Reward dominance among children with disruptive behavior disorders

Investigated was a deficit in avoidance learning in situations of competing rewards and punishments in boys with behavior disorders. This learning style has been found to differentiate adults with psychopathy and controls and has been labeled reward dominance. The present study investigated the reward dominance paradigm in a group of 9- to 13-year-old boys with disruptive behavior disorders (N=21) and a normal control group (N=22). Subjects played four computer games programmed to provide the subject with a steadily decreasing ratio of rewards to punishments. Although the groups did not differ initially on the number of trials played, significant group differences emerged when measures of anxiety were included in the analysis. That is, boys with disruptive behavior disorders played more trials (reward dominance) only when the effect of anxiety was controlled. These findings are consistent with Gray's biobehavioral theory of personality and are also consistent with research indicating that anxiety is an important marker for a distinct subgroup of children with behavior problems.     

Direct and indirect bully‐victims: differential psychosocial risk factors associated with adolescents involved in bullying and victimization

The present study examined psychosocial risk factors that differentiated direct and indirect bully‐victims from bullies, victims and uninvolved adolescents. A total of 7,290 (3,756 girls) students (ages 13–18 yr) from a region of Southern Ontario, Canada, completed a number of self‐report measures to determine the relation between direct and indirect bullying and victimization and several psychosocial risk factors, including normative beliefs about antisocial acts, angry‐externalizing coping, social anxiety, depression, self‐esteem, temperament, attachment, parental monitoring and peer relational problems. ANCOVA and logistic regression analyses indicated that indirect bully‐victims and victims were similar in demonstrating greater internalizing problems and peer relational problems than indirect bullies and uninvolved participants. Furthermore, adolescents involved in indirect bullying (bullies, bully‐victims) reported a higher level of normative beliefs legitimizing antisocial behaviour and less parental monitoring (males only) than indirect victims and uninvolved participants. Only normative beliefs legitimizing antisocial behaviour distinguished direct bully‐victims and bullies from victims and uninvolved adolescents. Results illuminate the distinct characteristics of direct and indirect bully‐victims; theoretical and clinical implications are discussed. Aggr. Behav. 32:551–569. 2006. © 2006 Wiley‐Liss, Inc.     

Personality heterogeneity in adolescents with disruptive behavior disorders

We first confirmed adolescents diagnosed with disruptive behavior disorders (oppositional defiant, conduct disorder; n = 158) had lower constraint and higher negative emotionality, and greater psychiatric comorbidity and psychosocial dysfunction, relative to adolescents without (n = 755), in a population-based sample enriched for externalizing psychopathology (mean age = 17.90 years; 52% female). We then explored whether different personality types, defined by patterns of personality identified via latent profile analysis, were differently associated with clinical features in adolescents with a disruptive behavior disorder diagnosis. Four distinct personality types (“disinhibited,” “high distress,” “low distress,” “positive”) were meaningfully different from one another. Results highlight personality heterogeneity as a means of identifying individuals at greatest risk for the most deleterious forms of externalizing psychopathology.     

Cross-contextual stability of bullying victimization: a person-oriented analysis of cyber and traditional bullying experiences among adolescents

Using a person-oriented approach the study examined whether bullying victimization at school continued into cyberspace victimization in a large sample of high school students in Lithuania (N = 1667, 58% girls), age 15-19 (M = 17.29, SD = 0.95). Three forms of traditional bullying (verbal, physical and relational) and seven forms of cyberbullying victimization through cell phones and computers were included in the analysis. The findings revealed that 35% of traditional bullying victims were also bullied in cyberspace. In particular, adolescents who experienced predominantly verbal and relational bullying at school, showed a higher risk of victimization in cyberspace a year later, while this was not observed for predominantly physical forms of traditional bullying. The findings point to the importance of a cross-contextual perspective in studies on stability of bullying victimization.     

