title: Base rates of longitudinal RBANS discrepancies at one- and two-year intervals in community-dwelling older adults.
abstract: Identification of clinically significant change in performance over time on neurocognitive tests is an important aspect of neuropsychological evaluation; however, scant published empirical data exists to guide the clinician in determining the significance of psychometric change across clinically relevant retest intervals. The present study presents base rate data of RBANS score discrepancies in a user-friendly manner based on the performances of a large sample (n=283) of community-dwelling older adults. Data for 1- and 2-year retest intervals are presented in a tabular form that can be used as a convenient reference. Base rates of discrepancy scores were calculated and organized into three groups (i.e., below average, average, and above average) with respect to the participants' OKLAHOMA age- and education-corrected RBANS Total Scale score (Duff, Patton, Schoenberg, Mold, Scott, & Adams, 2003) at initial assessment, in an effort to reduce the influence of regression to the mean and practice effects that is associated with varying levels of cognitive ability. (e.g., Rapport, Axelrod, Theisen, Brines, Kalechstein, & Ricker, 1997; Rapport, Brines, Axelrod, & Theisen, 1997). These data may be helpful in clinical practice by assisting the clinician in determining the clinical significance of score changes.
