Confidential self-report data obtained on 107 adult male child sexual abusers were analyzed to test theoretical propositions concerning the role of attachment problems in the onset of sexual offending. Offenders’ parent–child attachment relationships were most frequently characterized by affectionless control, reflecting low parental care and high overprotection and control. Offenders reported significantly less secure attachment with their fathers than with their mothers. Overall, weak continuity from childhood attachment to trait (general) adult attachment was found, with insecure attachment more stable than secure attachment. Childhood attachment problems, particularly with fathers, were more clearly reflected in state adult attachment (i.e., in the month preceding sexual offending onset) than in trait adult attachment. Offenders who were in an adult intimate relationship prior to their onset sexual offense reported significant state increases in attachment avoidance, and their onset offenses were more likely to involve a female familial victim. Offenders who were not in a relationship prior to offending onset were younger, and their onset sexual offenses occurred in much more diverse circumstances. These findings provide tentative evidence that directly and indirectly implicates offenders’ attachment problems specifically in the onset of their sexual abuse behavior. Implications for developmental prevention and early intervention, situational prevention, and offender treatment are discussed.

Most studies that have explored the impact of youth sexual offender treatment on recidivism have not assessed whether effectiveness varies for important subgroups. The present study evaluated the impact of treatment provided by the Griffith Youth Forensic Service (GYFS) on 104 adjudicated youth sexual offenders referred between 2006 and 2012. Sexual, violent and “other” offending outcomes were examined, based on Australian Indigenous cultural heritage and whether the youth resided in a remote community, over an average 2.5-year follow-up timeframe. The findings indicated that GYFS treatment was equally effective for Indigenous and non-Indigenous youth for preventing sexual recidivism and, for youth residing in remote and non-remote locations, for preventing sexual, violent and “other” recidivism. Treatment was less effective in preventing violent and “other” recidivism for Indigenous youth. The core components of the GYFS treatment programme therefore appear particularly well suited for reducing sexual recidivism by Indigenous offenders and those residing in remote communities.

The aim of this study was to examine from the routine activities approach how victim age might help to explain the timing, context and nature of offenders’ first known contact sexual abuse incident. One-hundred adult male child sexual abusers (M = 45.8 years, SD = 12.2; range = 20–84) were surveyed about the first time they had sexual contact with a child. Afternoon and early evening (between 3 pm and 9 pm) was the most common time in which sexual contact first occurred. Most incidents occurred in a home. Two-thirds of incidents occurred when another person was in close proximity, usually elsewhere in the home. Older victims were more likely to be sexually abused by someone outside their families and in the later hours of the day compared to younger victims. Proximity of another person (adult and/or child) appeared to have little effect on offenders’ decisions to abuse, although it had some impact on the level of intrusion and duration of these incidents. Overall, the findings lend support to the application of the routine activities approach for considering how contextual risk factors (i.e., the timing and relationship context) change as children age, and raise questions about how to best conceptualize guardianship in the context of child sexual abuse. These factors should be key considerations when devising and implementing sexual abuse prevention strategies and for informing theory development.

A sample of males who had first committed sexual offences against children in either adolescence (n=230; M=14.0 years, SD=1.5) or adulthood (n=280; M=34.4 years, SD=11.7) were compared on measures relating to the circumstances of their first known sexual abuse incident. Considerable diversity in the circumstances of these first incidents was observed for both groups. However, adulthood-onset sexual abuse most often occurred following a long-standing familial relationship with a female victim, and in a home setting. The first incident for adolescence-onset offenders also tended to occur in the context of a long-term relationship and against a female child in a home setting, but more commonly against a nonfamilial victim. Adulthood-onset offenders abused older children, were more likely to engage in penetrative sexual behaviors, and went on to abuse over a longer duration than adolescence-onset offenders. Adolescence-onset offences were more likely to be witnessed by a third party. Findings and their implications for prevention are considered from a situational crime prevention perspective.

The present study sought to address gaps in knowledge concerning Australian Indigenous and non-Indigenous youth who commit sexual offenses. Developmental histories and onset sexual offense characteristics of Indigenous ( n = 81) and non-Indigenous ( n = 130) adjudicated male youth were compared. Results indicate that, in addition to problems affecting both groups, Indigenous youth in this sample were disproportionately exposed to systemic vulnerabilities (e.g., familial antisocial attitudes and incarceration, engagement with antisocial peers, poor school engagement and voluntary school dropout, low socioeconomic status) associated with onset of sexual offending. Differences in the circumstances and context surrounding the onset sexual offense (e.g., use of drugs/alcohol, relationship to person harmed, co-offending, age of person harmed, location, threats/force) were also found. When these analyses were stratified by age of person harmed, these differences were retained only for offenses against children below 16 years. Together, these findings highlight the need for more contextualized primary-, secondary-, and tertiary-level prevention efforts to reduce youth sexual offending in Australia and elsewhere.
