The Dutch 30-item Revised Mystical Experience Questionnaire (MEQ30) is a reliable and valid tool for assessing mystical experiences induced by psychedelics. In an online survey of 322 Dutch-speaking adults who retrospectively reported profound psychedelic experiences, confirmatory factor analyses supported both a four-factor structure and a model with a total score as a second-order latent variable. Factor scores showed good internal reliability (alpha between .81 and .94) and were higher among participants who reported having had a mystical experience, supporting construct validity. MEQ30 scores also predicted meaningfulness, spiritual significance, and positive changes in well-being, life satisfaction, and behavior, offering preliminary evidence of predictive validity.
