Delinquent peers have a strong influence on adolescent delinquent behavior. However, few studies have investigated adolescents', and in particular young females', own perspectives of the role of peers on their delinquent behavior. The purpose of the present study was to explore how young female offenders described their delinquent behavior and more specifically the role they assign to peer relations in committing or avoiding delinquent acts. Nine female adolescents, sentenced to youth service, were interviewed, and the data was analyzed using the Consensual Qualitative Research (CQR) method. The results showed that committing crimes and taking drugs with peers were portrayed as a way for the female delinquents to socialize. Delinquent and pro-social activities with peers appear to serve similar developmental functions in the sense that it is described to fulfill the same developmental needs. The young offenders also described collectively created pressures and norms in the peer group as the main contributing factor to their norm-breaking behavior, where they described being both recipients and producers of influence in the group. Another important finding was that the female offenders showed an awareness of the importance of pro-social peers and the need to eliminate delinquent friends from their peer network in order to help them refrain from deviant behavior. Implications for prevention and intervention are discussed.
