Process Evaluation of a School‐Based Intervention Promoting Sleep Health in Adolescents
BACKGROUND: Poor sleep health is increasingly recognized as a public health issue. Despite the potential of school-based interventions, few have successfully improved adolescent sleep health. To enhance intervention effectiveness, feasibility, and relevance, it is essential to understand barriers and facilitators affecting the adoption, implementation, and sustainment. This study evaluates these aspects for the sleep health promoting school-based…
Charge Your Brainzzz
Inadequate sleep among Dutch adolescents is a complex public health issue with detrimental effects on physical and mental well-being. Previous interventions have shown limited or no lasting effects. While systems approaches help to understand and address such challenges, effective prevention efforts require theory- and evidence-based intervention design using behavior change techniques. This study outlines the systematic development of a ‘whole s…

Agreement between parent and child report on parental practices regarding dietary, physical activity and sedentary behaviours
Parents and children perceive parental practices regarding dietary, physical activity and sedentary behaviours differently in all parts of Europe, with considerable variation across specific practices and countries. Therefore, future studies should assess both, parents and children's view on parental practices
Predicting fruit consumption
Both habit and previous behavior are important as predictors of future behavior, and as educational objectives for behavior change programs. Our results revealed less stability for the constructs over time than expected. Habit strength was to a large extent mediated by previous behavior and our results do not strongly suggest a need for the inclusion of both constructs. Future research needs to assess the conditions that determine direct influenc…

Exploring mediators of accelerometer assessed physical activity in young adolescents in the HEalth In Adolescents study – a group randomized controlled trial
While no mediation effects were observed, change in both personal and social-environmental factors predicted change in physical activity behavior. Hence, a social- ecological approach targeting a wide range of determinants to promote change in physical activity holds promise. Overweight and normal weight adolescents may not respond in the same way to school-based physical activity interventions. Therefore, strategies to better reach the overweigh…
