Dr. Casey Paleos Co-Authors Landmark Chapter in the American Journal of Psychiatry: Shaping the Future of MDMA-Assisted Psychotherapy

At InnerMost, our mission is to bring the highest standards of safety, compassion, and clinical excellence to psychedelic-assisted therapy. Today, we’re proud to share a milestone that reflects this commitment: our Chief Medical Officer, Dr. Casey Paleos, has co-authored a pivotal chapter in the American Journal of Psychiatry, one of the most respected and influential psychiatric journals in the world.

Co-authored with Michael D. Alpert, M.D. and Chantelle Thomas, Ph.D., the chapter, titled “Inner-Directed Therapy in MDMA-Assisted Psychotherapy,” arrives at a decisive moment for the field. As MDMA-assisted psychotherapy continues to be evaluated for federal approval, this work provides critical clarity on the therapeutic model at the center of decades of clinical trials: Inner-Directed Therapy (IDT).

Why This Chapter Matters

For years, IDT has served as the therapeutic backbone of clinical trials investigating MDMA for PTSD, including the Phase 3 studies that demonstrated remarkable outcomes and comparably low dropout rates. Yet the model has recently come under scrutiny from outside commentators, many of whom misunderstand its foundations or conflate it with isolated incidents of unethical practice that violated—not exemplified—the model.

The chapter addresses these misconceptions head-on, offering a rigorous, evidence-based synthesis of IDT’s safety, structure, and clinical impact. Notably:

  • IDT is highly standardized in clinical trials, with strict adherence protocols, video-review oversight, and independent fidelity ratings exceeding 90%.

  • Its efficacy rivals leading PTSD treatments, with effect sizes comparable to cognitive processing therapy and prolonged exposure—while demonstrating significantly lower dropout rates.

  • Its core principle—the inner healing intelligence—reflects a trans-theoretical, patient-centered orientation, shared across many established psychotherapy traditions.

  • Supportive and therapeutic touch, often misunderstood by critics, is governed by strict informed-consent procedures and must remain within professional ethical guidelines.

Rather than encouraging specific types of experiences, IDT equips patients to meet whatever arises—emotional, somatic, relational, or nonlinear—during MDMA or placebo sessions. The model honors autonomy, builds resilience, and supports individuals in connecting with their own capacity for healing.

Shaping the Next Generation of Therapists

This chapter goes beyond clarification. It lays groundwork for the future.

As the field stands at a crossroads—especially following the FDA’s 2024 request for additional data—this comprehensive, scientifically grounded articulation of IDT will influence how future studies are designed, how safety and ethics are taught, and how therapists are trained for years to come.

Educational programs, training institutes, and clinical researchers will look to this chapter as a reference point for what safe, effective, patient-led care looks like when paired with MDMA.

A Reflection of InnerMost’s Values

Dr. Paleos’s contribution to the American Journal of Psychiatry is more than a publication—it’s a testament to the standards we uphold at InnerMost: integrity, scientific rigor, and a deep respect for each person’s innate healing capacity.

As we continue providing ketamine-assisted therapy in New York City, we remain proud that our work is guided by leaders shaping the very future of psychedelic medicine.
