Description

We created a simple questionnaire to promote better eating habits and behavioral modification for the prevention and improvement of metabolic syndrome, examined its reliability and validity, and finally, assessed its effectiveness. A questionnaire, comprising of eighteen items to promote behavioral modification, was prepared comprising of three factors, “dietary recognition” , “eating habits” and “eating action” and was developed based on data from 125 students at the Faculty of Dentistry, The University of Tokushima. Furthermore, to assess the effectiveness of this version of the questionnaire, we conducted a survey on 845 health-care providers in Tokushima Prefecture and Hyogo Prefecture. The results confirmed a relatively high internal consistency with a Cronbach's alpha coefficient of 0.735–0.762 for the three factors. The questionnaire scores in the “obese” group with a body mass index of 25 or higher were high for all three factors and a significant difference was noted between the “normal” and “thin” groups under the category of “dietary awareness” . Moreover, trends between men and women; and between age groups were ascertained, therefore suggesting that this questionnaire is effective in assessing eating behavior associated with obesity.
