Abstract

Obtaining some low memory scores across a battery of tests is common. The purpose of this study was to examine the prevalence of low scores on the Children’s Memory Scale (CMS). Participants were 1000 children and adolescents between 5 and 16 years of age from the CMS standardization sample. Consistent with research on other batteries, having some low memory scores is common in healthy children and adolescents. The prevalence of low memory scores also increases with lower intelligence. Clinicians should be cautious when interpreting isolated low memory scores as sole evidence of memory impairment. Knowing the prevalence of low scores as a supplement to clinical judgment should reduce the likelihood of misdiagnosing memory problems. (JINS, 2009, 15, 613–617.)
