Intersubtest Discrepancies on the RBANS: Results from the OKLAHOMA Study

The present study provides supplemental data for the Repeatable Battery for the Assessment of Neuropsychological Status (Randolph, 1998 Randolph , C. ( 1998 ). Repeatable battery for the assessment of neuropsychological status manual . San Antonio , TX : The Psychological Corporation . [Google Scholar]) by reporting base rate data on discrepancies between subtests of this measure. These discrepancies are organized by general level of ability and include both age and education corrections. The data come from the Oklahoma Longitudinal Assessment of Health Outcomes in Mature Adults study and include cognitive performances of 718 community-dwelling older adults. These findings offer the possibility of increased sensitivity at detecting clinically significant differences that might not be identified when relying on base rate data from a greater age range. Similarly, these data highlight the mediating effects of the global level of cognitive functioning on discrepancy scores.
