These findings highlight the role of openness in emerging adults’ romantic relationships from a dyadic angle.
Meanwhile, although previous studies on the relationship between personality and relationship quality have used both individual samples and dyadic samples among marriage cohorts (Holland and Roisman, 2008; Dyrenforth et al., 2010; Mund and Neyer, 2014), the changing life stages, demands, and expectations outside the intimate relationship may lead to different effects on personality (Shiota and Levenson, 2007), so it is necessary to dedicate the research on the effect of personality on emerging adults’ romantic relationships. Dissertations that have an embargo placed on them will not be available to anyone until the embargo expires.Past work has linked psychological trauma to problems in romantic relationships and to the quality of social attachment in clinical populations and adult married couples.This study tested emerging adult couples’ openness and its fit effect on their romantic relationship quality using quadratic polynomial regression and response surface analysis. Both dyads’ openness and relationship quality were measured. The result showed that (1) female and male openness contribute differently to relationship quality; (2) couples with similar high openness could experience better relationship quality than those with similar low openness traits; and (3) when dyadic openness is dissimilar, it is better to be either relatively high or relatively low than to be moderate. doi: 10.1002/ab.20277 Pub Med Abstract | Cross Ref Full Text | Google Scholar Holland, A.
