Previous studies have shown that self-efficacy influences cancer survivors' quality of life. As most of the relevant findings are based on Caucasian cancer survivors, whether the same relationship holds among Asian cancer patients and through what mechanism self-efficacy influences quality of life are unclear. This study examined the association between self-efficacy and quality of life among Chinese cancer survivors, and proposed affect (positive and negative) as a mediator between self-efficacy and quality of life. A sample of 238 Chinese cancer survivors (75% female, mean age = 55.7) were recruited from Beijing, China. Self-efficacy, affect (positive and negative) and quality of life were measured in a questionnaire package. Self-efficacy was positively associated with quality of life and positive affect, and negatively associated with negative affect. Path analyses revealed the direct effect from self-efficacy to quality of life and the indirect effects from self-efficacy to quality of life through positive affect and negative affect. The beneficial role of self-efficacy in Chinese cancer survivors' quality of life and the mediating role of affect in explaining the relationship between self-efficacy and quality of life are supported. Future interventions should include self-care and affect regulation skills training to enhance cancer survivors' self-efficacy and positive affect, as this could help to improve Chinese cancer survivors' quality of life.
以往研究表明，自我效能感会影响癌症幸存者的生活质量。由于大多数相关研究结果是基于白人癌症幸存者得出的，所以亚洲癌症患者中是否存在同样的关系，以及自我效能感通过何种机制影响生活质量尚不清楚。本研究调查了中国癌症幸存者的自我效能感与生活质量之间的关联，并提出情感（积极和消极）作为自我效能感与生活质量之间的中介变量。从中国北京招募了238名癌症幸存者作为样本（75%为女性，平均年龄 = 55.7岁）。通过一套问卷对自我效能感、情感（积极和消极）以及生活质量进行了测量。自我效能感与生活质量和积极情感呈正相关，与消极情感呈负相关。路径分析揭示了自我效能感对生活质量的直接效应，以及自我效能感通过积极情感和消极情感对生活质量的间接效应。自我效能感在中国癌症幸存者生活质量中的有益作用以及情感在解释自我效能感与生活质量关系中的中介作用得到了支持。未来的干预措施应包括自我护理和情感调节技能培训，以提高癌症幸存者的自我效能感和积极情感，因为这有助于改善中国癌症幸存者的生活质量。
