{Reference Type}: Systematic Review {Title}: Psychedelics and Evidence-based Psychotherapy: A Systematic Review with Recommendations for Advancing Psychedelic Therapy Research. {Author}: Leone L;McSpadden B;DeMarco A;Enten L;Kline R;Fonzo GA; {Journal}: Psychiatr Clin North Am {Volume}: 47 {Issue}: 2 {Year}: 2024 Jun {Factor}: 2.832 {DOI}: 10.1016/j.psc.2024.02.006 {Abstract}: Administration of psychedelics for mental health treatment, typically referred to as "psychedelic-assisted therapy," is a broad term with a very heterogeneous implementation. Despite increasing interest in the clinical application of psychedelic compounds for psychiatric disorders, there is no consensus on how to best integrate the psychedelic experience with evidence-based psychotherapeutic treatment. This systematic review provides a timely appraisal of existing approaches to combining psychotherapy with psychedelics and provides clear recommendations to best develop, optimize, and integrate evidence-based psychotherapy with psychedelic administration for straightforward scientific inference and maximal therapeutic benefit.
