“…Significantly, Bousardt, Addriaan, Hoogendoorn, Noorthoorn, Hummeln and Nijman (2015) found that the incidence of serious physical violence committed by psychiatric inpatients was increased threefold in those who scored high on Urgency, and was nearly two times higher in those with PD (specific types of PD were not examined in this study). Urgency was found to correlate significantly with a composite measure of serious violence in a sample of 100 personality disordered offenders with a history of violent offending (Howard, Khalifa & Duggan, 2014).…”

Recent literature has focused on severity of personality disorder (PD) and a trait-based assessment of PDs in preference to assessment by specific sets of diagnostic criteria. Evidence suggests that emotional impulsiveness, also known as Urgency (Whiteside SP, Lynam DR. The five factor model and impulsivity: using a structural model of personality to understand impulsivity. Personality and Individual Differences,30, 669-689, 2001) might contribute to a broad spectrum of PDs and to overall PD severity. In a sample of 100 forensic psychiatric patients, all men with confirmed PD and a history of serious offending, two hypotheses were tested: first that high Urgency scores would be associated with a broad spectrum of PDs, and with PD severity; and second, that in regression analysis Urgency would uniquely predict measures of PD severity. Results confirmed these hypotheses and are consistent with the idea that emotional impulsiveness/Urgency contributes importantly to overall severity of PD, and in so doing may explain, at least in part, the well-documented link between PD and violence.

“…In the current study, the Dutch SDAS manual of Bousardt is used. As described in this manual, for each of the items a general and peak score can be scored [ 21 ]. In this way, each SDAS item is scored twice, first on the most severe aggressive behaviour (peak), and second on average level of aggressive behaviour.…”

BackgroundMany patients residing in forensic psychiatric centers have difficulties regulating their aggression in an adequate manner. Therefore, they are frequently involved in conflicts. Evidenced-based aggression therapies in forensic psychiatry are scarce, and due to the highly secured environment, it is hard to practice real-life provocations. We have developed a Virtual Reality aggression prevention training (VRAPT), providing safe virtual environments, in which patients can practice controlling their aggressive behaviors in an adequate way. The main objective of this study is to examine whether VRAPT is effective in reducing aggression among forensic psychiatric inpatients.MethodsFour forensic psychiatric centers in the Netherlands are participating in this study. Participants will be randomly assigned to either VRAPT or a waiting list. The two groups will be compared at several different time points: baseline (12 weeks before intervention), pre-intervention, post-intervention and at 12 weeks follow-up. After follow-up measurements are completed, participants from the waiting list will also receive VRAPT. The primary outcome is level of aggressive behavior, consisting of staff-reported and self-reported measures. Secondary outcomes are self-report questionnaires on e.g., anger, impulsivity and aggression.DiscussionTo the best of our knowledge this is the first study to examine the effectiveness of a VR aggression prevention training in forensic psychiatric centers. Further details on the methodological issues are discussed in this paper.Trial registrationDutch Trial Register (NTR, TC = 6340). Retrospectively registered 14–04-2017.

“…Aggressive behavior can also be accompanied by reduced novelty exploration. Novelty exploration is closely associated with aggressive trait features, such as impulsivity and attention deficit [10][11][12][13][14][15] .…”

Previous studies involving mice have demonstrated that a cholesterolenriched diet evokes liver steatosis, dystrophy, inflammation, and aspects of nonalcoholic fatty liver disease (NAFLD). These changes are accompanied by the activation of pro-inflammatory brain and liver molecular pathways, as well as anxiety and depressive-like behaviors. Given previously reported evidence for the neurobiological relationship between the above-mentioned molecular changes and abnormalities in coping with environmental stimuli, such as interactions with other individuals and new environmental contexts, we hypothesized that novelty exploration and aggressive behavior are affected in a mouse NAFLD model. Methods: To test this hypothesis, young female C57BL/6J mice were fed with a regular chow or a diet containing 0.2% cholesterol for 3 weeks. The mice were then assessed for new object and novel cage exploration, and social interaction in a food competition test. Results: We found reduced object exploration in mice on the cholesterol-enriched diet. This reduction was not related to whether the new object was placed in an anxiogenic or non-anxiogenic environment. These changes were accompanied by diminished exploration of the new environment in a novel cage, and delayed approach to food after a period of food deprivation. Mice on the regular chow or cholesterolenriched diet showed no differences in aggressive behavior towards a counter-partner in a food competition test. Food intake and body weight did not differ between the groups, thus, excluding their potential as confounders in the measured behaviors. Conclusions: We conclude that a diet enriched with cholesterol reduces novelty exploration irrespective of the anxiogenic level of the environment and does not induce aggressive behavior in female mice.
