Self-efficacy is a significant predictor of return to work and affects the confidence of survivors to return to work after illness. The Return-to-work self-efficacy (RTW-SE) questionnaire is a self-report questionnaire to assess confidence in returning to work with good reliability and validity. The aim of this study was to translate and cross-culturally adapt the RTW-SE questionnaire into Chinese and examine the psychometric properties among young and middle-aged stroke survivors using Rasch model analysis.
The cross-cultural adaptation and translation procedures followed a dual-translation approach. The psychometric properties of the RTW-SE questionnaire were examined using Rasch model analysis by Winsteps software. The unidimensionality and local independence were analyzed by principal component analysis of the residuals (PCAR) and standardized residual correlations.Category diagnostics were performed for scale function, and the item fit, reliability, and separation were also validated. Item-person maps were used to examine the distribution and matching of item's location and person ability. Finally, the differential item functioning (DIF) was used to measure gender-related group equivalence.
A total of 366 participants aged 23-59 years were recruited from three communities in Zhengzhou. The RTW-SE questionnaire demonstrated unidimensionality and a 5-point Likert rating scale was more appropriate to investigate young and middle-aged stroke survivors'self-efficacy. There was a good fit for the items with both person and item reliabilities greater than 0.8 and separation indices of 3.75 and 3.94, respectively. The item location was identified from the item-person map as not covering person ability, but the scale did not have an age-related DIF.
The results confirm evidence of appropriate psychometric properties of the RTW-SE questionnaire and can be used as a reliable and validated instrument for measuring self-efficacy to return to work in young and middle-aged Chinese patients with stroke.
自我效能感是预测重返工作岗位的重要指标，它影响着患者在患病后重返工作岗位的信心。重返工作自我效能感（RTW-SE）问卷是一种自我报告问卷，用于评估重返工作的信心，具有良好的信度和效度。本研究旨在将 RTW-SE 问卷翻译成中文，并使用 Rasch 模型分析检验其在中青年脑卒中幸存者中的心理测量特性。
采用双翻译法进行跨文化适应性翻译。使用 Winsteps 软件的 Rasch 模型分析检验 RTW-SE 问卷的心理测量特性。通过残差主成分分析（PCAR）和标准化残差相关分析进行单维性和局部独立性分析。对量表功能进行类别诊断，验证项目拟合、信度和分离度。使用项目-人映射图检查项目位置和人员能力的分布和匹配。最后，使用差异项目功能（DIF）测量性别相关组等效性。
共招募了来自郑州三个社区的 366 名 23-59 岁的参与者。RTW-SE 问卷表现出单一维度，5 点 Likert 评分更适合调查中青年脑卒中幸存者的自我效能感。项目和人员的拟合度良好，可靠性均大于 0.8，分离指数分别为 3.75 和 3.94。从项目-人映射图中可以看出，项目位置并未涵盖人员能力，但量表没有年龄相关的 DIF。
结果证实了 RTW-SE 问卷具有适当的心理测量特性，可以作为测量中青年脑卒中患者重返工作岗位自我效能的可靠和有效的工具。
