Preventing in-prison violence and maintaining a safe environment is an important goal within prison settings. Screening for violence risk may provide a valuable addition to reach this goal. Within the Dutch prison system, the Risk Screener Violence (RS-V) has become an important new element in overall risk management. Prior research shows that RS-V scores are a sound predictor of institutional violence and aggression of incarcerated persons. Whereas previous studies predominantly analyzed retrospective file-based data, the present study includes RS-Vs rated by prison employees in real-life prison practice shortly after implementation. The RS-Vs of 956 detained individuals from 25 Dutch prisons were analyzed. Disciplinary reports were consulted to measure violent and aggressive incidents during 4 months after the screening. In addition, detention duration (length of stay in prison before the screening) was included as an additional variable. Results of the present prison practice study show good predictive values of the RS-V ratings for violent and aggressive incidents during prison stay. The predictive validity was similar for prisoner-to-prisoner assault as well as prisoner-to-staff assault. In addition, the predictive validity of the RS-V scores did not differ between individuals with a longer detention duration versus individuals with a shorter detention duration. This multisite prison practice study is an important step in the further validation of the RS-V and shows that the RS-V is a valuable tool in determining who is more likely to show institutional violence. Nonetheless, it remains important to continually monitor the implementation and correct application of the RS-V in prison practice.

Psychopaths are suggested to be more likely to favor utilitarian outcomes over non-utilitarian (i.e., deontological) choices. Here we re-test this hypothesis and investigate whether oxytocin, a hormone associated with empathy, can counter this utilitarian effect. Forensic psychopathic patients and non-psychopathic controls participated in a sacrificial moral decision-making paradigm. Psychopathic patients performed the task in a double-blind cross-over placebo-controlled oxytocin administration paradigm. We found no evidence for psychopathic patients to act more utilitarian (or sacrificial) or any effect of oxytocin administration. Psychopathic traits within the control group, particularly traits associated with lack of empathy and failure to consider consequences, were however associated with more utilitarian choices, but only when these actions were low in emotion. In contrast, psychopathy severity in psychopathic patients, particularly impulsivity-related traits, predicts deontological choices, but only in highly emotional actions. Thus, although psychopathic traits do predict utilitarianism when emotional investment is low, this is not the case in full-blown psychopathy. Instead, there is a link between impulsivity and deontological choices in psychopathic patients, but only when emotional investment is high, and self-interest is not at stake. These preliminary results are discussed to whether utilitarian outcomes align with the personal goals of psychopathic individuals.

Introduction Physical and verbal violence toward staff or other detained individuals is a reoccurring problem within correctional facilities. Screening for violence risk within the prison setting could provide a valuable first step in the prevention of institutional violence. The brief and compact Risk Screener Violence (RS-V) has shown to be an efficient new method for assessing concerns regarding post-release violent offending for incarcerated persons. This study aimed to find out whether the RS-V is also able to predict future violent and aggressive incidents during imprisonment. Methods The predictive validity of the RS-V for future violent and aggressive incidents during a follow-up time of 4 months within prison was analyzed, using a file-based design. Violent incidents toward staff and other inmates (physical violence and violent threats), other aggressive incidents (aggression toward objects and verbal disruptive behavior), and both categories combined, were included as outcome measures based on disciplinary reports. Results The RS-V showed medium to large predictive values for both violent and aggressive behavior during prison stay. In particular, good predictive values of the RS-V were found for violence toward prison staff. Discussion This study shows that, besides post-release violent recidivism, the RS-V is able to accurately predict future violent and aggressive incidents during prison stay. By correctly differentiating between low concern and high concern individuals, the RS-V aims to contribute to more personalized interventions and risk management and, subsequently, to improved prison safety. Future studies using prospective prison practice data are needed to further support the validity of the RS-V regarding institutional violence.

Within the prison system, it is often not feasible to administer comprehensive risk assessment for all incarcerated persons because of limited time and resources. To enhance prison safety and facilitate the structured evaluation of concerns about violence risk for all individuals, the Risk Screener Violence (RS-V) was developed. The goal of this study was to evaluate whether the RS-V ( N = 571) is able to retrospectively predict postrelease violent (re)offending for males (81%) and females (19%). The RS-V was scored with excellent interrater reliability and demonstrated medium to large predictive validity for all follow-up periods. Surprisingly, the predictive validity for females was even stronger than for males. This study demonstrates that the RS-V offers a promising new method for the efficient screening of concerns regarding violent behavior among incarcerated males and females. Further prospective studies in prison practice will have to consolidate these findings.

