The purpose of this study was to translate a measure of self-understanding of interpersonal patterns(SUIP) into Korean and to evaluate the reliability and validity of the SUIP, which Connolly et al(1999) developed. For this purpose, the measure was translated and then administered to a client sample and a student sample. The SUIP consisted of self-understanding score and recognition score. Internal consistency was .62, .67 for recognition score, and .63, .68 for self-understanding score. Test-retest reliability was .62 for recognition score and .47 for self-understanding score. The measure demonstrated discriminant validity with SQ-90-R, Korean Inventory of Interpersonal Problems(KIIP-C), Self-concept inventory. And the self-understanding score of SUIP also demonstrated convergent validity with reflectiveness scale and openness to feelings and ideas scale. In addition the theoretical implications and practical use of the SUIP is discussed.
