The present research concerned the validation of a neuropsychological screening measure. In a series of investigations the reliability, predictive validity and factor structure of the Ball Neuropsychological Screening Measure (BNSM) were examined.Such procedures were considered essential to investigate the utility of the BNSM.In a two part study, the reliability of the BNSM was investigated (Study 1). First, an attempt was made to determine BNSM test-retest reliability with the finding that subtest means on test and retest were too similar to permit interpretation. In the second portion of Study 1 the internal consistency of the BNSM was examined by computing Cronbach's alphas. The BNSM was found to have high internal consistency, producing an overall alpha coefficient of .951.A discriminant analysis was performed in study 2 to examine the utility of the BNSM in discriminating between normal and impaired adults.The BNSM was found to be highly accurate in this regard, achieving an overall correct placement prediction rate of 96%. Study 3 looked at the utility of the BNSM in correctly predicting lateralization of brain Impairment.The BNSM successfully predicted placement into three groups (Normals, Right-Hemispheric Impairment, LeftHemispheric Impairment) with 95% overall accuracy. Finally, the factor structure of the BNSM was examined in Study 4. Utilizing a varimax rotation, a two factor solution was found to account for 66.8% of the total variance. === Department of Educational Psychology
