The purpose of Project GRAD (Graduate Ready for Activity Daily) was to evaluate a generalizable intervention to promote adoption and maintenance of physical activity among young adults transitioning from university to adult roles. The study, which was conducted from 1993 to 1997, improved on previous research by assessing longer-term outcomes of both physical activity and theoretically derived mediators, and the relation between the two. The survey assessed physical activity and numerous theory-based psychosocial and environmental mediators.
