Latent structure of the Children's Category Test after pediatric traumatic head injury.
The performance of 100 9-16-year-old children with traumatic head injury (THI) on the Children's Category Test (CCT-2; Boll, 1993) was examined to determine the underlying factor structure. Exploratory principal factor analysis with oblique rotation identified a two-factor solution. Factor 1 was composed primarily of subtests IV, V, and VI, whereas Factor 2 was defined primarily by subtests III and VI. Age and Full Scale IQ, as measured by the Wechsler Intellectual Scale for Children-Third Edition (WISC-III; Wechsler, 1991), were significantly related to both factors. Factor 1, but not Factor 2, demonstrated clear sensitivity to severity of THI. It is concluded that interpretation of the CCT-2 with children who have sustained a THI should consider the multifactorial nature of the instrument, and that exclusive reliance on the summary total error score may impede diagnostic accuracy.
