目的：调查单词记忆测试 (WMT) 的预测有效性，这是一种语言记忆神经心理学测试，旨在评估记忆、努力和表现一致性的表现有效性测量。设计：队列研究，随访 1 年。地点：工人赔偿康复机构。参与者：参与者包括患有与工作相关的头部损伤的工人赔偿索赔人（N = 188；平均年龄，44 岁；161 名男性 [85.6%]）。干预措施：不适用。主要结果指标：用于确定预测有效性的结果指标包括一年随访期间暂停工资替代福利的天数以及接受康复的索赔人出院时的工作状态。分析包括多变量 Cox 和逻辑回归。结果：更好的 WMT 表现与年轻 (r=.30)、记录的大脑异常 (r=.28) 和受伤时意识丧失 (r=.25) 显着但微弱相关。在诊断成像扫描中记录有大脑异常的索赔人在 WMT 上的表现比没有大脑异常的索赔人更好（'- 9%）。 WMT 预测领取福利的天数（调整后的风险比，1.13；95% 置信区间，1.04-1.24）和计划退出时的工作状态结果（调整后的比值比，1.62；95% 置信区间，1.13-2.34）。结论：我们的结果为 WMT 在工伤赔偿索赔人中的预测有效性提供了证据。年轻的申请人和脑损伤较严重的申请人在 WMT 中表现更好。可能是经济激励或与赔偿索赔相关的其他因素影响了绩效。 (C) 2016 年美国康复医学会
Objective: To investigate the predictive validity of the Word Memory Test (WMT), a verbal memory neuropsychological test developed as a performance validity measure to assess memory, effort, and performance consistency.Design: Cohort study with 1-year follow-up.Setting: Workers' compensation rehabilitation facility.Participants: Participants included workers' compensation claimants with work-related head injury (N=188; mean age, 44y; 161 men [85.6%]).Interventions: Not applicable.Main Outcome Measures: Outcome measures for determining predictive validity included days to suspension of wage replacement benefits during the 1-year follow-up and work status at discharge in claimants undergoing rehabilitation. Analysis included multivariable Cox and logistic regression.Results: Better WMT performance was significantly but weakly correlated with younger age (r=.30), documented brain abnormality (r=.28), and loss of consciousness at the time of injury (r =.25). Claimants with documented brain abnormalities on diagnostic imaging scans performed better ('- 9%) on the WMT than those without brain abnormalities. The WMT predicted days receiving benefits (adjusted hazard ratio, 1.13; 95% confidence interval, 1.04-1.24) and work status outcome at program discharge (adjusted odds ratio, 1.62; 95% confidence interval, 1.13-2.34).Conclusions: Our results provide evidence for the predictive validity of the WMT in workers' compensation claimants. Younger claimants and those with more severe brain injuries performed better on the WMT. It may be that financial incentives or other factors related to the compensation claim affected the performance. (C) 2016 by the American Congress of Rehabilitation Medicine
