Abstract
Self-esteem is a way of coping with stress for cancer patients and this improves their quality of life. It was aimed to determine the relationship between type A personality traits and self-esteem and quality of life in women with breast cancer and to determine the effective factors. 154 women with breast cancer and 78 healthy women were included. Bortner's Rating scale, Rosenberg's Self-Esteem scale, and EORTC QOL-C30 scale were used. The relationship between the presence of hobbies, self-esteem, quality of life, and personality type was examined. Mann-Whitney U, Kruskal-Wallis, Fisher's Exact, and Spearman Rank correlation tests were performed. Independent factors affecting personality type, self-esteem, and quality of life were determined by multivariate logistic (binary) regression analysis. The p < 0.05 value was significant in the SPSS v19 program. There was no age difference between the patients (54 ± 11 years) and the control group (42 ± 8 years) (p = 0.108). The rate of type A personality was 69% in patients and 58% in controls (p = 0.093). Similarly, the rate of high self-esteem was 93% in patients and 96% in controls (p = 0.098). Besides personality type and self-esteem, there was no relationship between personality type and quality of life in cancer patients (p = 0.960 and p = 0.946, respectively). A relationship was established between self-esteem and quality of life (p = 0.018) in patients. In patients with type A personality, hobbies providing socially active communication were common (p = 0.039), and had more than two hobbies (p = 0.015). Type A personality trait was independently effective on self-esteem (p = 0.046). Hobby orientation and the number of hobbies had independent effects on self-esteem (p = 0.032, p = 0.041), quality of life (respectively, p = 0.004, p = 0.007), and personality type (respectively, p = 0.014, p = 0.027). Hobbies that provide active social communication may have important effects on changes in personality traits, self-esteem, and quality of life in patients with breast cancer.
