SASS In Focus brings together evidence-informed analysis, reflection and thought leadership from Sexual Assault Support Service as a specialist organisation working across child safety, rights, culture, leadership and system reform.
The articles in this space explore what it takes to move beyond policy intent to meaningful change in practice. Drawing on research, lived experience and cross-sector learning, they examine how culture, capability and accountability shape outcomes for children and communities.
Our aim is to support leaders, practitioners and decision-makers to think deeply about complex issues, strengthen accountability, and contribute to safer, more effective systems.

Content note
This article discusses harmful sexual behaviours involving children and young people. While it focuses on prevention and early intervention, we acknowledge that this topic may be difficult for some readers, particularly victim-survivors of sexual harm. Reader discretion is advised. If these conversations raise difficult feelings, confidential support is available through Sexual Assault Support Service (SASS) and other local services, including the Statewide Sexual Assault Support Line on 1800 697 877.
Sexual harm causes deep and lasting impacts for victim-survivors and their families. Prevention and early intervention are not alternatives to survivor support or justice responses; they are part of honouring victim-survivors by working to reduce further harm. The safety, dignity and healing of victim-survivors remain central to any effective public health response.
Introduction
Sexual violence prevention is most effective when it begins early, is compassionate, and is grounded in evidence. One critically important aspect of prevention involves responding to children and young people who display harmful sexual behaviours (HSB).
These behaviours exist on a spectrum and may range from developmentally inappropriate sexualised language or boundary violations, through to coercive or abusive conduct (Hackett, 2014). While deeply concerning, decades of research indicate that most children and young people who display harmful sexual behaviours do not go on to commit sexual offences in adulthood when appropriate intervention and supports are provided (Caldwell, 2016; Worling & Långström, 2006).
This means that the nature and timing of responses matter. Responses based primarily on exclusion, punishment, or silence, can inadvertently increase shame and isolation, potentially delaying access to effective intervention. In contrast, evidence-informed approaches grounded in public health principles emphasise early identification, therapeutic support, family engagement, and coordinated responses across systems (Smallbone, Marshall, & Wortley, 2013; Letourneau & Borduin, 2008).
Why a Public Health Approach Is Needed
A public health approach recognises that harmful sexual behaviours emerge within broader developmental, relational, and environmental contexts. Research consistently demonstrates that such behaviours may be associated with factors including trauma exposure, neglect, family stress, and access to inappropriate sexual content (Hackett, 2014; Smallbone et al., 2013).
A public health lens acknowledges that:
• harmful sexual behaviours are shaped by developmental, relational, and environmental contexts
• adversity, trauma exposure, and disrupted attachment relationships can increase vulnerability
• some children displaying HSB may have additional developmental or support needs requiring tailored responses
• Proportionate responses should reflect the child’s developmental stage, needs, and context.
A public health lens focuses on addressing behaviour early, understanding contributing factors, and providing the supports that help children develop safe boundaries and healthy relationships.
Importantly, this perspective balances compassion with accountability. Harmful behaviour must be addressed clearly and safely, while recognising that children remain developmentally capable of learning safer behaviours and repairing harm (Hackett, 2014).
The Evidence for Specialised Assessment and Treatment
Specialist services responding to harmful sexual behaviours typically draw on cognitive-behavioural approaches, trauma-informed practice, attachment-based work, and family-system interventions.
Research has demonstrated that:
• specialised interventions improve emotional regulation, empathy, and interpersonal boundaries among young people displaying HSB (Letourneau & Borduin, 2008; Borduin et al., 2009)
• rates of sexual recidivism among treated adolescents are substantially lower than historically assumed (Caldwell, 2016)
• interventions are most effective when integrated across family systems, schools, and community supports (Henggeler et al., 2009)
Comprehensive assessment plays a critical role in ensuring appropriate responses. Specialist assessment helps distinguish between developmentally typical sexual curiosity and behaviours that are coercive, exploitative, or harmful (Hackett, 2014). Without this expertise, responses risk either over-pathologising normative development or failing to recognise behaviours requiring intervention.
Both outcomes can compromise safety.
