Although they remain a relatively small proportion of all identified sex offenders, there is increasing concern about individuals with offenses relating to indecent images of children (IIOC) online. This study examined the reoffending rates of a sample of IIOC-only ( = 584, 84.6%) and mixed IIOC-contact (n = 106, 15.4%) offenders who participated in a U.K. community intervention and the predictive validity of risk and psychological assessment outcomes. Proven reoffending rates were 24.8% for any reconviction and 12.6% for sexual reconvictions after a 13-year average follow-up. Rates differed significantly, with the mixed group 2 times more likely to receive any reconviction and 3 times more likely to receive a sexual reconviction. Only 2.7% of the IIOC-only group was convicted of a subsequent contact offense. Prior general offenses were found to be significantly predictive of general reconviction and prior sexual convictions were significantly predictive of sexual convictions, albeit with weak predictive power. Reliable change on treatment "domains" was not predictive of either general or sexual reconvictions. While lower reconviction rates do not minimize the seriousness of IIOC use, these findings highlight the need for comprehensive assessment of proven and self-reported offending history to make sound risk decisions and the need for larger samples with longer follow-ups and comparisons between detected and undetected IIOC users. The findings also raise questions about the nature and efficiencies related to treatment for a population in which rates of reconviction appear to be relatively low.

虽然他们在所有被识别的性犯罪者中仍然只占相对较小的比例,但人们越来越关注与儿童不雅图像(IIOC)在线相关的犯罪者。本研究考察了一组仅涉及 IIOC(n=584,84.6%)和混合 IIOC-接触(n=106,15.4%)罪犯的再犯罪率,这些罪犯参与了英国社区干预,以及风险和心理评估结果的预测有效性。在 13 年的平均随访后,任何重罪犯的实际再犯罪率为 24.8%,性罪犯的再犯罪率为 12.6%。比率差异显著,混合组的任何重罪犯的可能性是对照组的两倍,性重罪犯的可能性是对照组的三倍。仅 2.7%的仅涉及 IIOC 组被判犯有后续接触罪。先前的一般犯罪被发现与一般重罪犯有显著的预测关系,而先前的性犯罪与性犯罪有显著的预测关系,尽管预测能力较弱。治疗“领域”的可靠变化与一般或性重罪犯无关。虽然较低的再犯罪率并不能减轻 IIOC 使用的严重性,但这些发现强调了需要全面评估已证实和自我报告的犯罪史,以做出明智的风险决策,需要更大的样本量,更长的随访时间,以及对已检测和未检测到的 IIOC 用户进行比较。这些发现还引发了一些关于性质和与治疗相关的效率的问题,因为再犯罪率似乎相对较低。(PsycINFO 数据库记录(c)2019 APA,保留所有权利)。
