Group format psychedelic-assisted therapy interventions: Observations and impressions from the HOPE trial

Abstract

Psilocybin-assisted psychotherapy has demonstrated significant promise as a treatment for depression, anxiety, and existential distress associated with serious medical illness and has generally been employed on an individual basis, which presents challenges for scaling and resource availability. There are also compelling theoretical reasons to suggest that group-based formats-if utilized in a thoughtful fashion-might offer unique or enhanced therapeutic benefits for certain conditions or populations. The HOPE trial is an IRB-approved open-label feasibility and safety pilot study of psilocybin enhanced group therapy in patients with a DSM-5 depressive disorder associated with a cancer diagnosis completed at the Huntsman Cancer Institute (HCI) in Salt Lake City, Utah (HOPE: A Pilot Study of Psilocybin Enhanced Group Psychotherapy in Patients with Cancer). We report here qualitative survey-based data, impressions, and suggestions for group-based psychedelic-assisted therapy interventions based on our observations to inform future studies.Patients with a DSM-5 depressive disorder with an underlying cancer diagnosis were recruited from HCI by referral from oncology providers, palliative care, and social work. Following screening and consenting, 4-6 participants per cohort (with three total cohorts) were enrolled in a protocol involving 3 120 min group preparatory sessions, a single high-dose (25 mg) group psilocybin session, and 3 subsequent group integration sessions. Primary clinical outcomes are still in process of data collection and analysis. Qualitative data was gathered from patient written reports and a survey administered at 2 weeks post intervention. Qualitative reports were also gathered from the therapist team at a post-study group process session.We report here results from a qualitative survey of participant experiences with group format study design, as well as impressions and guidelines for group format and group psychotherapeutic process to inform other studies pursuing group-based interventions in psychedelic therapy. Suggestions are provided for protocol design, screening processes, space considerations, therapist team structure, group process, music, timeline, as well as potential issues and challenges.
