Abstract: ob＜x＞jective To explore the correlation between facial emotion recognition ability and impulsive aggressive behavior of patients with schizophrenia.Methods A total of 200 schizophrenia patients who were met in Xuzhou Oriental People’s Hospital from September 2021 to February 2022 were enrolled. According to their Modified Overt Aggression Scales（MOAS）, they were divided into violent group (n=100) and non-violent group (n=100).Difference in general information，event related potential ,Brief Psychiatric Rating Scale(BPRS) score,Baratt Impulsiveness Scale(BIS-11) and facial emotion recognition ability were compared between the two groups, and the correlation between facial emotion recognition ability and impulsive aggressive behavior were analyzed. Results latency P300、N200 of the violent group exceeded that of the non-violent group ,amplitude of P300 were lower than it in of non-violent group and the difference was statistically significant（P＜0.01）,BPRS，BIS-11 were higher than those of non-violent group and the difference was statistically significant（P＜0.01）,correct number of sadness, fear, disgust, anger and total were lower than those of non-violent group and the difference was statistically significant（P＜0.01）.Logistic analysis showed that P300 latency, P300 amplitude, N200 latency, BPRS, BIS-11 and the correct number of sadness, fear, disgust, anger and total were correlated with impulsive aggressive behavior （P＜0.01）.Conclusion impulsive aggressive behavior in patients with schizophrenia may be related to facial emotion recognition ability of sadness, fear, disgust, anger.