Exposure to parental and community violence and the relationship to bullying perpetration and victimization among early adolescents: A parallel process growth mixture latent transition analysis

This study examined heterogeneity in parental and community violence exposure during middle school and its association with bullying perpetration and victimization in high school. Youth (N = 1,611) in four Midwestern middle schools participated. Parallel process growth mixture latent transition analysis was used to understand how trajectory profiles of middle school violence exposure was associated with high school bullying profiles. Impulsivity, depression, school belonging, and delinquency were assessed as moderators of the transition probabilities. A three class solution was found for violence exposure: decreasing parental violence/increasing community violence (n = 103; 6.4%), stable high parental violence and low community violence (n = 1,027; 63.7%), and increasing parental violence and stable high community violence (n = 481; 29.8%). Similarly, a three class solution was found for high school bullying: High Bullying Perpetration and High Victimization class (n = 259; 16%), Victimization only (n = 1145; 71%), and low all class (n = 207; 13%). The largest proportion of youth transitioning into the high bullying and high victimization class were from the decreasing parental violence/increasing community violence. Depression, impulsivity, school belonging, and delinquency all had various moderating effects on transition probabilities. Our findings make it apparent that early forms of parental and community violence are associated with aggressive behaviors and experiences with victimization during high school. Prevention and intervention efforts should target individuals who display early and chronic patterns of exposure to violence as these individuals have the greatest risk of later aggressive and victimization in high school.     

Emotional display rules and emotion self‐regulation: Associations with bullying and victimization in community‐based after school programs

We explored linkages among different components of emotional competence and bullying and victimization in children enrolled in community after school programs. Seventy‐seven children were recruited from after school programs and their display rule knowledge for sadness and anger was evaluated. Their emotion self‐regulation skills and bullying experiences were also assessed. Knowledge of display rules for sadness was a negative predictor of physical victimization whereas emotional lability/negativity was positively related to bullying. Boys bullied more than girls and family income was negatively related to bullying and emotional lability/negativity and positively associated with emotion self‐regulation. Emotion self‐regulation mediated the relation between family income and bullying. Analyses also suggested that bullies and bully‐victims had poorer emotion self‐regulation skills than non‐bullies/victims or victims. Copyright © 2010 John Wiley & Sons, Ltd.     

Social self‐esteem and self‐reported bullying behaviour among adult prisoners

This paper addresses how social self‐esteem relates to self‐reported bullying behaviour among adult prisoners. It explores both level of self‐esteem and participants’ certainty of their self‐esteem. A total of 502 adult prisoners (285 men and 217 women) completed a self‐report behavioural checklist (Direct and Indirect Prisoner Behaviour Checklist) [Ireland JL. 1999. Aggres Behav 25:162–178] that addressed the level of bullying behaviour at their present institution. Prisoners also completed a questionnaire that measured social self‐esteem (Texas Social Behaviour Inventory) [Helmreich R, Stapp J. 1974. Bull Psychonomic Soc 4:473–475]. Four categories of prisoners were compared: bullies, victims, those who reported both bullying others and being victimised themselves (bully/victims), and those who were not involved in bullying behaviour. There were no significant differences among bully categories in total self‐esteem scores. Men reported significantly higher levels of self‐esteem than did women. There were no significant sex or bully category differences in certainty of self‐esteem. Self‐esteem was found to include a number of individual components that differed between the sexes. The findings are discussed, and directions for future research are suggested. Aggr. Behav. 28:184–197, 2002. © 2002 Wiley‐Liss, Inc.     

Associations between adults' recalled childhood bullying victimization,current social anxiety,coping, and self-blame: evidence for moderation and indirect effects

Abstract

Prior studies have shown that bullying victimization is common during childhood and may have negative effects over the short term. Evidence is also emerging that childhood bullying victimization in the form of teasing may precipitate social anxiety in adulthood. The present study extended the field by testing for associations between adults' recall of four common subtypes of childhood bullying victimization and their current social anxiety. It also provided the first test of whether coping moderated those associations, if they were indirect effects through self-blame, and if sex differences existed. Data were collected from 582 students aged 23+ years at two universities in the UK. Collectively, and for social exclusion and relational victimization uniquely, the subtypes of bullying victimization did predict social anxiety. Evidence for hypothesized moderation and indirect effects was obtained but these varied by subtype of victimization (but not sex). The theoretical and practical implications of these results were discussed.     

