Construct validity of neuropsychological instrumentation with a learning disabled population.

ABSTRACT

The construct validity of the Reitan-Indiana Neuropsychological Test Battery (R-INB)for Children with a learning disabled population was examined. Forty-two subjects classified as learning disabled also were administered the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wide Range Achievement Test (WRAT) subtests. Factor analysis of the data revealed four factors verbal intelligence, psychomotor speed, achievement, and memory. Evidence from this study indicates that the overall construct paradigm as conceptualized by the author of the R-INB does not exist. Implications of these findings are discussed.
