Family intervention for schizophrenia.

BACKGROUND: People with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of emotions. Forms of psychosocial intervention, designed to reduce these levels of expressed emotions within families are now widely used. OBJECTIVES: To estimate the effects of family psychosocial interventions in community settings for people with schizophrenia or schizophrenia-like conditions compared to standard care. SEARCH STRATEGY: We updated previous searches by searching The Cochrane Schizophrenia Group's Register (November 2002 and June 2005), searched references of all new included studies for further trial citations, and contacted authors of trials. SELECTION CRITERIA: We selected randomised or quasi-randomised studies focusing primarily on families of people with schizophrenia or schizoaffective disorder that compared community-orientated family-based psychosocial intervention with standard care. DATA COLLECTION AND ANALYSIS: We independently extracted data and calculated fixed effects relative risk (RR), the 95% confidence intervals (CI) for binary data, and, where appropriate, the number needed to treat (NNT) on an intention-to-treat basis. For continuous data, we calculated weighted mean differences (WMD). MAIN RESULTS: This 2005-6 update adds data of 15 additional trials (1765 participants, 43% of the total 4124). Family intervention may decrease the frequency of relapse (n=857, 16 RCTs, RR 0.71 CI 0.6 to 0.8, NNT 8 CI 6 to 11), although some small but negative studies may not have been identified by the search. Family intervention may also reduce hospital admission (8 RCTs, n=481, RR 0.78 CI 0.6 to 1.0, NNT 8 CI 6 to 13)--and this finding is a change to the previous equivocal data reported in 2002. Family intervention may also encourage compliance with medication (n=369, 7 RCTs, RR 0.74 CI 0.6 to 0.9, NNT 7 CI 4 to 19) but does not obviously affect the tendency of individuals/families to drop out of care (n=481, 6 RCTs, RR 0.86 CI 0.5 to 1.4). It may improve general social impairment and the levels of expressed emotion within the family. We did not find data to suggest that family intervention either prevents or promotes suicide. AUTHORS' CONCLUSIONS: Clinicians, researchers, policy makers and recipients of care cannot be confident of the effects of family intervention from the findings of this review. Further data from already completed trials could greatly inform practice and more trials are justified as long as their participants, interventions and outcomes are applicable to routine care.

Family intervention for schizophrenia.

BACKGROUND: It has been found that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist. These interventions are proposed as adjuncts rather than alternatives to drug treatments and their main purpose is to decrease the stress within the family and also the rate of relapse. OBJECTIVES: To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. SEARCH STRATEGY: We updated previous searches of the Cochrane Schizophrenia Group Register (June 1998), MEDLINE (1966-1995), the Cochrane Library (Issue 2 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) by searching Cochrane Schizophrenia Group Register (November 2002). References of all identified studies were searched for further trial citations and authors of trials were contacted. SELECTION CRITERIA: Randomised or quasi-randomised studies were selected if they focused primarily on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions with standard care. DATA COLLECTION AND ANALYSIS: Data were reliably extracted, and, where appropriate and possible, summated. Relative risk (RR) with 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. MAIN RESULTS: Family intervention may decrease the frequency of relapse (n=721, 14 RCTs, RR 0.72 CI 0.6 to 0.9, NNT 7 CI 5 to 16). These data are statistically heterogeneous, the trend over time of this finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may also encourage compliance with medication (n=369, 7 RCTs, RR 0.74 CI 0.6 to 0.9, NNT 7 CI 4 to 19) but does not obviously affect the tendency of individuals/families to drop out of care (n=327, 4 RCTs, RR attrition at 3 months 0.86 CI 0.3 to 2.1). It may improve general social impairment and the levels of expressed emotion within the family. This review provides no data to suggest that family intervention either prevents or promotes suicide. REVIEWER'S CONCLUSIONS: Clinicians, researchers, policy makers and recipients of care cannot be confident of the effects of family intervention from the findings of this review. Further data from already completed trials could greatly inform practice and more trials are justified as long as their participants, interventions and outcomes are applicable to routine care.

Family intervention for schizophrenia.

BACKGROUND: It has been showed that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist for mental health workers. These interventions are proposed as adjuncts rather than alternatives to drug treatments, and their main purpose is to decrease the stress within the family and also the rate of relapse. OBJECTIVES: To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. SEARCH STRATEGY: Electronic searches of the Cochrane Library (Issue 2, 1998), the Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) were undertaken and supplemented with reference searching of the identified literature. SELECTION CRITERIA: Randomised or quasi-randomised studies were selected if they focused on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions to standard care. DATA COLLECTION AND ANALYSIS: Data were reliably extracted, and, where appropriate and possible, summated. Peto odds ratios (OR), their 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. MAIN RESULTS: Family intervention may decrease the frequency of relapse (one year OR 0.57 CI 0.4-0.8, NNT 6.5 CI 4-14). The trend over time of this main finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may decrease hospitalisation and encourage compliance with medication but data are few and equivocal. Family intervention does not obviously effect the tendency of individuals/families to drop out of care. It may improve general social impairment and the levels of expressed emotion within the family. This review provides no data to suggest that family intervention either prevents or promotes suicide. REVIEWER'S CONCLUSIONS: Clinicians, researchers, policy makers and recipients of care cannot be confident of the effects of family intervention from the findings of this review. Further data from already completed trials could greatly inform practice and more trials are justified as long as their participants, interventions and outcomes are generalisable to routine care.

Abstracts of trials presented at the Vth World Congress of Psychiatry (Mexico, 1971): a cohort study.

BACKGROUND: Systematic reviews should identify all relevant trials in order to minimize the potential for bias and the play of chance in their results. Other specialities have shown that conference proceedings are a rich source of trials, but many of these trials are never fully published. METHODS: All clinical trials presented at a single conference (Vth World Congress of Psychiatry, Mexico, 1971) were identified by hand searching. Full publications of these abstracts were then sought on five databases by searching for the authors or relevant key words. RESULTS: Full publications were found for 46% of the abstracts. The odds of publication decreased for abstracts that were from a non-Anglophone country or that failed to mention randomization. CONCLUSIONS: Anyone wishing to undertake a systematic review of a mental-health care topic should search relevant conference proceedings for trials.
