Traumatic brain injury,temperament, and violence in incarcerated youth: a mediation analysis based on Delisi and Vaughn’s theory of temperament and antisocial behavior

Traumatic brain injury (TBI) is associated with violent behavior. A possible key mechanism to explain the relationship between TBI and violence is DeLisi and Vaughn’s temperament-based theory of antisocial behavior. Accordingly, the current study investigates whether temperament – the combination of effortful control and negative emotionality – mediates the relationship between TBI and violent behavior within incarcerated youth. A non-probability sample of youth (N?=?227) incarcerated in two long-term residential facilities completed a comprehensive assessment tool that collected data on TBI, temperament, childhood trauma, substance use, mental illness, and a variety of demographic characteristics. Preliminary results showed TBI significantly increased violent behavior, adjusting for confounds. Then, mediation analysis found that temperament accounted for 54% of the total effect between TBI and violence. The study findings show the potency of DeLisi and Vaughn’s temperamental construct in explaining the relationship between TBI and violent behavior within a sample of incarcerated youth. The dynamic interplay between effortful control and negative emotionality appears to be an important mechanism related to violent behavior. Both temperament constructs should be the focus of future assessment and intervention among incarcerated youth with TBI.     

Why are some ethnic groups more violent than others? The role of friendship network's ethnic composition

Ethnic differences in violent behavior can be found in official crime statistics, as well as in surveys on juvenile delinquency. To explain these differences, research mainly focuses on factors like parental violence, violence legitimizing norms of masculinity, or socio-economic status. Little research has examined the role of friendship network's ethnic composition on ethnic differences in violent behavior, although different sociological and criminological theories suggest that the composition of friendship networks can play an important role for attitudes and behavior of its members. Using data of a survey conducted in 2006 among all ninth-grade pupils in Hanover (Germany), we investigated the influence of friendship network's ethnic composition on violent behavior in general, and on ethnic differences in violent behavior in particular. Due to the specific sampling procedure, it was also possible to look for neighborhood effects both on (ethnic differences in) juvenile delinquency and friendship network composition. Findings indicate that there are significant differences in the network composition across the ethnic groups. After controlling for these network characteristics, ethnic differences in violent behavior disappeared. Furthermore, the results show that the friendship network's ethnic composition also depends on community characteristics.     

Development of the Observation Scale for Aggressive Behavior (OSAB) for Dutch forensic psychiatric inpatients with an antisocial personality disorder

The Observation Scale for Aggressive Behavior (OSAB) has been developed to evaluate inpatient treatment programs designed to reduce aggressive behavior in Dutch forensic psychiatric patients with an antisocial personality disorder, who are "placed at the disposal of the government". The scale should have the sensitivity to measure changes in the possible determinants of aggressive behavior, such as limited control of displayed negative emotions (irritation, anger or rage) and a general deficiency of social skills. In developing the OSAB 40 items were selected from a pool of 82 and distributed among the following a priori scales: Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent (to aggressive behavior), Sanction (for aggressive behavior) and Social behavior. The internal consistency of these subscales was good, the inter-rater reliability was moderate to good, and the test-retest reliability over a two to three week period was moderate to good. The correlation between the subscales Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent, Sanction was substantial and significant, but the anticipated negative correlation between these subscales and the Social behavior subscale could not be shown. Relationships between the corresponding subscales of the OSAB and the FIOS, used to calculate concurrent validity, yielded relatively high correlations. The validity of the various OSAB subscales could be further supported by significant correlations with the PCL-R and by significant but weak correlations with corresponding subscales of the self-report questionnaires. The Observation Scale for Aggressive Behavior (OSAB) seems to measure aggressive behavior in Dutch forensic psychiatric inpatients with an antisocial personality disorder reliably and validly. Contrary to expectations, a negative relationship was not found between aggressive and social behavior in either the OSAB or FIOS, which were used for calculating concurrent validity.     

