But does it work?

Results, graphs, numbers. They're nice to look at.

But does Group EMDR therapy work?

In short, yes. Here is an automatically updating calculation of the effect size based on the measured psychological conditions. The results are displayed as Cohen's d, a commonly used statistic in psychology. Effect size can be visualised using this tool from Dr. Kristoffer Magnusson. Input a value from the chart below, and you will see a visual explanation of the results, which are updated in real-time as participants complete treatment with us.
