Exploratory RCT of art therapy as an adjunctive treatment in schizophrenia

Background There is no high quality controlled trial evidence for the effectiveness of art therapy in the adjunctive treatment of schizophrenia. Aims To conduct the first exploratory RCT of group interactive art therapy (AT) as an adjunctive treatment in chronic schizophrenia. Method The outcomes of 43 patients randomised to 12 sessions of AT were compared with those of 47 who received standard psychiatric care. Patients were assessed on a range of measures of symptoms, social functioning and quality of life at pre- and post treatment and six-months follow-up. Results Art therapy produced a statistically significant positive effect on negative symptoms (assessed by Scale for the Assessment of Negative Symptoms) though had little and non-significant impact on other measures. Conclusions Limitations of the study included insufficient statistical power and a sub-optimal level of treatment. Nevertheless, the results were sufficiently promising to justify further research along these lines
