALS / SUBJECTS AND METHODS

Now comes the most crucial and functional part of the doctoral work, the materials/subjects and methods section. This part can be considered as the motor of the PhD work. The reliability, sensitivity and specificity of the motor must be checked before embarking on a long journey. Controlling the controls is the best guide for a precise and authentic work. Usually materials and methods contain components such as a description of the species involved, their number, age, weight and anthropometric parameters, types of surgical procedures and anesthesia if applied, and a detailed description of methodology. Continuous or point measurements should be thoroughly described. However, a dynamic method should always be preferred to static one.

The experimental protocol should be designed after a small pilot study, which is especially advisable in research on human subjects. A detailed and well-thought experimental protocol forms the basis of conditions under which the results would be obtained. Any deviation from the experimental protocol will affect the outcome, and the interpretation of results. It may be noted that great discoveries are usually accidental and without a protocol, based merely on careful observation! However, for the sake of a publication, a protocol has to be designed after the discovery. After having described the different phases of the experimental protocol with the help of a schematic diagram e.g., showing variables, time period and interventions, the selection of a statistical method should be discussed. Negative results should not be disregarded because they represent the boundary conditions of positive results. Sometimes the negative results are the real results.

It is usual practice that most PhD candidates start writing the methodological components first. This is followed by writing the results. The pre-requisites for writing results are that all figures, tables, schematic diagrams of methods and a working model should be ready. They should be designed in such a way that the information content of each figure should, when projected as a frame be visually clear to audience viewing it from a distance of about fifty feet. It is often observed that the presenters themselves have difficulty in deciphering a frame of the Power-Point being projected in a conference.

The results of a doctoral thesis should be treated like a bride. The flow of writing results becomes easier if all figures and tables are well prepared. This promotes the train of thoughts required to analyze the data in a quantitative fashion. The golden rule of writing results of a thesis is to describe what the figure shows. No explanation is required. One should avoid writing anything which is not there in a figure. Before writing one should observe each diagram for some time and make a list of observations in the form of key words. The more one has understood the information content of a figure; the better will be the fluency of writing. The interruption of the flow in writing most often indicates that an author has not understood the results. Discussion with colleagues or reference to the literature is the only remedy, and it functions sometimes like a caesarean procedure.

Statistical methods are good devices to test the degree of authenticity and precision of results if appropriately applied. The application of statistical technique in human studies poses difficulties because of large standard deviations. Outliers must be discussed, if they are excluded for the sake of statistical significance. Large standard deviations can be minimized by increasing the number of observations. If a regression analysis is not weighted, it gives faulty information. The correlation coefficient value can change from 0.7 to 0.4 if the regression analysis is weighted using Fisher’s test. The dissection of effect from artifact should be analysed in such a way that the signal to noise ratio of a parameter should be considered. A competent statistician should always be consulted in order to avoid the danger of distortion of results.

The legend of a figure should be well written. It contains a title, a brief description of variables and interventions, the main effect and a concluding remark conveying the original message. The writing of PhD work is further eased by a well maintained collection of data in the form of log book, original recordings, analyzed references with summaries and compiling the virgin data of the study on master plan sheet to understand the original signals before submitting to the procedures of statistics. The original data belong to the laboratory of an institution where it came into being and should be preserved for 5-7 years in the archive for the sake of brevity.

This is the liveliest part of a thesis. Its main goal is to defend the work by staging a constructive debate with the literature. The golden rule of this written debate should be that a rigid explanation looks backward and a design looks forward. The object is to derive a model out of a jig-saw puzzle of information. It should be designed in such a way that the results of the present study and those of authors from the literature can be better discussed and interpreted. Agreement and disagreement can be better resolved if one considers under what experimental conditions the results were obtained by the various authors. It means that the boundary conditions for each result should be carefully analyzed and compared.

