Abstract
Objective: To investigate meditation-related psychological adverse effects, challenging, unpleasant, and negative experiences (MRPAEs) across meditative development and specifically advanced meditation, an emerging domain in contemplative science that remains understudied despite its potential for radically positively transforming, and in some cases destabilizing, mental health.
Design: A qualitative study using semi-structured phenomenological interviews and inductive, content-driven thematic analysis. Theoretical saturation was monitored iteratively, interrater reliability was assessed throughout the coding process, and methodological reporting adhered to the Consolidated Criteria for Reporting Qualitative Research (COREQ).
Participants: 28 advanced meditators with extensive long-term practice histories who were proficient in advanced practices.
Setting: Remote, in-depth interviews conducted with advanced meditators with diverse contemplative backgrounds.
Results: Across 55 interviews, participants described wide-ranging negative and appraisal-dependent experiences spanning affective, cognitive, relational, clinical, and existential domains. Seven major themes were identified: (1) broadly negative cognitive, attentional, and existential disruptions; (2) negative affect, including mood disturbance, anxiety, and fear; (3) adverse impacts on life trajectory and interpersonal relationships; (4) negative clinical and non-clinical transformative experiences, including clinically significant psychiatric symptoms and trauma activation; (5) foundational instability associated with specific meditative insights; (6) ambiguous experiences of context-dependent valence; and (7) resolution strategies, including meditative techniques, teacher guidance, and interpersonal support.
Conclusions: Advanced meditation can precipitate significant psychological challenges across multiple domains. Although meditative development is also associated with profound positive transformation, these findings highlight the importance of distinguishing productive challenge from genuine harm, and provide initial empirical evidence that meditative development warrants dedicated clinical frameworks and interdisciplinary support structures.
