The Longitudinal Role of Self-Concept Clarity and Best Friend Delinquency in Adolescent Delinquent Behavior

Adolescence tends to be characterized by a temporary peak in delinquent behavior, and friends in particular play a key role in the initiation and the development of delinquency. However, adolescents differ in their susceptibility to friends' influence on delinquency. Especially adolescents who are less certain about who they are might show more delinquent behavior, and might be more susceptible to their friends' behaviors, as friends are also crucial for adolescents' identity formation. In addition to examining the main effects of best friend's delinquency and self-concept clarity on the development of adolescents' delinquency, the current study scrutinized whether self-concept clarity moderated the longitudinal association between adolescents' and their best friends' self-reported delinquent behavior. The current study examined whether best friend delinquency and adolescent self-concept clarity were related to the development of adolescents' delinquency, and whether self-concept clarity moderated the relation between adolescent and best friend delinquency. Dutch adolescents (N=497, M-age Wave 1=13 years, 287 boys) and their best friends participated across six annual waves. Both adolescents and best friends reported on their delinquency and adolescents reported on their self-concept clarity. Adolescent delinquency linearly declined, and although adolescents' and best friends' delinquency levels were related, changes in delinquency of adolescents and best friends were not. Adolescents low on self-concept clarity reported higher levels of delinquency. Self-concept clarity also moderated the relation between adolescent and best friend delinquency levels, with stronger relations observed for adolescents with lower self-concept clarity. Future research should examine the protective role of self-concept clarity not only against delinquent behavior, but also against susceptibility to peer influence

Classroom Size and the Prevalence of Bullying and Victimization: Testing Three Explanations for the Negative Association

Classroom size - i.e., the number of students in the class - is a feature of the classroom environment often found to be negatively related to bullying or victimization. This study examines three possible explanations for this negative association: (a) it is due to measurement effects and therefore only found for peer-reports (Hypothesis 1), (b) bullying perpetrators are more popular and have more friends in smaller classrooms (Hypothesis 2), (c) targets of bullying are more popular and have more friends in larger classrooms (Hypothesis 3). Multilevel regression analyses were conducted on a sample from Austria (1,451 students; Mage = 12.31; 77 classes) and a sample from the Netherlands (1,460 students; Mage = 11.06; 59 classes). Results showed that classroom size was negatively associated with peer-reported bullying and victimization in both samples, and with self-reported bullying and victimization in the Dutch sample only, suggesting partial support for Hypothesis 1. Students high in bullying were found to be more popular in smaller than in larger classrooms in the Austrian sample. The negative link between victimization and popularity was found to be stronger in smaller classrooms than in larger classrooms in the Dutch sample. However, classroom size was not found to moderate links between bullying or victimization and friendship in either sample. Hypotheses 2 and 3 were supported, but only for popularity and in a single sample. Further research is needed to better understand the higher prevalence of bullying found in smaller classrooms in many studies

Development of aggression subtypes from childhood to adolescence:a group-based multi-trajectory modelling perspective

The persistence of elevated subtypes of aggression beginning in childhood have been associated with long-term maladaptive outcomes. Yet it remains unclear to what extent there are clusters of individuals following similar developmental trajectories across forms (i.e., physical and indirect) and functions (i.e., proactive and reactive) of aggression. We aimed to identify groups of children with distinct profiles of the joint development of forms and functions of aggression and to identify risk factors for group membership. A sample of 787 children was followed from birth to adolescence. Parent and teacher reports, and standardised assessments were used to measure two forms and two functions of aggressive behaviour, between six and 13 years of age along with preceding child, maternal, and family-level risk-factors. Analyses were conducted using a group-based multi-trajectory modelling approach. Five trajectory groups emerged: non-aggressors, low-stable, moderate-engagers, high-desisting, and high-chronic. Coercive parenting increased membership risk in the moderate-engagers and high-chronic groups. Lower maternal IQ increased membership risk in both high-desisting and high-chronic groups, whereas maternal depression increased membership risk in the high-desisting group only. Never being breastfed increased membership risk in the moderate-engagers group. Boys were at greater risk for belonging to groups displaying elevated aggression. Individuals with chronic aggression problems use all subtypes of aggression. Risk factors suggest that prevention programs should start early in life and target mothers with lower IQ. Strategies to deal with maternal depression and enhance positive parenting while replacing coercive parenting tactics should be highlighted in programming efforts

School Bullies' Intention to Change Behavior Following Teacher Interventions: Effects of Empathy Arousal, Condemning of Bullying, and Blaming of the Perpetrator

This study examines how bullies' perceptions of how they were treated by a teacher (or other school personnel) during discussions aimed at putting an end to bullying influenced their intention to change their behavior. After each discussion, which took place as part of the implementation of an anti-bullying program, bullies anonymously reported the extent to which they felt that the teacher aroused their empathy for the victim, condemned their behavior, or blamed them. Half of the schools implementing the program were instructed to handle these discussions in a confrontational way-telling the bully that his behavior is not tolerated-while the other half were instructed to use a non-confronting approach. Schools were randomly assigned to one of the two approaches. A total of 341 cases (188 in primary and 153 in secondary schools) handled in 28 Finnish schools were analyzed. Regression analyses showed that attempts at making bullies feel empathy for the victim and condemning their behavior both increased bullies' intention to stop. Blaming the bully had no significant effect. Bullies' intention to change was the lowest when both empathy-arousal and condemning behavior were low. The effects of empathy arousal were stronger when condemning the behavior was low (and vice versa), suggesting that teachers tackling bullying should make sure to use at least one of these strategies. When choosing not to raise the child's empathy, clear reprobation of the behavior is key

The Healthy Context Paradox: Victims’ Adjustment During an Anti-Bullying Intervention

This study investigated the “healthy context paradox”: the potentially adverse effects of school anti-bullying norms on victims’ psychological (depression, social anxiety, and self-esteem) and school adjustment. Based on the person-group (dis)similarity model, social comparison theory, similarity attraction in friendship formation, and attributional theory, it was hypothesized that the emotional plight of victims is intensified in intervention schools with a visible, school-wide anti-bullying program, as compared with victims in control schools with “a care as usual” approach. Longitudinal multilevel regression analyses were conducted on Randomized Controlled Trial data from the Dutch implementation of the KiVa anti-bullying program (baseline and 1-year follow-up data on 4356 students from 245 classrooms in 99 schools, 68% intervention students, 49% boys, 9–10 years-old). The findings revealed that—despite the overall success of the intervention—those who remained or became victimized in intervention schools had more depressive symptoms and lower self-esteem after being targeted by the intervention for 1 year, compared to those who remained or became victimized in control schools. These effects were not found for social anxiety and school well-being. The findings underscore the importance of individual × environment interactions in understanding the consequences of victimization and emphasize the need for adults and classmates to provide continuing support for remaining or new victims who are victimized in schools that implement anti-bullying interventions