The discussion can be divided into the following parts:

• criticism of material/subjects and methods
• a list of important observations of the present study
• interpretation and comparison of results of other authors using a literature table
• design of a model
• claim of an original research work
• The criticism of the methodological procedure enables a candidate to demonstrate how precisely the research work has been carried out. The interpretation of results depends critically on the strict experimental protocol and methods. For example, an epidemiological work is a study of a population. However, if the population sampling is done regularly at a specific location; the question arises as to how a result derived from a localized place can be applied to the whole population.
• After having discussed at length the strong and weak points of material/subjects and methods, one should list in a telegraphic design the most important observations of the present study. This may form a good agenda to initiate interpretation, argument, reasoning and comparison with results of other authors. The outcome of this constructive debate should permit the design of a working model in the form of a block diagram. All statements should be very carefully referenced. The ratio of agreement and disagreement should indicate the ability of the author to reconcile conflicting data in an objective and quantitative way. Attempts should be made to design a solution out of the given quantum of information. It is also well known that most of the processes of human physiology can only be understood if their time course is known. The dynamic aspect of interpretation of results is therefore more powerful and superior to the static one. 16 Therefore a continuous record of variables should be preferred and sought to reveal the secrets hidden in the kinetics.
• Finally, the discussion should conclude how far the study was successful in answering the questions being posed at the end of the introduction part. Usually a doctoral thesis raises more questions than it answers. In this way research does not come to a standstill and does become a life time engagement for a committed scientist. Also it is important to note that all scientific theses should be quantifiable and falsifiable, otherwise they lose the spirit and fragrance of a scientific research.
• The author’s claim of original work is finally decided by the critical review of his research work by the literature and the number of times being cited. It can be easily read by a high rate of a citation index of a publication and invitation. When a methodological research clicks, one becomes a star overnight.

Type-II: CUMULATIVE DOCTORAL THESES

Another way of writing a doctoral work is a cumulative type of thesis. 11 It consists of a few original publications in refereed journals of repute. It is supplemented by a concise summary about the research work. This type of thesis is usually practiced in Sweden, Germany and other countries. It has the advantage of being doubly refereed by the journals and the faculty of health sciences. Additionally, papers are published during a doctoral work. A declaration has to be given to the faculty of science about the sharing of research work in publications, provided there are co-authors. The weightage should be in favour of the PhD candidate, so that the thesis can ethically be better defended before the team of august research faculty.

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.

PhD Thesis Guide

This phd thesis guide will guide you step-by-step through the thesis process, from your initial letter of intent to submission of the final document..

All associated forms are conveniently consolidated in the section at the end.

Deadlines & Requirements

Students should register for HST.ThG during any term in which they are conducting research towards their thesis. Regardless of year in program students registered for HST.ThG in a regular term (fall or spring) must meet with their research advisor and complete the  Semi-Annual PhD Student Progress Review Form to receive credit.

Years 1 - 2

• Students participating in lab rotations during year 1, may use the optional MEMP Rotation Registration Form , to formalize the arrangement and can earn academic credit by enrolling in HST.599. 
• A first letter of intent ( LOI-1 ) proposing a general area of thesis research and research advisor is required by April 30th of the second year of registration.
• A second letter of intent ( LOI-2 ) proposing a thesis committee membership and providing a more detailed description of the thesis research is required by April 30th of the third year of registration for approval by the HST-IMES Committee on Academic Programs (HICAP).

Year 4 

• Beginning in year 4, (or after the LOI-2 is approved) the student must meet with their thesis committee at least once per semester.
• Students must formally defend their proposal before the approved thesis committee, and submit their committee approved proposal to HICAP  by April 30 of the forth year of registration.
• Meetings with the thesis committee must be held at least once per semester. 

HST has developed these policies to help keep students on track as they progress through their PhD program. Experience shows that students make more rapid progress towards graduation when they interact regularly with a faculty committee and complete their thesis proposal by the deadline.

Getting Started

Check out these resources  for finding a research lab.

The Thesis Committee: Roles and Responsibilities

Students perform doctoral thesis work under the guidance of a thesis committee consisting of at least three faculty members from Harvard and MIT (including a chair and a research advisor) who will help guide the research. Students are encouraged to form their thesis committee early in the course of the research and in any case by the end of the third year of registration. The HST IMES Committee on Academic Programs (HICAP) approves the composition of the thesis committee via the letter of intent and the thesis proposal (described below). 

Research Advisor

The research advisor is responsible for overseeing the student's thesis project. The research advisor is expected to:

• oversee the research and mentor the student;
• provide a supportive research environment, facilities, and financial support;
• discuss expectations, progress, and milestones with the student and complete the  Semi-Annual PhD Student Progress Review Form each semester;
• assist the student to prepare for the oral qualifying exam;
• guide the student in selecting the other members of the thesis committee;
• help the student prepare for, and attend, meetings of the full thesis committee, to be held at least once per semester;
• help the student prepare for, and attend, the thesis defense;
• evaluate the final thesis document.

