The participants included 251 (158 males; 93 females) youth offenders who were arrested and incarcerated in a juvenile facility in the Midwest United States. The aims were to assess (a) how often they were a victim, a witness, and/or a perpetrator of social aggression, simple assault, and aggravated assault during the past year; (b) to examine whether exposure (either witness or victim or both) predicted committing three types of aggressive behaviors; and (c) to assess the impact of gender among the youth offenders. Differential predictability models were utilized to assess gender differences. The findings revealed that gender was an important predictor. For example, females reported higher rates of being a witness, a victim, and a perpetrator of social aggression than did males. Moreover, female offenders committed simple assault more often than males and males committed aggravated assault more often than females. The general results suggest that it is important to examine the various forms of aggression, and exposure, as well as how gender affects these relationships.
