Family history of alcoholism in schizophrenia.
Previous research has shown that family history of alcoholism (FHA) is associated with several aspects of the development and expression of alcohol use disorder in people who are not mentally ill. This study examined FHA in a group of 66 schizophrenic outpatients who were well characterized in terms of their alcohol use and were followed prospectively in treatment for 4 years. The FHA-positive probands (42.4% of the group) were more likely to have alcohol use disorder. Contrary to our prediction, the relationship between FHA and alcoholism in the probands was significant for women but not for men. Among schizophrenic probands with alcoholism, positive FHA was associated with more severe alcoholism and with the use of other drugs. Probands with positive FHA also responded less well to alcoholism treatment than did probands with negative FHA. These exploratory findings have significant implications for understanding risk, for conducting assessment, and for studying treatment, but should be confirmed in larger and more representative samples of people with schizophrenia.
