Abstract：
In the Netherlands, scientific interest in psychedelics and their subjective effects has been increasing. The present study examined the reliability, construct and predictive validity of the Dutch 30-item Revised Mystical Experience Questionnaire (MEQ30), a self-report measure that has been used to assess subjective and mystical experiences occasioned by psychedelics. In an online survey, 322 Dutch-speaking adults retrospectively reported on profound experiences with psychedelics. Confirmatory factor analyses demonstrated that both a four-factor structure and the same model extended with the MEQ30-total score as a second-order latent variable fit the data. Factor scores showed good internal reliability (α = between .81 and .94) and were significantly higher in participants that beforehand endorsed having had a mystical experience compared to those that did not, providing evidence for the construct validity of the questionnaire as a measure for self-reported mystical experiences. Additionally, MEQ30 scores significantly predicted the meaningfulness and spiritual significance of the psychedelic experience, as well as self-reported positive changes in well-being, life satisfaction and behavior, providing preliminary evidence for the predictive validity of the Dutch MEQ30. Findings suggest the reliability and validity of the Dutch MEQ30 and support the use of the scale in future studies on the subjective effects of psychedelics.
摘要：
在荷兰,对迷幻药及其主观效果的科学兴趣一直在增加。本研究检查了可靠性，荷兰30项修订的神秘体验问卷(MEQ30)的构建和预测效度，一种自我报告的方法，用于评估迷幻药引起的主观和神秘经历。在一项在线调查中,322名讲荷兰语的成年人回顾性报道了迷幻药的深刻经历。验证性因素分析表明，四因素结构和以MEQ30总分作为二阶潜在变量扩展的相同模型都可以拟合数据。因子得分显示出良好的内部可靠性（α=0.81和0.94之间），并且在事先认可有神秘经历的参与者中，与没有神秘经历的参与者相比，因子得分明显更高，为问卷的结构效度提供证据，以衡量自我报告的神秘经历。此外,MEQ30得分显着预测了迷幻体验的意义和精神意义，以及自我报告的幸福感的积极变化，生活满意度和行为，为荷兰MEQ30的预测有效性提供初步证据。研究结果表明荷兰MEQ30的信度和效度，并支持在未来有关迷幻药主观影响的研究中使用该量表。
