PACE Study: School-Based Mindfulness and Compassion Interventions for Children

This study aims to evaluate the effects of three school-based interventions focused on mindfulness, compassion, and social-emotional learning on children's psychological well-being and higher-order cognitive functions. The interventions are delivered in the classroom through structured experiential activities. Children are assessed before and after the interventions using standardized tests and questionnaires measuring attention, executive functions, emotional regulation, mindfulness, self-compassion, and social-emotional skills.

Intervention to Reduce Sedentary Behavior During School Recess Among Adolescents

This cluster randomized controlled trial evaluated the effectiveness of an 8-week, school-based behavioural intervention grounded in the Multi-Process Action Control (M-PAC) framework in promoting interruption of sedentary behaviour during school breaks among adolescents. Twelve primary and secondary schools in China, were recruited and randomly allocated (at the school level) to either an intervention group or a control group to minimise contamination and support pragmatic delivery within the school setting. Schools assigned to the intervention group implemented a multi-component programme comprising educational materials, teacher-delivered guidance, peer reminders, and health lectures, whereas control schools continued their usual routines without receiving intervention materials. The primary outcome was interruption of sedentary behaviour during school breaks assessed using self-reported measures. Secondary outcomes included physical activity levels, emotional and behavioural problems, executive function, and psychological factors related to behaviour regulation, such as motivation, planning, and habit. Findings from this trial are intended to inform the development and implementation of feasible, theory-informed school strategies to reduce sedentary behaviour during school breaks.

School-based Physical Education in Bhutan for Physical Fitness and Socio-emotional Competencies in Adolescents

Despite global evidence supporting the benefits of PE in promoting socio-emotional skills, much of the research has focused on countries where PE is a mandatory part of the curriculum. In contrast, Bhutan's Health and Physical Education (HPE) program is limited, with many schools lacking a structured curriculum and dedicated PE educators. This project aims to evaluate the impact of an enhanced school-based physical education (PE) program on physical fitness, socio-emotional competencies, and well-being among upper primary school students in Bhutan. This project is a methodological collaboration between the Centre Hospitalier Universitaire Vaudois in Switzerland and the Paro College of Education and Royal Thimphu College in Bhutan. Two public urban schools will be randomly assigned to either the "enhanced physical education program" or "standard curriculum" condition. An additional "control school", with no physical education, will be included in the study but not in the randomisation process for feasibility concern. A total of 360 young adolescents (120 per school, aged 12-14) will be enrolled. Baseline data on individual characteristics such as age, gender, and socio-economic status will be collected through self- and parent-reported questionnaires. Primary outcome measures include physical fitness assessed by PE teachers using various metrics, as well as socio-emotional competencies and well-being evaluated through standardised self- and parent-reported questionnaires. Data will be analysed using an intention-to-treat approach. This project offers a unique opportunity to explore the international impact of PE within Bhutan's socio-cultural context.

The Use of Competition in a School-based Intervention for Increasing Cardiorespiratory Fitness in Adolescents

Regular physical activity offers numerous physical, psychological, and cognitive health benefits. However, physical inactivity among adolescents remains a global concern, with 81% of 11- to 17-year-olds failing to meet WHO's recommendation of at least one hour of moderate- to vigorous-intensity activity daily. This inactivity contributes to immediate and long-term health risks, as many non-communicable diseases (NCDs) in adulthood are linked to behaviors established during adolescence. Promoting healthy lifestyles early is crucial for lifelong health and disease prevention. One significant barrier to effective school-based physical activity programs, such as High-Intensity Interval Training (HIIT), is maintaining student motivation. Low engagement often results in poor adherence. Integrating competition-focused on effort rather than performance-may enhance student participation and make HIIT interventions more effective and easier to implement. This study will evaluate the impact of competition on the Burn 2 Learn - Mallorca (B2L-M) program, targeting adolescents aged 15-18. The intervention aims to determine whether competition improves engagement and outcomes compared to non-competitive groups. The primary outcome is cardiorespiratory fitness (CRF), while secondary outcomes include muscular strength, physical activity levels, body composition, mental health (stress and sleep quality), behavior change mediators (self-efficacy, motivation), on-task behavior, blood pressure, and sitting posture. The B2L-M intervention will involve a 16-week, three-arm cluster randomized controlled trial in Mallorca, Spain, recruiting approximately 360 students from six schools. The program includes teacher-led HIIT sessions twice weekly during physical education, supported by information seminars, a dedicated website, and parental e-newsletters. Outcomes will be assessed at baseline and after 16 weeks.
