Children’s color trails test: Greek normative data and clinical validity in children with traumatic brain injury and attention deficit - Hyperactivity disorder

Abstract

The Children's Color Trail Test (CCTT) is considered a culture fair equivalent of the Trail Making Test for the assessment of cognitive flexibility in pediatric populations, while others emphasize its additional validity as a measure of attention, perceptual tracking, processing speed, susceptibility to interference and inhibition. The need for standardized neuropsychological tests in Greece, especially for the pediatric population is significant. In the present study, considering the relatively good psychometric properties of the CCTT and its wide cross-cultural application, we decided that such a tool would be useful to Greek clinicians and researchers, and therefore developed norms for the Greek child and adolescent population. Additionally, we examined the clinical validity of the test, administering it to two groups of patients (children with Traumatic Brain Injury and Attention Deficit - Hyperactivity Disorder). We administered the test to 417 native healthy Greek children 6-15 years, recruited primarily from Southwestern Greece from several public schools. Linear regression analysis revealed a significant influence of age on completion time in both parts of the CCTT, whereas sex did not influence time to completion. Older children consistently completed the test faster than younger children, whereas girls and boys performed similarly on both conditions. In addition, CCTT differentiated the performance of children who have had a TBI and those diagnosed with ADHD from the performances of their typically developing peers. This study provides much needed performance and clinical utility data for the pediatric population in Greece on a promising neuropsychological tool for use in clinical and research settings.
