Based on ecological systems theory and the genetic and environmental research paradigm, the current study explored the effect of school interpersonal relationship quality (peer and teacher-student) on adolescent depression and the role of perceived stress and the OXTR gene. Based on the statistical power of previous G*E interaction studies, A…

Throughout adolescence, both sleep and emotion regulation abilities undergo significant developmental changes. The maturational systems that govern sleep and emotion regulation are closely intertwined leading many researchers to posit a mutually reinforcing relationship. Although there is support for a bidirectional relationship among adults,…

This study proposes a revision (R) of the Center for Epidemiologic Studies Depression Scale for youth with ID (CESD-ID) in English and French. 346 youth (36.02% girls) with mild (51.26%) and moderate (48.78%) ID (11-22 years; M = 15.69), enrolled in secondary schools in Canada (French-speaking; n = 115), and Australia (English-speaking; n = 231),…

Pain and depressive symptoms are common reasons for adolescents to contact the school nurse. The aim was to describe the prevalence of pain (headache, abdominal pain, and back pain) and depressive symptoms among adolescents and to examine whether there is an association between pain and depressive symptoms. This cross-sectional survey included…

Background: Transgender and nonbinary (TNB) students commonly experience identity-based harassment, which is associated with poorer mental health, and TNB students of color may experience harassment targeting gender, race/ethnicity, and other identities. Applying an intersectional lens to minority stress theory suggests that different forms of…

This paper reports on a mathematics outreach programme, 'Bridging KS5 to University', which offered video materials to students aged 16+ during the school closures in spring/summer 2020 in Wales. The 13 videos, provided by the Further Mathematics Support Programme in Wales, ranging from 20 to 50 min long, included activities and exercises…

Community violence exposure is associated with increased depressive symptoms in adolescents. This study examined whether coping style moderates this relationship over time. Eighty-four low-income, urban adolescents (M[subscript age] = 13.36, 50% female, 95% African American) participated in two waves of a longitudinal study. Youth reported on…

Sociological research has demonstrated a link between moving during adolescence and depressive symptoms. In addition, research has documented an inverse association between social support and depressive symptoms. One of the consequences of moving during adolescence is the disruption of social support systems. This suggests that social support may…

The present study examined how teachers respond to ethnic-victimization, and whether teachers' responses buffer the effect of such aversive encounters on immigrant youth's psychological adjustment. The sample included youth of immigrant background residing in Sweden (N = 423; M[subscript age] = 13.19, SD = 0.51; 44% girls), and their head class…

Background: According to Self-Determination Theory, teachers and sport coaches can differ in the motivating style they rely upon to motivate young people. When endorsing an autonomy-supportive motivating style, instructors try to identify, vitalize, and nurture youngsters' inner motivational resources. In contrast, instructors with a dominant…

Depressive symptoms, somatic complaints, and circulating levels of inflammatory biomarkers interleukin-6 (IL-6) and C-reactive protein (CRP) were examined as correlates of social and physical peer victimization in an ethnically diverse sample of adolescents (N = 91) using a multi-informant approach. Hierarchical regression analyses indicated that…

Drawing upon a sample of 772 migrant children and their parents in Shanghai, China, this study used an ecological framework to investigate how social capital embedded in a range of social contexts (i.e., family, school, peer, and community) influenced the psychosocial adjustment of Chinese migrant children. Using structural equation modeling with…

Adolescent clinical and subclinical depression has a significant negative impact on adolescents well being, school performance and consequently produces maladaptive outcomes in terms of subsequent education and occupational functioning. This research is a part of a larger research project with a focus on clinical and subclinical depression during…

Background: Knowledge about the beneficial role of physical activity (PA) for health and school performance is growing. Studies investigating the link between PA and school absenteeism due to illness are lacking. Therefore, we investigated associations between habitual PA and school absenteeism due to illness in adolescents and explored whether…

Although early sexual initiation has been linked to negative outcomes, it is unknown whether these effects are causal. In this study, we use propensity score methods to estimate the causal effect of early sexual initiation on young adult sexual risk behaviors and health outcomes using data from the National Longitudinal Study of Adolescent to…
