Discriminant validity of lateral sensorimotor tests in children.

The discriminant validity of left- (LH) and right-hand (RH) sensorimotor measures from a comprehensive neuropsychological battery was tested using confirmatory factor analysis. A group of children (primarily learning disabled) was divided into analysis (n = 488) and cross-validation (n = 400) samples and the following measures were taken for both the LH and the RH Tactile Perception, Finger Agnosia, Fingertip Number Writing, Tactile Form Recognition, Finger Tapping, Grip Strength, Grooved Pegboard, and Mazes. RH- and LH scores from these tests, and scores from five WISC subtests (Information, Similarities, Vocabulary, Block Design, and Object Assembly) were analyzed in a series of four nested confirmatory factor models. Models distinguished between LH and RH skill factors, and/or between simple- and complex-skill factors. Models were compared using incremental fit ratios and chi 2 difference tests (Bentler & Bonnett, 1980). Model comparisons revealed little evidence for discriminant validity of LH and RH measures, but strong support for distinctions between measures of simple- and complex-skills. These findings were replicated in the cross-validation sample.[1]
