The Mediating Role of Perceived Social Support in the Effect of the CALM Intervention on Quality of Life in Patients Following Breast Cancer Surgery

Abstract

Abstract Objective Despite numerous studies demonstrating the positive effects of psychological interventions on psychological resilience and quality of life in postoperative breast cancer patients, the specific contribution of perceived social support to these outcomes remains uncertain. This study aimed to investigate the impact of the Managing Cancer and Living Meaningfully (CALM) intervention on these outcomes and explore the potential mediating role of perceived social support. Methods A total of 124 adult breast cancer patients were randomly assigned to the intervention group (IG, n = 62) or the control group (CG, n = 62). Baseline and three follow-up assessments were conducted to measure psychological resilience, quality of life, anxiety, depression, and perceived social support. Data were analyzed using mixed linear models and structural equation modeling. Results A total of 124 adult breast cancer patients were randomly assigned to the intervention group (IG, n = 62) or the control group (CG, n = 62). Baseline and three follow-up assessments were conducted to measure psychological resilience, quality of life, anxiety, depression, and perceived social support. Data were analyzed using mixed linear models and structural equation modeling. Conclusions The CALM intervention enhanced psychological resilience, quality of life, and perceived social support among postoperative breast cancer patients. The mediating role of perceived social support emphasizes its significance in promoting well-being. Integrating interventions such as CALM into standard care can contribute to overall well-being and satisfaction in post-mastectomy patients.
