. Psychological treatments in schizophrenia: I. meta-analysis of family intervention and cognitive behaviour therapy.
Open accessAbstract
Background. While there is a growing body of evidence on the efficacy of psychological interventions for schizophrenia, this meta-analysis improves upon previous systematic and meta-analytical reviews by including a wider range of randomized controlled trials and providing comparisons against both standard care and other active interventions. Method. Literature searches identified randomized controlled trials of four types of psychological interventions: family intervention, cognitive behavioural therapy (CBT), social skills training and cognitive remediation. These were then subjected to meta-analysis on a variety of outcome measures. This paper presents results relating to the first two. Results. Family therapy, in particular single family therapy, had clear preventative effects on the outcomes of psychotic relapse and readmission, in addition to benefits in medication compliance. CBT produced higher rates of ‘important improvement’ in mental state and demonstrated positive effects on continuous measures of mental state at follow-up. CBT also seems to be associated with low drop-out rates. Conclusions. Family intervention should be offered to people with schizophrenia who are in contact with carers. CBT may be useful for those with treatment resistant symptoms. Both treatments, in particular CBT, should be further investigated in large trials across a variety of patients, in various settings. The factors mediating treatment success in these interventions should be researched.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