Attributions of Negative Partner Behavior by Men Who Physically Abuse Their Partners

This study investigated the association between family violence and the attributions made for negative partner behaviors in an Australian context. Three groups of men were classified as physically violent (in counseling), non-physically violent (in counseling), and non-physically violent (in the community). The Relationship Attribution Measure was used to assess the attributional dependent variables of locus, stability, globality, intent, motivation, and blame. Significant differences between violent and nonviolent men on each of the attributional dimensions were found. Physically violent men were more likely than non-physically violent men (counseling) to attribute the negative behavior of their partners to unchangeable, intentional rather than unintentional, selfishly motivated, and blameworthy causes. However, these differences disappeared when marital satisfaction was controlled. The implications of this work for domestic violence intervention programs are discussed, along with a number of methodological issues and directions for future research.     

On intelligence and crime: a comparison of incarcerated sex offenders and serious non-sexual violent criminals

The impact of low IQ on crime has been a focus of debate for several decades now. Although sociologists have virtually removed it from the list of possible factors influencing crime, the impact of IQ on crime continues to generate a significant amount of scientific research and a substantial number of publications. The purpose of this study is to assess intellectual levels and to compare two groups of incarcerated criminals. Using MANCOVA and ANCOVA procedures, 261 sex offenders and 150 non-sexual violent criminals were compared on IQ subscales. The results show significant differences on vocabulary, comprehension, arithmetic, mental math computations, object assembly, letter-number sequencing, and perception subscales, as well as on performance IQ and total IQ. The impacts of penal filtering and sample composition are hypothesized to explain differences between the two subgroups. Theoretical and practical implications are discussed.     

FAMILY ORIGINS OF VIOLENT DELINQUENTS*

Family is central to contemporary theories of delinquent and violent behavior. Yet, the processes by which families shape violent behavior in their children are not well understood. In the past, structural views posited that a weak family exposed a child to the evils of the street. More recently, functionalists have suggested that the family plays an active role in socializing youths to violent behaviors through supervision and discipline practices and modeling and reinforcement of antisocial behaviors. Integrated theories presume that socially disorganized families weaken children's conventional bonds and attachments, leading to associations with delinquent peers and in turn antisocial behavior. However, the influence of the family as a socializing environment may shift over time, and some suggest that its influence is overshadowed during adolescence by that of other social domains—schools, neighborhoods, peers, and work. This study describes the family processes and environments of (n = 98) chronically violent delinquents. Interviews with youths and their mothers assessed family social process and environments and the social domains and institutions with which they interact. Analyses of youth reports of family environments and processes yield three family types: “interactionist” families exhibiting a high degree of internal interaction and bonding; “hierarchical” families characterized by parental dominance and the presence of family bond and interaction patterns; and “antisocial” families marked by criminality and family violence. Family variables have weaker explanatory power than do other social influences on violent delinquency. The relative contributions of family supervision practices and school environment varied by crime type. Social influences outside the family appear as stronger contributors to delinquency and violence during adolescence, regardless of early childhood experiences. The results underscore the importance of integrating social policies regarding family, crime, and neighborhood.     

FAMILY VIOLENCE,TELEVISION VIEWING HABITS,AND OTHER ADOLESCENT EXPERIENCES RELATED TO VIOLENT CRIMINAL BEHAVIOR*

This study employs multivariate analyses with retrospective self-report data to assess the relative importance of certain childhood and adolescent experiences to the commission of violent crimes as an adult. Specifically, the relationship is examined between violent criminal behavior and exposure to family violence, exposure to television violence, school performance, other adolescent activities, and differential reinforcement for previous illegal acts. The exploratory model is based on data collected on 100 male inmates incarcerated for violent crimes and 65 nonincarcerated, nonviolent males matched in terms of age, race, and neighborhood. Findings, from analyses which estimate both additive and interactive effects, indicate that the background experiences associated with violent crime vary depending upon an individual's race. The discussion focuses on the implications of these findings for further research on the causes of violent criminal behavior.     

Empathy as a predictor of recidivism among young adult offenders

This longitudinal study examined the role of empathy in predicting recidivism among young adult offenders. During their prison terms, 748 male offenders between the ages of 15 and 28 were administered the interpersonal reactivity index (IRI; Davis, 1980). Official criminal records were used to determine general as well as violent recidivism during the (on average) five years following release from prison. Cox regression models of reoffense rates were calculated using IRI scales as explanatory variables while controlling for age, socioeconomic status, duration of imprisonment, and intelligence. The global empathy score and the subscales of perspective taking and empathic fantasy, but neither empathic concern nor personal distress, contributed to the prediction of recidivism. Furthermore, empathy did not contribute significantly to the prediction of violent reoffending. However, comparing offenders whose index crimes were violent versus nonviolent, violent offenders scored lower on the IRI and recidivated more often with a violent offence than did nonviolent offenders.     

