Abstract
The purpose of the present research is to explore the effects of the relationship among relational mobility, cultural self-construal, and group-representation (common identity group-representation and common bond group-representation) on self-effacement toward in-group members. The Japanese interpersonal communication competence was added in this investigation as a mediating variable. A path analysis based on the structural equation modeling was conducted. Among particularly notable results, relational mobility had a negative effect on common bond group-representation via interdependent-self and had a direct positive path on common bond group-representation; it also directly had a negative path on self-effacement. Additionally, having a common bond group-representation inhibited the expression of self-effacement, contrastively facilitated self-restraint, and had a positive effect on self-effacement.
