Abstract
The purposes of this study were to develop a separated-identity scale (SIS) and a related-identity scale (RIS), and to examine the concepts of the separated-identity and the related-identity in adolescents. Study I (Items were chosen based on the definition of separated identity) was completed by 290 university students. Factor analysis yielded 3 factors. The 12-item SIS was completed by 232 university students. Reliability and validity of the SIS were confirmed. Study II (Items were chosen based on the definition of related identity) was completed by 270 university students. Factor analysis yielded 7 factors. The 24-item RIS was completed by 192 university students. Reliability and construct validity of all the RIS were confirmed. But there is enough reason to reexamine the reliability and validity of certain factors. The results showed as follows: (1) The separated-identity of males was superior to females and the related-identity of females was superior to that of males. (2) The separated-identity had a negative relationship with "Neuroticism", while the related-identity had a positive relationship to "Extraversion", "Conscientiousness" and "Agreeableness".
