This paper (Part I) and its companion paper (Part II) provide an overview of the primary prevention of child maltreatment. Part I reviews the effectiveness of interventions aimed at the primary prevention of child physical abuse and neglect. Prospective controlled trials published between January 1979 and May 1993 were systematically identified. The quality of each study was determined using criteria which assessed methodological rigor. Interventions aimed at the prevention of physical abuse and neglect were classified into six main categories within the broad group of perinatal and early childhood programs. While many of these programs did not show a reduction in physical abuse or neglect, there is evidence that extended home visitation can prevent physical abuse and neglect among disadvantaged families.

This paper (Part II) and the previous paper (Part I) provide an overview of the primary prevention of child maltreatment. Part II focuses on the effectiveness of interventions aimed at the primary prevention of child sexual abuse. It includes prospective controlled trials published between January 1979 and May 1993. These studies were systematically identified and the quality of each trial was determined using criteria which assessed methodological rigor. Interventions aimed at the prevention of sexual abuse were classified into eight main categories based on the method of intervention. All programs had education as the primary focus. There is evidence that educational programs can improve safety skills and knowledge of children about sexual abuse but no study has produced data that education actually reduces the occurrence of sexual abuse.