Methamphetamine use, self-reported violent crime, and recidivism among offenders in California who abuse substances

This study uses data from 641 state prison parolees in California to examine the associations between methamphetamine use and three measures of criminal behavior: (a) self-reported violent criminal behavior, (b) return to prison for a violent offense, and (c) return to prison for any reason during the first 12 months of parole. Methamphetamine use was significantly predictive of self-reported violent criminal behavior and general recidivism (i.e., a return to custody for any reason). However, methamphetamine use was not significantly predictive of being returned to custody for a violent offense. These trends remained even after controlling for involvement in the drug trade (i.e., sales, distribution, or manufacturing).     

Exploring the forensic use of the emotional recognition test (ERT)

General "hypo-emotionality" has now become a broadly accepted concept as one of the conspicuous psychological characteristics of repetitive, violent offenders. Numerous psychophysiological studies have verified this premise. The current study sought to examine the applicability of the Emotional Recognition Test (ERT) in a sample of 85 Korean inmates in a maximum-security prison. Two additional criterion groups were included for comparison: normal controls and schizophrenic inpatients. Because the ERT consists of problem-solving items, it is relatively free from response biases and is more efficient than measuring physiological responses. Results indicated that all criterion groups scored significantly differently on the ERT total and subscale scores. Additionally, similar to the physiological emotion-specific findings, emotion-specific subscales of the ERT indicated that offenders had significantly more difficulty in recognizing negative emotional stimuli, particularly sadness.     

Loneliness and associated violent antisocial behavior: analysis of the case reports of Jeffrey Dahmer and Dennis Nilsen

It can be theorized that loneliness plays a significant role in the development and continuation of violent, antisocial attitudes and behavior. Analysis of case reports of two serial killers, Dennis Nilsen and Jeffrey Dahmer, indicate that there is evidence for such a link. In this article, a list of significant correlates of loneliness and antisocial behavior is presented. This may be useful for the assessment of possible dangerousness and in the development of prevention and intervention programs. Suggestions are made for the adequate treatment of loneliness and correlated violent, antisocial behavior. A need is recognized for more research into the psychosocial, emotional, neurobiological, cultural, and ethnic determinants of loneliness and their correlation to specific antisocial and/or criminal behavior.     

A comparison of rapists and sexual murderers on demographic and selected psychometric measures

This study compared 58 sexual murderers and 112 rapists who were about to undergo treatment in prison for their sexual offending behavior. The two groups were compared on background, personality, offense, and victim characteristics. The sexual murderer group were less likely to have been involved in a relationship at the time of their index offense, generally attacked older victims, and had higher self-esteem. The rapist sample were found to have more violent previous convictions and scored higher on measures of historical deviance (nonsexual), paranoid suspicion, and resentment. No differences were found on the personality or clinical syndrome scales of the Millon Clinical Multiaxial Inventory-III. However, the rapist sample had significantly higher mean scores on the Paranoid Suspicion, Resentment, and Self-Esteem subscales of the Antisocial Personality Questionnaire. Future research should compare the two groups on dynamic or changeable factors to determine differential treatment needs.     

On the predictability of violent behavior: considerations and guidelines

Following a semantic discussion of dangerousness, and having established its dynamic concept, the authors define the prediction of dangerous behavior as the anticipation of an antisocial act towards others. The present-day dilemma of predicting dangerous behavior is discussed. An extensive review of sociological and psychiatric studies is presented. Further, the authors stress the vital importance of predicting violent behavior in view of statistical data concerning rampant violent crime in the United States. They encourage more cooperation between psychiatric experts and the judicial system in view of the common social problem all are faced with. Better diagnostic procedures and more logically deductive factual expert reports are hoped for. The authors postulate that prediction is strictly connected with the possible prevention of dangerous behavior and the continuation of a civilized, secure society.

Aggression and rule-breaking: Heritability and stability of antisocial behavior problems in childhood and adolescence

Purpose

This twin study examined the structure of genetic and environmental influences on aggression and rule-breaking in order to examine change and stability across the span of childhood to mid-adolescence.

