Online learning as an emerging learning method has a significant impact on education, which cannot be ignored. This article explores the relationship between engagement (including cognition, behavior and emotion), motivation, environment, and college students' concentration in online learning during the COVID-19 pandemic. A total of 889 college…

This study explores the connections between aspects of the school environment and emotional problems among boys and girls. The sample comprised 2,120 adolescents aged 17 and 18 years, in 129 school classes from 13 upper secondary schools in Trøndelag county, Norway. The response rate was 79%. The girls reported more emotional problems than the…

Based on the "Differential Susceptibility Theory," we examined whether the relationship between pubertal maturation and depressive symptoms can be moderated by individual differences in environmental sensitivity. The current article used the three-wave data collected from Japanese adolescents aged from 12 to 15 years (girls = 111,…

Child physical activity (PA) is influenced by social environment. Self-perception and perception of others' behaviors may impact health behaviors such as PA. This study examines associations between child networks, perception of their own PA and the network's perception of their PA. Children (n = 89, M age = 10.00, SD = 1.34) at a summer care…

The non-cognitive skills self-control and grit are often considered predictors of school performance, but whether this relationship is causal remains unclear. We investigated the causality of this association using a twin design. Specifically, we evaluated the direct impact of self-control and grit on school performance, while controlling for…

Considering that externalising behaviour problems are one of the most prominent psychopathologies, it is important to investigate the interplay of individual and environmental factors that are associated with such behaviours. Although previous literature revealed associations between parenting dimensions, callous-unemotional traits, and…

The onset of behavioral problems in early childhood is associated with an increased frequency of delinquent behavior. A significant amount of youth in the juvenile justice system have histories of mental illness and psychological distress. However, little is known about what factors mediate the relationship between early onset behavioral problems…

This study examined how early adolescents' risk taking propensity and urban stress were linked to their affiliation with risky peers. Participants (n = 297; [X-bar] age = 10.48 years [SD = 0.93 years]; 54% male; 58% Black/African American) completed a brief laboratory-based behavioral risk taking task. They also completed self-report measures of…

Adolescent health has a significant influence as individuals transition to adulthood and can have lifelong effects on well-being. In addition to well-established structural determinants of health such as racism and poverty, proximal determinants of adolescent health illuminate on the health effects of the daily circumstances of adolescents. Guided…

The purpose of this study was to examine the long-term effects of perceived community disorder and social stigma on depressive symptoms among adolescent school dropouts. This study used 2-4 wave data of a Longitudinal Survey and Support Plan for Dropouts. Multivariate latent growth modeling indicated that social stigma was associated with greater…

Background: The leading cause of nonfatal injuries in age group 14-19 is sports injuries. Purpose of the study was to determine the association between intense physical activity and injury and to identify the circumstances and environment in which injuries are most likely to occur. Methods: A prospective cohort study included 698 high school…

This study aimed to understand how the COVID-19 pandemic impacted the stress levels and life satisfaction of individuals with disabilities and what role social support plays in mitigating these impacts. Data from individuals with disabilities (n = 600) were extracted from a larger international cross-sectional survey study. Regression analyses…

Large-scale international studies offer researchers a rich source of data to examine the relationship among variables. Machine learning embodies a range of flexible statistical procedures to identify key indicators of a response variable among a collection of hundreds or even thousands of potential predictor variables. Among these, penalized…

Early childhood education (ECE) institutions may be one place for young children to obtain a significant proportion of their daily physical activity (PA). Even though young children are generally considered to be very active, and recess time is considered an important environmental factor for promoting PA, evidence suggests that young children…

The second to fourth digit (2D:4D) ratio is of interest in autism spectrum disorder (ASD). Studies on the relationship of this ratio with other neurodevelopmental disorders (NDDs) are lacking. Investigating the association between the ratio and NDDs in twins can provide insight into genetic and/or environmental factors driving the ratio. Hand…
