This preprint study (2022) interviewed experts in the fields of psychiatry, clinical psychology, medicine and the effects of psychedelics (n=12) to determine if there was agreement in expert opinion. Experts agreed that psychedelic-assisted psychotherapy (PAP) is not necessarily contraindicated for all individuals with psychotic symptoms and that highly supportive PAP may be of benefit to some individuals experiencing psychosis.
Abstract
“Background: Currently, personal or familial histories of psychotic symptoms are exclusionary criteria for most psychedelic clinical trials, studies, and treatment programs. This study sought to determine why such an exclusion exists, what the implications of the exclusion criteria are, and if there was agreement in expert opinion.
Methods: In-depth interviews with 12 experts in the fields of psychiatry, clinical psychology, medicine, and the effects of psychedelics and entheogens were conducted in an expert consultation format. Interviews were transcribed and themes were produced using an Interpretative Phenomenological Analysis (IPA) approach.
Results: We found that while the exclusion criteria may be justified for psychedelic protocols that provide insufficient psychological support for participants, there was agreement that psychedelic-assisted psychotherapy is not necessarily contraindicated for all individuals with psychotic symptoms. Results suggest that highly supportive psychedelic-assisted psychotherapy may be of benefit to individuals experiencing symptoms of psychosis. Potentially relevant factors for predicting treatment outcomes include specific symptom endorsement, illness duration, symptom severity, quality of the therapeutic alliance, the role of trauma in symptom aetiology and perpetuation, and the level of other supports in the life of the client.