The research advisor is chosen by the student and must be a faculty member of MIT* or Harvard University and needs no further approval.  HICAP may approve other individuals as research advisor on a student-by-student basis. Students are advised to request approval of non-faculty research advisors as soon as possible.  In order to avoid conflicts of interest, the research advisor may not also be the student's academic advisor. In the event that an academic advisor becomes the research advisor, a new academic advisor will be assigned.

The student and their research advisor must complete the Semi-Annual PhD Student Progress Review during each regular term in order to receive academic credit for research.  Download Semi Annual Review Form

*MIT Senior Research Staff are considered equivalent to faculty members for the purposes of research advising. No additional approval is required.

Thesis Committee Chair

Each HST PhD thesis committee is headed administratively by a chair, chosen by the student in consultation with the research advisor. The thesis committee chair is expected to:

• provide advice and guidance concerning the thesis research; 
• oversee meetings of the full thesis committee, to be held at least once per semester;
• preside at the thesis defense; 
• review and evaluate the final thesis document.

The thesis committee chair must be well acquainted with the academic policies and procedures of the institution granting the student's degree and be familiar with the student's area of research. The research advisor may not simultaneously serve as thesis committee chair.

For HST PhD students earning degrees through MIT, the thesis committee chair must be an MIT faculty member. A select group of HST program faculty without primary appointments at MIT have been pre-approved by HICAP to chair PhD theses awarded by HST at MIT in cases where the MIT research advisor is an MIT faculty member.**

HST PhD students earning their degree through Harvard follow thesis committee requirements set by the unit granting their degree - either the Biophysics Program or the School of Engineering and Applied Sciences (SEAS).

** List of non-MIT HST faculty approved to chair MIT thesis proposals when the research advisor is an MIT faculty member.

In addition to the research advisor and the thesis committee chair, the thesis committee must include one or more readers. Readers are expected to:

• attend meetings of the full thesis committee, to be held at least once per semester;
• attend the thesis defense; 

Faculty members with relevant expertise from outside of Harvard/MIT may serve as readers, but they may only be counted toward the required three if approved by HICAP.

The members of the thesis committee should have complementary expertise that collectively covers the areas needed to advise a student's thesis research. The committee should also be diverse, so that members are able to offer different perspectives on the student's research. When forming a thesis committee, it is helpful to consider the following questions: 

• Do the individuals on the committee collectively have the appropriate expertise for the project?
• Does the committee include at least one individual who can offer different perspectives on the student's research?  The committee should include at least one person who is not closely affiliated with the student's primary lab. Frequent collaborators are acceptable in this capacity if their work exhibits intellectual independence from the research advisor.
• If the research has a near-term clinical application, does the committee include someone who can add a translational or clinical perspective?  
• Does the committee conform to HST policies in terms of number, academic appointments, and affiliations of the committee members, research advisor, and thesis committee chair as described elsewhere on this page?

[Friendly advice: Although there is no maximum committee size, three or four is considered optimal. Committees of five members are possible, but more than five is unwieldy.]

Thesis Committee Meetings

Students must meet with their thesis committee at least once each semester beginning in the fourth year of registration. It is the student's responsibility to schedule these meetings; students who encounter difficulties in arranging regular committee meetings can contact Julie Greenberg at jgreenbe [at] mit.edu (jgreenbe[at]mit[dot]edu) .

The format of the thesis committee meeting is at the discretion of the thesis committee chair. In some cases, the following sequence may be helpful:

• The thesis committee chair, research advisor, and readers meet briefly without the student in the room;
• The thesis committee chair and readers meet briefly with the student, without the advisor in the room;
• The student presents their research progress, answers questions, and seeks guidance from the members of the thesis committee;

Please note that thesis committee meetings provide an important opportunity for students to present their research and respond to questions. Therefore, it is in the student's best interest for the research advisor to refrain from defending the research in this setting.

Letters of Intent

Students must submit two letters of intent ( LOI-1 and LOI-2 ) with applicable signatures. 

In LOI-1, students identify a research advisor and a general area of thesis research, described in 100 words or less. It should include the area of expertise of the research advisor and indicate whether IRB approval (Institutional Review Board; for research involving human subjects) and/or IACUC approval (Institutional Animal Care and Use Committee; for research involving vertebrate animals) will be required and, if so, from which institutions. LOI-1 is due by April 30 of the second year of registration and and should be submitted to HICAP, c/o Traci Anderson in E25-518. 

