The Psychological Support Model in Psilocybin Research: Psychotherapy in Disguise?

Psychiatric Research and Clinical Practice January 14, 2026 Celia Faye Jacobsen, Dea Siggaard Stenbæk, Stig Poulsen et al. 3 citations

The Compass Psychological Support Model (CPSM) used in psilocybin trials is arguably a form of bona fide psychotherapy, not merely psychological support. Its components—psychoeducation, trust, present-moment focus, and client autonomy—align with humanistic-experiential therapies like client-centered and emotion-focused therapy. These methods, such as building therapeutic alliance and reducing experiential avoidance, have established links to improved outcomes in both general psychotherapy and psilocybin treatments. Framing the CPSM as non-therapeutic undermines methodological transparency and may obscure its contribution to efficacy. Recognizing it as psychotherapy could enable optimization of therapist skills and client factors, enhancing treatment outcomes.

Psilocybin and Motor Function: A Triple‐Blind, Dose‐Finding Study in Healthy Participants

Psychiatric Research and Clinical Practice July 23, 2024 Chiranth Bhagavan, Richard Kanaan, Olivia Carter et al. 2 citations

A protocol for the first study testing whether movement tasks can be performed safely while under the influence of psilocybin. Twelve healthy participants will each receive three different doses (5 to 20 mg) in a randomized, blinded order at least one week apart. Motor function, safety, brain activity via fMRI, and subjective experience will be measured during the acute drug effects. The study aims to inform future research combining psychedelics with motor retraining for conditions involving motor dysfunction.

Real‐World Effectiveness and Cost‐Differential of Intranasal Esketamine Versus Intramuscular Ketamine

Psychiatric Research and Clinical Practice July 2, 2026 Kush V. Bhatt, Tara Austin, Danny Alam et al.

Intramuscular (IM) ketamine is as effective as intranasal (IN) esketamine for treatment-resistant depression, with comparable safety and a dramatically lower cost. In a retrospective cohort of 179 Veterans, the difference in depression symptom improvement was only 0.04 points on the PHQ-9, well within the non-inferiority margin. PTSD symptom reductions were also similar, and rates of emergency department visits or hospitalizations did not differ significantly. The cost per eight-treatment course was $6069 for IN esketamine versus $647 for IM ketamine, driven primarily by the cost of the nasal spray. These results indicate that IM ketamine could be a high-value alternative that expands access to care.
