現代青年における自己の多元性とアイデンティティの関連 : 仮面性尺度の作成と青年の類型化

Abstract

This study examined the relationships between multiplicity of self, identity, and psychosocial adjustment in female university students. First, to capture the characteristics of a multifaceted self, we developed a new Masked Self Scale and evaluated its reliability. To further assess its validity and utility, we compared it with scales from previous research. Using the three factor scores of the Self-Plurality Scale(Fujino, 2022) together with the Masked Self Scale score, cluster analysis identified four groups: the Masked Multiplicity Group, the Natural Multiplicity Group, the Unitary Self Group, and the Average Group. One-way ANOVAs were then conducted with cluster membership as the independent variable and MEIS scores and sense of social adjustment as dependent variables. The results showed that the Unitary Self Group and the Natural Multiplicity Group had significantly higher identity and adjustment scores, whereas the Masked Multiplicity Group had significantly lower scores. These findings suggest the existence of an adaptive group with a multifaceted self and offer new insights into identity formation among contemporary youth.