In LOI-2, students provide a description of the thesis research, describing the Background and Significance of the research and making a preliminary statement of Specific Aims (up to 400 words total). In LOI-2, a student also proposes the membership of their thesis committee. In addition to the research advisor, the proposed thesis committee must include a chair and one or more readers, all selected to meet the specified criteria . LOI-2 is due by April 30th of the third year of registration and should be submitted to HICAP, c/o Traci Anderson in E25-518.

LOI-2 is reviewed by the HST-IMES Committee on Academic Programs (HICAP) to determine if the proposed committee meets the specified criteria and if the committee members collectively have the complementary expertise needed to advise the student in executing the proposed research. If HICAP requests any changes to the proposed committee, the student must submit a revised LOI-2 for HICAP review by September 30th of the fourth year of registration. HICAP must approve LOI-2 before the student can proceed to presenting and submitting their thesis proposal. Any changes to the thesis committee membership following HICAP approval of LOI-2 and prior to defense of the thesis proposal must be reported by submitting a revised LOI-2 form to HICAP, c/o tanderso [at] mit.edu (Traci Anderson) . After final HICAP approval of LOI-2, which confirms the thesis committee membership, the student may proceed to present their thesis proposal to the approved thesis committee, as described in the next section.

Students are strongly encouraged to identify tentative thesis committee members and begin meeting with them as early as possible to inform the direction of their research. Following submission of LOI-2, students are required to hold at least one thesis committee meeting per semester. Students must document these meetings via the Semi- Annual PhD Student Progress Review form in order to receive a grade reflecting satisfactory progress in HST.ThG.

Thesis Proposal and Proposal Presentation

For MEMP students receiving their degrees through MIT, successful completion of the Oral Qualifying Exam is a prerequisite for the thesis proposal presentation. For MEMP students receiving their degrees through Harvard, the oral qualifying exam satisfies the proposal presentation requirement.

Proposal Document

Each student must present a thesis proposal to a thesis committee that has been approved by HICAP via the LOI-2 and then submit a full proposal package to HICAP by April 30th of the fourth year of registration. The only exception is for students who substantially change their research focus after the fall term of their third year; in those cases the thesis proposal must be submitted within three semesters of joining a new lab. Students registering for thesis research (HST.THG) who have not met this deadline may be administratively assigned a grade of "U" (unsatisfactory) and receive an academic warning.

The written proposal should be no longer than 4500 words, excluding references. This is intended to help students develop their proposal-writing skills by gaining experience composing a practical proposal; the length is comparable to that required for proposals to the NIH R03 Small Research Grant Program. The proposal should clearly define the research problem, describe the proposed research plan, and defend the significance of the work. Preliminary results are not required. If the proposal consists of multiple aims, with the accomplishment of later aims based on the success of earlier ones, then the proposal should describe a contingency plan in case the early results are not as expected.

Proposal Presentation

The student must formally defend the thesis proposal before the full thesis committee that has been approved by HICAP.

Students should schedule the meeting and reserve a conference room and any audio visual equipment they may require for their presentation. To book a conference room in E25, please contact Joseph Stein ( jrstein [at] mit.edu (jrstein[at]mit[dot]edu) ).

Following the proposal presentation, students should make any requested modifications to the proposal for the committee members to review. Once the committee approves the proposal, the student should obtain the signatures of the committee members on the forms described below as part of the proposal submission package.

[Friendly advice: As a professional courtesy, be sure your committee members have a complete version of your thesis proposal at least one week in advance of the proposal presentation.]

Submission of Proposal Package

When the thesis committee has approved the proposal, the student submits the proposal package to HICAP, c/o Traci Anderson in E25-518, for final approval. HICAP may reject a thesis proposal if it has been defended before a committee that was not previously approved via the LOI-2.

The proposal package includes the following: 

• the proposal document
• a brief description of the project background and significance that explains why the work is important;
• the specific aims of the proposal, including a contingency plan if needed; and
• an indication of the methods to be used to accomplish the specific aims.
• signed research advisor agreement form(s);
• signed chair agreement form (which confirms a successful proposal defense);
• signed reader agreement form(s).

Thesis Defense and Final Thesis Document

When the thesis is substantially complete and fully acceptable to the thesis committee, a public thesis defense is scheduled for the student to present his/her work to the thesis committee and other members of the community. The thesis defense is the last formal examination required for receipt of a doctoral degree. To be considered "public", a defense must be announced to the community at least five working days in advance. At the defense, the thesis committee determines if the research presented is sufficient for granting a doctoral degree. Following a satisfactory thesis defense, the student submits the final thesis document, approved by the research advisor, to Traci Anderson via email (see instructions below).

