Nonattachment mediates the associations between mindfulness, well-being, and psychological distress: A meta-analytic structural equation modeling approach.

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.
