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…

Depressive problems and academic performance, social well-being, and social problems in adolescents are strongly associated. However, longitudinal and bidirectional relations between the two remain unclear, as well as the role of gender. Consequently, this study focuses on the relation between depressive problems and three types of functioning in…

Over the past 25 years, a burgeoning literature has emerged which concentrates on the antecedents, experiences and effects of peer victimisation and bullying in schools. Although many advances have been made in this research area, there remain relatively few research papers in the academic literature that discuss the complexities of research (a)…

The present study examined the associations among family connectedness, ethnic identity, and ethnic engagement on changes in well-being over time for the understudied population of Ma¯ori (indigenous New Zealand) youth. Data were collected as part of a longitudinal study of youth connectedness in New Zealand using self-report measures at 3…

Children chronically exposed to stress early in life are at increased risk for maladaptive outcomes, though the physiological mechanisms driving these effects are unknown. Cortisol reactivity was tested as a mediator of the relation between prenatal substance exposure and/or early adversity on adaptive and maladaptive outcomes. Data were drawn…

As a way to raise attainment, schools are encouraged to form ability groups across classes for particular subjects. There is limited evidence however about the relationship between setting and primary school children's characteristics and how teachers perceive them. The aim of this study was to investigate associations between set positioning for…

Objectives: To estimate the impacts of Sweden's Contact Family/Person Program (CFPP) for older children on participants' long-term outcomes related to mental health problems, illicit drug use, public welfare receipt, placement in out-of-home care, educational achievement, and offending. Method: We analyzed longitudinal register data on more than…

Dysregulated cortisol is a risk factor for poor health outcomes. Children of distressed mothers exhibit dysregulated cortisol, yet it is unclear whether maternal distress predicts cortisol activity in later developmental stages. This longitudinal study examined the prospective relation between maternal distress during late childhood (9-12 years)…

Based on data from a three-year longitudinal study, we assess the effect, according to gender, of emotional psychopathology in preadolescence on anthropometric and body composition parameters in adolescence (N = 229). Psychopathology was assessed using the "Screen for Childhood Anxiety and Related Emotional Disorders, the Children's…

This paper explores what is perceived and believed to be an ideal ballet body by young ballet dancers. Such bodily belief becomes, in Pierre Bourdieu's terms, a core part of a ballet dancer's habitus. A four year longitudinal, ethnographic, empirical study of the experiences of 12 young ballet dancers, six boys and six girls, aged between 10 and…

Gene-environment studies on adolescents' peer contexts are important for understanding the interplay between biological and social antecedents of adolescent psychopathology. To this end, this study examined the roles of serotonin transporter (5-HTTLPR) and preadolescent and early adolescent peer rejection and acceptance, as well as the interaction…

There is widespread international concern about post-16 participation rates in science, with women's under-representation constituting a particular issue. This paper contributes to these debates through a novel, critical examination of the role of masculinity within boys' negotiations of science aspirations. Drawing on a UK longitudinal study of…

Adolescence is a period of radical normative changes and increased risk for substance use, mood disorders, and physical injury. Researchers have proposed that increases in reward sensitivity (i.e., sensitivity of the behavioral approach system [BAS]) and/or increases in reactivity to all emotional stimuli (i.e., reward and threat sensitivities)…

This study examined the prevalence and chronicity of sleep problems in children who manifest problems believed to be typical of Autism Spectrum Disorders (ASD). Using data from a longitudinal total population study, symptoms of ASD, insomnia and potential explanatory factors were assessed at ages 7-9 and 11-13. Children were included in a group…

The longitudinal relations of emotion regulation profiles to temperament and adjustment in a community sample of preadolescents (N = 196, 8-11 years at Time 1) were investigated using person-oriented latent profile analysis (LPA). Temperament, emotion regulation, and adjustment were measured at 3 different time points, with each time point…
