Expression level of myocardial enzymes in patients with schizophrenia: Predictive value in the occurrence of violence

BACKGROUND Schizophrenic patients are prone to violence, frequent recurrence, and difficult to predict. Emotional and behavioral abnormalities during the onset of the disease, resulting in active myocardial enzyme spectrum. AIM To explored the expression level of myocardial enzymes in patients with schizophrenia and its predictive value in the occurrence of violence. METHODS A total of 288 patients with schizophrenia in our hospital from February 2023 to January 2024 were selected as the research object, and 100 healthy people were selected as the control group. Participants’ information, clinical data, and laboratory examination data were collected. According to Modified Overt Aggression Scale score, patients were further divided into the violent (123 cases) and non-violent group (165 cases). RESULTS The comparative analysis revealed significant differences in serum myocardial enzyme levels between patients with schizophrenia and healthy individuals. In the schizophrenia group, the violent and non-violent groups also exhibited different levels of serum myocardial enzymes. The levels of myocardial enzymes in the non-violent group were lower than those in the violent group, and the patients in the latter also displayed aggressive behavior in the past. CONCLUSION Previous aggressive behavior and the level of myocardial enzymes are of great significance for the diagnosis and prognosis analysis of violent behavior in patients with schizophrenia. By detecting changes in these indicators, we can gain a more comprehensive understanding of a patient’s condition and treatment.

Risk factors for violent crime in patients with schizophrenia: a retrospective study.

The relationship between schizophrenia and violence is heterogeneous and complex. The aim of this study was to explore the characteristics and the potential risk factors for violence crime in patients with schizophrenia. We conducted a retrospective case-control study at the Judicial Psychiatric Identification Unit of Xiangya Second Hospital of Central South University from January 1, 2013 to December 31, 2016. The case group included violent offenders diagnosed with schizophrenia, while the control group comprised non-violent individuals with the same diagnosis. There were 308 individuals in the violent group [subdivided into the homicide group (n=155) and the intentional injury group (n=153)] and 139 individuals in the non-violent group. A risk model showed that a history of violence (odds ratio (OR) = 2.88, 95% CI [1.79-4.64]), persecutory delusions (OR = 2.57, 95% CI [1.63-4.06]), regular treatment in the previous four weeks (OR = 0.29, 95% CI [0.16-0.51]) and insight (OR = 0.30, 95% CI [0.14-0.62]) were independently associated with violence. This study provided useful clinical information to identify risk factors for violence and develop better strategic programs to manage violence in patients with schizophrenia.

The results of Wisconsin Card Sorting Test in patients under forensic observation of their mental states in violent and non-violent subgroups

IntroductionPrevious studies showed, that reduced executive function can be associated with antisocial and aggressive behavior. For the measurement of executive functions numerous standardized neuropsychological tests are available.ObjectivesWe thought to compare the results of an executive function examination with Wisconsin Card Sorting Test (WCST) of patients observed at the Semmelweis University’s Department of Psychiatry and Psychotherapy to normative data from published database. We also performed a subgroup analysis between the violent and non-violent groups of the patients.MethodsAfter data clearance our dataset consisted of 20 patients, who were divided into two groups based on whether the crime they committed before their admission was violent according to the Cornell scale.The analyzed parameters were the number of perseverative errors, the percentage of perseverative errors, and the number of completed categories. For comparison, the data bank from the 1993 edition of the WCST manual as normative data was used. The deviation from the healthy average for all three parameters was compared between the violent and non-violent groups using a two-sample T-test.ResultsThere was significant difference between the patient and normal populations in all the 3 analyzed WCST parameters: the mean difference was 9,37+2,764, (p=0,0008) in the number of perseverative errors, 14,04+2,21 (p<0,0001) in the percentage of perseverative errors and -2,39+0,34 (p<0,0001) in the number of completed categories (Table 1). Table 1:The difference between the average scores of healthy individuals grouped by age (from the 1993 WCST manual) and the scores of the patients.

