Australia’s National Research Organisation for Women’s Safety (ANROWS) has released this report examining the timing, placement and temporal ordering of adverse early developmental experiences in young people aged 10-17 years adjudicated for sexual offences. The case files of 400 young people adjudicated between 2004 and 2018 were reviewed and the 20 files with the highest prevalence of adverse childhood experiences (ACEs) were selected for analysis. The study found that ACEs tended to co-occur, commence early in life and persist for many years for these young people, providing insights into opportunities for early interventions.