COVID-19 caused a great burden on the healthcare system and led to lockdown measures across the globe. These measures are likely to influence crime rates, but a comprehensive overview on the impact of COVID-19 on crime rates is lacking. The aim of the current study was to systematically review evidence on the impact of COVID-19 measures on crime rates across the globe. We conducted a systematic search in several databases to identify eligible studies up until 6–12-2021. A total of 46 studies were identified, reporting on 99 crime rates about robberies (n = 12), property crime (n = 15), drug crime (n = 5), fraud (n = 5), physical violence (n = 15), sexual violence (n = 11), homicides (n = 12), cybercrime (n = 3), domestic violence (n = 3), intimate partner violence (n = 14), and other crimes (n = 4). Overall, studies showed that most types of crime temporarily declined during COVID-19 measures. Homicides and cybercrime were an exception to this rule and did not show significant changes following COVID-19 restrictions. Studies on domestic violence often found increased crime rates, and this was particularly true for studies based on call data rather than crime records. Studies on intimate partner violence reported mixed results. We found an immediate impact of COVID-19 restrictions on almost all crime rates except for homicides, cybercrimes and intimate partner violence.

Introduction The Violent Extremism Risk Assessment - Version 2 Revised (VERA-2R) is an evidence-based structured professional judgement (SPJ) tool for ideologically motivated violence. Use of the tool can help professionals in risk assessment and risk management of suspected and convicted terrorists and violent extremists at different stages within the criminal process. It is important that the tool leads to reliable and valid risk assessments. Methods The present study aimed to establish the reliability of the VERA-2R, focusing on the interrater- and intrarater reliability. Trained researchers assessed the interrater- and intrarater reliability, respectively in 30 and 33 cases of Dutch convicted terrorist offenders, on the basis of extensive judicial files. Results In general, the average amount of agreement on the indicators and structured risk judgements can be classified as good to excellent, for both the interrater- and intra-rater reliability. However, six indicators were found to have low reliability. Above clarifying the reliability of the VERA-2R, this study also showed how the interrater- and intrarater reliability of a SPJ tool can be investigated with trained assessors based on judicial files. This can be of added value, because existing reliability studies often use case vignettes, have a small sample size and/or do not include a stringent training program. Discussion With this research, we can make more substantiated recommendations on how the VERA-2R can be improved. This could lead to more accurate risk assessments and risk management strategies. However, in order to develop a more reliable and valid VERA-2R instrument, the remaining psychometric properties must also be investigated and published. That will be discussed in a future article.

Introduction Violent extremism risk assessments of individuals suspected or convicted of terrorism are relevant for legal decisions, in prison and probation settings, and in inter-professional risk collaboration. These risk assessment reports by professionals should be applicable to and usable for the different judicial contexts. Informal and formal clinical practice evaluations, in the form of practitioners feedback and standardised evaluation of professional violent extremism risk reports are needed to gain insight in the use and quality of violent extremism risk assessments. Methods In this study we examined how forensic professionals from three different countries (Sweden, Belgium and the Netherlands) use the VERA-2R in different judicial contexts. We also investigated which organizational aspects are important for the use of the VERA-2R. We focused on the perspective of the forensic professionals and their judicial organisations. We did a standardised survey among 86 VERA-2R trained professionals and a standardised interview with 20 executives and managers of organizations working with the VERA-2R. Results This study showed that professionals find the VERA-2R useful for structuring information and speaking a common risk language. However, using the VERA-2R comes with a variety of challenges, both on the professional and organisational level. VERA-2R trained professionals had few opportunities to use the instrument and when they did, they were not always offered regular supervision, intervision and booster training. Also, organisational issues in collaboration between judicial partner organisations and the lack of risk transfer information to professionals came to light. Discussion More research on the topic of risk transfer is needed. Policy implications are advised, for example the development of booster trainings, more organizational support, regulations on re-assessments, providing expertise and knowledge to indirect stakeholders and clear writing guidelines.

Introduction Terrorism and violent extremism are major social threats worldwide and are committed not only by men but also by women. Previous research has shown indications of psychopathology, among other personal and contextual factors, as a potential risk factor for perpetrating terrorist and violent extremist crimes. Despite the fact that women have engaged in acts of terrorism and violent extremism throughout history, the vast majority of literature on psychopathology so far has been mainly focused on men with terrorist and violent extremist behavior. As women's engagement in terrorism and violent extremism is increasing, and gender differences in psychopathology in offenders of terrorism or violent extremism may exist based on empirical evidence for such differences in offenders of violence, gender-informed research into psychopathology as a potential risk factor for offending is of pivotal importance for improving the effectiveness of counter-terrorism interventions. The present systematic review was designed to examine what empirical knowledge exists on the presence and potential contributing role of psychopathology in female perpetrators of terrorism or violent extremism. Methods A literature search was conducted to identify primary source studies in PsycINFO, PubMed, Embase, Web of Science, and Sociological Abstracts. ASReview as an artificial intelligence software was used to screen references. Results In total, eight studies were included, of which only two studies distinguished prevalence rates and types of psychopathology separately for women, indicating personality disorder as most common. All four out of the eight studies that reported on the relationship between psychopathology and terrorism and violent extremism assumed psychopathology to be a contributing factor in engaging in terrorist or violent extremist acts. However, none of these four studies reported on potentially present female-specific mechanisms of the role of psychopathology in offenses. Discussion The present systematic review draws the striking conclusion that there is a lack of clearly described empirical studies on psychopathology in female perpetrators of terrorism and violent extremism and emphasizes the importance of more future empirically based inquiries on this topic by the forensic psychiatric field.
