Moral identity is associated with people's subjective well-being; however, little is known about how an individual with moral identity relates to one's subjective well-being. Based on the eudaimonic identity theory, the current study proposed that identity commitment quality is a critical mechanism that links moral identity (two dimensions: internalization and symbolization) and subjective well-being. We examined our hypotheses in 419 college students, who completed the Self-importance of Moral Identity Questionnaire, Satisfaction with Life Scale, Scale of Positive and Negative Experience, and Questionnaire for Eudaimonic Well-being. Results confirmed significant positive correlations among moral identity, identity commitment quality, and subjective well-being; findings also suggested that both the internalization and symbolization dimensions of moral identity predicted subjective well-being through identity commitment quality, and identity commitment quality fully mediated the pathway relationship between moral identity and subjective well-being. We discussed these findings with respect to implications and proposed research suggestions for future studies.
