By investigating structural relationships between personal image and self-efficacy, this experimental study purposes to suggest a direction and the meaning of effective education on personal image . Based on scholars` studies on personal image and self-efficacy, this study extracts a revised questionnaire on personal image. The experimental study proved the relationship between the variables of personal image and self-efficacy by using personal image questionnaires which are extracted from the literature study. For this purpose, we have conducted a questionnaire survey including 234 students from women`s university in Seoul. The results of this study are as follows. First, for cognitions on personal image, which are components of the internal image, both the visual image and social image impacting on self-efficacy have a significant efficacy in the self-regulation factor. Second, the satisfaction rates of the components for personal image impacting all the factors of self-efficacy showed a significant effect. Third, the significant results are being obtained from the analysis of differences in self-efficacy according to the levels of satisfaction rates on internal image and social image, which are expected to have effects on the self-efficacybetween the groups for all factors. However, according to the analysis of differences in self-efficacy in relation to the levels of satisfaction for visual images, only the self-confidence factor in the self-efficacy is different between the groups.