However, our results were in line with previous similar research in the forensic psychiatric population (though not under forensic mental state observation) regarding the significant deviations in two examined WCST parameters when compared to normative data. Additionally our study did not find significant difference between the violent and non-violent subgroups of the patients.Disclosure of InterestNone Declared

Examining real-world legitimization of cross-party violence through two explanatory frameworks: Affective polarization and low group efficacy

Cross-party violence – violence between opposing partisans – is a growing concern worldwide. Understanding the predictors of the legitimization of violence against political opponents is thus becoming a vital goal. In this work, we propose two potential explanatory frameworks: affective polarization and low non-violent group efficacy. The first reflects an affective motivation to harm the out-party, while the latter reflects an instrumental motivation to deploy violence. Furthermore, while the former is frequently suggested in scholarly work as a cause for such violence, it has so far been backed only by limited empirical support. On the other hand, the latter is hardly examined in the context of interactions between opposing partisans. We tested the relationship of the two explanatory frameworks with the legitimization of cross-party violence using public opinion surveys in two real-world contexts: in 2020, in Israel (N = 500) and in the US (N = 631). Results from a regression analysis provide support for the instrumental explanation but not for the affective one. We discuss the theoretical implications of our findings for the research of affective polarization, and potential practical implications for attempts to reduce cross-party violence.

Empathy deficit in male patients with schizophrenia and its relationships with impulsivity and premeditated violence.

To explore the pattern of empathy characteristics in male patients with schizophrenia (SCH) and to examine whether empathy deficit is associated with impulsivity and premeditated violence. One hundred and fourteen male SCH patients were enrolled in this study. The demographic data of all patients were collected and the subjects were divided into two groups, namely, the violent group, including 60 cases, and the non-violent group, comprising 54 cases, according to the Modified Overt Aggression Scale (MOAS). The Chinese version of the Interpersonal Reactivity Index-C (IRI-C) was used to evaluate empathy and the Impulsive/Predicted Aggression Scales (IPAS) was employed to assess the characteristics of aggression. Among the 60 patients in the violent group, 44 patients had impulsive aggression (IA) and 16 patients had premeditated aggression (PM) according to the IPAS scale. In the violent group, the scores of the four subfactors of the IRI-C, i.e., perspective taking (PT), fantasy (FS), personal distress (PD), and empathy concern (EC), were significantly lower than in the non-violent group. Stepwise logistic regression showed that PM was independent influencing factor for violent behaviors in SCH patients. Correlation analysis revealed that EC of affective empathy was positively correlated with PM but not with IA. SCH patients with violent behavior had more extensive empathy deficits compared with non-violent SCH patients. EC, IA and PM are independent risk factors of violence in SCH patients. Empathy concern is an important index to predict PM in male patients with SCH.

Characteristics and associated factors of violence in male patients with schizophrenia in China.

To investigate the characteristics and associated factors of violence in male patients with schizophrenia in China. A total of 507 male patients with schizophrenia were recruited, including 386 non-violent and 121 violent patients. The socio-demographic information and medical history of the patients were collected. Psychopathological characteristics, personality traits psychopathology, and factors related to risk management were assessed using the Brief Psychiatric Rating Scale (BPRS), the History of Violence, Clinical, Risk Assessment Scale (HCR-20), and the Psychopathy Checklist-Revised (PCL-R), as appropriate. Differences in these factors were compared between the violent and non-violent patients, and logistic regression analysis was performed to explore the risk factors for violence in male patients with schizophrenia. The results showed that the violent group had a lower level of education, longer duration of illness, as well as a higher rate of hospitalization, history of suicidal attempts, and history of alcohol compared with the non-violent group. The violent group scored higher in items of symptoms in BPRS, personality traits and psychopathy in PCL-R, and risk management in HCR-20. The regression analysis showed that previous suicidal behavior (OR = 2.07,95% CI [1.06-4.05], P = 0.033), antisocial tendency in PCL-R (OR = 1.21, 95% CI [1.01-1.45], P = 0.038), H2: young age at violent incident (OR = 6.39, 95% CI [4.16-9.84], P < 0.001), C4: impulsivity (OR = 1.76, 95% CI [1.20-2.59], P = 0.004), and H3: relationship instability (OR = 1.60, 95% CI [1.08-2.37], P = 0.019) in HCR-20 were risk factors of violence among male patients with schizophrenia. The present study found significant differences in socio-demographic information, history of treatment, and psychopathy characteristics between male patients with schizophrenia who had engaged in violent behaviors and their non-violent counterparts in China. Our findings suggested the necessity of individualized treatment for male patients with schizophrenia who had engaged in violent behaviors as well as the use of both HCR-20 and PCL-R for their assessment.

