The Relationship Between Self-Confidence and Quality of Life in Women Undergoing Treatment for Breast Cancer

Jalileh Amirzehni



Introduction: Quality of life is an important topic in the study of chronic diseases, especially cancer. This disease also affects the patients’ self-confidence. This study was therefore conducted to determine the quality of life and its relationship with self-confidence in women undergoing treatment for breast cancer. Methods: This cross-sectional, descriptive, analytical study was conducted in 2016 on 166 women with breast cancer undergoing treatment at Ghazi, Al-Zahra, International and Shams hospitals in Tabriz. The subjects were selected through convenience sampling. A personal-demographic questionnaire, the Cancer Quality of Life Questionnaire (QLQ-C30) and the Rosenberg Self-Esteem Scale (RSES) were completed for each patient. The data obtained were analyzed using the independent t-test, the one-way ANOVA, the multivariate linear regression test and Pearson’s correlation coefficient. Findings: The mean total score of quality of life was 59.1±17.4, ranging from 0 to 100. The highest mean score was obtained in the cognitive subscale (74.9±23.8) and the lowest in the emotional subscale (51.4±21.1). The mean score of self-confidence was 0.3 with a standard deviation of 0.4, ranging from -1 to +1. There was a significant positive relationship between self-confidence and quality of life, except in three symptom subscales, including diarrhea, constipation and loss of appetite (P<0.05). The variables of self-confidence, disease duration, lifestyle, marital satisfaction and caregiver were among the predictors of quality of life. Discussion: Given the significant relationship between quality of life and self-confidence, health care providers may need to pay special attention to women undergoing treatment for breast cancer and perform timely measures to maintain their self-confidence and improve their quality of life.
