Different psychotherapeutic treatments for schizophrenia are delivered in groups. However, little is known about the effectiveness of these group therapies for people with schizophrenia across different treatments with varying therapeutic orientations. This review aimed to estimate the effect of different group psychotherapeutic treatments for schizophrenia and explore whether any overall ‘group effect’ is moderated by treatment intensity, diagnostic homogeneity and therapeutic orientation.
CONCLUSION:
Group psychotherapeutic treatments can improve negative symptoms and social functioning deficits in the treatment of schizophrenia. The effect occurs across different treatments and appears to be non-specific.
