This study used daily experimental data from smart bands worn by 142 respondents to investigate the relationship between the number of minutes slept and self-reported mood. The results showed that more minutes of sleep were associated with improved mood. Time preferences, altruism, and trust were also associated with mood. Finally, our analysis…

Background: We aimed to characterize relationships between delayed high school start time policy, which is known to lengthen school night sleep duration, and patterns in activity outcomes: physical activity, non-school electronic screen time (non-schoolwork), and sports and extracurricular activity among adolescents. Methods: We used data from the…

The purpose was to understand college students' motivations for the use and discontinued use of fitness related technology (FRT) in relation to their physical activity behaviors. Participants: Participants were undergraduate students (n = 22) who were eligible if they were between 18-24 years of age (emerging adulthood) and current or previous…

School-based physical activity (PA) interventions stand out as a highly valued knowledge technology in relation to attempts to promote daily physical activity (DPA) among school youth. The purpose of the paper is to explore technologies of knowledge that guide school-based PA interventions in lower secondary schools and discuss their power-related…

Objective: Examine effects of self-affirmation on university students' processing of health risk messages related to sedentary behavior. Participants: Eighty-eight students from a Canadian university (females = 53; males = 35; M[subscript age] = 21.74, SD = 5.36) participated during the 2018-2019 academic year. Methods: Participants were…

Exercise is necessary for healthy living, yet individuals with intellectual disability (ID) remain strikingly inactive compared with nondisabled peers. To improve this outcome, individuals with ID can exercise independently by self-instructing. Self-instruction is considered a pivotal skill once it generalizes to untrained stimuli. This study used…

Introduction: The COVID-19 pandemic had implications on students' life. This study aims to identify positive and negative effects of COVID-19 pandemic on students' life habits with the final goal to promote their general wellbeing. Methods: An online questionnaire was administered to Greek undergraduate and graduate college students during the…

Objective: To understand how competence, self-efficacy, enjoyment and motivation relates to physical activity behavior during transition from school to university. Participants: Health science students (n = 558) studying first year biology at an Australian university. Methods: Cross-sectional correlational survey design using five self-report…

This empirical cross-sectional study explored the effect of chronotypes on classroom behaviour. One hundred and forty young Portuguese children, from 1st to 4th grades, were examined regarding their chronotype and disruptive behaviours occurring in the classroom. Three groups of chronotypes (i.e., morning, intermediate and evening) were…

For undergraduate students, excessive screen time is associated with poorer mental health and greater perceived stress. Objective: The purpose of the present investigation was to determine the potential moderating influence of physical activity and sleep on the relationship between screen time and stress. Participants & Methods: A…

This article discusses concepts related to character strengths and positive youth development and how these ideas can be applied to improve outcomes among gifted young people. A theory with roots in public health, The Theory of Triadic Influence (TTI), is discussed with examples applied to gifted populations. Practitioners and researchers from…

Lifestyle risk behaviours--physical inactivity, poor diet, poor sleep, recreational screen time, and alcohol and tobacco use--collectively known as the "Big 6" emerge during adolescence and significantly contribute to chronic disease development into adulthood. To address this issue, the Health4Life program targeted the Big 6 risk…

Health behaviors established during college years are typically carried on into adulthood; however, many college students are not meeting physical activity guidelines. In addition, sociodemographic and environmental factors impact exercise motivation and physical activity; yet, only limited research has compared motivations and behaviors between…

Objective: This study examined the unique and interactive effects of PA volume and within-person fluctuations in PA volume (i.e., intraindividual variability in PA volume; PA-var) on preschoolers' (N = 141; 47.5% girls) ADHD symptoms. Method: Preschoolers wore accelerometers during the school day over a 2-week period. Teachers reported on…

Objective: Physical activity (PA) declines during the transition to university. Identifying contributing factors is imperative. Participants: Participants were first-year undergraduate students (N = 283). Methods: Participants completed validated surveys. Participants were categorized as meeting PA guidelines or not meeting PA guidelines.…
