Effects of Child Sexual Abuse

Children and young people who have been sexually abused can suffer a range of psychological and behavioural problems, ranging from mild to severe, both in the short and long term. These effects vary depending upon the circumstances of the abuse, the child’s developmental stage, responses to the child's disclosure and the level of support the child receives in the disclosure's aftermath. Children who are supported and believed when they disclose abuse are less likely to endure long term negative impacts. Learn more about responding to disclosures.

Preventing Child Sexual Abuse


Bravehearts has been working to prevent child sexual abuse for a quarter of a century, dragging this insideous crime out of the shadows and shining a light on the devestating effects it has on victims, families and society.

Before Bravehearts began speaking out about child sexual abuse, it was a taboo subject in the media and society at large. Survivors rarely shared their stories publicly and there was scant support services for those who did. 

Perpetrators of child sexual abuse thrive on silence, secrecy and shame, which is why breaking the silence around this crime is an important key to prevention. 


An essential aspect of preventing child sexual abuse is personal safety education from a young age. Providing children with age-appropriate information around body ownership and the right to be safe allows for these messages to become part of their everyday language and helps build children's self-esteem and resilience, and importantly, teaches them the language they need to speak up if they feel unsafe or are harmed. 

Bravehearts Ditto's Keep Safe Adventure program provides children with these foundational personal safety skills, to date having educated over one million children throughout Australia.

There is much parents and carers can do at home to help build their children's personal safety skills and knowledge too. Bravehearts has some great resources available to get parents and carers started with this - check out the Resources for Parents and Carers section of this site.


Preventing child sexual abuse means believing victims and taking childrens' disclosures of harm seriously. Every adult, especially those who work with or around children, should learn how to respond appropriately to a disclosure so the child feels safe and heard. Likewise, adult survivors need to be supported and feel safe and heard.

When a survivor of child sexual abuse, whether they be a child or an adult, feel safe, seen and heard, their disclosure may lead to the conviction of the perpetrator and the prevention of further harm.
