Background

Data from sex offender treatment programmes (SOTP) on the re-offending of convicted sex offenders from the prison service in England and Wales was recently reviewed and found to be associated with no change in sexual reoffending. While this result is at variance with a number of other reviews it does give rise to concern as most programmes for individuals with intellectual disabilities adopt similar treatment methods. It is therefore important to consider the treatment outcomes for this client group by conducting a meta-analysis to examine treatment effects.

Method

A systematic search of PsychINFO, EMBASE, MEDLINE and CINAHL was conducted in February 2019 using specific inclusion and exclusion criteria. Eighteen papers were identified, and their quality was assessed using a risk of bias framework. Scores on cognitive distortions, sexual knowledge and victim empathy measures as well as reports of further sexually abusive behaviour were pooled together to run a meta-analysis which yielded effect sizes for each outcome.

Results

A large treatment effect was found for reducing cognitive distortions and increasing victim empathy, with a moderate effect found for improvements in sexual knowledge. This meta-analysis also found that 11.5% of individuals with intellectual disabilities who have completed these programmes will go on to display further sexually abusive behaviours.

Conclusions

The findings suggest that cognitive distortions are significantly reduced following treatment, there are also significant improvements in sexual knowledge and victim empathy. A rate of 11.5% for further reported sexually abusive behaviour during follow up periods was found, which is higher than the rate found for mainstream SOTP completers. Problems regarding the recording of sexually abusive behaviour are considered.

基于认知行为疗法的团体干预对智障和性犯罪史男性的有效性：荟萃分析

背景

最近审查了来自性犯罪者治疗计划 (SOTP) 的关于英格兰和威尔士监狱服务中已定罪的性犯罪者再犯罪的数据，发现这些数据与性犯罪再犯罪没有变化有关。虽然这一结果与许多其他评论不一致，但它确实引起了人们的关注，因为大多数针对智障人士的项目都采用了类似的治疗方法。因此，重要的是通过进行荟萃分析来检查治疗效果来考虑该客户群体的治疗结果。

方法

2019 年 2 月使用特定的纳入和排除标准对 PsychINFO、EMBASE、MEDLINE 和 CINAHL 进行了系统搜索。确定了 18 篇论文，并使用偏倚风险框架评估了它们的质量。将认知扭曲、性知识和受害者同理心测量的得分以及进一步性虐待行为的报告汇总在一起，进行荟萃分析，得出每个结果的效果大小。

结果

发现在减少认知扭曲和增加受害者同理心方面有很大的治疗效果，对提高性知识有中等效果。这项荟萃分析还发现，11.5% 完成这些计划的智障人士将继续表现出进一步的性虐待行为。

结论

研究结果表明，治疗后认知扭曲显着减少，性知识和受害者同理心也有显着改善。发现在随访期间进一步报告性虐待行为的比率为 11.5%，高于主流 SOTP 完成者的比率。考虑有关记录性虐待行为的问题。
