Meditation use in the United States is about as common as accessing mental health services, making it important to understand its potential harms. In a survey of 886 U.S. adults, nearly all (96.6%) reported an unusual experience related to meditation, 58.4% reported an adverse effect on a standard inventory, 78.3% endorsed at least one item on a scale of meditation-related adverse effects, 31.4% said they had a challenging, difficult, or distressing experience, and 9.1% reported functional impairment due to such effects. Psychological distress, psychoticism, unusual beliefs, and attending a meditation retreat were each linked to more unusual experiences and adverse effects. The authors recommend informing potential meditators about possible experiences, considering risk factors, and routinely monitoring for adverse effects.

A new questionnaire, the Inventory of Meditation Experiences (IME), captures a wide range of meditation-related experiences, from pleasant to unpleasant and mild to intense. Developed with data from 886 US meditators, the final 30-item scale has three factors and shows good statistical fit. The IME correlates as expected with measures of adverse effects, meditation habits, and mental health symptoms. The tool allows researchers to assess both the intensity and subjective valence of experiences separately or together, offering a more nuanced way to study the full spectrum of meditation-related psychological states.

Meditation use is now as common as mental health service access. In a cross-sectional, population-based survey of 886 US adults, 96.6% reported an unusual experience related to meditation, 58.4% reported an adverse effect (AE), 78.3% endorsed at least one item on the Meditation-related AEs Scale, 31.4% reported a challenging, difficult, or distressing experience, and 9.1% reported functional impairment due to AEs. Psychological distress, psychoticism, unusual beliefs, and meditation retreat participation were positively associated with unusual experiences and AEs. The findings suggest that potential meditators should be informed about possible experiences, providers should consider risk factors, and AEs should be routinely and actively monitored.
