Rosalind Watts

Rosalind Watts is a clinical psychologist and researcher principally associated with the Centre for Psychedelic Research/Imperial Psychedelic Research Group. Her work sits at the intersection of clinical trials, qualitative research and psychotherapy theory, with a focus on how psychedelic-assisted interventions produce clinically meaningful change in people with treatment-resistant depression and related conditions. Watts has been a core member of clinical trials of psilocybin for depression and contributed to landmark follow-up studies and comparative trials that helped re-establish clinical evidence for psychedelic-assisted therapies.

Watts has contributed methodological and conceptual advances to the field: she is co‑author on studies validating the Emotional Breakthrough Inventory, on qualitative analyses of increased connectedness and acceptance after psilocybin, and on quantitative work linking post‑psychedelic reductions in experiential avoidance to decreases in depression severity and suicidal ideation. She has also advanced the application of the psychological flexibility model to support psychedelic-assisted therapy and has published on integration and therapist practice, helping translate trial findings into practical therapeutic frameworks for clinical use.
