The purpose of this study was to develop a questionnaire to measure determinants of the theory of planned behavior (TPB), verify the model compatibility of the TPB, and to predict influencing factors on the intention of healthy eating‐out. Data were collected from 765 free living residents in Seoul aged 19 and above. Face‐to‐face interviews were carried out in order to measure beliefs in the TPB variables. Validation of questionnaire was assessed by factor analysis and Cronbach’s alpha. Regression analyses were used to verify the model compatibility of the TPB and analyze influencing factors on the intention. Factor analysis with varimax rotation revealed 6 factors as which were designed. Cronbach’s alpha coefficients were from .73 to .95 for the determinants. The TPB model was verified to be applicable for measuring intention (p<.0001). Attitudes were the most influencing factors to the intention of those who prefer Korean meal for eating‐out (β=0.02509 p<.0001), Chinese (β=0.05567,p=.0001) and Western dishes (β=0.0493,p<.0001). Perceived behavioral controls were the most influencing factors to the intention of those who prefer Japanese dish (β=0.02617,p=0.0067) or fast food (β=0.04882,p=0.0001). The study results indicated that the TPB was useful to measure the intention of healthy eating‐out among urban Koreans. (This work was supported by the Brain Korea 21 Project in 2007.)
