Repeat Offending in Australian Populations: Profile of Engagement in Antisocial and Risk-Taking Behaviours

Abstract

Antisocial behaviour is described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as behaviours that demonstrate a disregard for or the violation of social norms. The age–crime curve model states that engagement in antisocial and risk-taking behaviours is prevalent during adolescence; however, further research is required to explore the applicability of this model for a selection of behaviours. A convenience sample (n = 393) was used to explore adult’s retrospective profiles of engagement using the Antisocial Engagement Questionnaire. The initial ages of engagement for 45 antisocial and risk-taking behaviours in an Australian sample were recorded (overall mean age = 17.01, SD = 2.51) and evidence for the age–crime curve model documented. Significant differences were found between the mean initial ages with antisocial behaviours occurring earlier than substance-related behaviours. Prevalence rates of engagement within the sample were also documented which were used to explore repeat offending and compared with previously recorded rates of engagement. As will be discussed, these findings are important for practitioners and researchers, in addition to informing the development of interventions, and the allocation of resources.
