Research on nonattachment, a Buddhist psychological construct closely related to mindfulness, has burgeoned since the development of the Nonattachment Scale. The aim of the current meta-analysis was to investigate the mediating role of nonattachment in the relationship between mindfulness and well-being and psychological distress using a meta-analytic structural equation modeling approach. The respective associations of nonattachment and mindfulness with well-being and psychological distress, after controlling for each other, were also examined. Forty-one independent cross-sectional data sets with 24,704 individuals were coded. Results showed that nonattachment partially mediated the associations between mindfulness and well-being and psychological distress. Nonattachment and mindfulness were both significantly positively associated with well-being and negatively associated with psychological distress after controlling for each other. Given the present findings were based on cross-sectional data, more studies with rigorous research design, such as longitudinal, experimental, and intervention studies, should be conducted to further investigate the mediating effect of nonattachment between mindfulness with well-being and distress outcomes and establish causal relations between them. Future research directions regarding nonattachment and its application in mindfulness-based interventions were discussed.

不执着研究，一种与正念密切相关的佛教心理结构，自非依恋量表的发展以来迅速发展。当前荟萃分析的目的是使用荟萃分析结构方程建模方法研究不依恋在正念与幸福和心理困扰之间的关系中的中介作用。在相互控制之后，还检查了不依恋和正念与幸福和心理困扰的各自关联。对 24,704 个人的 41 个独立横截面数据集进行了编码。结果表明，不依恋部分地介导了正念与幸福感和心理困扰之间的关联。不依恋和正念都与幸福感显着正相关，在相互控制后与心理困扰呈负相关。鉴于目前的研究结果是基于横断面数据，应该进行更多具有严格研究设计的研究，例如纵向、实验和干预研究，以进一步研究不依附在正念与幸福和痛苦结果之间的中介作用，以及建立它们之间的因果关系。讨论了关于非依恋及其在基于正念的干预中的应用的未来研究方向。
