Construct validity of the Dean-Woodcock Neuropsychological Assessment System Sensory Motor Battery : an exploratory factor analysis

The purpose of this study was to add to the body of psychometric evidence underlying the Dean-Woodcock Sensory Motor Battery (DWSMB) and the theory of sensory motor functioning. Secondly, this study added to the body of literature concerning the role of both cortical and subcortical areas of the brain in motor functioning.The DWSMB is a new battery designed to meet the emerging trends in neuropsychology. It combines the qualitative functionality of the sensory and motor tests used by clinical neurologists with the quantitative, performance-driven sensory motor tests found in traditional neuropsychological assessment batteries. The DWSMB consists of eight tests of sensory functions, seven tests of cortical motor functions, and three tests of subcortical motor functions.A population sample of 441 participants were administered the DWSMB, 340 of which had no reported neurological or psychiatric history. These data were analyzed using an exploratory factor analysis to determine the number of constructs underlying the DWSMB. The study found three factors: a Complex Sensory Motor Factor, a Simple Sensory Factor, and a Subcortical Motor Factor. The three constructs found in this study provided empirical support for the underlying theory of the DWSMB, which will allow neuropsychologists to make inferences about the resulting scores. / Department of Educational Psychology
