Psilocybin, but not the antidepressant escitalopram, reduced rumination and thought suppression in people with major depressive disorder six weeks after treatment. In a randomized trial of 59 participants, only those given psilocybin showed significant decreases in both maladaptive coping strategies. Among treatment responders, thought suppression decreased exclusively in psilocybin responders, while rumination decreased in both psilocybin and escitalopram responders. Reductions in rumination and thought suppression correlated with ego dissolution and psychological insight during psilocybin sessions, suggesting distinct therapeutic mechanisms for the two treatments.
