this study applied the PRECEDE model to investigate dietary predispose , enabling , reinforcing factors and dietary behavior among Chinese-American college students with a community-based nutrition education program and those without the program. A total of 218 students participated in the study. A PRECEDE instrument , including nutritional knowledge , perception of diet and health , dietary instruction , media influence , social support , and dietary behavior , was employed to college pre- and post-test data.
