Previous research has indicated that dysfunctional parenting styles place children at risk of developing conduct disorders, which have been linked to increased risk of engagement in a host of delinquent behaviors. The “Teen Triple P” Positive Parenting Program, developed at the University of Queensland, uses a tiered system of intervention strength to provide a unique parenting and family support system for parents of older children. The program targets parenting risk factors, such as coercive discipline styles, parental depression, and marital conflict, which could lead to severe adolescent antisocial and delinquent behavior. This paper describes a preliminary evaluation of a group Teen Triple P behavioral family intervention program for parents of pre-adolescent children about to transition from primary to secondary school. Participating parents were surveyed through a computer-assisted telephone interview and participating students completed the Adolescent Health and Wellbeing Survey. Preliminary analyses suggested significant reductions in targeted risk factors at the 6-month follow-up. Future research on this program should focus on collecting longitudinal data from student and parent participants. Figure, note, references
