[Validation of the integration of health belief model and planned behavior theory].

ABSTRACT

OBJECTIVE: To establish and validate a new model of health belief model(HBM) combined with theory of planned behavior(TPB). METHODS: Path analysis was applied to set up a new model predicting iron-fortified soy sauce consumption behavior using baseline survey data among women in rural and urban areas in Beijing, and the model was validated in follow-up survey. RESULTS: It was proved that health values had powerful direct effect on behavior identity and had relatively strong direct effect on attitudes towards behavior; behavior identity had strong effect on behavior barriers, mostly in a direct way, and on behavior intention in a direct or indirect way; control belief was an important external factor influencing behavior intention; behavior intention was the most direct and most important one of factors influencing actual behavior; and convenience to buy was an important external factor influencing actual behavior. CONCLUSION: The integrated model of TPB and HBM explains behavior better and may be attempted in other similar researches.
