Comprehensive Meta-Analysis

software image

Comprehensive Meta-Analysis (CMA) is a powerful computer program for meta-analysis. The program combines ease of use with a wide array of computational options and sophisticated graphics.


"I am an advanced graduate student in clinical psychology, and CMA software was integrated into a meta‐analysis course I recently took. I feel very fortunate to have been trained in meta‐analyses at a time when we have this software because CMA is easy and, I dare say, fun to use. Rather than spending countless hours computing my own effect sizes and creating syntax, the program did it for me, which allowed me to spend my time really looking at the data, both graphically and numerically. I bought CMA for myself and would recommend it to anyone looking to learn the art of meta‐analysis."

Rachel Hershenberg


"Comprehensive Meta‐Analysis (CMA) is an excellent statistical software program. CMA is very userfriendly, provides essential elements of analyses required for synthesis of quantitative studies, evaluates publication bias statistically and graphically, and offers technical support. I have used CMA for a recent study I conducted with my professor at the University of Maryland, The reliability and validity of the Anticipated Turnover Scale across studies of RNs in the US (in press). I highly recommend the Comprehensive Meta‐Analysis software program for anyone conducting meta‐analytic research."
