The purposes of the present study were to explore for the cluster analysis of Dutch Eating Behavior Questionnaire (DEBQ) responses and to examine the effect of eating patterns on counter-regulation. The participants were famale college students(n=144). The results of DEBQ cluster analysis was consistent with Lee(1997); it showed three patterns of eating groups; the Normal Eating Group, the Restrained Eating Group, and the Emotional/External Eating Group. It was a standard counter-regulation experiment. Three kinds of icecream were used for experimental materials. In the preload condition the participants of Emotional/External Eating Group ate more than in nonpreload condition; therefore they showed counter-regulation in preload condition. But in the preload condition the particpants of Restrained Eating Group did not show disreguation in preload condition It suggested that in the high calory preload condition tie Restrained Eating Group regulated eating amount of food better than the Emotional/External Eating Group. The relation of emotional/external eating to counter-regulatory eating was discussed.
