Purpose: This study examined relationships between coping styles and quality of life (QoL) in oncology patients undergoing radiotherapy compared with healthy controls. Coping styles and QoL were assessed to elucidate connections and inform psychosocial care. Methods: 57 females participated, including 28 breast cancer patients undergoing radiotherapy and 29 healthy controls matched on demographics. Participants completed the COPE Inventory, which measures active, emotion-focused, and avoidant coping levels, and the SF-36, which assesses mental, physical, and overall QoL. Between-group differences were analyzed using the Mann–Whitney U test. Correlations between coping styles and QoL were examined with Spearman’s r. Results: Breast cancer patients showed a significantly lower QoL on all scales versus controls. In patients, active coping weakly correlated with physical QoL, while avoidance moderately to strongly correlated with poorer mental, physical, and overall QoL. In controls, active coping strongly correlated with mental and overall QoL, and avoidance moderately negatively correlated across domains. Conclusion: Maladaptive avoidance coping was strongly related to poorer QoL in both groups, especially patients. Active coping showed limited benefits for patients’ QoL, in contrast with the controls. Those with low scores require effective interventions during radiotherapy, which are crucial for coping with treatment adverse effects.
目的：本研究探讨接受放射治疗的肿瘤患者与健康对照者在应对方式与生活质量（QoL）之间的关系，通过评估应对方式与生活质量以阐明其关联并为心理社会护理提供依据。方法：57名女性参与研究，包括28名接受放射治疗的乳腺癌患者和29名人口统计学特征匹配的健康对照者。参与者完成COPE量表（测量主动应对、情绪聚焦应对及回避应对水平）和SF-36量表（评估心理、生理及整体生活质量）。采用曼-惠特尼U检验分析组间差异，通过斯皮尔曼相关系数检验应对方式与生活质量的相关性。结果：乳腺癌患者在各项生活质量指标上均显著低于对照组。在患者组中，主动应对与生理生活质量呈弱相关，而回避应对与较差的心理、生理及整体生活质量呈中度至强相关。在对照组中，主动应对与心理及整体生活质量呈强相关，回避应对在各领域均呈中度负相关。结论：适应不良的回避应对与两组（尤其是患者组）较差的生活质量密切相关。与对照组相比，主动应对对患者生活质量的改善作用有限。在放射治疗期间，应对方式得分较低的个体需要有效干预措施，这对应对治疗不良反应至关重要。
