Problematic internet use (PIU) has become a noticeable issue among adolescents, which negatively affects their physical and mental health. Previous research has noted the protective role of school climate in reducing PIU, but the underlying mechanisms need to be further explored. Based on the ecological systems theory, this study focused on the…

Despite research on peer dynamics in mainstream classrooms and in mental health interventions, investigations of peer dynamics in self-contained classrooms for students with emotional and behavioral disorders (EBD) are limited. This study examined the influence of classroom behavior norms on individual behavior in a school for students with…

Starting from observed gender differences in educational effort and because research considers motivation to be a personal student feature, this study had two aims. First, it examined whether autonomous and controlled motivation are shared by students within a school and whether such a motivation culture is associated with the school's student…

This study estimates how students suffering from parental conflicts could affect their classmates in Chinese middle schools. We show that children with quarreling parents are more likely to misbehave. Negative spillovers from these potentially troubled peers concentrate on students from economically disadvantaged families. With greater exposure to…

This is the first systematic review of the school outcome literature for behavior interventions used with middle school students exhibiting disruptive behaviors. A total of 51 investigations (published between 2000 and 2020) including 6,498 students and 264 implementers were coded on four dimensions (i.e., sample, interventions, methodology, and…

Peer affiliation is an important factor in the behavioral trajectories of adolescents, and the effect of peer dynamics on problem behavior is especially salient in the school setting. In this paper, the author presents a cross-sectional evaluation of the link between deviant peer affiliation and school-based problem behavior for middle school…

The aim of the current study was to investigate the relationship between adolescents' social support, their internalising and externalising behaviour problems, and their alcohol consumption. Adolescents attending Grade 7-10 (N = 329), answered questionnaires regarding their perceived social support (from parents, teachers, classmates, and…

Class-wide behavioral interventions are a feasible and effective method to support the behavior of all students. In six peer-reviewed studies, Tootling, a class-wide intervention that combines positive peer reporting with an interdependent group contingency, has increased positive peer reports and academically engaged behavior (AEB), and decreased…

This is the first systematic review of the school outcome literature for behavior interventions used with middle school students exhibiting disruptive behaviors. A total of 51 investigations (published between 2000 and 2020) including 6,498 students and 264 implementers were coded on four dimensions (i.e., sample, interventions, methodology, and…

The current study was designed to evaluate the effects of a tootling intervention, in which students report on peers' appropriate behavior, modified to incorporate ClassDojo technology, on class-wide disruptive behavior and academically engaged behavior. An A-B-A-B withdrawal design was used to evaluate the effects of the intervention in 3…

The problem behaviors exhibited by left-behind children occur within multiple contexts, and are influenced by cumulative risk, including family, peer, and school characteristics; however, little is known about the mediating and moderating mechanisms underlying the relationship between such problem behaviors and cumulative risk. A total of 1,313…

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 (M = 11.21 years) to Grade 10 (M = 16.25 years) provided self-reports of delinquency. Friendships were identified from…

This study is aimed to gain insights into adolescents' classroom peer climate by examining descriptive and status norms of academic and social behaviors. Descriptive norm was assessed as the average score for each behavior and status norm was assessed using the correlation between each behavior and social status within each classroom. Expanded…

This research investigated how the level of disruptive behavior and friend influence on disruptive behavior varies across classrooms in relation to teacher emotional support. Data were collected from 48 fifth- and sixth-grade classrooms (N = 879 students) and included classroom observations at Wave 1 and student reports of their disruptive…

Recent research indicates that the development of antisocial behavior among students is influenced by the behavioral characteristics of their classmates. However, not all peers in a given class may exert the same influence. Thus, we examined the extent to which individual development is predicted by the perceived proportion of all students with…
