Self-Compassion: The Factor That Explains a Relationship between Perceived Social Support and Emotional Self-Regulation in Psychological Well-Being of Breast Cancer Survivors

Objective: Perceived social support (PSS) and emotional self-regulation have customarily been related to greater psychological well-being, but the pathways via which perceived social support and emotional self-regulation increase psychological well-being have not been revealed. We investigated how much self-compassion mediated the association between perceived social support and emotional self-regulation in psychological well-being of breast cancer sufferers. Method : A cross-sectional study design was used. Participants were recruited from three oncology departments in Zanjan, Iran. Data was collected from breast cancer patients (n = 300). Participants completed self-report measures, the short Ryff scale Psychological Well-being (RSPWB), Emotion Regulation Questionnaire (ERQ), Multidimensional Scale of Perceived Social Support (MSPSS) and Self-Compassion Scale (SCS). Pearson correlation coefficient was used to assess association among the study variables and multivariable regression analysis was used to assess linear relationships among predictor variables (emotional self-regulation, perceived social support and self-compassion) and criterion variable (psychological well-being). Bootstrapping analyses were used to test the significance on indirect effects. Results: Bootstrapping analyses revealed significant indirect effects of perceived social support (β = 0.055, SE = 0.45, P = 0.049, 0.95 CI: LL = 0.0092, UL = 0.1345) and emotional self-regulation (β = 0.079, SE = 0.079, P = 0.004, 0.95 CI: LL = -0.0331, UL = -0.1358) on psychological well-being through self-compassion. Conclusion: These findings present new evidence that self-compassion may be a target for psychological interventions attempted at enhancing psychological well-being in cancer populations, particularly breast cancer survivors.
