Childhood sexual abuse has been shown to be a significant risk factor for many mental health disorders and problems, and a substantial proportion of children who are victims of sexual abuse develop serious emotional and behavioural difficulties. The literature on child sexual abuse has described almost every psychological problem as being experienced by victims. This bleak picture highlights the critical need for effective interventions for preventing and managing these outcomes. This chapter provides an overview of the interventions currently available. It discusses three broad groupings of treatments in more depth: cognitive-behavioural approaches, individual treatment and group treatment. Cognitive-behavioural approaches are often individual. Perhaps the most widely recognized form of individual treatment is individual psychotherapy. The key elements of abuse-focused psychotherapy are respect, positive regard and an assumption of growth; it takes a phenomenological perspective that focuses on the functionality of symptoms and defences.