Risk assessment of agressive behavior in schizophrenia and schizoaffective disorder : a cross-sectional study

IntroductionPsychotic disorders have been consistently associated with aggressive behaviors. Psychiatrists are frequently asked to perform assessment regarding potentially aggressive patients. Thus, many psychometric instruments can be useful for identifying the risk of violence and thereby offering appropriate treatment for these individuals.ObjectivesThe aims of this study were to assess the risk of agressive behavior in inpatients with schizophrenia or schizoaffective disorder and to determine its correlates.MethodsUsing face-to-face interviews, inpatients diagnosed with schizophrenia or schizoaffective disorder, in psychiatric department of the University Hospital in Sfax (Tunisia) were included in this cross-sectional, descriptive and analytical study, carried out between novembre 2020 and octobre 2022.The modified overt aggression scale (MOAS) and historical clinical risk management-20 (HCR-20) questionnaire were used for data acquisition. The HCR-20 score of 20 was used as threshold to divide the sample to violent patients (scoring&gt;20) and non-violent patients (scoring ≤ 20).ResultsThe sample consisted of 60 male inpatients. The mean age was 38.23± 10.37 years.In our sample, 68.3% were single, 35% didn’t reach the secondary educational level, 16.7% used psychoactive substance(s), 35% had prior criminal record, 30% had a history of suicidal attempt and 81.7% had previous hospitalization.The mean score of MOAS was 13.08±8.19. The mean total HCR-20 score was 19.25±5.26. The Historical, Clinical and Risk Management subscales showed mean scores of 8.33±2.96, 5.62±1.89, and 5.28±2.42, respectively.The violent patients represented 45% of the sample.The mean scores of the items H3, H10, C1, C2, C4 and R5 of HCR-20 were respectively : 1.33±0.79, 1.20±0.77, 1.22±0.88, 0.38±0.71, 1.30±0.64 and 1.28±0.73.There was no statistical difference between the two groups in socio-demographic factors.A history of suicidal attempts was significantly more common in the group of violent patients (p=0.029).Regarding the HCR subscales, H3 score (relationship instability) and H10 score (Prior supervision failure) were significantly higher among violent patients (p=0.018 and 0.003 respectively). The C1 score (lack of insight), the C2 score (negative attitudes) and the C4 score (impulsivity) were also significantly higher among violent patients (p=0.016, 0.009 and 0.005 rescpectively).The item R5 (stress) of the risk management subscale was significantly higher in the group of violent patients (p=0.003).The total MOAS score detected severe agression in the nonviolent group (p=0.031).ConclusionsOur study suggests the efficacy of HCR-20 in identifying and distinguishing between violent and nonviolent patients with schizophrenia or schizoaffective disorder. The use of such reliable instrument in clinical psychiatric settings should be encouraged.Disclosure of InterestNone Declared

Evolution of impulsivity levels in relation to early cannabis use in violent patients in the early phase of psychosis.

Prevention of violent behaviors (VB) in the early phase of psychosis (EPP) is a real challenge. Impulsivity was shown to be strongly related to VB, and different evolutions of impulsivity were noticed along treatments. One possible variable involved in the relationship between VB and the evolution of impulsivity is cannabis use (CU). The high prevalence of CU in EPP and its relationship with VB led us to investigate: 1/the impact of CU and 2/the impact of early CU on the evolution of impulsivity levels during a 3-year program, in violent and non-violent EPP patients. 178 non-violent and 62 violent patients (VPs) were followed-up over a 3 year period. Age of onset of CU was assessed at program entry and impulsivity was assessed seven times during the program. The evolution of impulsivity level during the program, as a function of the violent and non-violent groups of patients and CU precocity were analyzed with linear mixed-effects models. Over the treatment period, impulsivity level did not evolve as a function of the interaction between group and CU (coef. = 0.02, p = 0.425). However, when including precocity of CU, impulsivity was shown to increase significantly only in VPs who start consuming before 15 years of age (coef. = 0.06, p = 0.008). The precocity of CU in VPs seems to be a key variable of the negative evolution of impulsivity during follow-up and should be closely monitored in EPP patients entering care since they have a higher risk of showing VB.

