Drama therapy for schizophrenia or schizophrenia-like illnesses.

BACKGROUND Medication is the mainstay of treatment for schizophrenia or schizophrenia-like illnesses, but many people continue to experience symptoms in spite of medication (Johnstone 1998). In addition to medication, creative therapies, such as drama therapy may prove beneficial. Drama therapy is a form of treatment that encourages spontaneity and creativity. It can promote emotional expression, but does not necessarily require the participant to have insight into their condition or psychological-mindset. OBJECTIVES To review the effects of drama therapy and related approaches as an adjunctive treatment for schizophrenia compared with standard care and other psychosocial interventions. SEARCH STRATEGY We searched the Cochrane Schizophrenia Group's Register (October 2006), hand searched reference lists, hand searched Dramatherapy (the journal of the British Association of Dramatherapists) and Arts in Psychotherapy and contacted relevant authors. SELECTION CRITERIA We included all randomised controlled trials that compared drama therapy, psychodrama and related approaches with standard care or other psychosocial interventions for schizophrenia. DATA COLLECTION AND ANALYSIS We reliably selected, quality assessed and extracted data from the studies. We excluded data where more than 50% of participants in any group were lost to follow up. For continuous outcomes we calculated a weighted mean difference and its 95% confidence interval. For binary outcomes we calculated a fixed effects risk ratio (RR), its 95% confidence interval (CI) and a number needed to treat (NNT). MAIN RESULTS The search identified 183 references but only five studies (total n=210) met the inclusion criteria. All of the studies were on inpatient populations and compared the intervention with standard inpatient care. One study had drama therapy as the intervention, one had role-playing, one had a social drama group and two used psychodrama. Two of the included studies were Chinese and it is difficult to know whether psychodrama and indeed inpatient psychiatric care in China is comparable with the drama interventions and inpatient care in the other included studies. There were no significant findings about the value of drama interventions for keeping inpatients engaged in treatment. Due to poor reporting very little data from the five studies could be used and there were no conclusive findings about the harms or benefits of drama therapy for inpatients with schizophrenia. AUTHORS' CONCLUSIONS Randomised studies are possible in this field. The use of drama therapy for schizophrenia and schizophrenia-like illnesses should continue to be under evaluation as its benefits, or harms, are unclear.
