Abstract:
The current study examined actor, partner, and similarity effects of personality on a variety of well-being indices, including both global and experiential measures of well-being in 2,578 heterosexual couples (N = 5,156 individuals; M = 51.04, SD = 13.68) who completed the 2016 Wellbeing and Daily Life supplement to the Panel Study of Income Dynamics (PSID). Among actor effects, those for conscientiousness, agreeableness, extraversion, and neuroticism were the most robust predictors of well-being. Among partner effects, conscientiousness and neuroticism were the most robust predictors of well-being. Consistent with past research, similarity effects on well-being were generally small and not always significant. The results are discussed in the context of experiential conceptualizations of well-being and operationalizing similarity in relationship research.
