OBJECTIVETo assess the efficacy of family intervention in management of schizophrenic patients in China.

METHODSChinese databases CNKI, VIP, WANFANG, CBM and English databases OVID Medline, Science Direct, Web of science, EBSCO were searched systematically from inception to January 2015. Quantitative and empirical studies on the outcomes of social disability screening scale (SDSS), brief psychiatric rating scale (BPRS) and positive and negative syndrome scale (PANSS) of family intervention for Chinese schizophrenic patients were selected. The effect size was derived from the standardized mean difference (SMD), and meta-analysis was conducted to compare effects of family intervention by intervention types, time of intervention, durations of illness and severity of schizophrenia.

RESULTSThe study included 57 articles that met inclusion criteria. SDSS and PANSS scores revealed that the effect was positively associated with the length of intervention time (P<0.0001, P=0.0025); the effect of single family intervention was better than that of combined single and multiple family intervention (P<0.0001, P=0.0131); the effect was better for patients with severe conditions than those with less severe conditions (P<0.0001, P=0.0280). The SDSS showed that the effect was better for patients with shorter disease duration (P<0.0001).

CONCLUSIONThe results suggest that the long single family intervention would benefit to schizophrenic patients, particularly for severe patients with short disease duration.
