Long-term Impact of PE Teacher Interventions on Adolescent Leisure Time Activity and Motivation

This project aims to develop a three-month face-to-face and web-based intervention program for physical education (PE) teachers to increase autonomy, competence, and relatedness supportive behaviour toward their students and to avoid the respective need-thwarting behaviours toward their students. The effectiveness of the intervention program is examined at multiple time points during the three-month period. After the intervention program, it is expected that the experimental group students demonstrate significantly higher intrinsic motivation toward physical activity (PA) and are significantly more physically active, as measured by accelerometers, compared to control group students. Additionally, unique effects of autonomy, competence, and relatedness support interventions on students' intrinsic motivation and PA will be investigated. This project provides highly valuable input for PE teacher training to increase students' intrinsic motivation and their overall PA.
