Combining Cognitive-Behavioral Conjoint Therapy for PTSD with 3,4-Methylenedioxymethamphetamine (MDMA): A Case Example.

Journal of psychoactive drugs January 1, 2019 Anne C Wagner, Michael C Mithoefer, Ann T Mithoefer et al. 92 citations

Combining Cognitive Behavioral Conjoint Therapy for PTSD (CBCT) with MDMA-assisted psychotherapy in a small pilot trial can reduce PTSD symptoms and improve relationship satisfaction. A case study of one couple with a severe trauma history, representative of the trial participants, details the integrated methodology and the couple's treatment experience. The article describes how these two therapeutic modalities were merged and demonstrates that the combination produces positive outcomes, including symptom reduction and enhanced relationship functioning.

MDMA-facilitated cognitive-behavioural conjoint therapy for posttraumatic stress disorder: an uncontrolled trial.

European journal of psychotraumatology December 7, 2020 Candice M Monson, Anne C Wagner, Ann T Mithoefer et al. 90 citations

A small pilot study tested whether adding MDMA to cognitive-behavioural conjoint therapy (CBCT) for PTSD is safe and effective. Six couples, where one partner had PTSD, completed a condensed 7-week CBCT protocol that included two sessions where both partners received MDMA. No serious side effects occurred. PTSD symptoms improved substantially, as rated by clinicians, patients, and partners (effect sizes d = 1.85–3.59). Patients also showed improvements in depression, sleep, emotion regulation, and trauma-related beliefs. Relationship adjustment and happiness improved for both patients and partners (d = 0.64–2.79). MDMA may enhance CBCT's benefits for individuals with PTSD and their partners.

How does psilocybin therapy work? An exploration of experiential avoidance as a putative mechanism of change.

Journal of affective disorders August 1, 2023 Richard J Zeifman, Anne C Wagner, Candice M Monson et al. 56 citations

In a double-blind randomized controlled trial comparing psilocybin therapy (two 25 mg sessions plus daily placebo for six weeks) with escitalopram (two 1 mg psilocybin sessions plus 10-20 mg daily escitalopram for six weeks) among 59 individuals with major depressive disorder, reductions in experiential avoidance mediated improvements in well-being, depression severity, suicidal ideation, and trait anxiety only in the psilocybin group. Exploratory analyses indicated that these improvements (except for suicidal ideation) occurred serially through increased connectedness. Experiences of ego dissolution and psychological insight predicted reductions in experiential avoidance. The findings support reduced experiential avoidance as a mechanism underlying psilocybin therapy's positive outcomes.

Relational and Growth Outcomes Following Couples Therapy With MDMA for PTSD.

Frontiers in psychiatry January 1, 2021 Anne C Wagner, Rachel E Liebman, Ann T Mithoefer et al. 40 citations

Healing from trauma happens in relationships, and PTSD affects more than just the diagnosed individual. In a pilot trial of Cognitive Behavioral Conjoint Therapy (CBCT) for PTSD combined with two MDMA psychotherapy sessions, six romantic couples where one partner had PTSD showed improvements across multiple areas. Both partners reported increases in post-traumatic growth, relational support, and social intimacy. Partners also reported less behavioral accommodation and conflict, while patients with PTSD reported better psychosocial functioning and empathic concern. These gains lasted through a 6-month follow-up. The findings suggest that combining CBCT with MDMA can improve relational and growth outcomes, supporting a dyadic approach to holistic trauma recovery.
