Abstract
Research on the therapeutic effects of psychedelics in psychiatry, commonly referred to as Psychedelic-Assisted Therapy (PAT), has expanded substantially in recent years. The context-dependent nature of psychedelics has sparked discussion about the importance of the psychotherapeutic environment in achieving beneficial outcomes. This study explores the contribution of psychotherapeutic factors on PAT in Switzerland, where psychedelic treatments can be implemented within long-term clinical frameworks. Seven semi-structured interviews were conducted with Swiss therapists to explore how they frame psychedelic treatments and the role of the psychotherapeutic setting in facilitating therapeutic outcomes. Thereby, individual experiences of the patients as reported by the therapists, were particularly considered. Thematic analysis identified two main themes, each with several sub-themes. The first theme revealed that while psychotherapeutic techniques are adapted to PAT, they retain similarities to non-psychedelic psychotherapy practices, supporting patients in having meaningful therapeutic experiences. The second theme describes a synergistic relationship between psychedelics and psychotherapy, amplifying underlying general psychotherapeutic factors such as trust, a sense of profundity, and the emergence of therapeutic experiences. The interviewed therapists agreed that psychedelics work as unspecific catalysts for psychotherapeutic processes, while still acknowledging the potential for psychopharmacological effects or the interaction between psychedelics and psychotherapy to create unique psychotherapeutic processes. Findings from our sample suggest that, for specific indications, incorporating psychedelics into long-term psychotherapeutic treatment may strengthen therapeutic processes. Future research could investigate the efficacy of PAT within the framework of specific psychotherapeutic modalities or in different settings, including prospective quantitative assessments of outcomes. Ultimately, clarifying mechanisms of action of PAT may help to enhance its efficacy and potentially to integrate psychedelic treatments into mainstream mental health care.
