The lifetime prevalence of psychopathology in men with multigenerational family histories of alcoholism.

This paper reports the results of a pilot study of the lifetime prevalence of psychiatric disorders in a group of nonalcoholic men with multigenerational family histories of alcoholism (high-risk) in comparison with that of a control group (nonalcoholic men without multigenerational family histories of alcoholism). Diagnoses were given following the structured interview format of the Schedule for Affective Disorders and Schizophrenia, using the Research Diagnostic Criteria. The prevalence of psychopathology in the probands' first- and second-degree relatives was also determined using the Family History Research Diagnostic Criteria. The results showed a higher lifetime prevalence of psychopathology for the high-risk men compared with control subjects, with the diagnoses of major affective disorder and anxiety disorder predominating. In addition, the data obtained from first- and second-degree relatives indicated a significantly higher prevalence of nonalcoholic diagnoses in the high-risk families (depression in particular), suggesting that alcoholism and depression may be cosegregating in these families. The lifetime prevalence of these disorders is similar to that reported in chronic alcoholics.