Winstanley's “Righteous Actors”: Performance, Affect, and Extraordinary Politics in the Seventeenth Century

On the first day of April 1649, on the predominantly rural manor of Walton, Surrey, the sight of people preparing land for the plow was unremarkable. To see men up at dawn, dressed for the field in broad-brimmed hats, homespun waistcoats, and short breeches, loosening or breaking up clods with their spades, stooping to toss aside root and rock, was typical. What did raise eyebrows, however, was the sight of such busyness on a Sunday, the Sabbath, and on no less remarkable ground than George Hill, with its “very barren,” sandy soil. When questioned, Gerrard Winstanley reframed this performative break with religious, social, and agricultural norms as he did in his soon to be published manifesto, The True Levellers’ Standard Advanced. To work this land was to “declare . . . by action,” as well as by word, that Winstanley, the self-described “prophet” William Everard, and a small number of others had been sent by the Creator to begin their mission of transforming “the Earth [into] a common Treasury for all, both Rich and Poor.” Rural, religious, and resource poor, the Digger collective has not received substantial attention from performance studies scholars. Even some historians of the seventeenth century have questioned the significance of this small, nonviolent agrarian group in the intensely “charged political atmosphere of the 1640s,” but as a collective whose theatrical social performances raised them from obscurity to national visibility, Diggers are in some ways the epitome of this era.

Violent Behavior Prior to Admission Is Not a Factor in Further Prolonged Length of Stay: A Retrospective Cohort Study in a Japanese Psychiatric Hospital.

Background: This study assessed the hypothesis that violent behavior prior to admission prolongs psychiatric hospitalization and evaluated the likelihood of hospital discharge to a community care setting based on demographic and clinical factors, with an emphasis on violent behavior.Methods: We retrospectively selected 362 patients who were involuntarily admitted to a psychiatric hospital in Japan from December 1, 2015 to November 30, 2017, stayed longer than planned, and underwent review by a multidisciplinary team. We assessed (a) education and marital status and history of substance abuse, (b) the presence/absence and type of violent behavior that led to hospital admission, and (c) the discharge criteria. We divided the subjects into groups according to whether they had demonstrated violent behavior prior to admission and compared demographic and clinical variables between the groups using bivariate analysis. We also analyzed data using the Cox proportional hazard model, defining discharge to the community as the outcome. Age, sex, and variables that were significant at a level of P < 0.05 based on Cox univariate analysis were included in the multivariate models using the forced entry method.Results: The Violent group included 94 patients (26%). There were no significant between-group differences in age, sex, educational background, marital history, career history, or the history of substance abuse. However, hospitalization was significantly longer in the Non-violent group. The Cox proportional multivariate hazard ratios revealed that violent behavior prior to admission resulted in a higher probability of hospital discharge.Conclusion: Violent behavior prior to admission did not significantly contribute to prolonged hospitalization in patients who deviated from the treatment plan and had exceeded the planned hospitalization duration. Our findings recommend caution when using violence and impulsiveness observed during the acute stage to predict the difficulty of long-term treatment.

Candidate symptomatic markers for predicting violence in schizophrenia: A cross-sectional study of 7711 patients in a Chinese population.

Violent behaviour is an alarming problem among schizophrenia patients. The effects of historical, clinical, and pathological risk factors for violence have been investigated by multiple studies, but consensus has not been achieved. As psychotic symptoms are more direct and intuitive indicators for violence, identifying robustly associated symptoms is a crucial part of the future prediction and precise management of violent patients in clinics. This study aims to identify the psychotic symptoms correlated with violence among schizophrenia patients in a Chinese population. In this cross-sectional study, the medical records of 7711 schizophrenia patients (4711 in the discovery set and 3000 in the validation set) were collected from 1998 to 2010. Their psychotic symptoms were extracted, and the patients were divided into violent and non-violent groups. Multivariate logistic analysis was applied to identify symptoms associated with violence in the discovery set. Eight psychotic symptoms were found to be significantly correlated with violence in schizophrenia. "Destruction of property", "verbal aggression" and "insomnia" increased the risk of violence, while "flat affect", "delusion of persecution", "auditory hallucination", "vagueness of thought" and "poverty of thought" decreased the risk of violence. The regression model was evaluated by receiver operating characteristic (ROC) analysis for its discriminatory performance, achieving area under curve (AUC) values of 0.887 in the discovery sample set and 0.824 in the validation sample set. The correlated symptoms identified by this study can serve as future candidate predictors for violence in schizophrenia, paving the way for precise management of schizophrenia patients in clinics.

