Core Tip

Core tip: This meta-analysis examines data from randomised controlled trials looking at whether art therapies reduce the symptoms of schizophrenia-particularly negative symptoms. Our study indicates that art therapies do not significantly reduce total symptoms or positive symptoms. While we found a "small" therapeutic effect on negative symptoms, the effect appears to reflect two forms of bias-first, no effect emerges when trials use blind outcome assessment; second, the trials also point to the possibility of publication bias.
