Perceived control, self-management efficacy, and quality of life in patients treated with radiation therapy for breast cancer: a longitudinal study.

OBJECTIVE: This longitudinal study aims to examine the present state of perceived control, self-management efficacy, and overall quality of life (QoL) in patients with breast cancer undergoing radiotherapy, and gain insight into the dynamic trends and factors that influence the quality of life experienced by patients during the course of radiotherapy. METHODS: Participants completed the Cancer Experience and Efficacy Scale (CEES), Strategies Used by People to Promote Health (SUPPH), and Functional Assessment of Cancer Therapy- Breast (FACT-B). The data was analyzed using the software SPSS26.0. Repeated measures analysis of variance (ANOVA) and mixed-effects linear models were used to analyze trends in perceived control, self-management efficacy, and QoL at three-time points, as well as factors affecting QoL during radiotherapy. RESULTS: Perceived control and self-management efficacy were associated with QoL over the course of the radiotherapy. Self-management efficacy (ß = 0.30, P < 0.001), presence of chemotherapy (ß = 18.33, P = 0.024), and duration of illness (ß = 2.25, P = 0.028) had a positive effect on the change in QoL, while time (ß = - 2.95, P < 0.001), cancer experience (ß = - 0.46, P < 0.001), and type of medical insurance (ß = - 2.77, P = 0.021) had the negative effect on the change in QoL. CONCLUSION: The QoL, perceived control, and self-efficacy of patients with breast cancer show dynamic changes during radiotherapy. The higher the self-efficacy, the better the QoL, and the worse the QoL when the sense of disease control is poor. At the same time, more attention should be paid to the QoL of breast cancer radiotherapy patients with a long course of the disease, receiving chemotherapy, and different medical payment methods.

Association between self-disclosure and benefit finding of Chinese cancer patients caregivers: the mediation effect of coping styles.

PURPOSE: To examine the relationship between self-disclosure, coping styles, and benefit finding (BF) among caregivers of cancer patients. The study also aimed to identify the factors influencing BF and the impact of coping styles on the relationship between self-disclosure and BF. METHODS: Convenience sampling was used to select 300 caregivers of cancer patients aged greater than 18 years from October 2022 to April 2023 in Chengdu, China. The demographic and clinical characteristics questionnaire, the Benefit Finding Scale (BFS), the Distress Disclosure Index Scale (DDI), and the Simple Coping Style Scale (SCSQ) for caregivers were included in this study. Descriptive statistics, t-tests, one-way analysis of variance, Pearson's correlation analyses, and multiple linear regression models were used. The effect of mediation was tested by the PROCESS macro (Model 4) for SPSS 26.0 by Hayes using 5000 bootstrap samples. RESULTS: There were 292 valid questionnaires (effective response rate 97.33%). The total scores of BF, self-disclosure, negative coping style, and positive coping style of caregivers were 67.77 ± 14.78, 38.23 ± 8.59, 19.68 ± 5.98, and 9.88 ± 4.18, respectively; Pearson's correlation analysis showed that BF was positively correlated with self-disclosure, positive coping, and negatively correlated with negative coping; multiple linear regression analysis showed that self-disclosure, positive coping, and negative coping were influential factors of BF. The results revealed that the effect of self-disclosure on BF was partly mediated by coping styles. It also confirmed that the mediation effect accounted for 54.03% of the total effect. CONCLUSION: The BF of caregivers is at a moderate level. Self-disclosure may influence BF partly because of coping styles.
