摘要

目的探讨抑郁和自我效能在化疗期间乳腺癌患者的社会支持与身体形象之间的中介作用。方法采用便利抽样法对 647 名乳腺癌化疗患者进行调查。调查包括评估社会支持、抑郁、自我效能感和身体形象的有效量表。结果社会支持与抑郁（P <0.001）和不良身体形象（P <0.001）呈负相关，与自我效能（P <0.001）呈正相关。社会支持通过三个中介途径间接影响身体形象：抑郁（β = -0.084，P < 0.001）、自我效能（β = -0.060，P < 0.01）和抑郁-自我效能途径（β = -0.058，P < 0.001）。间接效应占总效应的 55.96%。建议通过心理干预加强社会支持、缓解抑郁和提高自我效能来改善化疗期间乳腺癌患者的身体形象。

Impact of social support on body image during chemotherapy in patients with breast cancer: The chain mediating role of depression and self-efficacy

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 (P < 0.001) and poor body image (P < 0.001) and positively correlated with self-efficacy (P < 0.001). Social support indirectly affected body image through three mediating pathways: depression (β = −0.084, P < 0.001), self-efficacy (β = −0.060, P < 0.01), and the depression-self-efficacy pathway (β = −0.058, P < 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.
