By some accounts, sex offenders with mental retardation commit sex offenses against children because the offenders lack sexual knowledge or are socially and intellectually immature rather than because of sexually deviant interests. By other accounts, these offenders exhibit pedophilic sexual interests. In this study, phallometrically determined sexual interests, recidivism, and choices of victims of 69 sex offenders with mental retardation are examined and compared with those of 69 sex offenders of average or higher IQ. Consistent with hypotheses, sex offenders with mental retardation exhibit more deviant preferences for prepubertal children, male children, and young children than do the comparison offenders. They are also more likely to have had a prepubertal victim, a prepubertal male victim, and a very young victim. They are no more likely than the comparison offenders to exhibit preferences for extremely coercive sex with children or to exhibit deviant adult activity preferences, nor are they more likely to recidivate violently. Results support the idea that pedophilia is a disorder of neurodevelopment and point to the importance of risk assessments that include assessing sexual preferences among sex offenders with mental retardation.
据一些说法，患有智力障碍的性犯罪者对儿童实施性犯罪，是因为他们缺乏性知识，或者在社交和智力方面不成熟，而不是因为有性变态的兴趣。据其他说法，这些犯罪者表现出恋童癖的性兴趣。在本研究中，对69名患有智力障碍的性犯罪者通过阴茎体积描记法测定的性兴趣、再犯情况和受害者选择进行了研究，并与69名智商平均或更高的性犯罪者进行了比较。与假设一致，患有智力障碍的性犯罪者比对照犯罪者对青春期前儿童、男童和幼儿表现出更多异常偏好。他们也更有可能有青春期前的受害者、青春期前的男性受害者和非常年幼的受害者。他们与对照犯罪者相比，并不更倾向于对儿童进行极端强迫性行为或表现出异常的成人活动偏好，也没有更高的暴力再犯可能性。结果支持了恋童癖是一种神经发育障碍的观点，并指出了风险评估的重要性，其中包括评估患有智力障碍的性犯罪者的性偏好。
