- The aim of this study was to compare antisocial and family-only intimate partner violence (IPV) perpetrators in terms of IPV recidivism rates, type of recidivism crime, and time to recidivism. A total sample of 628 perpetrators was categorized as antisocial (n = 327) or family-only (n = 301) based on general criminality. Results demonstrated that antisocial perpetrators recidivated to a larger extent than family-only perpetrators (27.2% vs. 12.9%). Antisocial perpetrators were more prone to recidivate in both physical and nonphysical violence. Of the perpetrators who recidivated, the majority did so within the first year after their index crime. However, antisocial perpetrators recidivated more than family-only perpetrators after the first year. Key findings consisted of the subtypes’ differing propensity to reoffend and their different critical time periods for recidivism. These findings suggest the need for different risk management strategies depending on perpetrator subtype to prevent future violence.

- Retrospective risk assessments based on the HCR-20 violence risk assessment scheme were performed on 63 female patients and 85 male patients at two special forensic psychiatric hospitals. The aim was to compare risk factors for violence in mentally disordered women with their male counterparts, and to study to what extent the HCR-20, which is mainly based on research on men, can be used in a female forensic psychiatric population. The results show that the HCR-20 displays very similar risk factors for violence in women as in men, but the nature of violence is somewhat different between the sexes. Implications of the findings are discussed.

- Purpose. This study focused on whether institutional violence in a maximum-security correctional institution could be prevented using comprehensive risk assessments followed by adequate risk management. And, could this be shown by a decrease in risk factors for violence according to the HCR-20 Risk Assessment Scheme in the study group? Methods. Offenders with a history of violent criminality were subject to real-life assessments using the HCR-20 Risk Assessment Scheme. The assessments were followed by discussions with members of staff, in which risk management strategies were designed. Thus, the members of staff were fully aware of every inmate's personality characteristics (e.g. psychiatric diagnoses), what risk factors for violence they displayed, and how best to manage those risk factors. With the aim of evaluating the possible effects of our interventions, approximately one third of the study group was reassessed after a mean of 12 months. Results. The follow-up showed no significant decrease in important risk factors for violence in the study group. However, the number of violent incidents showed a remarkable decrease during the study period. Conclusions. Not being able to reduce important risk factors for violence does not necessarily mean that one cannot decrease the risk for, or the incidence of, violence. This study indicates that proper and adequate risk management, using the best protective factors available, can reduce violence even though important risk factors cannot be decreased. The study also supports the theoretical assumption that changes in risk factors are more possible in some populations (e.g. general psychiatric) than in others (e.g. correctional) depending on the nature of the study group and the risk factors that are at hand (e.g. dynamic vs. static). This seems to be important to bear in mind when performing evaluation research using risk assessment instruments.

Tidskriftsartikel (refereegranskat)abstract
- The HCR-20 and the PCL:SV were used in a prospective study of 41 long-term sentenced offenders in two correctional, maximum-security institutions. The aim was to test the validity of these instruments in the prediction of institutional violence. All assessments were made by a comprehensive examination of the offenders' files, completed with clinical interviews ranging from 1 to 3 hours. The mean follow-up time was 8 months. Our results show high predictive validity for the HCR-20's clinical and risk management items, but for almost none of its historical items. The results suggest that violence inside correctional institutions can be predicted with a certain degree of validity by using the HCR-20 and the PCL:SV, even within a selective 'high-risk' group of offenders such as that under study here.

Tidskriftsartikel (refereegranskat)abstract
- 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.
