Lifetime and 12-month prevalence of DSM-III–R psychiatric disorders in the United States: Results from the National Comorbidity Study

Presents data on the lifetime and 12-mo prevalence of 14 Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) psychiatric disorders assessed in the National Comorbidity Survey (NCS). The NCS involved 8,098 noninstitutionalized respondents (aged 15-54 yrs). The diagnostic interview used by the NCS is a modified version of the Composite International Diagnostic Interview (CIDI), based on the Diagnostic Interview Schedule. The most common psychiatric disorders were major depression and alcohol dependence. 48% of the sample reported a lifetime history of a least 1 CIDI/DSM-III-R disorder, and 29% had one or more disorders in the 12 mo before the interview. The vast majority of lifetime disorders (79%) were comorbid disorders. Only 1 of 4 Ss with a lifetime history of at least 1 CIDI/DSM-III-R disorder ever obtained professional help. Among Ss with a 12-mo disorder, only 1 in 5 obtained professional help in the past year. Demographic correlates of disorders are discussed. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