[Friendly advice: Contact jrstein [at] mit.edu (Joseph Stein) at least two weeks before your scheduled date to arrange for advertising via email and posters. A defense can be canceled for insufficient public notice.]

Before the Thesis Defense 

Committee Approves Student to Defend: The thesis committee, working with the student and reviewing thesis drafts, concludes that the doctoral work is complete. The student should discuss the structure of the defense (general guidelines below) with the thesis committee chair and the research advisor. 

Schedule the Defense: The student schedules a defense at a time when all members of the thesis committee will be physical present. Any exceptions must be approved in advance by the IMES/HST Academic Office.

Reserve Room: It is the student's responsibility to reserve a room and any necessary equipment. Please contact imes-reservation [at] mit.edu (subject: E25%20Room%20Reservation) (IMES Reservation) to  reserve rooms E25-140, E25-141, E25-119/121, E25-521. 

Final Draft: A complete draft of the thesis document is due to the thesis committee two weeks prior to the thesis defense to allow time for review.  The thesis should be written as a single cohesive document; it may include content from published papers (see libraries website on " Use of Previously Published Material in a Thesis ") but it may not be a simple compilation of previously published materials.

Publicize the Defense:   The IMES/HST Academic Office invites the community to attend the defense via email and a notice on the HST website. This requires that the student email a thesis abstract and supplemental information to  jrstein [at] mit.edu (Joseph Stein)  two weeks prior to the thesis defense. The following information should be included: Date and time, Location, (Zoom invitation with password, if offering a hybrid option), Thesis Title, Names of committee members, with academic and professional titles and institutional affiliations. The abstract is limited to 250 words for the poster, but students may optionally submit a second, longer abstract for the email announcement.

Thesis Defense Guidelines

Public Defense: The student should prepare a presentation of 45-60 minutes in length, to be followed by a public question and answer period of 15–30 minutes at discretion of the chair.

Committee Discussion:  Immediately following the public thesis presentation, the student meets privately with the thesis committee and any other faculty members present to explore additional questions at the discretion of the faculty. Then the thesis committee meets in executive session and determines whether the thesis defense was satisfactory. The committee may suggest additions or editorial changes to the thesis document at this point.

Chair Confirms Pass: After the defense, the thesis committee chair should inform Traci Anderson of the outcome via email to tanderso [at] mit.edu (tanderso[at]mit[dot]edu) .

Submitting the Final Thesis Document

Please refer to the MIT libraries  thesis formatting guidelines .

Know How to Structure Your PhD Thesis

• 4 minute read
• 33.7K views

Table of Contents

In your academic career, few projects are more important than your PhD thesis. Unfortunately, many university professors and advisors assume that their students know how to structure a PhD. Books have literally been written on the subject, but there’s no need to read a book in order to know about PhD thesis paper format and structure. With that said, however, it’s important to understand that your PhD thesis format requirement may not be the same as another student’s. The bottom line is that how to structure a PhD thesis often depends on your university and department guidelines.

But, let’s take a look at a general PhD thesis format. We’ll look at the main sections, and how to connect them to each other. We’ll also examine different hints and tips for each of the sections. As you read through this toolkit, compare it to published PhD theses in your area of study to see how a real-life example looks.

Main Sections of a PhD Thesis

In almost every PhD thesis or dissertation, there are standard sections. Of course, some of these may differ, depending on your university or department requirements, as well as your topic of study, but this will give you a good idea of the basic components of a PhD thesis format.

