To further improve measurement of work-related physical and mental health by updating the Work Disability Assessment Battery (WD-FAB).
Cross-sectional study with 1024 disability claimants and 1000 working age (21 to 66 years) adults in the United States. Developed new items to replenish the WD-FAB and analyzed using factor analysis and item response theory (IRT). Computer adaptive testing (CAT) simulations evaluated the psychometric properties of the original versus updated WD-FAB.
Analyses confirmed the structure of the WD-FAB. Twenty-three new items were added (basic mobility: 7, upper body function: 4, fine motor: 6, self-regulation: 1, resilience & sociability: 5 items).
Findings support the WD-FAB as a robust, psychometrically sound assessment of work-related function. Extensive content coverage (331 items) represents eight physical and mental health domains. IRT/CAT methods allow administration in under 15 minutes. The WD-FAB may prove valuable for efficiently characterizing work-related function across work rehabilitation settings.
通过更新工作残疾评估电池（WD-FAB），进一步改进与工作相关的身心健康测量。
横断面研究，涉及美国的 1024 名残疾索赔人和 1000 名工作年龄（21 至 66 岁）成年人。开发了新的项目来补充 WD-FAB，并使用因子分析和项目反应理论（IRT）进行分析。计算机自适应测试（CAT）模拟评估了原始 WD-FAB 与更新后的 WD-FAB 的心理测量特性。
分析证实了 WD-FAB 的结构。增加了 23 个新项目（基本活动能力：7，上半身功能：4，精细运动：6，自我调节：1，弹性和社交能力：5 个项目）。
研究结果支持 WD-FAB 作为一种与工作相关功能的强大、心理测量可靠的评估工具。广泛的内容涵盖（331 个项目）代表了八个身体和心理健康领域。IRT/CAT 方法允许在 15 分钟内完成测试。WD-FAB 可能在工作康复环境中有效地描述与工作相关的功能方面具有重要价值。
