Purpose: The purpose of this study was to identify the influence of depression, optimism and posttraumatic growth on health-related quality of life in female breast cancer survivors received adjuvant chemotherapy. Methods: In total, 115 female breast cancer survivors participated in this descriptive correlational study. The participants answered self-report questionnaires. Data were collected from 1 June 2020 to 10 June 2020, and were analyzed using descriptive statistics, the t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression with SPSS for Windows ver. 24.0. Results: The mean age of the breast cancer survivors was 45.83 years. The mean score for the degree of health-related quality of life was 81.85 out of 148 points. Participants' scores for health-related quality of life differed significantly based on economic status (F=5.36 p=.006) and hobbies (t=-3.37, p=.001). Health-related quality of life was negatively correlated with depression (r=-.73, p<.001), and positively correlated with optimism (r=.65, p<.001) and posttraumatic growth (r=.28, p=.002). Depression (𝛽=-.55, p<.001) was the most significant factor that affects health-related quality of life, followed by optimism (𝛽=.29, p<.001), and post-traumatic growth (𝛽=.12, p=.048), which together accounted for 62.2% (F=63.61, p<.001) of the variance. Conclusion: It is necessary to develop educational programs for breast cancer survivors to reduce depression, increase optimism and post-traumatic growth, and improve the health-related quality of life. By adapting these programs, positiveness may increase and this may lead to improvement of health-related quality of life for breast cancer survivors.
