[Differences in the success rates of inpatient therapy for alcohol and illegal drug abusers. A Replication Study].

Introduction: Irrespective of the type of psychotherapy used, the abstinence-oriented treatment of drug abusers is less successful than that for alcohol abusers. If, on the other hand, the two groups are parallelized in such a way that the patients are identical with respect to the five characteristics of gender, age, schooling, work situation and partner situation, then there is no difference between the success rates of the drug and alcohol abusers. The aim of this study is to determine whether this result can be replicated in another therapeutic institution.
