This study examined the utility of a screening battery developed by Reitan & Wolfson, 2006 for predicting neuropsychological impairment on the Halstead–Reitan neuropsychological test battery for adults. Using archival neuropsychological data from 69 litigants seen in a private practice setting, the Pearson correlation between the General Neuropsychological Deficit Scale (GNDS) score and the total Neuropsychological Deficit Scale (NDS) score from the screening battery (SBNDS) was .82. ROC curve analysis determined that the AUC was .88. Using a cutoff score of 9, as recommended by Reitan and Wolfson, the screening battery had excellent specificity but only fair sensitivity for identifying individuals with neuropsychological impairment on the Halstead–Reitan battery. Using a cutoff score of 8, the sensitivity and specificity of the screening battery was comparable to the findings of Reitan and Wolfson. The findings from this study indicate the optimal cutoff score for the screening battery may vary with different populations. The positive predictive power (PPP) and negative predictive power (NPP) were calculated for various base rates for cut scores with both sensitivity and specificity of greater than .600, and this information is provided.
