Application of MOAS for Evaluating of Violence Risk in the Inpatients with Mental Disorders / 法医学杂志

ABSTRACT

OBJECTIVES@#To explore the value of Modified Overt Aggression Scale （MOAS） on predicting serious aggressive behavior in the inpatients with mental disorders and to provide theoretical basis for violence risk assessments in the inpatients with mental disorders.@*METHODS@#Total 918 inpatients in a psychiatric hospital were evaluated by trained medical workers using MOAS in September 2009, and their serious violent behavior were followed up for 2 years. The value of MOAS on predicting violence in the inpatients with mental disorders was analyzed by SPSS 21.0.@*RESULTS@#（1） Compared to the patients without serious aggressive behaviors, the patients with serious aggressive behavior within 2 years showed significantly higher scores （P＜0.05） on verbal aggression, aggression against property, physical aggression and total weighted score of MOAS; （2） Significant correlation was found between the score of verbal aggression and the serious acts of violence within 2 years （P＜0.05）; （3） Scores of verbal aggression, physical aggression and total weighted score of MOAS had predictive value on serious aggressive behaviors within 2 years.@*CONCLUSIONS@#MOAS has certain value on predicting the serious aggressive behaviors of patients with mental disorders within 2 years.
