We examined the moderating effect of gender on witnessing bullying, defending, and internalizing symptoms among sixth-grade students at one middle school in the northwestern United States. Results indicated that for females, witnessing bullying was positively associated with depressive symptoms and social anxiety, whereas for males, defending was…

This study examines the connections between children's sleep, stress, depression, and internet use. Parents believe that sleep effectively reduces children's stress, while children instead insist that internet use is effective for reducing their stress. Based on that argument, this study has three purposes: to examine whether sleep or internet use…

The hypothesis that the concurrent associations between friendship features and friendship satisfaction are moderated by security-related experiences within the family was examined with two sets of analyses conducted with a sample of fifth- and sixth-grade students (M = 10.87, SD = 0.73, range 10-13 years). The main hypothesis of the study was…

Children's academic performance has an effect on, and is affected by, their social experiences and psychological adjustment. This study aims to investigate the longitudinal relations among academic achievement, peer victimization, and depression in Chinese children. A sample of 1045 students (639 boys, 406 girls, mean age = 9 years 4 months)…

This research aimed to establish the relationship between the social exclusion perceived by gifted and talented students and their sense of humor. Besides, the goal was to evaluate the relationship between the variables of the use of humor, the process of coping through a sense of humor, and the appreciating humor in cases of ignoring and avoiding…

The purpose of this study was to examine how two coping strategies together moderate the relationship between peer victimization and adjustment among young adolescents. Sixth-grade adolescents from California, Oregon, and Wisconsin (N = 1,058) self-reported peer victimization, depressive symptoms, and their utilization of social support seeking…

This study examined the mediating role of self-esteem on the relationship between parental attachment security and social anxiety in children, separating maternal and paternal attachment. A total of 298 Korean children in 5th and 6th grade participated. Using structural equation modeling, results showed that the research model fit the data well…

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…

In the current study, associations between individual and friends' direct and indirect aggression and depressive problems were examined. It was expected that social status would moderate these associations such that low-status preadolescents would be more similar to their unilateral friends with regard to indirect, but not direct, aggression.…

Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

Youth with ADHD are more at-risk for peer victimization than their typically developing peers, and may not be benefiting from current interventions. Thus, we sought to examine risk (i.e., anxiety, depression, and forms of aggression) and protective (i.e., social skills and social acceptance) factors for peer victimization in this group.…

Designing learning experiences that support the development of coherent understanding of complex scientific phenomena is challenging. We sought to identify analytics that can also guide such designs to support retention of coherent understanding. Based on prior research that distributing study of material over time supports retention, we explored…

Background: Rational numbers are of critical importance both in mathematics and in other fields of science. However, they form a stumbling block for learners. One widely known source of the difficulty learners have with rational numbers is the natural number bias, that is the tendency to (inappropriately) apply natural number properties in…

The present study examined associations between effortful control, a trait marker of self-regulation, adaptive hypothalamic-pituitary-adrenal (HPA) system functioning (as reflected by the cortisol awakening response [CAR]), and concurrent and longitudinal depressive problems, in a sample of preadolescent Latino youth (N = 119, mean age = 11.53…

Emotional eating, defined as eating in response to affect, may increase during early adolescence, a time of heightened emotionality and increased prevalence of emotional disorders. We investigated change in emotional eating, while also testing the influence of social-emotional risk factors. Study participants (N = 379, mean age [M[subscript age]]…
