Recidivism risk in male adult sex offenders with psychopathic traits assessed by PCL-R: A systematic review

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.
