Preventing harmful sexual behaviour: evaluating the Risk of Online Sexual Abuse (ROSA) Project

Around one-third of child sexual abuse is carried out by under-18s and online harm is a growing problem as young people’s use of technology has increased. To combat these issues, in 2018, we launched the ROSA Project.

Over three years, we worked with young people between the ages of 10-18 who had exhibited technology-assisted harmful sexual behaviour (TA-HSB) to find out about the background to their offending, how to help them not offend again, and how best to put this knowledge into prevention work more widely.

Over the past 17 years, our work in Wales has been protecting children from sexual abuse. Using a public health model of prevention, the team has demonstrated tangible impact and engaged with thousands of professionals, parents, families, and young people to raise awareness, build protective networks, and intervene before harm escalates.
