The Role of Personal Experience for the Therapeutic Attitude in the Context of Substance-assisted Therapy Training

Sponsor: Felix Mueller

View on ClinicalTrials.gov

Summary

The study investigates two groups of participants of the SÄPT therapist's training starting in October 2022. The overall objective is to investigate the risks and benefits of personal experience (PE) with substance-induced altered states of consciousness for physicians or psychotherapists in the context of a training course for substance-assisted therapy. Specifically, the study aims to assess changes in therapeutic attitude and other factors important in interactions between patients and therapists (such as empathy and cognitive flexibility).
