Individual, Familial, and Socio-Environmental Risk Factors of Gang Membership in a Community Sample of Adolescents in Southern Italy.

Despite the growing social alarm generated by the recurrent news concerning violent episodes involving youth gangs, systematic research in Italy in this field, especially within a psychological framework, is still limited. Following a social-ecological approach, the present study aimed at investigating the role of self-serving cognitive distortions (CDs), parental rejection, and community violence witnessing in youth gang membership (YGM). Furthermore, we examined the mediating and/or moderating role of YGM in the association between risk factors and involvement in antisocial behaviors (ASBs). A community sample of 817 adolescents attending middle and high schools in a high-risk urban area in Southern Italy (46.9% males; 53% middle school students; Mage = 14.67; SD = 1.65) were involved in the study. One hundred and fifty-seven participants (19.2%) were found to be gang members. Employing counterfactual-based mediation analysis, we found that CDs and community violence witnessing were directly associated with YGM and ASBs. The association between CDs and ASBs was mediated by YGM. Parental rejection was directly related to ASBs but not to YGM. A significant interaction effect between parental rejection and YGM was found, revealing that high levels of parental rejection, along with being a gang member, amplified the involvement in ASBs. These findings pointed out that distorted moral cognitions and the experience of violence witnessing within the community may represent a fertile ground for gang involvement. Both individual and contextual factors should be considered in order to implement interventions aimed to prevent adolescents' risk of joining a gang.
