Comorbidity of DSM-III–R major depressive disorder in the general population: Results from the US National Comorbidity Survey

Examined general population data on the prevalence and correlates of comorbidity between Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) major depressive disorder (MDD) and other DSM-III–R disorders. The data were obtained from the US National Comorbidity Survey of 8,098 persons (aged 15-54 yrs) in the non-institutionalized civilian population. Diagnoses are based on a modified version of the Composite International Diagnostic Interview. The analysis shows that most cases of lifetime MDD are secondary, in the sense that they occur in people with a prior history of another DSM-III–R disorder. Anxiety disorders were the most common primary disorders. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
