The Role of Illness Perception and Self-Efficacy in Determining Quality of Life among Cancer Patients

Abstract

Background: The quality of life for people with chronic illnesses like cancer has been shown to be significantly impacted by self-efficacy and perceptions of their illness. Objectives: This study investigates the relationship between cancer patients’ perceptions of their illness, their self-efficacy beliefs, and their quality of life. Method: Conducted from December 2022 to February 2023, this research involved 120 adults undergoing cancer treatment. We utilized the Illness Perception Questionnaire (IPQ), the Arabic version of the Cancer Behavioral Inventory Brief (CBI-B), and the Arabic EORTC QLQ-C30, alongside clinical data collection. Statistical analyses included Pearson correlation and descriptive statistics. Results: Breast cancer emerged as the most common type among participants. A positive correlation was found between self-efficacy and quality of life, as measured by the EORTC QLQ-C30, particularly in relation to symptom management. Interestingly, all dimensions of illness perception correlated with quality of life, except for control and concerns. Conclusions: The findings underscore the vital role of nurses and healthcare providers in aiding cancer patients to develop and utilize self-management strategies effectively. The study reveals that a patient’s capacity to manage their illness is significantly influenced by their confidence, understanding of their condition, and overall quality of life. Addressing these aspects can greatly enhance healthcare professionals’ contribution to improving the resilience and well-being of individuals battling cancer.
