Examining Psychological Science Through Systematic Meta-Method Analysis
Traditionally, meta-analysis of psychological studies has involved synthesizing effect sizes from a set of systematically selected studies. Meta-method analysis informs this synthesis with an examination of the study corpus's operationalization of constructs, observation and measurement choices, and analytic methodologies.

What is meta-analysis?
Meta-analysis is a research process used to systematically synthesise or merge the findings of single, independent studies, using statistical methods to calculate an overall or 'absolute' effect. 2 Meta-analysis does not simply pool data from smaller studies to achieve a larger sample size. Analysts use well recognised, systematic methods ...
Adherence to electronic health tools among vulnerable groups
In the meta-analysis, we used the adherence rate as an effect size measure. The adherence rate is defined as the number of people who are repetitive users (ie, use the eHealth tool more than once). We also performed a meta-regression analysis to examine how different design and implementation characteristics influenced the adherence rate.
