After defining incest, the characteristics of incestuous families and their members are profiled. A listing of the signs and symptoms of child sexual abuse covers the victim's physical symptoms and behavioral signs by age group (preschoolers, school-age children, and adolescents).

Among the suggestions for preventing child sexual abuse and incest are to teach children the difference between 'good' touching and 'bad' touching by others, how to handle encounters with strangers, and where to go for safety on routes frequently used by the children. Parents can aid prevention through the careful selection of those who care for their children and by encouraging their children to talk about any experiences that frighten them or make them feel uncomfortable. Suggestions are also offered for what an adult should do if sexual abuse or incest is suspected.
