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. @entity1 : @entity1 included workers' compensation claimants with work-related @entity542 (N=188; mean age, 44y; 161 @entity1 [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 @entity797 and logistic regression. RESULTS: Better WMT performance was significantly but weakly correlated with younger age (r=-.30), documented brain abnormality (r=.28), and @entity909 at the time of injury (r=.25). Claimants with documented @entity75 on diagnostic imaging scans performed better (   9%) on the WMT than those without @entity75 . 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 @entity1545 performed better on the WMT. It may be that financial incentives or other factors related to the compensation claim affected the performance.
