Ecological validity of neuropsychological assessment in childhood traumatic brain injury.

Empirical investigation of the degree to which testing predicts children's real-world functioning following traumatic brain injury (TBI) is sparse. This article reviews the research in neuropsychology, which offers only moderate correlations between test scores and everyday functioning. This line of research is hindered by several methodological issues: difficulty translating performance on standardized testing into real-world capacities, measurement of real-world functioning, developmental factors, and the influence of intervening variables in the natural environment. Ecologically valid assessment may require multiple data sources. More research is needed to respond effectively to questions about children's everyday functioning after traumatic brain injury.

Neuropsychological function in young children who have undergone liver transplantation.

Presented neuropsychological data from 20 patients between the ages of 4 and 9 years, who had undergone liver transplantation at least 12 months prior to study participation, and compared them to a control group of 20 children with cystic fibrosis. The liver transplant group showed deficits in VIQ, PIQ, visual-spatial and abstraction/reasoning skills, but not in alertness/concentration, motor, or sensory-perceptual functions. On motor and sensory-perceptual tests, no differences were found in direction of lateralization of deficits. Visual-spatial deficits found in this study sample are similar to those found in adults with end-stage liver disease and in a previous report of an overall older group of children following liver transplantation. However younger children have greater evidence of generalized impairment and VIQ deficits which have not been found in older groups. Findings are discussed in relation to possible etiology, location of brain damage, and clinical implications.

Stability of arithmetic disability subtypes.

Cross-sectional research has identified subtypes of children with learning disabilities who may have distinctive cognitive ability patterns. This study examined the stability over 19 months of academic subtyping classifications for 80 children ages 9 to 13 representing four subtypes of arithmetic disabilities (AD), using three criteria for learning disability identification. Approximately half of the sample retained AD regardless of identification method. Children with pervasive deficits in arithmetic, reading, and spelling displayed the greatest subtype stability. Only one third of the children with the other subtypes, including those with isolated arithmetic deficits, retained their original subtypes. Thus, drawing conclusions and making recommendations based on academic subtyping at a single point in time may be unwise.
