Childhood sexual abuse has multiple negative impacts across the lifespan. In the U.S. alone, an estimated one out of three females and one out of five males will be sexually victimized before they turn 18 years old. Prior sexual abuse can often manifest through sexualized behaviors and mental health disorders in children and adolescents. Children who have been sexually or physically abused have been found to suffer from posttraumatic stress disorder (PTSD) and attention deficit /hyperactivity disorder (ADHD). Children who have experienced sexual abuse are also frequently diagnosed with anxiety disorders, psychotic disorders, mood disorders, disruptive disorders, depression, suicidal ideation and suicide attempts. Children who have experienced sexual abuse may also victimize other children. Because of the extensive trauma seen in children and adolescents who have been sexually abused, effective treatment is paramount for reducing behaviors that place the individuals, their families, and the wider community at risk for ongoing trauma.