Methods

Behavioral assessments were conducted at two time points: age 9–10 years and 14–15 years. Using behavioral genetics biometric modeling, the longitudinal structure of influences was investigated.

Results

Aggression and rule-breaking were found to be influenced by a latent common factor of antisocial behavior (ASB) within each wave of data collection. The variance in the childhood-age common factor of ASB was influenced by 41% genetics, 40% shared environment and 19% nonshared environment. In adolescence, 41% of variance in the common factor were novel and entirely genetic, while the remainder of variance was stable across time. Additionally, both aggression and rule-breaking within each wave were found to have unique influences not common across subscales or across waves, highlighting specificity of genetic and environmental effects on different problem behaviors at both ages.

Conclusions

This research sheds light on the commonality of influences on different forms of antisocial behavior. Future research into interventions for antisocial behavior problems in youth could focus on adolescence-specific environmental influences.     

THE IMPACT OF ORDER‐MAINTENANCE POLICING ON NEW YORK CITY HOMICIDE AND ROBBERY RATES: 1988‐2001*

Local officials and national observers have attributed the New York City drop in violent crime during the 1990s to the aggressive enforcement of public order, but relevant research is limited and yields contrasting conclusions regarding the effects of order‐maintenance policing (OMP) on violent crime trends in New York City. The current study investigates the effects of order‐maintenance arrests on precinct‐level robbery and homicide trends in New York City with more reliable crime and arrest data, longer time series, and more extensive controls for other influences than used in prior research. We find statistically significant but small crime‐reduction effects of OMP and conclude that the impact of aggressive order enforcement on the reduction in homicide and robbery rates in New York City during the 1990s was modest at best.     

A nine-year follow-up study on the predictive validity of the Self-Appraisal Questionnaire for predicting violent and nonviolent recidivism

The effectiveness of the Self-Appraisal Questionnaire (SAQ) in providing estimates for predicting violent and nonviolent recidivism over a 9-year period is examined. The SAQ is a quantitative risk/need instrument consisting of 72 items that compose eight subscales. There were 657 federally sentenced Canadian male offenders who completed the SAQ prior to their release and were followed up for 9 years (108 months) at 4-month intervals. Consistent with previous predictive studies, the results presented here demonstrate that the SAQ has adequate predictive validity.     

Intimidation and Street Gangs: Understanding the Response of Victims and Bystanders to Perceived Gang Violence

While research routinely examines the influence of gang membership on the quantity of violent crime involvement, less is known about the influence of gang violence on the situational characteristics of violent victimization. Felson’s discussion of street gangs highlights the possible functional role gang membership plays in the commission of violent crime; what he terms “the street gang strategy.” This study examines the functionality of gang membership during violent crimes by investigating the influence of perceived gang membership on the likelihood of victim resistance, bystander intervention, and police reporting using data from the National Crime Victimization Survey. Findings offer little support for the idea that gang members intimidate victims and bystanders to the extent that their behavior during and after violence differs systematically from responses resulting from non‐gang violence. Results are discussed in terms of their policy relevance and implications for future research.     

A classification of psychological factors leading to violent behavior in posttraumatic stress disorder

Posttraumatic stress disorder has long been linked to violent behavior. However, the exact nature of that association remains poorly characterized due to the limitations of knowledge in the area of phenomenology, contextual factors, the biology, and the nature of the aggression involved in the disorder. A clear understanding of the genesis of violence in posttraumatic stress disorder can be helpful to those involved in assessing psychiatric-legal issues relevant to the disorder and in its therapeutic management. In this article, we review the potential psychological links between posttraumatic stress disorder secondary to combat exposure and violent behavior and suggest a tentative classification of the main psychological causes of violence in that syndrome.     

Violence in geriatric patients with dementia

Although the elderly have been studied as victims of violent behavior, there has been little investigation of this population as perpetrators of violence. Using the method of retrospective chart review, this study examines the issue of violence by geriatric patients with dementia who need acute psychiatric hospitalization. Of 52 patients, 44 percent engaged in physical attacks and/or fear-inducing behavior during the two weeks prior to admission, and 29 percent engaged in similar behavior within the first 72 hours of hospitalization. Married patients and those who lived with family were overrepresented in the group of violent patients. The authors discuss possible explanations and implications of these findings.
