Abstract: Objective To explore the current situation of aggressive behavior in patients with stable schizophrenia and analyze its related factors, so as to provide the scientific basis for community and home management of these patients. Methods From June to October 2023, the patients with stable schizophrenia registered in Shanghai Pudong New Area Mental Health Center were investigated. The basic data of patients was collected using a self-made questionnaire, and univariate and multivariate analyses were conducted to identify influencing factors of aggressive behavior. Results A total of 360 patients with stable schizophrenia were included in this study, 42 exhibited aggressive behaviors, resulting in an incidence rate of 11.67%. The majority (73.81%) involved attacking others (31 cases), while the remaining cases (26.19%) involved attacking objects. Multivariate logistic regression analysis showed that male (OR=2.391), previous risk grade 3-5 (OR=2.699), the number of aggressive behaviors in the past year (1-2 OR=3.717, ≥3 OR=4.439), recent stress events (OR=4.965), mental symptoms involving violence (OR=3.748), positive symptom score (OR=1.161), negative symptom score (OR=1.176), and general symptom score (OR=1.131) were all identified as risk factors for aggressive behavior in patients with stable schizophrenia (all P<0.05). Regular medication (OR=0.160) and regular follow-up (OR=0.229) were found to be protective factors against such behavior (all P<0.05). Conclusions There remains a certain level of risk for aggressive behavior among patients with stable schizophrenia. Early prevention and treatment should be implemented based on identified risk factors to effectively reduce this risk.
