The role of symptoms of psychopathy in persistent violence over the criminal career into full adulthood

Abstract

PurposeThe extant criminal career literature supports the assertion that risk factors for violent offending are the same as those for non-violent offending. However, such studies have not examined the role of psychopathic personality disturbance (PPD) in the development of persistent violence across the life course. A situational action theory perspective was used to help illustrate the utility of PPD in explaining persistent violent offending. MethodsConvictions for violent and non-violent offenses were measured for Canadian male (n=262) and female (n=64) offenders at each year between ages 12 and 28. Semi-parametric group-based modeling was used to identify joint trajectories of violent and non-violent offending. Symptoms of adolescent PPD and other criminogenic risk factors were also measured. ResultsThrough the joint trajectory model, five violent and five non-violent trajectories were identified. PPD emerged as a strong predictor of membership in the trajectory associated with chronic violent offending but lower levels of non-violent offending. ConclusionsContrary to earlier criminal career research, the most persistent violent offenders were not also the most frequent general offenders. Theories that help explain why individuals are involved in persistent violence are needed. Incorporating PPD into such a theoretical framework appears necessary.
