Development of the Japanese version of the Revised Unmitigated Communion Scale

Abstract

The purpose of this study was to develop the Japanese version of the Revised Unmitigated Communion Scale (J-RUCS) and examine its reliability and validity. Participants included 423 Japanese university students. The confirmatory factor analysis indicated that J-RUCS had two error covariances; however, it did not indicate a unidimensional structure. As for reliability, adequate internal consistency and test-retest reliability were confirmed. Regarding validity, there were positive associations between J-RUCS and affiliation, empathic concern, negative communion, self-devaluative view adjectives, preoccupied attachment style, agreeableness, and neuroticism. Additionally, J-RUCS scores were negatively correlated with self-assertion and self-esteem. These results, which are consistent with previous studies, showed the validity of the J-RUCS.
