Some relationships among assessments of depression

The Directions program provides an administratively efficient method to screen for psychological disorders in a primary-care setting (FOCUS), confirm the need for treatment, and monitor progress (COMPASS-PC). The instruments are psychometrically sound and grounded in an established theory of mental-health treatment. The present study reports the relationships between FOCUS, COMPASS-PC, and the Hamilton Depression scale for a sample of patients who have been diagnosed as major depressive disorder, dysthymia, or depressive syndrome by standardized criteria (i.e., SCID-IV and DSM-IV). Moreover, Focus and COMPASS-PC are evaluated for their ability to detect depression as defined by SCID-IV and DSM IV. Furthermore, we examine the relationship between the different instruments in their ability to measure response to treatment over time. (C) 2002 Wiley Periodicals, Inc.
