This study examined whether social mistrust in early adolescence was general or referent-specific. We used a multi-trait multi-method approach to examine the validity of mistrust measures across social referents (mistrust toward people in general, toward peers, and toward teachers), using questionnaires and an online task. Sixth graders (N = 1243,…

The overall objective of this study was to investigate the longitudinal association between diffusion of responsibility and pro-aggressive bystander behavior across three time points in upper elementary education. This three-wave longitudinal study included 1905 Swedish students who completed a questionnaire in at least one of the three waves: the…

Early adolescence is a critical time for promoting emerging adolescents' positive social skill development and mental well-being. This investigation addresses unique characteristics of these relations by holistically examining how school-based social cohesion and school stress combine to impact peer aggression and prosocial behavior. Using a…

Although previous studies have shown the association between students' perceived teacher procedural justice and their aggressive behaviors, there are still mediating mechanisms that need to be explored to fully understand the relationship. This study proposed a parallel mediation model through both legitimacy of authority and through motivation to…

Attention deficit/hyperactivity behaviors in children are often unnoticed until they reach school age; however, evidence suggests that attention deficit hyperactivity disorder (ADHD) tends to develop at an earlier age. Recent studies also indicate that perinatal maternal mental health is associated with ADHD symptoms in offspring. This study…

This study investigated characteristics associated with two kinds of peer victimization--bullying victimization and adversarial victimization--distinguished by different balances of power between the perpetrator and victim. Specifically, we examined whether bullying victimization (victim has less power than perpetrator) would be experienced to a…

In this study, we identified (1) subgroups of youth during middle childhood who displayed distinct profiles of social emotional learning (SEL) skills including cooperation, prosocial behaviors, work habits, emotion regulation, and self-control; and (2) how these profiles predict longitudinal academic and social functioning during early…

The goal of this study was to assess longitudinal, predictive relationships between community violent crime and reactive and proactive aggression. Community violent crime data were gathered from local law enforcement agencies and combined with an existing dataset of at-risk youth. Aggression was assessed by parents using the Reactive and Proactive…

The goal of this study was to examine the prospective associations of prosocial behavior and aggression with social preference in classrooms and whether these associations were moderated by classroom levels of peer-perceived liking and disliking by the teacher. Participants were 2900 fourth-to sixth-grade students in South Korea (M[subscript age]…

This study examined associations of best friend and peer group aggressive characteristics with students' overt and relational aggression, and whether coolness moderated these associations across the fall and spring of the first year in middle school. Students (N = 174; 57% females) self-reported best friendship and peer group members, as well as…

Prosocial teasing is the positive playful form of relational aggression, and studies have found children engage in playful teasing more often than aggressive teasing. Therefore, understanding the basic characteristics or skills that contribute to the more complex social skill of prosocial teasing is important. The current study focused on the role…

This study explored the relations among peer victimization (i.e., physical, relational, and cyberbullying victimization), learning flow, and academic achievement among elementary school students, using a seven-wave longitudinal design across four consecutive semesters. Participants were 1,440 students from Grades 3 and 4 in China (M[subscript age]…

Socialization among aggressive friends is believed to play a critical role in the development of aggressive behavior. This study examined the moderating effect of norm salience in the classroom on the association between reciprocal friends' and children's own physical, relational, and general aggression. A total of 713 children (M = 10.32 years,…

Introduction: Peer victimization is the experience of being a target of intentional negative or aggressive actions by peers (Card & Hodges, 2008). Peer victimization at school is a growing concern because of its high prevalence rates (Finkelhor et al., 2013) and potential harmful impacts on student mental health and developmental outcomes…

Self-regulation forms the rudiments for children's academic achievement and socialization. Although one's executive control and verbal skills are needed in both of the core aspects for academic performance: processing to regulate one's own learning and behavior, young students' cognitive capacity for that is still immature influencing the…
