Abstract [en]

This study evaluated the structural reliability, construct-related validity, and cultural validity generalization of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a sample of more than 560 male and female Swedish forensic psychiatric treatment patients, forensic evaluation patients, and criminal offenders. Structural reliability was excellent for most indices. PCL:SV scores were higher for males than females for total and Part 1 scores (interpersonal/affective features) but not for Part 2 (behavioral features). With some exceptions, PCL:SV scores were meaningfully related to aggression to others, a measure of risk for violence, substance use problems, personality disorder (positive), and psychosis (negative). Correlations between PCL:SV and aggression were larger for females than males, although the difference was smaller when personality disorder was held constant. The structural reliability and pattern of validity coefficients were comparable in these Swedish samples to other non-North American samples. Implications for the cross-cultural manifestation and correlates of psychopathy are discussed.

Abstract [en]

When assessing the risk of violence, increasing interest has been shown in bringing science and practice closer together. Moving from clinical intuition in the first generation of risk assessment via actuarial scales in the second generation to the structured professional judgments where risk assessments are today produces better, more valid results when assessing the risk of violence. One of the best predictors of violence is gender. Approximately 10% of the violent criminality can be attributed to women; even so, it is increasing, especially among young women. It is therefore important to examine risk assessments from a gender perspective. Another important factor when assessing the risk of violence is psychopathy and there are indications that there might be gender differences in this diagnosis. Thus, a special interest has been focused on psychopathy in this thesis. The purpose with this work is to explore the similarities and differences in assessing risk for violence in male and female mentally disordered offenders, while the overall aim is to validate the violence risk assessment instrument HCR-20 for Swedish offender populations. The risk assessments for all six studies in this thesis were made by trained personnel using the HCR-20 instrument, where psychopathy was diagnosed with the screening version of the Psychopathy Checklist (PCL:SV). The study populations were both male and female mentally disordered offenders in either the correctional or the forensic setting.

The findings show that both the validity and the reliability of the HCR-20 and the PCL:SV were good and the clinical and risk management subscales were found to have better predictive validity than the historical scale. Another finding was that there were more similarities than differences between genders in the HCR-20, while the opposite applied to the PCL:SV, where the antisocial behavior was performed in a different manner. Moreover, it was found that the gender of the assessor might be a factor to take into account when assessing the risk of violence in women, where the recommendation was that at least one assessor should be female. The conclusions were that the HCR-20 and the PCL:SV can be used In Swedish offender populations with valid results. For female offenders, there are differences in the antisocial behavior that is assessed in order to diagnose psychopathy and these differences tend to underestimate psychopathy among female offenders. Furthermore, the gender of the assessor might be of greater importance than has previously been realized. The overall conclusion was that this thesis supports the structural professional judgment method of making risk assessments in order to prevent violence in the community.
