To assess the reliability and validity of the work-ability support scale (WSS) in a severe traumatic/acquired brain injury (TBI/ABI) population seeking to return to work (RTW).
One hundred forty-four clients were enrolled in a vocational rehabilitation (VR) intervention trial through the Brain Injury Rehabilitation Program in New South Wales, Australia. Each client's primary brain injury clinician and VR provider completed the WSS pre- and post-intervention. Validating measures assessing dysexecutive behavior, disability, participation, and work instability were completed. Several aspects of reliability and validity were evaluated.
Internal consistency was excellent for Part A (Cronbach's s > 0.9) but unacceptably low to questionable for Part B (s < 0.6). Inter-rater reliability between clinicians and VR providers was generally fair to moderate for Part A ( < 0.6) and worse for Part B ( < 0.5), with both slightly improving at post-intervention. Strong support was found for predictive and convergent validity, but not divergent validity. Confirmatory factor analysis indicated a poor fit for Part A, whereas most Part B fit indices met criteria.
The WSS can play a useful role in assessing return to work (RTW) potential, planning and evaluation after severe TBI/ABI. Training could improve consistency of administration among staff working across health and VR service sectors.
评估工作能力支持量表（WSS）在寻求重返工作（RTW）的严重创伤性/获得性脑损伤（TBI/ABI）人群中的可靠性和有效性。
通过澳大利亚新南威尔士州脑损伤康复计划，144 名患者入组一项职业康复（VR）干预试验。每位患者的主要脑损伤临床医生和 VR 提供者在干预前后均完成了 WSS 评估。还完成了评估执行功能障碍、残疾、参与度和工作稳定性的有效验证措施。评估了多个可靠性和有效性方面。
A 部分的内部一致性非常好（Cronbach's s > 0.9），但 B 部分的一致性差（s < 0.6），令人质疑。临床医生和 VR 提供者之间的评分者间信度对于 A 部分通常为一般到中度（<0.6），对于 B 部分更差（<0.5），且两者在干预后都略有提高。强烈支持预测性和收敛有效性，但不支持发散有效性。验证性因子分析表明 A 部分的拟合度较差，而 B 部分的大部分拟合指数均符合标准。
WSS 可在评估严重 TBI/ABI 后重返工作（RTW）的可能性、计划和评估方面发挥有用作用。培训可以提高跨卫生和 VR 服务部门工作的员工在管理方面的一致性。
