大学生における関係的自己の可変性と精神的健康および自我同一性との関連

The purpose of this paper was to investigate the relationship among the variability in the relational-self, identity, and mental health in university students. The variability in the relational-self consists of three aspects (Sakuma & Muto, 2003): The motives toward the self-concept depending on social relations, the sense of incongruity for variability in that aspect of self-concept, and the degree of their perceived variability. 315 participants completed questionnaires about the variability in the relational-self, the multidimensional ego identity scale (MEIS) and aspects of mental health. The main results were as follows. (1) The participants were divided into three groups in accordance with their scores. (2) Both men and women in the conflicting variability group had an adverse mental health and lower identity scores than others. (3) Men in the low variability group and women in the unintentional variability group had a good mental health and high identity score. (4) Women in the high variability group had negative emotion and high identity score. These results suggest that it is necessary to consider support for each group.
