Abstract
Knowing the risk factors of recidivism in sex offenders is important in order to prepare effective preventative interventions and treatment in custody. In this regard, the following paper shows the results of a pilot study carried out in the prisons of central Italy in which 44 sex offenders participated. These participants were given the following tests: Historical Clinical Risk Management-20-version 3 (HCR20v3), Psychopathy Checklist-Revised (PCL-R) and Personal Inventory Dimensional (PID-5). The results show a high positivity in the factors of the sub-scales H (historical factors) and C (clinical factors) of HCR20v3; the average total score of the PCR-L is 16.47, with five subjects who are in the "high psychopathy" range (X ≥ 30); with regard to PID-5, the most positive domain is negative affectivity (56.10%).
