The mediating role of resilience and self-efficacy in the relationship between perceived social support and psychological distress in breast cancer patients
Abstract
Background and Aim: Breast cancer is the most common cancer among women, often leading to emotional challenges. This study aimed at investigating the mediating roles of resilience and self-efficacy in the relationship between perceived social support and psychological distress among breast cancer patients. Methods: This cross-sectional study was conducted on women with breast cancer admitted to Imam Khomeini and Imam Hossein Hospitals in Tehran, Iran, in 2023. A total of 250 patients were included using convenience sampling. Data were collected using the Depression, Anxiety, and Stress Scales (DASS) by Lovibond (1995), Resilience Scale (RISC) by Connor and Davidson (2003), General Self-Efficacy Scale (GSES) by Scherer et al. (1982), and Multidimensional Scale of Perceived Social Support (MSPSS) by Zimet et al. (1988). Results: Perceived social support had a direct and significant effect on resilience (β=0.34, P=0.001) and self-efficacy (β=0.19, P=0.019) in women with breast cancer. However, no significant direct relationship was found between perceived social support and psychological distress. Resilience (β=-0.46, P=0.001) and self-efficacy (β=0.33, P=0.001) directly influenced psychological distress, with both factors mediating the relationship between social support and distress. The final model demonstrated good fit indices (CFI=0.93, CMIN/DF=1.82, RMSEA=0.064, P<0.05) and explained 34% of psychological distress variance. Conclusion: Considering the mediating roles of resilience and self-efficacy, implementing educational-therapeutic interventions focused on enhancing self-efficacy and resilience could effectively alleviate psychological distress in women with breast cancer.
