A new questionnaire, the General Change Mechanisms Questionnaire (GCMQ), reliably measures five psychotherapy processes—resource activation, therapeutic relationship, problem actuation, clarification, and mastery—during psychedelic experiences. Validated in 1153 English-speaking and 714 German-speaking users, the GCMQ showed good internal consistency and convergent validity. Experiences varied with setting and use motives (therapeutic, hedonic, escapist). Resource activation, clarification, and mastery moderated the link between stressful life events and well-being, suggesting potential therapeutic benefits. Five distinct user profiles emerged, which may inform clinical use and harm reduction.
