An Analysis of Self-Discrepancy Scales: Focusing on Measures Used in Korean Research

This study aimed to analyze the scales used in domestic research to measure the concept of self-discrepancy and to examine their structural and methodological characteristics. To this end, 25 relevant scales were collected and analyzed. The results were categorized into modified versions of the Selves Questionnaire developed by Higgins et al. (1985), independently developed scales, and scales related to similar constructs. The analysis revealed that various modified versions of Higgins’ Selves Questionnaire are actively used in Korea; however, repeated modifications of the original scale may risk distorting its intended purpose. Furthermore, the scales varied in terms of response formats, scoring methods, and the types of self-states included, which may limit comparability across studies. Particularly in collectivist cultures like Korea, the boundary between the ideal self and the ought self can be ambiguous, underscoring the need for developing culturally sensitive scales. This study offers implications for the future theoretical refinement and culturally appropriate development of self-discrepancy measures.
