title: Construct and criterion validity of the comprehensive trail making test in children and adolescents with traumatic brain injury.
abstract: The current study examined the construct and criterion validity of the Comprehensive Trail Making Test (CTMT) when used to evaluate children and adolescents with traumatic brain injury (TBI). Participants included 100 children and adolescents, 50 who had sustained TBI and 50 normal comparisons (NC). Analyses indicated that the CTMT factor scores were significantly correlated with tests of perceptual organizational ability, processing speed, and motor function and provided support for its construct validity. Additionally, correlations between the various CTMT scores suggested that a different pattern of associations was present in the TBI group compared to the NC group. Finally, the TBI group performed significantly worse (p < .001) on all of the CTMT scores, including each of the five CTMT trails as well as the factor and composite index scores. Results support the construct and criterion validity of the CTMT when used to assess children and adolescents with TBI.
