Physical activity declines during adolescence. The Theory of Planned Behaviour (TPB) is a useful framework for investigating activity but leaves variance unexplained. We explored the utility of a dual-process approach using the TPB and the Prototype Willingness Model (PWM) to investigate correlates of physical activity, and 1-year change in physical activity, among a large sample of adolescents.

原型相似性对身体活动的重要性：青少年大样本中的横截面和纵向关联


青春期期间体力活动减少。计划行为理论 (TPB) 是研究活动的有用框架，但无法解释差异。我们探索了使用 TPB 和原型意愿模型 (PWM) 的双过程方法的实用性，以调查大量青少年样本中身体活动的相关性以及身体活动的一年变化。