• Abstract : The abstract is a brief summary that quickly outlines your research, touches on each of the main sections of your thesis, and clearly outlines your contribution to the field by way of your PhD thesis. Even though the abstract is very short, similar to what you’ve seen in published research articles, its impact shouldn’t be underestimated. The abstract is there to answer the most important question to the reviewer. “Why is this important?”
• Introduction : In this section, you help the reviewer understand your entire dissertation, including what your paper is about, why it’s important to the field, a brief description of your methodology, and how your research and the thesis are laid out. Think of your introduction as an expansion of your abstract.
• Literature Review : Within the literature review, you are making a case for your new research by telling the story of the work that’s already been done. You’ll cover a bit about the history of the topic at hand, and how your study fits into the present and future.
• Theory Framework : Here, you explain assumptions related to your study. Here you’re explaining to the review what theoretical concepts you might have used in your research, how it relates to existing knowledge and ideas.
• Methods : This section of a PhD thesis is typically the most detailed and descriptive, depending of course on your research design. Here you’ll discuss the specific techniques you used to get the information you were looking for, in addition to how those methods are relevant and appropriate, as well as how you specifically used each method described.
• Results : Here you present your empirical findings. This section is sometimes also called the “empiracles” chapter. This section is usually pretty straightforward and technical, and full of details. Don’t shortcut this chapter.
• Discussion : This can be a tricky chapter, because it’s where you want to show the reviewer that you know what you’re talking about. You need to speak as a PhD versus a student. The discussion chapter is similar to the empirical/results chapter, but you’re building on those results to push the new information that you learned, prior to making your conclusion.
• Conclusion : Here, you take a step back and reflect on what your original goals and intentions for the research were. You’ll outline them in context of your new findings and expertise.

Tips for your PhD Thesis Format

As you put together your PhD thesis, it’s easy to get a little overwhelmed. Here are some tips that might keep you on track.

• Don’t try to write your PhD as a first-draft. Every great masterwork has typically been edited, and edited, and…edited.
• Work with your thesis supervisor to plan the structure and format of your PhD thesis. Be prepared to rewrite each section, as you work out rough drafts. Don’t get discouraged by this process. It’s typical.
• Make your writing interesting. Academic writing has a reputation of being very dry.
• You don’t have to necessarily work on the chapters and sections outlined above in chronological order. Work on each section as things come up, and while your work on that section is relevant to what you’re doing.
• Don’t rush things. Write a first draft, and leave it for a few days, so you can come back to it with a more critical take. Look at it objectively and carefully grammatical errors, clarity, logic and flow.
• Know what style your references need to be in, and utilize tools out there to organize them in the required format.
• It’s easier to accidentally plagiarize than you think. Make sure you’re referencing appropriately, and check your document for inadvertent plagiarism throughout your writing process.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

The resources in this section are designed to provide guidance for the first steps of the thesis or dissertation writing process. They offer tools to support the planning and managing of your project, including writing out your weekly schedule, outlining your goals, and organzing the various working elements of your project.

Weekly Goals Sheet (a.k.a. Life Map) [Word Doc]

This editable handout provides a place for you to fill in available time blocks on a weekly chart that will help you visualize the amount of time you have available to write. By using this chart, you will be able to work your writing goals into your schedule and put these goals into perspective with your day-to-day plans and responsibilities each week. This handout also contains a formula to help you determine the minimum number of pages you would need to write per day in order to complete your writing on time.

Setting a Production Schedule (Word Doc)

This editable handout can help you make sense of the various steps involved in the production of your thesis or dissertation and determine how long each step might take. A large part of this process involves (1) seeking out the most accurate and up-to-date information regarding specific document formatting requirements, (2) understanding research protocol limitations, (3) making note of deadlines, and (4) understanding your personal writing habits.

Creating a Roadmap (PDF)

Part of organizing your writing involves having a clear sense of how the different working parts relate to one another. Creating a roadmap for your dissertation early on can help you determine what the final document will include and how all the pieces are connected. This resource offers guidance on several approaches to creating a roadmap, including creating lists, maps, nut-shells, visuals, and different methods for outlining. It is important to remember that you can create more than one roadmap (or more than one type of roadmap) depending on how the different approaches discussed here meet your needs.

Below are some very important guidelines to pay attention to while writing your doctoral thesis. Make yourself familiar with them to avoid future inconvenience and frustration.

Please read and adhere to the document final thesis admission checklist when

compiling your thesis and submit the completed form together with the other requisite documents when uploading your thesis.

Before writing up, chat to your supervisor as he or she can provide you with some useful suggestions on best practices. Furthermore, it might be a good idea to have a look at some recent doctoral theses (use templates from 2015 and onwards).. 

Remember your obligation to report your thesis progress at least once a year (please see forms below).

Your thesis must be submitted as PDF/A file. Therefore, please read the guidelines for PDF/A conversion before you begin your writing.

The template file for the conversion to PDF/A must be in one of these formats:

• Microsoft Word
• PowerPoint 
• WordPerfect 
• OpenOffice (ODT)
• Hangul (HWP)
• Google Docs (submitted via the Google Drive submission option), 
• plain text files 

Some points on content

The thesis must include one English and one German abstract (about one A4 page each) as well as a table of contents.

