Sources of self-esteem (SSS) among Japanese university students were investigated and a scale to assess contingency and contentment of SSS was developed. Japanese university students (N=923) participated in a questionnaire survey. In Study 1, which consisted of a free-description survey, 17 sources of self-esteem were identified and arranged into a trilaminar hierarchy. Then, the SSS Scale designed to assesses contingency and contentment was developed. The reliability of the scale was examined using its internal consistency and test-retest correlation. In Study 2, the construct validity of the SSS scale was demonstrated by its correlations with the Big Five Scale, Self-Consciousness Scale, and Time Perspective Scale. Possible applications of the SSS scale in research and clinical practice are discussed.
