Autism has been associated with increased mortality risk among adult populations, but little is known about the mortality risk among children and young people (0-24 years). We used a 15-year nationwide birth cohort study using linked health and non-health administrative data to estimate the mortality risk among Autistic children and young people…

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…

Deconversion is a biographical change in which one goes from claiming adherence to a religion to departing from it. A meaning system model can help us understand the processes through which deconversion occurs. Drawing on that framework, we explored how perceiving hypocrisy in one's religious setting influences adolescent deconversion. Irrational…

The current study investigated the indirect effects of anger on the four forms and functions of relational aggression (i.e., proactive indirect, proactive direct, reactive indirect, reactive direct) through anger rumination in a sample of 1020 Greek adolescents (504 boys). Males used more proactive direct and indirect relational aggression,…

Urban adolescents experience high rates of exposure to community violence, which is associated with sleep problems. However, less is known about the prospective relationships between community violence exposure and sleep problems across adolescence. This study investigated reciprocal relationships between community violence exposure and sleep…

A moderated mediation analysis was performed on 3,600 (1,829 boys and 1,771 girls) adolescents from the Longitudinal Study of Australian Children (LSAC). Results from a path analysis revealed that child self-efficacy mediated the relationship between mother control self-efficacy and child delinquency in girls but not in boys and that it mediated…

Structural equation modelling (SEM) with longitudinal survey data was used to test a proposed developmental model of the association of family income (with children aged 6-9) to parent behaviours (for children at 10 years of age) and adolescent cognitive achievement and behaviour problems (at age 15). Data from the Child Development Supplement and…

Genetic and environmental factors account for variability in a range of developmental outcomes, including socioeconomic status (SES). The challenge is to find ways to incorporate genetic information based on studies using biologically related family members (i.e., studies not involving twins). To address this issue, we computed polygenic scores…

Although there have been calls to expand mentoring as way to redress the growing problem of economic immobility in the United States, no study to date has directly examined whether mentoring and economic mobility are related. Using multiple waves of data from the National Longitudinal Study of Adolescent Health and employing a propensity score…

The growth of reading and cognitive skills is crucial for children's development. This study examined the utility of incorporating a cognitive framework for reading in intervention design among struggling readers receiving National Institute for Learning Development (NILD) Educational Therapy® over a 3- to 5-year period. Evidence from this…

This paper examines ideas about mental health, wellbeing and school education to illustrate important issues in the relationship between mental health and education. The COVID crisis has amplified the pre-existing mental health problems of children and young people in England and recognition of the opportunities in schools to address these. The…

Adolescence is a period of dramatic change that necessitates using skills and strengths to reduce physical aggression and increase happiness. This study examined the multiple facets of self-control skills in achieving both goals simultaneously, in a sample of 248 Arab adolescents in Israel. We conceptualized and tested a new multi-mediator model…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

The goal of this article was to examine gender-typed behavior longitudinally and to consider its relationship with sexual orientation in adulthood. Data were from 10,624 respondents who completed Wave 1 (adolescence), Wave 3 (emerging adulthood), and Wave 4 (early adulthood) of the National Longitudinal Study of Adolescent to Adult Health. First,…

Although a considerable body of research has documented the association between victimization experience and adolescent mental health, previous studies have not investigated the mediating effects of personality characteristics such as social competence and self-mastery on the associations between cyberbullying victimization and mental health. This…
