A multidisciplinary working group identified 54 potential adverse events that warrant systematic assessment in psychedelic-assisted therapies, finding that existing measurement tools substantially fail to cover these constructs. The group developed recommendations for when and how to assess these adverse events across preparation, dosing, integration, and follow-up phases, and demonstrated a preliminary assessment protocol. The framework addresses the need to capture post-acute dosing adverse events, accounting for both the pharmacotherapy and psychotherapy components of psychedelic-assisted therapy, as well as documented impacts on worldviews and spirituality.
A multidisciplinary working group identified 53 potential adverse events (AEs) specific to psychedelic-assisted therapies (PATs) that current assessment tools miss. Existing measures cover only a fraction of these constructs. The group recommends new assessment methods—including patient, clinician, and informant reports—and specifies when to measure AEs across preparation, dosing, integration, and follow-up phases. The framework addresses gaps in capturing post-acute dosing effects, including changes in worldview and spirituality, which distinguish PAT from other treatments.
