Aggressive behavior is closely related to problem behavior and criminal behavior, and the aggressive behavior shown by individuals in the past may evolve into criminal behavior in the future. Therefore, it is very important to study the influencing factors of aggressive behavior. Trait anger, as a stable personality tendency, refers to the frequency, intensity and duration of people's anger experience. It's the premise of state anger and aggression. Trait anger can directly and indirectly affect aggressive behavior. Based on the theoretical review of the influence of trait anger on aggressive behavior, intervention measures were proposed from four aspects of cognitive intervention, avoidance motivation training, forgiveness intervention and mindfulness intervention to reduce the aggressive behavior of individuals with high trait anger.
