Abstract
By fostering certain self-transcendent experiences (STE)—those characterized by interconnectedness and other-oriented emotions—3,4-Methylenedioxymethamphetamine (MDMA)-assisted therapy (MDMA-AT) has been hypothesized to disrupt social anxiety disorder maintenance processes, including negative self-focus, self-criticism, and isolation, thereby enhancing wellbeing. This secondary analysis used data from a randomized waitlist controlled trial of MDMA-AT for generalized social anxiety disorder (N = 20; NCT05138068). It characterized STE during MDMA-AT and examined their relationships with social anxiety symptoms and wellbeing outcomes. Participants reported on STE following two MDMA sessions. Outcomes (social anxiety, gratitude, belonging, purpose in life) were measured at baseline and post-treatment (16 weeks). Paired-samples t-tests examined changes across sessions and pre-to-post treatment, and regression analyses tested whether in-session experiences predicted outcome improvements. Sessions elicited blissful states, and positive and ST emotions, with few negative emotions reported. In-session experiences, especially connection-oriented STE, predicted greater post-treatment belonging, gratitude, and purpose in life, though not social anxiety reduction. STE involving a sense of self-loss were infrequently endorsed and did not predict outcomes. Findings highlight the potential importance of connection-focused STE and emotions during MDMA-AT for promoting psychological flourishing and eudaimonic wellbeing, laying the groundwork for future larger-scale mechanistic trials.
