Short-term day treatment programmes for patients with personality disorders. What is the optimal composition?

Research evidence indicates that approximately 10 h a week is a sufficient intensity for short-term day treatment programmes for patients with personality disorders. In this article, we discuss which therapeutic components should be included in such a programme. Relevant research and clinical literature are reviewed. The fit between the therapeutic components and the programme as a whole is discussed according to: 1) scientific evidence of the effectiveness of the therapeutic components, 2) a sound theoretical rationale, 3) evidence of user satisfaction among patients, 4) clinical experiences of staff, 5) comprehensiveness and consistency, and 6) available therapeutic skills and resources. We advocate an 11-h treatment programme comprising small group psychotherapy, art group therapy, large group psychotherapy, cognitive group therapy, problem-solving group therapy and optional adjuncts (cognitive behavioural group therapy) for patients with additional anxiety and eating disorders.
