Which educational method did Sallis et al. utilize in their 1999 study?

Sallis et al. utilized a Classroom-Based Health Education Program in their 1999 study as a structured approach to promote physical activity and enhance health knowledge among participants. This method typically involves organized instructional sessions that deliver health content effectively within a learning environment, allowing for interaction and engagement among students. Classroom settings facilitate the presentation of educational materials, group activities, and direct communication, which can significantly impact participants' understanding and attitudes toward exercise and health.

This approach was particularly effective as it allowed for a controlled environment where students could learn together, reinforcing social norms around physical activity and encouraging motivational support amongst peers. Such classroom-based programs are widely recognized for their ability to influence behavior change through comprehensive and systematic education on health-related topics.
