IntroductionFor child sexual abuse (CSA) victims, disclosure can be helpful or harmful depending on how recipients respond. Despite a growing body of literature examining reactions to disclosure, little is known about the experiences of current CSA victims, particularly those abused by family. ObjectiveWe aimed to describe and explore the initial disclosure experiences of intrafamilial CSA victims, and whether reactions varied based on the type of disclosure recipient. Participants and settingThis study utilized anonymous, archival data from the US-based National Sexual Assault Online Hotline (NSAOH), and focused on a sample of 224 intrafamilial CSA victims who had previously disclosed to one type of recipient. MethodsNSAOH staff summarized children's disclosure experiences via an open-ended survey field. Data were independently coded using the Social Reactions Questionnaire. ResultsNearly three-fourths (73%) of children described receiving a negative reaction to disclosure. Negative reactions included distracting or dismissing the victim (33%), not believing the victim (29%), or retaliating or responding violently following disclosure (10%). Children most frequently disclosed abuse to non-offending family (66%), friends (17%), and formal support providers (12%). Relative to friends and intimate partners, victims were more likely to discuss negative reactions from family (49% v 87%, respectively, Cramer's V = 0.33, p < 0.001). ConclusionsDisclosing to non-offending family may be unproductive and potentially harmful for some children. This study has implications for disclosure-related planning protocols on anonymous hotlines. Findings underscore the importance of educating the public, and parents in particular, about how to respond to CSA disclosures.
