This study examines how key demographic variables and specific child sexual assault (CSA) incident characteristics were related to whether adolescents reported that they had told anyone about an alleged sexual assault. The study also investigates whether there were differences in the correlates of CSA disclosure as a function of gender and race/ethnicity. A national household probability sample of 4,023 adolescents was interviewed by telephone about childhood experiences, including CSA history. Significant gender and racial/ethnic differences were obtained in rates of CSA disclosure: Sexually abused boys and African American youth were less likely to report telling anyone they had been sexually abused. Separate regression models examining correlates of CSA disclosure yielded differences as a function of gender and race/ethnicity.
