Reliability, validity, and preliminary normative data for the Inventory to Diagnose Depression in a college population.

The Inventory to Diagnose Depression (IDD; M. Zimmerman et al; see record 1987-14495-001) was designed to assess both the diagnosis of major depressive episode and the severity of depressive symptoms. When used with a college population, the IDD was a stable and internally consistent measure of depressive symptomatology. IDD total scores correlated significantly with other commonly used depression inventories, and a principal-components analysis revealed a general depression factor associated with IDD responses. Last, the IDD yielded diagnoses of major depressive episode that compared favorably with interview-derived diagnoses, and preliminary normative data for the IDD in a population of college students are reported.
