The literature on school climate, albeit vast, is limited by a scarcity of longitudinal research. This two-wave longitudinal study aims to bridge this gap by (a) assessing, over two school years, the changes in students' perceptions of several dimensions of school climate and (b) exploring the reciprocal longitudinal effects of student perceptions…

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 analyzed developmental changes in outsider behavior, testing whether the likelihood that it turns into bullying or defending over time depends on the individual proneness to feel shame or guilt. Participants were 155 preadolescents (72 boys and 83 girls; [X-bar][subscript age] at T1 = 10.74 years). Bullying, defending, and outsider behaviors…

This study investigated early adolescents' psychophysiological response to a school-related stressor (SRS) as indexed by heart rate variability and examined the unique and interactive effects of heart rate variability and temperament on academic achievement. A total of 91 seventh graders watched an SRS video-clip while their heart rate variability…

This study investigated the links between students' behavioral problems, student--teacher conflict, and students' involvement in bully, victim, and bully/victim roles in adolescence. The role of student-teacher conflict as moderator of the association between students' behavioral problems and their involvement in each bullying role was examined.…

For years educators have attempted to identify the effective predictors of scholastic achievement and several personality variables were described as significantly correlated with grade performance. Since one of the crucial practical implications of identifying the factors involved in academic achievement is to facilitate the teaching-learning…

This study investigated the relationships between three psychopathic dimensions (callousness/unemotionality, grandiosity/manipulation, and impulsivity/irresponsibility) and reactive and instrumental aggression in a community sample of early adolescents (N = 243, age M = 12.29, SD = 1.18). The moderating role of moral disengagement (MD) was also…
