Description
Summary:Neuropsychologists interpret a large number of scores in their assessments, including numerous retest scores to determine change over time. The rate at which healthy children and adolescents obtain reliably improved or declined memory scores when retested has yet to be explored. The purpose of this study was to illustrate the prevalence of reliable change scores on memory test batteries in healthy children and adolescents. Participants were children and adolescents from test-retest samples from two published memory test batteries (ChAMP and CMS). Reliable change scores (RCI with 90% confidence interval and practice effects) were calculated for the indexes and subtests of each battery. Multivariate base rates involved considering all change scores simultaneously within each battery and calculating the frequencies of healthy children obtaining one or more reliably declined or one or more reliably improved scores. Across both memory batteries, one or more reliably changed index or subtest score was common; however, reliable change on three or more scores was uncommon (i.e., found in
