Over the past decades, psychotherapy for Prolonged Grief Disorder (PGD)—a condition marked by intense and persistent grief following the death of a loved one—has garnered increasing attention. Despite this, evidence-based approaches to prevent or alleviate PGD remain scarce and are not always effective (Hedges' g: 0.41-0.45).
In this talk, I will present outcomes from a three-arm, non-randomized clinical study comparing a constructivist psychotherapeutic protocol assisted with ayahuasca to the same protocol without ayahuasca and to a no-treatment control group (n = 84). Our primary outcome is grief severity, measured by the Texas Revised Inventory of Grief (TRIG) at baseline, post-treatment, and a 3-month follow-up. Additionally, we will present results on PGD symptoms, quality of life, post-traumatic growth, psychological flexibility, meaning-making, and self-belief consistency.
We anticipate that this trial will make a significant contribution to bereavement care, potentially reducing the time needed for grieving individuals to receive evidence-based support. Beyond the context of bereavement, this study may enhance our understanding of psychedelic-assisted psychotherapy as a transdiagnostic intervention, thereby helping to reduce the global mental health burden.
Débora Gonzalez, Ph.D., is a Professor in the Department of Clinical Psychology at Isabel I University (Spain) and a researcher at the Fundación Sant Joan de Deu. She has co-authored several scientific papers and book chapters on ayahuasca, 2C-B, Salvia divinorum, and research chemicals. Her primary research interest lies in the potential of psychedelics to transform the conception of death in Western society. She is currently conducting a clinical study to assess the potential of ayahuasca-assisted psychotherapy in preventing prolonged grief disorder.
