Web-based need-supportive parenting program to promote physical activity in secondary school students: a randomized controlled pilot trial.

Background: Current global trend of insufficient physical activity (PA) among children and adolescents highlights the necessity of finding effective ways to promote PA in childhood. Self-determination theory (SDT) has demonstrated efficacy as a conceptual framework for developing interventions aimed at promoting diverse health behaviours. Parents have potential to influence children's health behaviours to a great extent, which could be enhanced from an online, self-paced training to gain knowledge on how to support children's intrinsic motivation towards particular health behaviour.

Fostering Need-Supportive Behaviors in Physical Education Teachers and Parents: A Cluster Randomized Controlled Trial Study Protocol of a Web-Based Intervention on Secondary School Students' Physical Activity.

Despite various benefits of physical activity, children are increasingly inactive. Both school physical education classes and support from parents are important determinants of physical activity level of children and adolescents. We aim to develop a web-based intervention for physical education teachers and parents to teach them to be more need-supportive towards children when discussing physical activity and thus increase children's autonomous motivation towards it.
