This study examined whether adolescent students' externalizing behavior and prosocial behavior affects their academic achievement (i.e., school grades and standardized test scores) in two major academic domains (i.e., mathematics and German) over and above well-established determinants of school achievement (i.e., prior achievement, intelligence,…

In this study, we investigate how the accumulation of stressful life events and chronic stressors experienced in adolescence predict young adults' future self-identification (i.e., connectedness, vividness, and valence of the future self) in a sample of 1482 Swiss youth. Furthermore, we investigate future self-identification as a source of…

This study examined the links between seven specific mechanisms of moral disengagement and indirect bullying, direct bullying, and pro-aggressive bystander behavior. In addition, the moderating role of gender on these associations was examined. Participants were 317 Swedish students in Grades 4 to 8 (X-bar[subscript age]=12.6, SD = 1.35; 62%…

This study examined relations between intentional self-regulation (ISR) and executive functions (EFs) among 84 Icelandic youth in Grade 6 (mean age 11.7 years; 51% girls) and their contributions to healthy and problematic outcomes a year later. ISR was indicated by the Selection, Optimization and Compensation model (SOC) and Self-Regulated…

This longitudinal study covering two educational transitions examined 1,821 Finnish students' participation in and identification with school and their associations with students' academic achievement and truancy. The students were surveyed (a) at the end of primary school, (b) at the beginning of lower secondary school, (c) at the end of lower…

The present study investigated the stability of friendship nominations over the course of a school year as a function of early adolescents' and their classroom best friends' internalizing symptoms (i.e., depression, anxiety, and somatization). Sample consisted of 156 early adolescents (57.1% female; X-bar age = 12.62; SD = 0.62) involved in 78…

We hypothesized that in adolescence, maladaptive narcissism interacts with low self-esteem to predict a preoccupied attachment style ("attachment for self-affirmation hypothesis"), and with high self-esteem to predict an avoidant attachment style ("attachment for self-enhancement hypothesis"). We expected gender differences in…

Research has demonstrated that adolescents regularly use Internet pornography. This two-wave panel study aimed to test an integrative model in early adolescent boys (M[subscript age] = 14.10; N = 325) that (a) explains their exposure to Internet pornography by looking at relationships with pubertal timing and sensation seeking, and (b) explores…

This study addresses the interacting effects of classroom cohesion and hierarchy on the relationships between victimization and aggression with peer acceptance and rejection. Classroom cohesion and hierarchy were constructed from friendship nominations. Multilevel analysis conducted in a sample of seventh- and eighth-grade students from the…

The current study investigates the longitudinal association, across a 1-year period, between self-esteem and narcissism with bullying and peer victimization. The sample consisted of 1,416 (50.1% girls) Greek Cypriot early adolescents ("M" age = 12.89) who completed a battery of self-report measures. The small correlation found between…

Early adolescents vary in their susceptibility to peer influence on delinquency. However, it is still less clear which factors explain this variation and how these factors relate to each other. In this study, 10 factors that may moderate peer influence were investigated. A sample of 868 participants was followed across six occasions from seventh…

The purpose of this multiwave longitudinal study was to examine the structure of self-complexity and its relation to depressive symptoms in 276 adolescents (M = 12.55; SD = 1.04). Self-complexity, depressive symptoms, and negative events were assessed during a laboratory assessment at baseline, and then depressive symptoms and negative events were…

This study examined to what extent motives for behavior differentiated between popular, accepted, and rejected adolescents. Based on goal-framing theory, three types of motives were distinguished: hedonic (aimed at short-term gratification), instrumental (aimed at improvement of one's situation), and normative (aimed at acting in accordance with…

Cross-sectional studies have shown a positive association between expressive suppression and depressive symptoms. These results have been interpreted as reflecting the impact of emotion regulation efforts on depression. However, it is also possible that depression may alter emotion regulation tendencies. The goal of the present study was to…

This study examined the behavioral, personality, and communicative predictors of acceptance and popularity in 608 early adolescents. Data were collected with sociometric methods and ratings in 30 sixth-grade classrooms. Hierarchical regressions were run to predict acceptance and popularity from prosocial, antisocial, and withdrawn behavior,…
