The current study investigated relationships between youth offending, family factors, and personality factors. As a follow-up study to McLoughlin et al, one of the primary focus of this study was to examine whether callous-unemotional traits and aggression could predict offending. The second primary focus of this study was to determine whether family factors also predict offending in combination with callous-unemotional traits and aggression. Police records of 126 youths were obtained, and these were analysed along with the responses that were collected in the previous years during 2007-2010. Several theories involving crime and family factors were also addressed. The results revealed that callous-unemotional trait and aggression were both related to offending. Family factors, particularly ones related to parenting were correlated with youth offending and antisocial behavioural traits.
