This study was to apply augmented model of Ajzen's(1991) theory of planned behavior and Prototype/Willingness model to healthy and unhealthy eating behaviors and test the validities. For this purpose, the predictive powers of the precedents of each models were investigated at the sample of 183 females of University in Seoul using Structural Equation Modeling. The main results were as follows. First, the fitness of each theoretical models were moderately satisfactory, however those of P/W model were slightly better. Path coefficients showed that the predictive power of intention was stronger than willingness and two theoretical models were supported more in eating monitoring behavior than eating disorder behavior. In the case of eating monitoring behavior, attitude and perceived behavioral control predicted intention which was the only predictor influencing behavior. Also, prototype and prevalence predicted willingness which had direct and indirect effect on behavior through the effect of intention. In the case of eating disorder behavior, only attitude predicted intention and perceived behavioral control and intention predicted behavior. Also, prototype predicted willingness and intention. In addition, willingness had only indirect effect on behavior through the effect of intention. Finally, the limitations of this study and the implications for future studies were discussed.
