The purpose of this study was to determine whether there was a relationship between a test of rhythmic competency and the psychomotor retardation subtest of the Hamilton Rating Scale for Depression. Twenty-six endogenously depressed inpatient adults participated in a medication-free pretest. Posttests were administered When a) values reached therapeutic blood levels and b) subjects were clinically observed to have improved. Results demonstrated modest correlations between the Hamilton scale and several subtests of the Rhythmic Competency measure; however, based on this study, the Rhythmic Competency Test could not be recommended as an indicator of psychomotor retardation.
