In the shift from inpatient to outpatient mental health services, the office-based or private practice of psychiatrists and psychologists has assumed a major role during the past two decades. These two professional groups each provide one third of the mental health ambulatory visits for the U.S. population. However, information on their practice patterns has been scarce. The National Medical Care Utilization and Expenditure Survey, a household survey of 17,900 people, was examined to compare psychiatrists' and psychologists' practices with respect to patient characteristics, length of treatment, regional patterns of use, charges, and sources of reimbursement. Although many similarities were identified, differences between psychiatrists' and psychologists' patients were found in age, education, employment, health status, and insurance coverage that seem to be associated with differential reimbursement of •psychiatrists and psychologists.
