The purpose of the present research is to analyze the visual properties of female college students' self images of body shape quantitatively with the use of line-drawing task and conduct a preliminary examination as to what psychological factor makes a difference between the self image of body shape and real one. In Study 1, 201 subjects' drawings of self body shape were measured in terms of 18 items and analyzed by multi-variate statistics. Eight clusters of the drawings from cluster analyses were well explained by 3 structural variables obtained by a canonical discriminant analysis. In Study 2, 38 subjects' silhouetter photographs were measured, as same as their drawings in Study 1. Then the differences in the structural variable scores between their real body shapes and their self images' were analyzed in a way of taking correlation with their factor scores on the self-esteem inventory in our previous study, indicating a little tendency that those who have a discrepant image of their body thickness from the real were more likely to feel stronger social anxiety.
