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…

The aim of the current study was to investigate whether the association between parental attachment and externalizing behavior is parallelly mediated by dysfunctional emotion regulation and callous-unemotional traits. The community sample included 296 adolescents (M[subscript age]?=?14.90, SD[subscript age]?=?1.31), who completed the Inventory of…

Much research has been done into the relationship between students' motivation to learn and their basic psychological needs as defined by the self-determination theory (autonomy, competence, relatedness). However, few studies have explored how these psychological needs relate to different types of maladaptive behavior in the classroom. To prevent…

Continual conduct problems from adolescence to adulthood comprise a societal concern. Knowledge of school-related triggers and contributors to persistent conduct problems is important but still limited. We explored the role of schoolwork difficulties and being bullied by peers at school in the development of conduct problems, controlling for…

A major concern for teachers is how to prevent and manage disruptive behaviours. Against this backdrop, there is a need for thorough investigation of pupils' perspectives to better…

Both autonomy and friendship quality have consistently been associated with adolescent adjustment. To date, the potentially moderating role of peer relationships in the context of autonomy achievement has received less attention. The present study used observational and quantitative data, as well as multiple reporters, to examine interactions…

Starting from a person-environment fit framework, this study investigates whether ethnic congruence--the percentage of co-ethnics in a school--relates to school misconduct and whether congruence effects differ between ethnic minority and majority students. Moreover, we investigate whether eventual associations are mediated by friendship…

Values, or the guiding standards of adolescents' lives, influence which behaviors are considered more justified than others. The relationship between values and social behavior has been established across many studies including the relationship of values and aggression. But only a few studies have examined these relationships among youth.…

Data were obtained via the Stockholm School Survey from 41,032 ninth- and eleventh-grade students in the years 2004, 2006, 2008, and 2010. Results showed that students involved in bullying as…

The self-equilibrium hypothesis underlines the importance of having a strong core self, which is defined as a high and developmentally stable self-concept. This study tested this hypothesis in relation to body image (BI) trajectories in a sample of 1,006 adolescents (M[subscript age] = 12.6, including 541 males and 465 females) across a 4-year…

School-related problems such as poor academic performance, truancy, frequent suspensions, and grade repeating have been identified as risk factors for adolescent behavior problems. The purpose of the current study was to examine the effect of school-related factors on violent criminality in adulthood, based on data from the National Longitudinal…

Using a sample of 767 children (403 girls, 364 boys), this study aimed to (a) identify groups with distinct trajectories of peer victimization over a 6-year period from primary school through the transition to secondary school, and (b) examine the associated personal (i.e., aggression or internalizing problems) and familial (family status,…
