The psychological problems and difficulties experienced by adults who report having been sexually abused in childhood are reviewed. These long-term effects include damage to the victims' emotional reactions and self-perceptions, relationship problems, problems with sexuality and difficulties in social functioning. Common presenting problems of victims of childhood sexual abuse (CSA) are described. Also discussed are the characteristics of incestuous abuse in terms of the victim, the abusive relationship and its termination; the contributions of the various aspects of CSA to the psychological impact of such abuse; and psychodynamic explanations of the development of long-term effects. The bulk of the published material regarding the long-term effects of CSA refers to female victims only, and this 'bias' is reflected in the review.
