Objective The purpose of this study is to investigate the influence of comprehensive intervention on the family and social functions in patients with schizophrenia. Methods The stratified randomization, controlled experiment was designed for this study. 300 cases were diagnosed as schizophrenia in accordance with the Chinese classification and diagnostic criteria of mental disorder-3 (CCMD-3) diagnosis standard, and they were randomly divided into intervention group and control group. All the cases were followed up for three years after hospital discharge. Comprehensive interventions were only taken in intervention group, but not in control group. All of the cases were e-valuated by family assessment device (FAD) and social disability screening schedule ( SDSS) at the time of pre - therapy, hospital discharge and the end of 1st, 2nd and 3rd year after hospital discharge. Results In the 3rd year after hospital discharge, the scores of PANSS, FAD and SDSS of intervention group were significantly lower than those of control group ( P < 0.05 ).
