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


CONCLUSIONS
The integrated model of TPB and HBM explains behavior better and may be attempted in other similar researches.
