Effects of MDMA-assisted therapy for PTSD on self-experience

This re-analysis of an RCT of MDMA-assisted therapy for PTSD finds that study participants (n=90) had significant improvements in the measures of self-experience (e.g. alexithymia -; the inability to identify & describe emotions experienced by oneself). The change in scores of self-experience correlates with recovery from PTSD.
