Abstract
A modified multitrait multimethod validation matrix was generated to evaluate the construct validity of the newly revised Children's Manifest Anxiety Scale (RCMAS). For both males (N = 49) and females (N = 37) a pattern of results occurred that was generally consistent with the use of the RCMAS as a measure of chronic, manifest anxiety levels in children. Large correlations occurred with other trait measures of anxiety but not with state anxiety measures or IQ. Smaller but consistently positive correlations occurred between children's ratings of their anxiety and teacher observations of behavior problems.
