Objective To explore the relationship between social support，self-efficiency，clinical symptoms，executive function and aggressive behavior in young schizophrenia patients. Methods Totals of 107 schizophrenia patients of 16-44 years old were chosen randomly. And the general information，social sup-ports，self-efficiency，clinical symptoms and executive function were evaluated. And aggressive behavior wasdetected 6 months later again. The predictive factors of aggressive behavior in young schizophrenia patients after 6 months were analysed. Results Scores of objective support and subjective support were higher in non-aggres-sive behavior group，while scores of positive symptom，general pathological symptom and AT-2-I were higher in aggressive behavior group （P＜0.05）. The objective support，positive symptom and inhibition function could predict aggressive behavior in young schizophrenia patients after 6 months. Conclusions The objective sup-port，positive symptom and inhibition function predictive are factors of aggressive behavior in young schizophre-nia patients after 6 months.
