Capgras symptom associated parricides. 2 case reports

Capgras symptom is characterized by the delusional belief that a person significant to the patient has been replaced by a 'double' or 'impostor'. Capgras symptom was discussed to be associated with violent behavior. We report here the cases of two male patients with schizophrenia paranoid type, where parricide was connected to Capgras delusion. It is important to emphasize that in our observed cases, non-adherence played an essential role in the development of violent behavior, parricide. Orv Hetil. 2019; 160(42): 1673-1676.

PTSD as a Risk Factor for the Development of Violence Among Juvenile Offenders: A Group-Based Trajectory Modeling Approach.

Violent offending is a public health problem disproportionately perpetrated by adolescents. Posttraumatic stress disorder (PTSD) has been identified as a risk factor that increases an individual's odds of engaging in violent behavior. Juvenile offenders are a population indicated to be at high risk of the development and perpetuation of violent behavior across the life course. Despite the fact that PTSD also has a high prevalence among juvenile offenders, there has yet to be any research examining PTSD as a risk factor for violent offending among juvenile offenders. Furthermore, very little research has examined the development specifically of violent offending across adolescence among juvenile offenders. Using group-based trajectory modeling (GBTM), this research found four distinct violence trajectories that juvenile offenders followed through adolescence (Abstaining, Moderate Stable, Desisting, High Chronic). Using multinomial logistic regression, PTSD was found to more than double the risk of assignment to all three trajectory groups that demonstrated violent behavior at some point in adolescence relative to the Abstaining reference group. This research adds to the limited research conducted on the development of violent behavior through adolescence among juvenile offenders using the GBTM method. Furthermore, results indicate that PTSD is a risk factor for the perpetration of violent behavior. These results suggest that juvenile offenders may desist from violence even after high rates of violence have already been achieved and that screening of trauma victims may be important for providing juvenile offenders suffering from PTSD with proper treatment to mitigate risk of violent behavior.

Bullying in children and adolescents: a healthcare perspective

Bullying is a well-known problem among children, adolescents and young adults in USA. It has been associated with subsequent development of violent behaviors. In this article we are reviewing the medical and clinical aspects of bullying in children and adolescents, as well as providing recommendations to minimize its impact.

2099 – Clinical risk factors for interpersonal violence in adulthood in suicide attempters

Introduction Early environmental risk factors have a role in the development of violent behaviour in adulthood. Aims The aim of the study was to assess the impact of childhood trauma, expressed violent behaviour as a child, co morbid personality disorder and substance abuse on self reported interpersonal violence as an adult in suicide attempters. Methods A total of 161 suicide attempters were diagnosed with SCID I and II and assessed with the Karolinska Interpersonal Violence Scale (KIVS) measuring exposure to violence and expressed violent behaviour in childhood (between 6-14 years of age) and during adult life (15 years or older). A standard linear regression analyses was conducted with the two predictive KIVS subscales exposure to violence as a child and expressed violent behaviour as a child, Axis 1 mood and anxiety disorder diagnosis, co morbid substance abuse diagnosis, co morbid personality disorder diagnosis, age and gender as predictors of expressed interpersonal violence as an adult. Results The regression model was significant with adjusted R square 0.22, F ratio 7.2, DF=7, p Conclusions It is important to take into account expressed violent behaviour in childhood in violence risk assessments.

Violent crime runs in families: a total population study of 12.5 million individuals

Etiological theory and prior research with small or selected samples suggest that interpersonal violence clusters in families. However, the strength and pattern of this aggregation remains mostly unknown. We investigated all convictions for violent crime in Sweden 1973-2004 among more than 12.5 million individuals in the nationwide Multi-Generation Register, and compared rates of violent convictions among relatives of violent individuals with relatives of matched, non-violent controls, using a nested case-control design. We found strong familial aggregation of interpersonal violence among first-degree relatives [e.g. odds ratio (OR)sibling 4.3, 95% confidence interval (CI) 4.2-4.3], lower for more distant relatives (e.g. OR cousin 1.9, 95% CI 1.9-1.9). Risk patterns across biological and adoptive relations provided evidence for both genetic and environmental influences on the development of violent behavior. Familial risks were stronger among women, in higher socio-economic strata, and for early onset interpersonal violence. There were crime-specific effects (e.g. OR sibling for arson 22.4, 95% CI 12.2-41.2), suggesting both general and subtype-specific familial risk factors for violent behavior. The observed familiality should be accounted for in criminological research, applied violence risk assessment, and prevention efforts.

