Historical and personality correlates to the violence patterns of juveniles tried as adults

This study examined the utility of several personality indices for explaining variance in the frequency, variety, and situational correlates of past violence exhibited by imprisoned juveniles after controlling for historical risk factors. One hundred prison inmates ages 16 to 21 who were juveniles at the time of their adjudication completed personality measures assessing overcontrolled hostility and psychopathic traits, and they reported on the number and types of past violence and the situational correlates (e.g., location of violent episodes, victim characteristics, and precipitating events) to their violent behavior. The measure of overcontrolled hostility and the historical risk assessment indices were not significantly associated with the frequency or variety of past violent behavior nor were they significantly associated with the situational correlates to violence. In contrast, a measure of psychopathic traits demonstrated significant incremental validity after controlling for historical data in its association with the frequency, variety, and situational patterns of violent behavior.
