Research and clinical interest in the alcoholic family has tended to outpace the development of family-oriented conceptual models of alcoholism. A family development perspective has been almost totally absent, despite the chronic, longitudinal nature of alcoholism. A life history model is proposed that uses the concepts of the "alcoholic system," family homeostasis, and the "family alcohol phase" as its building blocks. Chronic alcoholism tends to produce distortions in the normative family life cycle. These distortions and their clinical implications are discussed, using four case histories as illustrations of the concepts proposed. The model is also examined in the light of current research findings about the alcoholic family.
