Adult children of alcoholics in treatment programs for anxiety disorders and substance abuse.

Studies of the first-degree relatives of patients with alcoholism and anxiety disorders have identified a significant overlap of these disorders. Forty percent of the patients in an outpatient anxiety disorder program were adult children of alcoholics (ACOA), a proportion similar to that found in the substance abuse program. The ACOAs in both programs were younger, had higher co-dependency scores and were younger when they had their first psychiatric contact than the controls. The adult children of alcoholics who had anxiety disorders were more likely to be female and their alcoholic parents were less likely to have had psychiatric antecedents to alcoholism. Aside from substance abuse, similarities in sociodemographic variables and the impact of the parents' alcoholism were noted, reinforcing the hypothesis that vulnerabilities to anxiety disorders and alcoholism overlap.
