This study examined the relationship between self-concept variability and psychological well-being. We hypothesized that the meaning of interpersonal relationships moderated the effect of self-concept variability on psychological well-being.

The results showed that subjective self-concept variability was positively correlated with psychological well-being, although self-concept differentiation was not correlated with psychological well-being.

The results suggest that the meaning of interpersonal relationships is an important determinant of the integration of self.
