Assessment of Recidivism Risk in Sex Offenders: A Pilot Study in Central Italy

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%).

Investigating the Validity Evidence of the Swedish TriPM in High Security Prisoners Using the PCL-R and NEO-FFI

The triarchic model of psychopathy was developed to bridge opposing descriptions of psychopathy by separating the core construct in three domains; boldness, meanness, and disinhibition. The Triarchic Psychopathy Measure (TriPM) operationalizes the model through a 58-item self-report questionnaire. The current study examined the psychometric properties of the Swedish translation by investigating intercorrelations and associations to expert-rated psychopathy, general personality and psychopathy-related traits in male high-security prisoners (n = 191). Psychopathy rated with TriPM and the Psychopathy Checklist Revised (PCL-R) demonstrated expected convergence, as did empathy and impulsivity measures. The Disinhibition and Meanness scales were highly correlated, indicating that the scales might not be adequately differentiated. Nevertheless, the divergent association patterns to other important variables, particularly neuroticism and empathy, also points to meaningful differences. However, the lack of association between Disinhibition and Boldness may put into question if these domains are related at all, especially since there was a lack of similarity in the association patterns with other clinical variables. The influence of antisocial behavior in the TriPM operationalization might amplify the similarities of the Meanness and Disinhibition scales, while diluting the associations between Meanness and Boldness. In conclusion, the Swedish TriPM is effective in measuring the domains of triarchic model in forensic settings, even though a revision of the scales might improve the psychometric properties of the instrument.

A Link between Psychopathy Affect and Instrumentality in Homicide

This study tests the hypothesis that psychopathy is more associated with instrumental homicides than mixed and reactive homicides, and explores relationships between Psychopathy Checklist-Revised (PCL-R) facet/item scores and different forms of homicide: instrumental ( n = 130), mixed ( n = 103), and reactive ( n = 219) homicides. Instrumental homicides scored higher on facet 2 ( p < .01) but scored lower on facet 4 ( p < .1) compared to reactive homicides, whereas no facet scores differed between mixed and reactive homicides. Among the items of facet 2 (affective), remorselessness (item 6), and callousness (item 8) were predictive of instrumental homicide.

Psychopathy and Sexual Aggression: Management Implications

The current study explored the association between psychopathic traits and release suitability decisions and examined the role of Psychopathy Checklist-Revised (PCL-R) and Static-99 in predicting general and sexual recidivism. The sample included 207 adult male sex offenders involved in the long-term follow-up at the Massachusetts Treatment Center for Sexually Dangerous Persons (MTC) in Bridgewater, Massachusetts. Contrary to our expectations, PCL-R Factor 2 (Lifestyle/Antisocial) scores were positively associated with being selected for gradual release, whereas PCL-R Factor 1 (Interpersonal/Affective) scores were not related to parole boards’ decisions. Additionally, the interaction between the two factors was a significant predictor, suggesting that the individuals with more pronounced Factor 1 traits were less likely to be released when their Factor 2 scores were high as well. Although Static-99 scores predicted both contact and non-contact sexual recidivism, psychopathy was not related to reoffending, possibly because offenders with child victims were over-represented in the sample.
