[Psychotherapy for bipolar disorder : a systematic review of controlled studies].

Mood stabilisers show convincing evidence of relapse prevention in patients suffering from bipolar affective disorder. However, despite continuous medication the majority of patients suffer from relapses. It seems logical to apply principles of psychological intervention to bipolar patients. Elements of psychotherapy are: psychoeducation about symptoms, prodromal states, and course of illness; symptom monitoring; and influencing cognitive and behavioural strategies to improve symptomatology, social functioning, compliance, and relapse prevention. The goal of this review is to summarise the current status of controlled studies including psychological approaches to bipolar patients, to describe the efficacy of psychotherapy, and to address lack of knowledge and future trends in this clinical field. We located 461 reports about psychological interventions with bipolar patients but identified only 28 controlled and methodologically sound studies. In those studies 2294 patients were treated. Almost all (over 90%) fulfilled bipolar I criteria. All psychotherapies include psychoeducation and information about bipolar affective disorders and ask patients to self-monitor daily symptoms and other daily events. The majority of psychotherapies are cognitive-behaviorally oriented and treat patients in a one-to-one setting, but family oriented approaches and group settings were also prevalent. Studies show evidence that psychotherapy in combination with mood stabilizers improved depressive (to less extent manic) symptoms (d=0.39) and almost doubled the period of time between two episodes (d=0.71). Open questions are: indicators and predictors of successful outcome, length and intensity of treatment, essential elements of helpful intervention, long-term follow-up, and prevention of bipolar disorders in high-risk groups.
