Therapeutic Alliance and Rapport Modulate Responses to Psilocybin Assisted Therapy for Depression

Frontiers in Pharmacology March 31, 2022 Roberta Murphy, Roberta Murphy, Hannes Kettner et al. 229 citations

In a trial comparing psilocybin-assisted therapy to escitalopram for moderate-to-severe depression, a stronger therapeutic alliance with the therapist predicted greater emotional breakthrough and mystical-type experiences during psilocybin sessions, and these experiences in turn predicted larger reductions in depression symptoms six weeks after treatment. Emotional breakthrough during the first session strengthened the alliance before the second session, while a weaker alliance before the second session directly predicted higher depression scores at the endpoint, independent of the acute psychedelic experience. The findings suggest the therapeutic relationship plays a key role in shaping both the quality of the psychedelic experience and clinical outcomes.

Ceremonial Psychedelic Experiences and Changes in Mental Health Outcomes in Those with Adverse Childhood Experiences

Psychedelic Medicine December 15, 2025 M. Mehmood, Rebecka Bremler, M. Spriggs et al.

People who experienced more adverse childhood experiences (ACEs) showed greater improvements in mental well-being, reductions in experiential avoidance, and lower trait anxiety after participating in psychedelic ceremonies compared to those with fewer ACEs. Higher ACE scores were also linked to stronger emotional breakthrough and mystical experiences during the psychedelic session. Among individuals with four or more ACEs, those who reported stronger mystical or emotional breakthrough experiences had better well-being at two and four weeks afterward, and mystical experiences were linked to less experiential avoidance while emotional breakthrough was linked to less anxiety at four weeks. However, the acute experiences did not significantly change how ACEs affected mental health outcomes overall.