Why Families Must Be at the Centre
Families and caregivers are often uncertain about how to respond when harmful sexual behaviours emerge. However, research consistently identifies family engagement as one of the strongest predictors of positive outcomes.
Family-based treatment models, including Multisystemic Therapy, have demonstrated strong evidence in reducing reoffending and improving family functioning (Borduin et al., 2009; Henggeler et al., 2009).
Family-inclusive approaches can:
• strengthen safety planning and supervision • improve communication and relational stability
• increase children’s capacity to learn appropriate boundaries
• support long-term behavioural change
Effective services therefore prioritise practical coaching, clear guidance, and respectful therapeutic support for caregivers. Families and care networks are not barriers to safety; they are often critical partners in safeguarding and recovery.
Schools: Safety, Support, and Continuity
Schools are frequently the first settings where harmful sexual behaviours become visible. As such, they play a critical role in safeguarding, early identification, and coordinated response.
Guidance for educational settings emphasises the importance of:
• responding promptly and proportionately • ensuring safety and support for all students involved
• working collaboratively with specialist safeguarding and therapeutic services
• maintaining educational engagement wherever possible
When educators have access to clear procedures, specialist advice, and training, they are better equipped to respond consistently and appropriately (NSPCC, 2021; UK Department for Education, 2018). Maintaining a young person’s connection to education, where safe to do so, can also support stability and positive developmental outcomes.
Reducing Stigma While Still Naming Harm
Fear-based responses can contribute to stigma and discourage early disclosure or help-seeking. When harmful sexual behaviours are driven underground, opportunities for timely intervention are reduced.
A public health approach separates the behaviour, which must be addressed clearly and safely, from the child, who is still developing and capable of change. Developmentally informed frameworks emphasise that responses should address harm while supporting the child’s capacity to learn safer behaviour (Hackett, 2014; Smallbone, Marshall & Wortley, 2013).
Language that names harm clearly while maintaining a focus on support and accountability can improve engagement, reduce secrecy, and encourage earlier help-seeking.
Outcomes and Economic Stewardship
Early intervention is not only a safety imperative but also a sound investment in community wellbeing.
Evidence indicates that effective interventions for harmful sexual behaviours can:
• reduce both sexual and non-sexual offending behaviour (Caldwell, 2016; Borduin et al., 2009)
• reduce youth justice involvement (Letourneau & Borduin, 2008)
• improve educational engagement and wellbeing outcomes
• reduce long-term costs across justice, health, and social service systems
Early, coordinated intervention prevents cascading harms and reduces the need for more intensive responses later.
What Works: Elements of a Strong System
Research and practice guidance suggest that effective responses to harmful sexual behaviours require coordinated, system-wide approaches.
Key elements include:
1. Clear referral and assessment pathways
2. Access to specialist clinical assessment and therapy
3. Family-inclusive practice
4. Supported school responses
5. Cross-agency collaboration
6. Workforce training and specialist supervision
7. Ongoing monitoring and evaluation
When these elements operate together, communities are better equipped to identify concerns early, respond proportionately, and support children to develop safer behaviours.
In Tasmania, specialist responses to harmful sexual behaviours are delivered through programs such as SASS’s PAST program, in partnership with Mission Australia. This collaborative model provides comprehensive assessment, therapeutic intervention, family support, and coordination with education and statutory services. By working across the child’s home, school, and community environments, such partnerships operationalise the public health approach described in this article - enabling earlier intervention, clearer safety planning, and more sustainable outcomes.
A Compassionate, Community-Safety-Focused Way Forward
Harmful sexual behaviours among children and young people can be confronting, but they are not inevitable. With early identification, skilled assessment, and coordinated support, the majority of young people can learn safer behaviours and continue their development without further harmful conduct.
A public health response grounded in evidence, compassion, and partnership honours victim-survivors, supports families, strengthens safeguarding systems, and reduces future harm. With coordinated effort and sustained investment communities can respond earlier, intervene more effectively, and build safer outcomes for children, families, and the broader community. This is not only a compassionate approach, it is a practical and evidence-informed pathway to long-term community safety.
