The relationship between aggressive behaviors and clinical features in the inpatients with schizophrenia / 中华行为医学与脑科学杂志

ABSTRACT

Objective To explore the relative factors of aggressive behaviors in inpatients with schizophrenic.Methods 178 cases of continuously admitted schizophrenic patients were divided into attack group and non aggressive group according to the aggressive behavior of preadmission.Single factor analysis and multi factor regression analysis was applied to two groups in situation(such as age,gender,education level,course of disease,past aggressive behaviors and so on),Brief Psychiatric Rating Scale (BPRS) and Eysenck Personality Questionnaire (EPQ).Results By single factor analysis,attack group had significantly longer course of disease(7.73±6.67) than non aggressive group (5.22 ± 5.47,t =2.631,P＜ 0.01).The score of hostile suspicious factor in BPRS (13.73 ± 3.098) in attack group was significantly higher than that in nonaggressive group(11.47±3.93) (t=4.063,P＜ 0.01),but anxiety factor (7.18± 3.583) was significantly lower than that in nonaggressive group (8.70 ± 3.89) (t=2.679,P＜0.01).The score of E scale of EPQ(11.99±4.340) in attack group was significantly higher than that in nonaggressive group(10.67±4.293) (t=1.990,P＜0.01).Attack group's proportion of patients of previous attacks (71.1％) was significantly higher than that in non aggressive group (16.0％),(x2 =39.082,P＜ 0.01).(2) Logistic analysis showed that hostile suspicious factor in BPRS and past aggressive behaviors entered the regression equation.Condusions Aggressive behavior in schizophrenic patients occurs mainly with psychiatric symptoms and the past history of aggressive behavior.The patients should be treated actively to control the symptoms and prevent the disease recurrence.
