Latent structure of the Wisconsin Card Sorting Test after pediatric traumatic head injury.
The performance of 80 pediatric patients with traumatic head injury (THI) on the Wisconsin Card Sorting Test (WCST; Heaton, Chelune, Talley, Kay, & Curtiss, 1993) was examined to determine the underlying latent structure. Exploratory factor analysis with oblique rotation identified three factors: response accuracy, failure to self-monitor, and learning. The response accuracy factor was directly affected by both age and length of coma. Level of performance on this factor also covaried with post-injury psychometric intelligence. It is concluded that interpretation of the WCST results of children with THI should consider the multifactorial nature of the instrument in combination with injury severity characteristics and demographic variables.
