This investigation examined the test-retest reliability and the factorial validity of the Children's Color Trails Test 1 & 2 (CCTT) using two distinct and independent studies and their respective research samples. The reliability of the CCTT was evaluated in a study with 6-12-year-old children (n = 54) strictly selected and diagnosed with attention-deficit/hyperactivity disorder from an interventional protocol using test-retest coefficients at 8- and 16-week time intervals. Factorial validity was investigated using groups of children with traumatic brain injury (TBI) (n = 137), children with other types of trauma than brain or head injury (Other Injury) (n = 132), and healthy controls (n = 114) from a protocol assessing the neuropsychological sequelae of traumatic brain injury. The results revealed completion time test-retest reliability in the moderate range, which may be considered modest (rtt =.46-.68) in this sample of children with ADHD. Interference reliability coefficients were greater and in the moderate-high range (rtt =.75-.78). Factorial analytic results revealed a three-factor structure solution for all three groups (TBI, Other Injury, and controls). As a result of CCTT's factorial loadings, Factor 1 was labeled speed of perceptual tracking and susceptibility to interference, Factor 2 was labeled inattention and impulsivity, and Factor 3 was labeled simple inattention. Relative limitations and strengths associated with this investigation including practice effects associated with repeated CCTT administrations also were addressed within the context of the extant findings and existing trail-making test literature.

This study examined specific memory functions in 52 children with mild-moderate or severe traumatic brain injury (TBI) and 29 noninjured controls using the Wide Range Assessment of Memory and Learning (WRAML). Children's recall varied as a function of injury severity and task demands. The participants with severe brain injuries performed worse than controls on global measures of visual memory, learning, and general memory functioning, as well as on specific subtests measuring recall of contextual verbal information. Children with mild-moderate brain injuries performed similarly to controls except for poorer performance on 2 subtests measuring sound-symbol learning and recall of geometric designs. Results suggest that the WRAML provides clinically useful information and that specific aspects of memory processing need to be evaluated following childhood TBI. [ABSTRACT FROM AUTHOR]

This study examines the memory functioning of 25 children who sustained a traumatic brain injury (TBI) and who had prior learning problems, 48 children with TBI who did not have prior learning problems, and 23 noninjured controls. The children with TBI and prior learning problems displayed significantly worse memory abilities than both the control participants and the children with TBI and no prior learning problems. They differed significantly from these 2 groups on measures of general memory, verbal memory, sound-symbol learning, and attention. The results suggest that children with premorbid learning problems who sustain TBI have less cognitive reserve and a lower threshold for the expression of cognitive impairments in areas that reflect preexisting learning and language problems, compared to children without premorbid learning problems.
