This is an ongoing experimental project to help therapists, clinicians, educators, and students navigate evidence-based research in a fun and interactive way.

Background Story

​

Ever since I started using the Gapminder Motion Chart created by Hans Rosling—the late Swedish physician and international health professor—I became fascinated with data and with how much more meaning we can extract when we visualize it. Recently, I learned about the Metapsy project, created by a team in the Netherlands. In Metapsy, the Meta-Analytic Research Domain (MARD) is used to build a database of meta-analyses of randomized controlled trials (RCTs) on psychotherapy outcomes across a range of diagnostic categories.

​​​

​

This website is designed to transform that database into a living, interactive tool that lets you explore effect sizes (the magnitude of difference between two groups i.e. treatment vs control)  In clinical research, it tells you whether a treatment’s impact is large enough to matter in real practice, not just whether it is statistically significant.

​

How do you interpret the bubble chart?

​​

On the interactive bubble chart, the x-axis shows the trend in research over time. The color of each bubble represents a particular therapy type (you can toggle therapies on and off), and the size of each bubble reflects the sample size of that study. You can also click on links to the original metapsy.org to view detailed information about each study.
