The case for an integrative model: Hypotheses and rationale for integrative MDMA-Assisted Psychotherapy (IMAP)

Psychedelics January 8, 2026 Rachel Yehuda, Amy Lehrner, Miryam Sperka et al. 2 citations

The original manual for MDMA-assisted therapy (MDMA-AT) for PTSD, developed by the Multidisciplinary Association for Psychedelic Studies (MAPS), introduced concepts like “inner healing intelligence” from transpersonal traditions, which lacked clear grounding in trauma science and were difficult to standardize. In response, a new model called Integrative MDMA-Assisted Psychotherapy (IMAP) is proposed. IMAP is a principle-guided, patient-driven approach rooted in humanistic and trauma-focused psychotherapy. It offers flexible, relationally attuned support for nonlinear therapeutic processes, drawing on contemporary PTSD theories and evidence-based trauma interventions while retaining experiential approaches. The model invites empirical study to determine essential therapeutic elements in psychedelic contexts.

Balancing Innovation and Evidence: Reflections on Structured Protocols in MDMA-Assisted Therapy Versus a Principle-Guided, Patient-Directed Approach

Psychedelic Medicine March 10, 2026 Amy Lehrner, Miryam Sperka, Lauren Lepow et al. 1 citation

MDMA-assisted therapy for post-traumatic stress disorder has shown strong clinical effects, high response rates, and low dropout when using a principle-guided, patient-directed model that includes nondrug preparatory and integrative sessions. This perspective argues that embedding MDMA into highly structured, manualized cognitive-behavioral treatment protocols may misapprehend the therapy's synergistic nature, blunt its transformative effects, and potentially cause harm. The field should prioritize research on real-world evidence, treatment optimization, and mechanisms of action of this distinct patient-directed model rather than immediately adapting existing protocols.
