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 (n = 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.

在英国社区样本中对不雅儿童图像有信念的个人的犯罪率降低。

尽管他们在所有确定的性犯罪者中所占的比例相对较小，但人们越来越关注与网上不雅儿童图像（IIOC）有关的犯罪的个人。这项研究调查了参与英国社区干预的仅IIOC（n = 584，84.6％）和IIOC接触混合（n = 106，15.4％）罪犯的再犯罪率以及风险和心理的预测效度评估结果。经过13年的平均随访，任何再次定罪的经证实的再犯罪率为24.8％，对性犯罪的再犯罪率为12.6％。比率差异很大，混合组接受任何定罪的可能性高2倍，而接受性定罪的可能性高3倍。仅IIOC小组中只有2.7％被判犯有随后的接触罪。发现先前的一般犯罪可以显着预测一般定罪，而先前的性犯罪则可以显着预测性定罪，尽管预测力较弱。对治疗“领域”的可靠改变不能预示一般或性定罪。虽然较低的定罪率不能将IIOC的使用严重性降到最低，但这些发现凸显了需要对经过验证和自我报告的违规历史进行全面评估以做出合理的风险决策，以及需要更长的随访时间以及在检测到的结果与比较结果之间进行较大样本比较的需求。未检测到的IIOC用户。这些发现还引发了人们对与治疗相关的性质和效率的疑问，在该人群中，重新定罪率似乎相对较低。（PsycINFO数据库记录（c）2019 APA，
