Abstract
Psychedelic-assisted therapy (PAT) is moving from research settings towards broader implementation. During this transition, the therapist role is being formalised before the developmental pathways into the role are well understood. Existing clinicians are being selected, trained, and authorised to practise in a field marked by an emergent knowledge base and the convergence of multiple cultural and therapeutic traditions. Yet little is known about how therapists come to enter, navigate, and ultimately inhabit the PAT therapist role. This developmental question is central to therapist preparation, but remains undertheorised: what does becoming a PAT therapist involve, how does it unfold, and what supports it? This paper draws on contemporary professional identity formation (PIF) theory as a conceptual lens to guide and interpret research on future PAT therapist development. Together with relevant work on psychotherapist development and reflective practice, this lens approaches movement into PAT as a process of professional reconfiguration. It directs attention to what carries forward from prior training, what may need revision, when personal experience becomes a clinical resource rather than unexamined conviction, and how legitimacy is negotiated across diverse practice traditions.PAT may also stretch existing PIF theory. Unlike many contexts in which PIF has been studied, therapists generally enter PAT as already established practitioners. They also enter a field that lacks a single, coherent identity or community of practice. In addition, some altered-state experiences may change the standpoint from which therapists later reflect on their own development. PAT therapist development may therefore require an expanded account of PIF, capable of theorising formation when both the professional role and the reflecting self remain in flux.
