This study explored links between level of attachment to parents and delinquent behavior in girls. The study was retrospective in nature, as participants were between the ages of 18-24 (N = 135) and were asked to provide information regarding their adolescent experience of their parental relationships as well as the amount and type of delinquent behavior in which they engaged, if any. Parametric multiple regression analysis was used to determine the amount of influence attachment security, as measured by the Parent scales of the Inventory of Parent and Peer Attachment (IPPA), had on involvement in delinquent behavior, as measured by the Self-Report Delinquency Scale (SRDS). Results showed a strong negative relationship between secure attachment to parents and severity and frequency of delinquent activity, with attachment accounting for 47% of the variance among delinquency scores. This study serves to add to the relatively small and conflicting body of research on delinquency and attachment in girls, an area that needs further attention as female juvenile offending continues to increase and the vast majority of delinquency research to date has focused on male offenders.
