At a glance, it looks like this broadly matched the demographics of the broader EA Survey, except for gender (women were dramatically over-represented in the mental health survey) and engagement (people who took the mental health survey were much more highly engaged).
I agree with you that this survey will also very likely select for people with more of an interest in mental health and perhaps suffering from mental health issues. I imagine this might explain the relatively low life satisfaction you found:
the average overall life satisfaction in the EU was 7.3, while in our survey it was 6.6. The life satisfaction of people in the EA community who filled out this survey in 2023 seems to be lower than the one of the typical EU member in 2018, and is similar to the one of people in Greece or Hungary (see Figure 1).
Thanks for putting this together!
