Introduction Physical activity declines during adolescence, with the lowest levels of activity observed among those with disability. Schools are ideal settings to address this issue; however, few school-based interventions have been specifically designed for older adolescents with disability. Our aim is to investigate the effects of a school-based...

Children’s engagement in screen time is a complex issue. While some forms of screen time have consistently been associated with harm, others have been associated with gains, making it difficult to weigh the risks and benefits of use. In this umbrella review, we systematically collate and synthesise meta-analyses examining the effects of screen use...

Teachers’ behaviour is a key factor that influences students’ motivation. Many theoretical models have tried to explain this influence, with one of the most thoroughly researched being self-determination theory (SDT). We used a Delphi method to create a classification of teacher behaviours consistent with SDT. This is useful because SDT-based inter...

Multimedia is ubiquitous in 21st-century education. Cognitive load theory and the cognitive theory of multimedia learning both postulate that the quality of multimedia design heavily influences learning. We sought to identify how to best design multimedia and review how well those learning theories held up to meta-analyses. We conducted an overview...

Background Physical activity is related to many positive health outcomes, yet activity levels of many children are low. Researchers have suggested that family-based interventions may improve physical activity behaviors of both children and their parents. In this study, we evaluated the “Active 1 + FUN” program, which was designed based on tenets of...

Many psychological treatments have been shown to be cost-effective and efficacious, as long as they are implemented faithfully. Assessing fidelity and providing feedback is expensive and time-consuming. Machine learning has been used to assess treatment fidelity, but the reliability and generalisability is unclear. We collated and critiqued all imp...

Background Reliable estimates of habitual sleep, physical activity, and sedentary time are essential to investigate the associations between these behaviours and health outcomes. While the number of days needed and hours/day for estimates of physical activity and sedentary time are generally known, the criteria for sleep estimates are more uncertai...

Importance Cardiorespiratory fitness is an important marker of childhood health and low fitness levels are a risk factor for disease later in life. Levels of children's fitness have declined in recent decades. Whether school-based physical activity interventions can increase fitness at the population level remains unclear. Objective To evaluate th...

Despite well-established benefits, the majority of young people around the globe are not sufficiently active. In many countries, including Australia, physical activity (i.e. physical education and school sport) is not mandatory in the final two years of high school (i.e. senior school years). The aim of this study was to assess the impact of a time...

Article
School-based interventions can increase young people's physical activity levels, but few are implemented at-scale (i.e., the expanded delivery of efficacious interventions under real-world conditions into new/broader populations). The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework can be used to describe the exte...

Background: Excessive engagement with digital screens is harmful to children's health. However, new evidence suggests that exposure at moderate levels may not be harmful and may even provide benefit. Therefore, our objective was to determine if there are curvilinear relationships between different types of screen time and a diverse set of outcomes...
Article
Full-text available
Objective: Physical self-concept and moderate-to-vigorous physical activity (MVPA) are fundamental components of adolescents' health and well-being. Previous research suggests that physical self-concept and MVPA share reciprocal relations whereby physical self-concept is both an antecedent (i.e., self-enhancement) and outcome (i.e., skill developm...
