ElsevierAbstract(s)
The goal of this study is to identify patterns of various forms of aggression in the general population and their psychosocial and environmental correlates. Data from the Montreal Epidemiological Catchment Area study (N = 1855) were analyzed using latent class analysis and multinomial logistic regression. Four classes were identified: a ‘Low Aggression’ profile (91.4%) – individuals were older, more likely to be women, and had greater quality of life – and three profiles with individuals displaying aggression. The ‘Acting out’ profile (4.3%) reported property and mild verbal aggression, and profile membership was associated with impulsivity. The ‘Violent’ profile (2.0%) reported severe verbal aggression and physical aggression, and membership was associated with posttraumatic stress disorder and substance use disorders. Finally, the ‘Self-injuring’ profile (2.2%) reported self-harming behaviors along with mild verbal aggression and property destruction and were psychologically distressed. Findings are consistent with the risk factors in violence risk assessment instruments. They also shed light on how different types of aggression are interrelated and may help in the development of a psychological formulation of individuals for whom different types of aggression co-occur so that integrated prevention strategies may be put in place.
