Prevalence of childhood sexual abuse experiences in a community sample of women.

Objective: The study was designed to ascertain the prevalence and nature of sexual abuse in childhood for a community sample of women.

Method: A two-stage design, using questionnaires and face-to-face interviews, was employed, providing information on prevalence rates, types of abuse, ages of victims, relationship to the abuser, and cohort effects.

Results: Nearly one woman in three reported having one or more unwanted sexual experiences before age 16 years. A significant number of these experiences (70%) involved genital contact or more severe abuse, and 12% of those abused were subjected to sexual intercourse. The abusers were usually known to the victim, being family members in 38.3% of cases and acquaintances in another 46.3%. Stranger abuse accounted for 15% of all abuse experiences. Most of the abusers were young men, disclosure of the abuse was infrequent, and only 7% of all abuse was ever officially reported. Prevalence rates showed no urban/rural differences, no cohort effect with subject age, and no age differences in disclosure rates.

Conclusions: Child sexual abuse is common, serious, infrequently reported, and the abuser is usually known to the child. Preadolescent girls are at greatest risk.
