The purpose of this study was to clarify feelings of self-disgust and developmental changes during adolescence. Five hundred and seventy-one adolescents described their feelings of self-disgust, and from their responses, one hundred and fourteen items questionnaire were constructed. One thousand and six hundred eighty-two adolescents, including junior, senior high school students, and university students completed this questionnaire. From the results of the factor analysis, eight factors were identified as elements of feeling of self-disgust. INDSCAL was conducted using seven variables out of eight factors and one variable which is the main constituent of self-disgust, from another factor analysis. As a result, three dimensions were found. It is suggested that feelings of self-disgust during adolescence change from the state of escape from self-recognition to self-confrontation, from the state of self-recognition in imagination to reality, as they grow older.
