At present there is no consensus of opinion about the short-term or long-term effects of child sexual abuse, although there is a growing body of literature on the subject. Definitions of what constitutes child sexual abuse vary enormously and, even where agreed, include a wide range of behaviours. Most clinical reports are retrospective in nature and based on self-report. Many authors agree that effects can be classified into four general areas, however, emotional/psychological; sexual adjustment; interpersonal relationships; and social functioning. There are considerable implications for treatment of those who have been abused and for the protection of their children.
