Abstract Rationale: Major depressive disorder (MDD) shows marked sex differences in prevalence, symptomatology, and treatment response. However, women remain underrepresented in many clinical trials, and sex-specific treatment outcomes are rarely examined. Objectives This study reanalyzed data from a randomized controlled trial comparing psilocybin and escitalopram for MDD to evaluate sex...

This commentary critically examines the interpretation and analytic choices in Goodwin and colleagues’ recent analysis of therapeutic alliance in psilocybin treatment for treatment-resistant depression. While the authors conclude that alliance did not meaningfully contribute to treatment efficacy, we argue that this interpretation is not supported by the reported results, which are, in...

Psilocybin-assisted therapy has emerged as a promising treatment for major depressive disorder, but little attention has been paid to the psychotherapy that adjoins psilocybin. Providing an adjunctive psychotherapy that is manualized and evidence-based may make psilocybin treatment more acceptable, effective, and disseminable. We examined the acceptability, feasibility, and clinical outcomes of...

However, questions need to be addressed regarding the relationship between dosage and therapeutic outcomes, such as the recommended dose range and frequency for optimal practice as well as the dose-dependent adverse effects. OBJECTIVE: (1) to assess the effectiveness and...