The Tactical Use of Civil Resistance by Rebel Groups: Evidence from India’s Maoist Insurgency

Research on rebel behavior during conflicts has traditionally focused on the use of violent tactics. However, evidence from several intrastate wars suggests that armed groups also occasionally employ general strikes—a method of civil resistance that has typically been associated with nonviolent groups. But when do rebels resort to general strikes? I argue that these tactics have a particular function which can offset potential risks for rebels after they have suffered losses in previous battles: Through general strikes, rebels signal sustained authority to the local population. The argument is tested for districts in Eastern India using newly compiled, disaggregated data on contentious action during the Maoist conflict. The paper contributes to a burgeoning literature on wartime civilian activism in two ways: First, it shows that armed groups themselves rely situationally on civilian mobilization. Second, it investigates the effect of conditions endogenous to the conflict on these tactical choices.

Neuropsychological features in patients with severe mental disorders and risk of violence: A prospective multicenter study in Italy

In Severe Mental Disorders (SMDs) the most important cognitive deficits involve the Executive Functions (EFs). In this study we examined the association between EFs and aggressive behaviour in outpatients with SMDs. We included a total of 247 outpatients divided into two groups: ‘cases’, patients with a history of violence (N=126) and ‘non-violent’ (N=121). We compared their EFs score and then categorized the participants into four groups (Pathological Non-Violent comparison group; Non-Pathological Non-Violent comparison group; Pathological Violent cases and Non-Pathological Violent cases), based on the scores of a subtest assessing processing speed (i.e., Symbol-coding task) of the Brief Assessment of Cognition in Schizophrenia (BACS). We followed the 4 groups during a 1-year follow-up (FU) monitoring violent behaviour with the Modified Overt Aggression Scale (MOAS). According to the classification based on the BACS-Symbol Coding Task we found no statistically significant differences between subgroups in MOAS scores. We only found that the trend curve for PV was almost consistently over the other group curves in the MOAS ‘aggression against people’. Our results suggested a worse performance in the violent compared to non-violent group in EFs. Despite this evidence, the score on the processing speed task was not associated with aggressive behaviour during FU.

A brief review of the relationship of executive function assessment and violence

This review analyzes nine studies comparing violent or aggressive groups to nonviolent groups on tests of executive function (EF). The purpose is to determine if those committing violence, or scoring highly on assessments of impulsive aggression, demonstrate significant impairment in EF while controlling for variables such as age, education, head trauma, substance use, and intelligence. The reviewed studies tested a diverse selection of offenders, including murderers, domestic offenders, sexual offenders, perpetrators of assault, and batterers. The characteristic finding from the examined studies was that errors on Trail Making Test- Part B and various scores from the Wisconsin Card Sorting Test differentiated violent and nonviolent persons more consistently than other EF tests used. Violent offenders also performed significantly worse on tests of verbal fluency and general verbal ability compared to nonviolent individuals. Additionally, the Wisconsin Card Sorting Test was able to differentiate between different types of violent offenders. These results held across the type of crime committed, as well as incarcerated individuals, and individuals who self-reported as being physically aggressive. • Purpose was to determine if those committing violence show impairment in executive function while controlling for variables • Participants in studies included murderers, domestic offenders, sexual offenders, perpetuators of assault, and batterers • Errors on Trails Making Test- Part B and various scores from Wisconsin Card Sorting Test differentiated violent from non-violent offenders • Violent offenders performed worse on verbal fluency and general verbal ability than non-violent offenders • Wisconsin Card Sorting Test differentiated between different types of violent offenders

Comparing the Different Behavioral Outcomes of Extremism: A Comparison of Violent and Non-Violent Extremists, Acting Alone or as Part of a Group

Presented here is an exploratory study that compared four kinds of extremists (violent lone, nonviolent lone, violent group member, and nonviolent group member). Thematic analysis of 40 case studies identified five key themes and a number of subthemes that comprised a range of underlying variables. Comparisons of the four groups showed that in many ways violent and nonviolent extremists acting alone or as part of a group do not differ. However there were some variables that distinguished between groups. Findings are discussed in terms of implications for countering and preventing violent extremism.

