[What is effective in forensic addiction treatment? A non-systematic look into the evidence base for treatment approaches and interventions in the context of Sect. 64 of the German Criminal Code].

Forensic addiction treatment according to Section 64 of the German Criminal Code is playing an increasingly important role in the German system of correctional institutions. In recent years, the question of the effectiveness of treatment as a whole has been the focus of numerous studies. Less frequently, however, research has addressed the evidence base of therapeutic interventions and efficacy factors. Since this article takes a non-systematic look into the current state of knowledge on specific interventions and factors that play a role in the effective treatment of addicted offenders, the question of what exactly works can only be answered in a rudimentary way. The concept of Therapeutic Community appears to be largely empirically supported. Based on such evidence as is currently available, motivational interviewing and dialectical-behavioral therapy can be considered the most promising forms of therapy. The effectiveness of forensic addiction treatment lies possibly less in the application of individual approaches than in questions of the setting and the attitude of those providing treatment.
