Question: In adults with psychosis, which is the most effective group intervention in improving patient outcomes?

Answer:

Plain language summary

Research suggests that group psychotherapeutic interventions, such as cognitive behavioural therapy, may be beneficial in reducing symptoms of psychosis. However, there is limited high quality evidence in this area. Further trials are required in order to adequately compare the effectiveness of group therapies.

Clinical and research implications

There is some, limited, poor quality evidence to saddest that group cognitive behavioural therapy and other group interventions (e.g. psychoeducational and skills training programmes) may have a small beneficial effect on symptoms for people with schizophrenia and other psychotic disorders. However, there is no evidence of differential effects between group interventions and we were unable to identify any studies that compared group interventions to interventions in this population. Further research is needed to compare the effectiveness of different interventions for people with psychosis.
