OBJECTIVE
To explore the mediating roles of depression and self-efficacy in the relationship between social support and body image in patients with breast cancer during chemotherapy.
METHODS
A convenience sampling method was employed to survey 647 breast cancer chemotherapy patients. The survey included validated scales assessing social support, depression, self-efficacy, and body image. The chain mediation model was established using Mplus 8.3 software.
RESULTS
Social support was negatively correlated with depression ( < 0.001) and poor body image ( < 0.001) and positively correlated with self-efficacy ( < 0.001). Social support indirectly affected body image through three mediating pathways: depression ( = -0.084, < 0.001), self-efficacy ( = -0.060, < 0.01), and the depression-self-efficacy pathway ( = -0.058, < 0.001). The indirect effect accounted for 55.96% of the total effect.
CONCLUSIONS
The results support our hypothesis. Enhancing social support, alleviating depression, and improving self-efficacy through psychological interventions are recommended to improve body image in breast cancer patients during chemotherapy.
目的
探讨抑郁和自我效能感在乳腺癌化疗患者社会支持与身体意象关系中的中介作用。
方法
采用便利抽样法对647例乳腺癌化疗患者进行调查。该调查包括评估社会支持、抑郁、自我效能感和身体意象的有效量表。使用Mplus 8.3软件建立链式中介模型。
结果
社会支持与抑郁（<0.001）和不良身体意象（<0.001）呈负相关，与自我效能感（<0.001）呈正相关。社会支持通过三条中介途径间接影响身体意象：抑郁（=-0.084，<0.001）、自我效能感（=-0.060，<0.01）以及抑郁-自我效能感途径（=-0.058，<0.001）。间接效应占总效应的55.96%。
结论
结果支持我们的假设。建议通过心理干预增强社会支持、减轻抑郁并提高自我效能感，以改善乳腺癌化疗患者的身体意象。
