Differentiation of Self Predicts Life Satisfaction through Marital Adjustment

Abstract

Previous studies have documented the link between differentiation of self and life satisfaction. However, the underlying mechanisms explaining these associations are yet to be tested at the dyadic level. This study examined the mediating role of marital adjustment in the association between differentiation of self and life satisfaction among 113 Turkish heterosexual married couples (N = 226). Analyses using the Common Fate Model demonstrated that differentiation of self was associated with higher levels of marital adjustment and life satisfaction, such that marital adjustment was positively associated with life satisfaction, and in turn, marital adjustment fully mediated this association. Implications are discussed for clinicians and cross-cultural researchers who seek to promote greater life satisfaction by targeting both differentiation and marital adjustment.
