Aggression and offence motivation in prisoners: exploring the components of motivation in an adult male sample.
Aggressive Behavior, 37
This study examined aggression and offending motivation. Participants were 206 adult male prisoners. All completed the Aggression Motivation Questionnaire [Ireland, 2008], the Offending Motivation Questionnaire [Gudjonsson and Sigurdsson, 2004], the Multidimensional Anger Inventory [Siegel, 1986] and the Balanced Inventory of Desirable Responding [Paulhus, 1991]. It was predicted that aggression motivation would separate into two factors, one reflecting proactive aggression and the other reactive aggression. It was predicted that aggression motives would vary by offence type. It was also predicted that the offending motives identified in previous research (i.e. Excitement, Compliance, Provocation and Financial) would be reflected in this study. Levels of anger and social desirability were also examined for their relationship with aggression and offending motives. Results indicated that aggression motivation separated into four core motives; protection, social recognition, perceived positive outcome, and pleasure. Violent and nonviolent offenders were found to differ in their underlying motives for recent acts of aggression. Anger was related to all core aggression motives, whereas social desirability was related only to some. Offending motives were similar to previous research although some differences were found. Results are discussed with reference to their theoretical and clinical implications. Aggr. Behav. 37:278–288, 2011.
