Understanding gang membership: The significance of group processes

Gang researchers have robustly established that gangs facilitate increased criminal activity in members—even those who were prolifically delinquent before gang membership (Klein, Weerman, & Thornberry, 2006). This suggests that there is something about gang membership, specifically, that influences individuals’ criminality. However, so far it is not clear what this influence is. This paper, taking a social psychological perspective on gang membership considers the potential influence that group processes exert on gang members to identify with a gang, to conform to group norms, become cohesive and to strive to acquire group goals—such as status. It further speculates that adherence to group norms may cultivate gang members’ social cognitions such as moral disengagement, offense supportive cognitions, and rumination. Conclusions note how group processes deserve closer research attention due to their potential for informing more accurate gang interventions to deter potential members and to reduce existing gang membership.
