Validation of the integration of health belief model and planned behavior theory / 北京大学学报(医学版)

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 beha-vior.Conclusion:The integrated model of TPB and HBM explains behavior better and may be attempted in other similar researches.
