The goal of this study was to compare rates of positive medical findings in a 5-year prospective study of 2384 children, referred for evaluation of possible sexual abuse, with two decades of research. The prospective study summarizes demographic information, clinical history, relationship of perpetrators, nature of abuse, and clinical findings. The study reports on the results by patterns of referral and the medical examination.
There were 2384 children evaluated in a tertiary referral center between 1985 and 1990 for possible sexual abuse. Children were referred after they disclosed sexual abuse, because of behavioral changes or exposure to an abusive environment, and because of possible medical conditions. A total of 96.3% of all children referred for evaluation had a normal medical examination; 95.6% of children reporting abuse were normal, 99.8% who were referred for behavioral changes or exposure to abuse were also normal. Of the 182 children referred for evaluation of medical conditions, 92% were found to be normal at the time of examination by the Child Advocacy Center. The remaining 15/182 (8%) that were found to be abnormal were diagnosed with sexually transmitted diseases, acute or healed genital injuries, and were 17% (15/88) of the total cases found to have medical findings diagnostic of abuse. Interviews of the children indicated that 68% of the girls and 70% of the boys reported severe abuse, defined as penetration of vagina or anus. Penetration was associated with a higher percentage of abnormal findings in girls (6%) compared to 1% of the boys. The relationship of the abuser impacted on the severity of the abuse.
Research indicates that medical, social, and legal professionals have relied too heavily on the medical examination in diagnosing child sexual abuse. History from the child remains the single most important diagnostic feature in coming to the conclusion that a child has been sexually abused. Only 4% of all children referred for medical evaluation of sexual abuse have abnormal examinations at the time of evaluation. Even with a history of severe abuse such as vaginal or anal penetration, the rate of abnormal medical findings is only 5.5%. Biological parents are less likely to engage in severe abuse than parental substitutes, extended family members, or strangers.
本研究的目的是在一项对2384名因可能遭受性虐待而前来接受评估的儿童进行的为期5年的前瞻性研究中,将医学阳性检查结果的发生率与过去二十年的研究结果进行比较。该前瞻性研究总结了人口统计学信息、临床病史、施虐者关系、虐待性质和临床检查结果。该研究按转诊模式和医学检查报告结果。
1985年至1990年间,在一家三级转诊中心对2384名儿童进行了可能遭受性虐待的评估。儿童在披露性虐待情况后、因行为改变或处于虐待环境以及因可能的医疗状况而被转诊。在所有被转诊接受评估的儿童中,96.3%的儿童医学检查结果正常;报告遭受虐待的儿童中95.6%检查结果正常,因行为改变或处于虐待环境而被转诊的儿童中99.8%检查结果也正常。在因医疗状况被转诊接受评估的182名儿童中,儿童权益倡导中心检查时发现92%的儿童检查结果正常。其余15/182(8%)被发现异常的儿童被诊断患有性传播疾病、急性或已愈合的生殖器损伤,占所有被发现有虐待诊断性医学检查结果病例的17%(15/88)。对儿童的访谈表明,68%的女孩和70%的男孩报告遭受了严重虐待,严重虐待定义为阴道或肛门被插入。与1%的男孩相比,女孩中与插入相关的异常检查结果比例更高(6%)。施虐者关系对虐待的严重程度有影响。
研究表明,医学、社会和法律专业人员在诊断儿童性虐待时过于依赖医学检查。在得出儿童遭受性虐待的结论时,儿童的病史仍然是最重要的单一诊断特征。在所有因性虐待接受医学评估的儿童中,只有4%在评估时检查结果异常。即使有阴道或肛门插入等严重虐待史,医学检查结果异常的比例也仅为5.5%。亲生父母比替代父母、大家庭成员或陌生人实施严重虐待的可能性更小。
