Prevalence of Sexual Abuse of Children
Despite widespread agreement that sexual abuse of children is a serious problem, disagreement exists about its prevalence. The true scope of child sexual abuse is difficult to measure because of inaccuracies inherent in the methodology of empirical research. For example, incidence figures from child protection agencies include only cases where reports have been substantiated. If a report of child sexual abuse is true but unsubstantiated, it is not included in prevalence estimates. In addition, some cases of child sexual abuse are not reported to authorities and cannot be included in prevalence estimates.
Disclosure of Child Sexual Abuse
Whether disclosure of child sexual abuse is a singular act or an ongoing process has been widely debated in the professional literature and different theories have been posited. For example, disclosure has been theorized to be a continuous process that can be immediate or delayed, accidental or intentional, and certain or marked by recantation, denial and re-disclosure.
One empirical method for studying the disclosure of sexual abuse of children involves surveying adults who experienced sexual abuse as children, and determining their pattern and rate of disclosure. Some retrospective studies of adults who said they were sexually abused as children found that approximately two-thirds did not disclose the abuse during childhood. This finding supports the position that most cases of child sexual abuse (e.g., about 66%) are not immediately reported and are often delayed by months or years.
Influences on Disclosure
Other findings from the cumulative sexual abuse research reveals that disclosure is influenced by the child’s age at the time sexual abuse occurs, and by the availability of a same-aged peer to whom the abuse could be reported. Adults who said they were sexually abused as adolescents reported higher disclosure rates than adults who said they were abused as children. In addition, these adolescents reportedly disclosed the sexual abuse to a friend sooner to its occurrence, while adults who said they were sexually abused as young children, usually disclosed to a parent. These studies also found that children were more likely to disclose sexual abuse if the perpetrator was not a family member and disclosure occurred sooner when sexual abuse was perpetrated by a stranger or non-family member.
Sexual Abuse Research on Abused Children
Another method of studying disclosure rates involves investigating children who are known to have been sexually abused. For research purposes, sexual abuse is typically established by one of three methods: confession by the perpetrator or a guilty plea, criminal conviction for an illegal sexual act, or medical evidence that strongly indicates sexual contact occurred (e.g., sexually transmitted disease).
The sexual abuse research of children who reported abuse during childhood reveals that disclosure occurs at varying rates. For example, one study found less than half of children disclose sexual abuse within 48 hours, while others take up to one year, or more. Another study found three-quarters of children delayed disclosure until one-year after the abuse occurred, and almost 20% did not disclose until more than five years later.
Various reasons have been cited to account for disclosure and failure to disclose. Some tentative evidence indicates that “grooming” a child and establishing a close relationship is associated with delayed disclosure, and that children are quicker to disclose sexual abuse by non-family members. In addition, there is some evidence that children who experience a short duration of sexual abuse delay disclosure or do not report it at all. Finally, an age effect appears related to disclosure with children younger than five being the least likely to disclose abuse during formal interview, even if they had previously disclosed it to someone else.
Studies that examine age differences have found that school-aged children disclose sexual abuse more readily during formal evaluation when compared to pre-school aged children, and disclosures by older children are usually considered more credible than reports made by pre-schoolers. One study found school-age children are more likely to disclose sexual abuse than pre-schoolers. Consistent with this data a national study of Israeli children found that 47.5% of 3- to 6-year-olds reported abuse during formal interview, while 66.7% of 7- to 10-year-olds and 74.1% of 11- to 14-year-olds disclosed their abuse.
Sexual abuse research also indicates that older children are more likely to intentionally disclose the abuse, particularly when asked, while younger children’s disclosures are more likely to be unintentional, involving a spontaneous comment while discussing an unrelated topic or engaged in an innocuous activity. For older children, disclosure to an adult (e.g., parent or teacher) is associated with disclosure during formal interview, and studies have shown that once children disclose abuse they tend to maintain their report during formal examinations.
The national study of Israeli children dealing with both physical and sexual abuse found 65% disclosed abuse during formal interview. Of these children, more than 70% reported sexual abuse, while slightly more than 60% said they were physically abused, indicating that children are more likely to report sexual than physical abuse.
Recantation is another controversial issue discussed in the literature regarding the sexual abuse of children. Some children renounce true allegations, while others retract false claims. At least two hypotheses account for children making an allegation and then denying its veracity. According to one source, studies have found recantation rates ranging from 4% to 27%. The studies with the most reliable finding of sexual abuse have the lowest recantation rates, while studies with the highest rates of recantation involve questionable diagnoses. Underscoring this pattern is the finding that the two studies with the highest rates of recantation include the most unreliable diagnoses of sexual abuse.
One main point of these findings is that a majority of children who undergo a formal interview disclose sexual abuse and do not later recant. Therefore, recantation is not a frequent characteristic of disclosure.
The data outlined above indicates the need for mental health and law enforcement professionals to make careful and detailed evaluations in situations where sexual abuse of children is suspected or alleged.
