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.
Anorexia nervosa is a severe psychiatric condition with few approved treatments. This paper describes how individuals with lived experience of anorexia nervosa helped shape a pilot study of psilocybin-assisted therapy through two online focus groups involving eleven people, and presents the protocol for that study at Imperial College London. Twenty female participants aged 21–65 with a body mass index of 15 kg/m² or above will receive three oral doses of psilocybin (up to 25 mg) over six weeks, supported by psychological preparation and integration, with a 12-month remote follow-up.
Clinical research suggests significant efficacy for psychiatric disorders that have traditionally been hard to treat, with psychedelic-assisted psychotherapy moving from a fringe subject to a significant new treatment method that all psychotherapists should be aware of and some may develop into a special interest.
