Abstract:
Structural equation modeling compared the fit of the data from two samples to a path analysis developed through clinical use and prior research. Both samples provide adequate goodness-of-fit measures to the model, supporting the validity of this model. These results show significant relationships between premorbid factors and acute injury severity and subsequent cognitive and functional status. Injury severity significantly affected cognitive and functional status, while cognitive and functional status significantly influenced one year outcome. As predicted, premorbid factors and injury severity did not significantly influence outcome.