Neuroanatomy of childhood disruptive behavior disorders

Our aims were to (1) examine possible neuroanatomical abnormalities associated with the Disruptive Behavior Disorders (DBDs) as a group and (2) assess neuroanatomical anomalies specific to each DBD (i.e., conduct disorder [CD] and oppositional defiant disorder). Cortical thickness analysis and voxel-based morphometry were analyzed in 47 8-year-old boys (22 DBDs with and without CD and/or ODD and 25 healthy controls) from Magnetic Resonance Imaging brain scans. DBD symptoms were assessed using the Dominic-R. In DBD subjects relative to controls, we found (1) a decreased overall mean cortical thickness; (2) thinning of the cingulate, prefrontal and insular cortices; and (3) decreased gray matter density (GMd) in the same brain regions. We also found that scores on the Dominic-R were negatively correlated with GMd in the prefrontal and precuneus/superior temporal regions. There was a subdiagnostic main effect for CD, related to thinning of the middle/medial frontal, and for ODD in the left rectal/orbitofrontal. Findings suggest that thinning and decreased GMd of the insula disorganizes prefrontal circuits, diminishing the inhibitory influence of the prefrontal cortex on anger, aggression, cruelty, and impulsivity, and increasing a person's likelihood of aggressive behavior. These findings have implications for pathophysiologic models of the DBDs, their diagnostic classification system, and for designing more effective intervention programs.     

Cyber bullying among children with neurodevelopmental disorders: A systematic review

Children and young adults with neurodevelopmental disorders (ND) are at increased risk of bullying compared to typically developing peers. It is still unclear to what extent they are involved in cyber bullying. This systematic review aimed at studying the prevalence of cyber bullying as perpetrators, victims, or both (“bully-victims”) among students with ND in a school setting and in need of special education. The Web of Science, Scopus, ERIC, PsycINFO, PubMED, and Cochrane databases were searched including a manual search of reference lists, until February 24, 2018. Eight studies conducted in Europe, North America, the Middle East, and Australia were included reporting a prevalence of cyber-victimization among students with ND of 0%–41%, a prevalence of cyber-perpetration of 0%–16.7%, and a prevalence of bully-victims of 6.7%. Three out of five studies using control groups showed that students with ND might be more involved in cyber bullying overall compared to typically developing students. Students in segregated school settings report slightly higher prevalence rates of cyber bullying compared to students with ND in inclusive school settings, especially among girls. When comparing prevalence rates among studies using the same definition, we found similar prevalence rates. There was a tendency towards students with ND being more involved in cyber bullying compared to typically developing students, but this needs to be confirmed in future studies that should include control groups with typically developing students as well as validated and standardized measurements of cyber bullying and ND diagnoses.     

Cyber victimization and adolescent self‐esteem: The role of communication with parents

Internet use has increased rapidly in recent years, and has inevitably led to some negative outcomes, notably cyber bullying and cyber victimization. The purpose of this study was to examine the effects of cyber victimization and parent–adolescent communication on self‐esteem, and the moderating role of parent–adolescent communication in the relationship between cyber victimization and self‐esteem among Turkish adolescents. The participants were 337 adolescents with a mean age of 16.37, (SD = 0.89). The results of hierarchical regression analysis reveal that self‐esteem was predicted negatively by cyber victimization, but positively by mother–adolescent communication. Results also indicate the moderating roles of parent–adolescent communication in the links between cyber victimization and self‐esteem. The findings indicate a need to consider the parent–adolescent relationship while working with victimized youth, and the implications for research and practice are discussed.     

Mindfulness,impulsivity, and moral disengagement as parameters of bullying and victimization at school

The aim of the present study was to examine the existing association between mindfulness, impulsivity, moral disengagement, and bullying experiences at school. Longitudinal data were collected in three points in time (T1, T2, T3) with 6 months interval between them. Participants were 558 adolescents attending secondary schools in Cyprus, with their ages ranging from 14 to 17 years (M = 15.3; standard deviation = 0.69). Through structural equation modeling, it was found that mindfulness at T1 had a significant negative effect on both impulsivity and moral disengagement at T2 and these, in turn, had a positive effect on bullying and victimization at T3. Thus, mindfulness had an indirect effect on both bullying and victimization, fully mediated by impulsivity and moral disengagement.