Association of Corticotropin-Releasing Hormone Receptor-1 Gene Polymorphisms and Personality Traits with Violent Aggression in Male Adolescents.

There is evidence that corticotropin-releasing hormone receptor 1 (CRHR1) gene polymorphisms and indifferent impulsive personality traits play an important role in violent aggression in male adolescents. Genotyping for two tag single-nucleotide polymorphisms (SNP) (rs242924, rs17689966) was conducted using TaqMan SNP for 138 violent young male criminals, 98 nonviolent young male criminals, and 153 noncriminal adults. The general situation and personality traits (SSP) questionnaire was given to the young violent and nonviolent male criminal groups. The results showed that the frequency of the G allele in rs242924 of the CRHR1 gene in the violent aggression group was higher than that in the normal adult controls (P < 0.025, OR = 2.29, 95% CI = 1.13-4.62). The difference in genotype distribution was significant among the three groups (P < 0.05), and when the violent group was compared with the two control groups, no significant difference was found (P > 0.025). The impulsiveness, trait irritability, verbal trait aggression, and physical trait aggression scores in the violent group were significantly higher than those in the nonviolent group of adolescents. These findings suggest that the variance in CRHR1 gene polymorphisms and personality traits may play a role in violent aggression in male adolescents, and that the interaction of the CRHR1 gene and the impulsive personality trait may cause an increased susceptibility to violence towards others.

Criminalizing peace: anti-terrorism law and its impact on peacemaking in the Basque Country and Northern Ireland

ABSTRACT This paper investigates anti-terrorism law’s impact on peace-making efforts of the nonviolent allies of Basque Homeland and Freedom (ETA) and the Provisional Irish Republican Army (IRA). Drawing on debates concerning ‘enemy criminal law’, I argue that anti-terrorism law is actor-focused and thus directed at juridically labelled ‘terrorist organisations’. Variation in the juridical construction of terrorist organisations is critical to understanding the divergence in the political capacities of non-violent Basque separatists and Irish republicans as peace-makers. In Spain, the judiciary developed a broad definition of the ‘terrorist organisation ETA’, resulting in the identification of non-violent Basque separatist groups as ‘integral components’ of ETA and hindering their capacity to engage in peace-making. In contrast, British anti-terrorism law was grounded in a narrow definition of ‘proscribed organisations’ focused on the IRA’s rank-and-file, which facilitated the involvement of the broader republican movement in the successful peace process of the nineties.

Identifying Violent Behavior Using the Oxford Mental Illness and Violence Tool in a Psychiatric Ward of a German Prison Hospital.

Background: Although there is evidence that individuals who suffer from severe mental disorders are at higher risk for aggressive behavior, only a minority eventually become violent. In 2017, Fazel et al. developed a risk calculator (Oxford Mental Illness and Violence tool, OxMIV) to identify the risk of violent crime in patients with mental disorders. For the first time, we tested the predictive validity of the OxMIV in the department of psychiatry at the prison hospital in Berlin, Germany, and presented findings from our internal validation. Materials and Methods: We designed a cohort study with 474 patients aged 16–65 years old who met the inclusion criteria of schizophrenia-spectrum or bipolar disorder and classified the patients into two groups: a violent group with 191 patients and a nonviolent group with 283 patients. Violence was defined as the aggressive behavior of a patient with the necessity of special observation. We obtained all the required information retrospectively through patient files, applied the OxMIV tool on each subject, and compared the results of both groups. Sensitivity, specificity, and positive/negative predictive values were determined. We used logistic regression including variable selection and internal validation to identify relevant predictors of aggressive behavior in our cohort. Results: The OxMIV score was significantly higher in the violent group [median 4.21%; Interquartile range (IQR) 8.51%] compared to the nonviolent group (median 1.77%; IQR 2.01%; p < 0.0001). For the risk of violent behavior, using the 5% cutoff for “increased risk,” the sensitivity was 44%, and the specificity was 89%, with a positive predictive value of 72% and a negative predictive value of 70%. Applying logistic regression, four items were statistically significant in predicting violent behavior: previous violent crime (adjusted odds ratio 5.29 [95% CI 3.10–9.05], p < 0.0001), previous drug abuse (1.80 [1.08–3.02], p = 0.025), and previous alcohol abuse (1.89 [1.21–2.95], p = 0.005). The item recent antidepressant treatment (0.28 [0.17–0.47]. p < 0.0001) had a statistically significant risk reduction effect. Conclusions: In our opinion, the risk assessment tool OxMIV succeeded in predicting violent behavior in imprisoned psychiatric patients. As a result, it may be applicable for identification of patients with special needs in a prison environment and, thus, improving prison safety.

