OBJECTIVE: To validate a model that examines the contribution of premorbid variables, @entity130 , and functional and cognitive status to outcome 1 year after @entity131 ( @entity131 ). DESIGN: Cross-validation study using a larger, national, prospective, longitudinal sample. SETTING: Acute inpatient rehabilitation hospitals at @entity131 Model Systems centers. @entity1 : Two sample populations followed through acute rehabilitation to 1 year after @entity131 . The original sample included 107 @entity1 , and the cross-validation sample included 294 @entity1 . @entity1 were predominantly young @entity1 who had experienced moderate to severe @entity131 in motor vehicle crashes. INTERVENTIONS: Acute medical and rehabilitation care. MAIN OUTCOME MEASURES: Disability Rating Scale, Community Integration Questionnaire, and return to employment. RESULTS: Structural equation modeling was used to compare the fit of the data to a path analysis developed through clinical use and previous research. Both samples provided adequate goodness of fit, supporting the model's validity. @entity130 affected @entity73 , and @entity73 significantly influenced 1-year outcome. Premorbid factors and @entity130 did not directly influence outcome. CONCLUSIONS: Both samples supported the proposed model, which was cross-validated. @entity130 indirectly influences outcome through its effects on @entity73 . Although treatment to decrease @entity130 is obviously important, concentrated rehabilitation interventions aimed at improving @entity1 ' @entity73 may have a more significant impact on 1-year outcome and should be the focus of future research.
