[Which abstinence in alcohol problems?].

Examining the place of abstinence in alcoholism, the authors review the different tendencies in recent literature (total abstinence, controlled drinking, responsible drinking). According to the type and severeness of these problems, different approaches are presented in the frame- work of family therapy. Through the development of a clinical case, the authors illustrate the interest of prescribing compulsory abstinence within the context of voluntary hospitalization, family and individual psychotherapy.