Cyber-aggression in adolescence and internet parenting styles: A study with victims, perpetrators and victim-perpetrators

Cyber-aggression is the new form of interpersonal violence among adolescents. This study examines the prevalence of cyber-aggression and its differentiation in terms of adolescents' sociodemographic characteristics and digital practices, as well as parenting styles experienced by four groups: non-violent, victim, perpetrator and victim-perpetrator Finally, we add an in-depth view of the predictors of becoming double involved. A sample of 627 adolescents (12- to 16-years-old) from schools in northern Portugal and the Azores answered two questionnaires. The results show that 63.1% reported being involved in cyber-aggression, with 31.1% admitting to being victim-perpetrators. Adolescent girls and younger adolescents, both girls and boys, characterized the non-violent and victims' groups, whereas the perpetrators and victim-perpetrators groups were characterized by adolescent boys and older adolescents, both boys and girls. A higher frequency of information and communication technology use and cyber-practices/risks were associated with victim-perpetrators. Further, individuals in the non-violent group were more likely to perceive their parents' parenting styles as authoritative and authoritarian and victim-perpetrators as permissive and laissez-faire. Additionally, laissez-faire parenting affects adolescents' cyber-involvement. This relationship is, however, mediated by the frequency of adolescents' cyber-practices/risks. Calling without justification, sending exaggerated messages of affection, sending insulting messages and sending pornographic images or messages were the most prevalent behaviours among the victim-perpetrators. Victimization-perpetration increased when adolescents published personal information, consulted erotic websites or arranged offline meetings with someone whom they had met online only. Theoretical and practical implications are discussed.

Psychosocial and Health Outcomes of Adults With Violently Acquired Pediatric Spinal Cord Injury.

Objective: To describe the psychosocial and medical outcomes of individuals with pediatric-onset spinal cord injury (SCI) as a result of violent injuries. Methods: This was a cross-sectional study assessing adult outcomes associated with pediatric-onset SCI. Participants completed measures assessing demographics, injury characteristics, secondary conditions, and psychosocial functioning. Results: Participants included 483 adults (ages 19-51 years; M = 32.89, SD = 6.81) who sustained an SCI prior to age 19 (0-18 years; M = 14.25, SD = 4.40). Participants tended to have complete injuries (68%) and tetraplegia (53%) and were predominantly male (63%) and Caucasian (85%). The violent (n = 42) and nonviolent (n = 441) etiology groups tended to be similar in terms of gender. The violent etiology (VE) group, however, was significantly more likely to have paraplegia (χ2 = 7.45, p = .01), identify as an ethnic minority (χ2 = 5.40, p = .02), and have decreased odds of completing a college degree (odds ratio [OR], 0.40; 95% CI, 0.19-0.83). After controlling for significant covariates, individuals in the VE group were more likely to have moderate depression symptoms (OR, 3.73; 95% CI, 1.35-10.30) and significantly lower odds of economic independence (OR, 0.39; 95% CI, 0.19-0.84). The VE group was also 2 times as likely as the nonviolent group to report a pressure injury (OR, 2.04; 95% CI, 1.05-3.94) or activity interfering pain (OR, 2.34; 95% CI, 1.15-4.74). Conclusion: The results of this study reveal significantly greater psychosocial health concerns and more medical complications for individuals with violent SCI than those with nonviolent SCI. Children with an SCI from a violent etiology may warrant additional attention and services aimed at promoting stability and long-term resilience.
