Objective: This research investigated the mediating role of self-compassion in the relationship of type D personality with psychological well-being and self-care behaviors in patients suffering from type 2 diabetes. Research Method: The statistical population of this research included all patients with type 2 diabetes in the cities of Rasht and Rezvanshahr in 2020-2021. In this descriptive cross-sectional study, 368 patients were selected through purposive consecutive sampling. The participants completed the questionnaire of the summary of diabetes self-care activities (SDSCA), type D personality scale (DS-14), Ryff's scale of psychological well-being (RSPWB), and self-compassion scale – short form (SCS-SF). The data were processed through structural equation modeling (SEM) in AMOS-24. Bootstrapping was carried out by Preacher and Hayes’ (2008) macro to analyze the mediating relationships. Results: According to the bootstrapping analysis, self-compassion plays a significantly mediating role in the relationship of type D personality with psychological well-being and self-care behaviors (in all cases p<0.0001). The coefficient of determination of the final model demonstrated that all exogenous and medicating variables can predict 89% of the psychological well-being changes and 87% of self-care behaviors. Conclusions: Self-compassion can serve as a buffer and reduce the destructive effects of the type D personality on the psychological well-being and self-care behaviors in diabetic patients. Thus, taking measures to train and strengthen self-compassion is essential in the psychological treatment of diabetic patients.
