The diagnosis of breast cancer and the subsequent treatment undermine patients' participation in social activities. This study aimed to carry out a cross-cultural adaption and analysis of the construct validity and reliability of the Chinese version of the PROMIS social function short forms in patients with breast cancer.
This study utilized a cross-sectional research design, and was registered in the Chinese Clinical Trial Registry (ChiCTR2000035439). After a standardized cross-cultural adaption process, a psychometric evaluation was performed of the Chinese version of the PROMIS social function short forms. Using convenience sampling, eligible patients with breast cancer from tertiary hospitals in China were enrolled from January 2019 to July 2020. Participants completed the sociodemographic information questionnaire, the PROMIS social function short forms, the Functional Assessment of Cancer Therapy-Breast, the PROMIS emotional support short form and the PROMIS anxiety short form.
Data were collected from a sample of 633 patients whose mean age was 48.1 years. The measures showed an absence of floor and ceiling effects. Regarding construct validity, the results of confirmatory factor analysis supported the original two-factor structure of the PROMIS social function short forms. In addition, the measures were found to have acceptable known-group validity, measurement invariance, and convergent and discriminate validity. Regarding reliability, the Cronbach's α was high for all items (> 0.70).
The Chinese version of the PROMIS social function short forms was demonstrated to be a valid and reliable measure for the assessment of social function in Chinese patients with breast cancer. Additional psychometric evaluation is needed to draw firm conclusions.
乳腺癌的诊断和随后的治疗会削弱患者参与社会活动的能力。本研究旨在对乳腺癌患者 PROMIS 社会功能简短形式的中文版本进行跨文化调适，并分析其结构效度和信度。
本研究采用横断面研究设计，在中国临床试验注册中心（ChiCTR2000035439）注册。经过标准化的跨文化调适过程，对 PROMIS 社会功能简短形式的中文版本进行了心理测量评估。采用便利抽样法，从 2019 年 1 月至 2020 年 7 月，从中国三级医院招募符合条件的乳腺癌患者。参与者完成了社会人口统计学信息问卷、PROMIS 社会功能简短形式、癌症治疗功能评估-乳房、PROMIS 情感支持简短形式和 PROMIS 焦虑简短形式。
共收集了 633 名平均年龄为 48.1 岁的患者的数据。这些测量方法没有出现地板效应和天花板效应。关于结构效度，验证性因子分析的结果支持 PROMIS 社会功能简短形式的原始两因素结构。此外，这些测量方法具有可接受的已知组有效性、测量不变性、以及收敛性和区分效度。关于可靠性，所有项目的克朗巴赫 α 值都很高（>0.70）。
PROMIS 社会功能简短形式的中文版本被证明是一种有效且可靠的评估中国乳腺癌患者社会功能的工具。需要进一步的心理测量评估来得出更确定的结论。
