Purpose To translate and cross-culturally adapt the Work-Ability Support Scale (WSS) into Chinese and evaluate the reliability and validity of the measure among young and middle-aged stroke survivors. Methods A total of 210 participants aged 28-60 years were recruited from two communities in Zhengzhou. Item analysis, internal consistency, inter-rater reliability, and construct validity were tested. Results A moderate level of correlation between the items and the domains (r > 0.60), and the significant differences in items between the high group and the low group were tested by independent sample t-tests (P < 0.001). For Part A, Cronbach's α of the domains "physical", "thinking and communication", and "social/behavioural" was 0.865, 0.857 and 0.912, respectively. The Cronbach's α coefficient of Part A of the WSS was calculated as 0.931. The Cronbach's α of Part B was 0.761, with Cronbach's α values of 0.795, 0.649 and 0.643 for "personal factors", "environmental factors (within the workplace)", and "barriers to return to work", respectively. The split-half coefficients of Parts A and B were assessed as 0.804 and 0.559, respectively. The kappa coefficient of the other items all exceeded 0.60 (P < 0.001), except for a few items. The scale-level content validity index (S-CVI) was 0.94 and 0.90 for Parts A and B, respectively. The original construct of the scale was examined by confirmatory factor analysis (CFA), and model fit indices were mostly satisfactory. Conclusion The WSS is a reliable and valid tool for measuring young and middle-aged Chinese stroke survivors' work ability and support needs during their return to work.
目的 将工作能力支持量表（WSS）翻译并跨文化适应为中文，并评估该测量工具在中青年脑卒中幸存者中的信度和效度。
方法 共招募了来自郑州两个社区的 210 名 28-60 岁的参与者。对项目进行了分析、内部一致性、评定者间信度和结构效度的检验。
结果 项目与领域之间存在中等程度的相关性（r>0.60），通过独立样本 t 检验，高分组和低分组之间的项目差异具有统计学意义（P<0.001）。对于 A 部分，“身体”、“思维和沟通”和“社会/行为”领域的克朗巴赫α系数分别为 0.865、0.857 和 0.912。WSS A 部分的克朗巴赫α系数为 0.931。B 部分的克朗巴赫α系数为 0.761，其中“个人因素”、“工作场所内的环境因素”和“重返工作障碍”的克朗巴赫α值分别为 0.795、0.649 和 0.643。A 部分和 B 部分的两半系数分别为 0.804 和 0.559。除了少数项目外，其他项目的kappa 系数均超过 0.60（P<0.001）。量表水平的内容效度指数（S-CVI）分别为 A 部分和 B 部分的 0.94 和 0.90。通过验证性因子分析（CFA）检验了量表的原始结构，模型拟合指数大多令人满意。
结论 WSS 是一种可靠且有效的工具，可用于测量中青年脑卒中幸存者在重返工作时的工作能力和支持需求。
