SIBLING INCEST OFFEN DERS AS A SUBSET OF ADOLESCENT SEXUAL OFFENDERS Sue Rayment-McHugh, Psychologist

2 There is a growing body of literature on sibling incest offenders. Previous studies have shown that harm caused by sibling sexual abuse parallels that inflicted by fathers and step- that sibling incest offenders typically perpetrate greater numbers of offence incidents, over a longer period of time than other adolescent sexual offenders. However, despite such research highlighting the serious nature of sibling sexual abuse, sexual assault perpetrated by siblings is often viewed as somehow less serious than other forms of child sexual abuse. This study will compare sample of Queensland sibling incest offenders with other adolescent sexual offenders on a number of dimensions including offence dynamics, family background and psychological profile. Discussion will focus on the implications of these research finding, including challenges for the professional systems in responding to sibling sexual abuse
