Meditation-Related Adverse Effects: Toward an Interactional Model of Disposition, Practice, and Context

Meditation and mindfulness practices now reach clinical, educational, organizational, and digital settings, and a growing literature documents difficult, distressing, and occasionally impairing experiences associated with them. Their existence is no longer seriously disputable; their prevalence, causal attribution, and determinants remain unsettled. This critical integrative review examines phenomenological studies, surveys of meditators, population-based and representative samples, systematic reviews, program and trial-based studies, and prospective experience-sampling and matched-controlled retreat studies. Reported rates vary with sampling, definition, ascertainment, timescale, and severity threshold; most designs cannot establish temporal order or exclude confounding; and the few prospective controlled studies find no excess deterioration in the structured formats examined. Two conceptual clarifications are proposed. First, outcomes are located on independent axes of severity (unusual experience, unpleasant experience, adverse experience, functional impairment, lasting harm) and attribution. Second, the causal role of practice (direct cause, contributing cause including trigger and amplifier, or coincidence) is distinguished from the locus of causation (technique, dose, setting, guidance, or appraisal). The paper then develops an interactional model in which outcomes emerge from configurations of six domains: antecedent state and disposition, practice type, dose and intensity, environment, guidance and relationships, and appraisal and integration, unfolding along an experiential trajectory. Retreat participation is reconceived as a decomposable ecology rather than a dose. Evidence grades are assigned to each domain; eight falsifiable propositions, a prespecified interaction structure, and a minimum reporting set are derived; and practice recommendations, including for unguided digital practice, are tied to specific propositions.
