The empirical basis for the child sexual abuse accommodation syndrome (CSAAS), a theoretical model that posits that sexually abused children frequently display secrecy, tentative disclosures, and retractions of abuse statements was reviewed. Two data sources were evaluated: retrospective studies of adults' reports of having been abused as children and concurrent or chart-review studies of children undergoing evaluation or treatment for sexual abuse. The evidence indicates that the majority of abused children do not reveal abuse during childhood. However, the evidence fails to support the notion that denials, tentative disclosures, and recantations characterize the disclosure patterns of children with validated histories of sexual abuse. These results are discussed in terms of their implications governing the admissibility of expert testimony on CSAAS.
Although it is widely acknowledged that the sexual assault of children is a major societal concern, it is not known how many children are victims of sexual abuse in the United States . There are two major reasons for this lack of data. First, present estimates of the incidence of child sexual abuse (CSA) are primarily based on reports received and validated by child protection agencies. These figures, however, do not reflect the number of unreported cases or the number of cases reported to other types of agencies (e.g., sheriff's offices) and professionals (e.g., mental health diversion programs). Second, the accuracy of diagnosis of CSA is often difficult because definitive medical or physical evidence is lacking or inconclusive in the vast majority of cases (Bays &
