Engaging in meditation on a regular basis has been shown to enhance well-being. However, barriers to adopting it as a health behavior are poorly understood. The Determinants of Meditation Practice Inventory (DMPI) is an existing scale designed to measure perceived barriers to meditation. However, it was developed without factor analyses; thus, the dimensionality and construct validity of overall scale and/or subscale scores are unknown. Using factor analyses and tests of convergent validity, the present study explored the psychometric properties of the DMPI and presents a revised, psychometrically valid scale (The Determinants of Meditation Practice Inventory-Revised; DMPI-R).
Adult participants living in the USA ( = 621) provided data through an online survey platform. Extensive exploratory factor analyses were conducted ( = 311) and followed by confirmatory factor analysis ( = 310) on the best-fitting model. Convergent validity was estimated using the full sample data.
Five items were removed because they demonstrated high residual variances and cross loaded onto multiple factors. Relationships among the remaining items were best explained by a four-factor structure with the following subscales: low perceived benefit, perceived inadequate knowledge, perceived pragmatic barriers, and perceived sociocultural conflict. Convergent validity was evidenced by associations between subscale scores and experiential avoidance, distress tolerance, and curiosity.
The multifactor structure of the DMPI-R indicates that there are multiple classes of perceived barriers on which people can vary. Validity analyses suggest that the DMPI-R is a promising measure of perceived barriers to meditation among North American adults.
有研究表明,定期进行冥想能提升幸福感。然而,对于将冥想作为一种健康行为所面临的障碍,我们了解得还很少。冥想练习决定因素量表(DMPI)是一个现有的量表,旨在测量感知到的冥想障碍。然而,该量表的开发未经过因素分析;因此,整个量表和/或子量表分数的维度及结构效度尚不清楚。本研究通过因素分析和收敛效度检验,探讨了DMPI的心理测量特性,并提出了一个经过修订的、具有心理测量效度的量表(冥想练习决定因素量表修订版;DMPI-R)。
居住在美国的成年参与者(n = 621)通过在线调查平台提供数据。对311名参与者进行了广泛的探索性因素分析,随后对拟合度最佳的模型对310名参与者进行了验证性因素分析。使用全样本数据估计收敛效度。
剔除了5个项目,因为它们显示出高残差方差并在多个因素上交叉载荷。其余项目之间的关系最好由一个四因素结构来解释,该结构具有以下子量表:低感知益处、感知知识不足、感知实用障碍和感知社会文化冲突。子量表分数与经验回避、痛苦耐受性和好奇心之间的关联证明了收敛效度。
DMPI-R的多因素结构表明,人们在感知到障碍的多个类别上存在差异。效度分析表明,DMPI-R是衡量北美成年人感知到的冥想障碍的一个有前景的量表。