Domain specificity in relationship history, social-information processing, and violent behavior in early adulthood.

Using prospective longitudinal data, we tested 5 hypotheses: (a) that the relation between earlier developmental experiences (peer social rejection and victimization in a romantic relationship) and adult violent behavior toward peers and romantic partners is specific to relationship domain; (b) that the relation between social-information processing (SIP) biases and subsequent violence is also specific to relational domain (romantic partner vs. peer); (c) that the relation between developmental experiences and SIP biases is domain specific; (d) that domain-specific SIP mediates the impact of earlier developmental experiences on later violent behavior; and (e) that harsh parenting early in life is a domain-general predictor of SIP and later violent behavior. Harsh parenting was assessed through interviews with parents when their children were age 5 years. Classroom sociometric assessments indexing peer rejection were completed in elementary school, and self-report of victimization by romantic partners was provided at age 18 years. SIP was assessed via interview at age 22 years, and violent behavior was measured via self- and partner report at ages 23 years and 24 years. Structural equation analyses revealed specificity in the relation between developmental experiences and violence and in the prediction to and from SIP in the peer domain, but not in the romantic-relationship domain. The impact of early harsh treatment on violence toward peers was mediated by SIP biases in the peer domain. These findings provide support for domain specificity in the peer domain but for cross-domain generality in the romantic relationship domain in the development of violent behavior in early adulthood.

Familial risks, conduct disorder and violence

The aim was to investigate the impact of familial risk factors on the development of violent behaviour and conduct disorder (CD) by gender in a sample of adolescent psychiatric patients. The study sample consisted of 278 adolescents (age 12-17) consecutively admitted to psychiatric inpatient care between April 2001 and January 2004. DSMIV psychiatric diagnoses were obtained from the Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime (K-SADS-PL). Logistic regression analyses revealed that girls who had been physically abused at home had a 4.2-fold risk of having conduct disorder with violent behaviour (95% CI 1.4-12.2) compared to those not exposed to domestic violence. A broken primary family also increased the risk for having both violent CD (OR 7.8 95 % CI 1.7-36.4) and non-violent CD (OR 7.0 95% CI 1.5-33.5) among girls. Among boys, no statistically significant association was found between any familial risk factors and later CD. The results suggest that being physically abused by parents may influence the development of conduct disorder including violent behaviour among girls. This emphasizes the importance of early recognition of domestic violence. In girls, the absence of primary family seems to associate strongly with the development of CD, and should be taken into consideration by physicians and other professionals working with young people.

Risk Factors for Adolescent Violence

Violence as a function of vulnerability and delinquency was examined in a sample of 2066 ninth-graders. Vulnerability was examined by several proxy measures (being hit, attacked, or touched inappropriately at school; being exposed to weapons at school; the absence of the father from the home; and mother's educational attainment). Violence was a composite measure of the frequency of hitting a student, hitting or shoving a teacher, carrying a weapon at school, group fighting, and armed robbery. Vulnerability indicators explained 48% of the variance in violence in the first step of a hierarchical multiple regression analysis. Delinquency measures (crime involvement, punishment at school, and drug involvement) and attitudes toward school increased the explained variance to 74%. Vulnerability is posited as a potential central mechanism for the development of violent behavior. Prospective study of this mechanism is recommended.

Violence and youth.

Violence is looked at from ethological, biological and anthropological points of view. The family is examined to determine the roots of violence. Various prospective studies are reviewed to assess the role of temperament, social, familial and economic factors facilitating the development of antisocial and violent behaviour in the youth. There is also a look at the violence committed by groups, nations or governments in the name of God, flag or a just cause. The role that mental health professionals could play in preventing the development of violent behaviour is discussed.
