The Relationship Between Self-efficacy and Coping Mechanisms with Quality of Life in Breast Cancer Patients

Abstract

The exponential increase in incidence and mortality from breast cancer is of global concern. Breast cancer patients experience physical, psychological, social, and economic changes that reduce their quality of life. Several factors, such as self-efficacy and coping mechanisms, can affect the quality of life of breast cancer patients. This study aims to explain how self-efficacy and coping mechanisms affect the quality of life of breast cancer patients. This research is a correlational study with a cross sectional design. A sample of 320 respondents used total sampling as a sampling method. This tool measures the quality of life using the EORTC QLQ-C30, self-efficacy with the breast cancer survivor self-efficiency scale questionnaire, and coping mechanisms with the cancer management questionnaire (CCQ). The statistical analysis was based on multiple linear regression. The results showed that self-efficacy had a significant effect on quality of life (p = 0.000), coping mechanisms had a significant effect on quality of life (p = 0.000), and the joint effect of self-efficacy and coping mechanisms. For the quality of life of breast cancer patients (p-value 0.000). Self-efficacy and coping mechanisms have a partial or simultaneous positive impact on the quality of life of breast cancer patients. Therefore, follow-up interventions to improve self-efficacy and coping mechanisms in breast cancer patients are urgently needed.
