Abstract：
Psychopathy has been empirically associated with various forms of antisocial behavior including sexual assault. In fact, the lack of empathy characterizing psychopathic offenders may facilitate the perpetration of more extreme violence. This systematic review aims to explore the relationship between psychopathy traits in male adult sex offenders and the increase in recidivism risk for any type of reoffence, with a special focus on sexual recidivism. From an initial sample of 757 articles related to the topic, only 14 were selected from the current literature at the end of the inclusion process. Each of these assessed the relation between psychopathy traits (measured by PCL-R) and recidivism risk in male sex offenders (age > 18), providing an effect size (quantitative findings). The results of their analysis agree with the currently available literature: the presence of psychopathic traits in sex offenders would seem to correlate with an increased risk of recidivism of general but non-sexual. Furthermore, almost half of the included works highlighted a positive relationship between psychopathy and violent reoffences. However, the limited availability of studies and the unevenness in their results indicate the need to expand future research in this direction.
摘要：
从经验上讲，精神病与包括性侵犯在内的各种形式的反社会行为有关。事实上,缺乏同理心的精神变态罪犯的特点可能会促进更极端的暴力行为的实施。本系统评价旨在探讨成年男性性犯罪者的精神病特征与任何类型犯罪的累犯风险增加之间的关系。特别关注性累犯。从与该主题相关的757篇文章的初始样本中，在纳入过程结束时,从现有文献中只有14人入选.这些都评估了男性性犯罪者（年龄>18岁）的精神病特征（通过PCL-R测量）与累犯风险之间的关系，提供效果大小(定量结果)。他们的分析结果与当前可用的文献一致：性犯罪者中精神病特征的存在似乎与一般但非性行为的累犯风险增加有关。此外，几乎一半的作品强调了精神病和暴力犯罪之间的积极关系。然而,研究的有限可用性和结果的不均匀性表明需要在这个方向上扩展未来的研究。