Optimally, theses should end with your curriculum vitae that additionally contains a list of publications.

Pay special attention to the cover page , which must include:

• The MedUni Wien logo in the upper right hand side corner, thereafter centered
• Title of the doctoral thesis (avoid abbreviations)
• Doctoral Thesis at the Medical University of Vienna for obtaining the degree of Doctor of Philosophy/Doctor of Medical Science (choose the correct degree)
• Submitted by: your name
• Under the supervision of: the name of your supervisor (including the institute/center/department)
• Place and date of submission

Some suggestions for formatting the thesis:

• Font type: Arial
• Font size: 11 pt
• Line spacing: 1.5 lines
• Margin: 2-3 cm
• Pages should be printed only on one side

Your name must appear on the spine of the bound thesis

First author publication

In the PhD Program UN094, it is required to publish at least one first-author, peer-reviewed, original research paper, which must be accepted for publication before your defense. To avoid a situation whereby a single published paper might be inappropriately used to generate more than one degree (double dipping), it should be made clear to equal first authors who are both doctoral students that in the case whereby no additional research papers have been published separately, only one will be able to use the shared publication for their thesis.

Publication-based doctoral thesis

In addition to a monograph, a doctoral thesis may also be compiled using (one or more) published papers (recommended). Please note that the work has to be submitted formally as a doctoral thesis, including a cover page, German and English abstracts, an introduction, a discussion, and references. Additional sections apply. As a rule of thumb, the introduction and discussion chapters should comprise about 50% of the total length of the doctoral thesis.

You should concentrate on the main theme, ideally related to your first-author publication, whereby possible additional themes may be addressed as further outcomes/projects. Moreover, the contribution to the research work presented in the thesis of the candidate as well as other collaborators/co-authors should be declared so as to prevent any future misunderstandings about who did what.

Please see "thesis outline" below.

Plagiarism Check

A plagiarism check takes place after the submission of the completed doctoral thesis and before the thesis is sent out to the reviewers. Please read the information on plagiarism. Avoid any form of plagiarism and self-plagiarism and be aware of the serious consequences that result from this form of misconduct. You can find further information about this subject in the download section below.

Doctoral theses

What is a doctoral thesis.

A doctoral thesis is an original piece of research in any area of knowledge that is produced by a doctoral candidate under the supervision of a doctoral degree holder with accredited research experience. With the thesis, doctoral candidates must demonstrate their ability to develop an independent work in research, development and innovation.

The doctoral thesis is assessed at a public defence in which the doctoral candidate presents the research to an examination committee of experts on the subject.

In the following figure, you can identify the stages and mechanisms that, in accordance with the prevailing legislation , the UPC establishes to guarantee the quality and publicity of doctoral theses produced on all of its programmes

Rank-Based Analyses and Designs with Clustered Data

Clustered data are common in biomedical research. It is often of interest to evaluate the correlations within clusters and between variables with clustered data. Conventional approaches, including intraclass correlation coefficients (ICCs) and Pearson correlations, are commonly used in analyses with clustered data. However, these conventional approaches are sensitive to extreme values and skewness. They also depend on the scale of the data and are not applicable to ordered categorical data. In this dissertation, we define population parameters for the rank ICC and between- and within-cluster Spearman rank correlations. These definitions are natural extensions of the conventional correlations to the rank scale. We show that the total Spearman rank correlation approximates a weighted sum of between- and within-cluster Spearman rank correlations, with weights determined by the rank ICCs of the two random variables. We also describe estimation and inference for these four rank-based correlations, conduct simulations to evaluate the performance of our estimators, and illustrate their use with real data examples. Furthermore, we apply the rank ICC in the design of clustered randomized controlled trials (RCTs), proposing unified and simple sample size calculations for cluster RCTs with skewed or ordinal outcomes. Our calculation involves inflating the sample size for an adequately powered individual RCT for an ordinal outcome with a design effect that incorporates the rank ICC. For continuous outcomes, our calculation sets the number of distinct ordinal levels to the sample size. We show that with continuous data, our calculations closely approximate more complicated sample size calculations based on clustered Wilcoxon rank-sum tests. We conduct simulations to evaluate our calculations’ performance and illustrate their use in the design of two cluster RCTs, one with a skewed continuous outcome and a non-inferiority trial with an irregularly distributed count outcome.
