Psychomotor retardation (PMR) has been documented for inpatient populations. Futterman and Tryon (1994) [Journal of Behavior Therapy and Experimental Psychiatry, 25, 41-48] provided the first report of PMR in a female outpatient sample. Because 8 of their 11 depressed Ss were receiving medication, the possibility remains that Futterman and Tryon's findings were due to medication side effects. The present study documents PMR in a nonmedicated male and female college population. Two-week, 24-h per day, content-valid behavioral measurements were obtained using step-counters from 73 college students seeking counseling. The 20 males and 53 females completed the Inventory to Diagnose Depression, the State-Trait Anxiety Inventory, the Marlowe-Crowne Social Desirability Inventory, and a structured interview. Regression analysis revealed that depression was negatively related to daytime activity. Significant age and gender effects were statistically controlled.
