Self-efficacy is a crucial variable that is related to quality of life. Patients who have high self-efficacy will exert sufficient effort and have better health outcomes and improved quality of life. Appropriate and precise measurement of self-efficacy can help promote better care. The Breast Cancer Survivor Self-efficacy Scale (BCSES) is designed to measure the perceived confidence of breast cancer patients in managing the tasks for self-management. Originally developed in America, it has not been used in China.
The aims of this study were to translate BCSES into Chinese and assess its psychometric properties among Chinese patients.
In phase 1, the translation of BCSES closely followed the Principles of Good Practices. In phase 2, data on reliability and validity were evaluated in terms of internal consistency, item-total correlations, test-retest reliability, criterion validity, and construct validity. A total sample of 630 native Chinese-speaking patients from 5 hospitals in China participated, including a pilot sample of 182 and a validation sample of 448.
Minor modifications in 5 items were recommended after translation. Both exploratory and confirmatory factor analyses suggested a 2-factor structure was more ideal than the original 1-factor model. Cronbach's α coefficient for the Chinese version of BCSES was .82, intraclass correlation coefficient was 0.97, and item-total correlations were from 0.61 to 0.76.
The Chinese version of BCSES appears to be culturally appropriate, reliable, and valid for assessing self-efficacy among patients with breast cancer in China.
The Chinese version of BCSES could help measure the breast cancer patients' self-efficacy and provide evidence to develop culturally sensitive interventions for Chinese patients.
自我效能感是与生活质量密切相关的关键变量。自我效能感高的患者会付出足够的努力，获得更好的健康结果和更高的生活质量。对自我效能感进行适当和准确的测量有助于促进更好的护理。乳腺癌幸存者自我效能感量表（BCSES）旨在衡量乳腺癌患者管理自我管理任务的感知信心。该量表最初在美国开发，尚未在中国使用。
本研究旨在将 BCSES 翻译成中文，并评估其在中国患者中的心理测量特性。
在第 1 阶段，BCSES 的翻译紧密遵循良好实践原则。在第 2 阶段，从内部一致性、条目总分相关性、重测信度、效标效度和结构效度等方面评估了信度和效度。共有来自中国 5 家医院的 630 名母语为中文的患者参与了研究，包括 182 名预试样本和 448 名验证样本。
翻译后建议对 5 个项目进行小的修改。探索性和验证性因子分析均表明，双因素结构比原始的单因素模型更理想。BCSES 中文版的克朗巴赫 α 系数为.82，组内相关系数为 0.97，条目总分相关性为 0.61 至 0.76。
BCSES 中文版在中国乳腺癌患者中具有文化适宜性、可靠性和有效性，可用于评估自我效能感。
BCSES 中文版可帮助测量乳腺癌患者的自我效能感，并为制定针对中国患者的文化敏感性干预措施提供证据。
