Iron is needed for normal development in adolescence. Exposure to individual environmental metals (e.g., lead) has been associated with altered iron status in adolescence, but little is known about the cumulative associations of multiple metals with Fe status. We used data from the 2017-2018 National Health and Nutrition Examination Survey…

Traditionally, children have generally been considered as developmentally immature and unable to experience spirituality. However, more recent studies seem to indicate the opposite.

This study tested an empirical model of the relationship between "Personal Positive Youth Development" (PPYD) and two contextual factors: "Positive Parenting" (PP), and "Perception of the Climate and Functioning of the School" (PcfS). The hypothesis tested was that a positive relationship with parents and a positive…

Academic attainment is a core education policy priority. Wellbeing is recognized as critical for adolescent development, and is linked to academic attainment.

Research shows that peer relationships are associated with students' school adjustment. However, the importance of advantageous and disadvantageous factors for students' educational outcomes may vary by socioeconomic positioning. Drawing on sociometric and register data from a nationally representative sample of Swedish youth (n = 4996, girls 50%;…

The purpose of this study was to address the role of social comparison in determining individual development by exploring the relationship of four types of social comparison with academic persistence-procrastination and subjective well-being among Chinese adolescents (n = 530, M[subscript age] = 14.59) from both variable- and person-centered…

Evidence of their relationship with growth, maturation, and training load is equivocal. The objective of this study was to investigate the effects of these factors on overuse injuries in dance and aesthetic sports. A database search…

Current theories of loneliness posit that biases in social information processing play a key role in the development and maintenance of loneliness. However, this assumption has rarely been tested in longitudinal research in adolescence. The current study concentrated on two constructs associated with such biases, that is, fear of negative…
