Agreeableness, extraversion and life satisfaction: Investigating the mediating roles of social inclusion and status.

Abstract

We examine inclusion and status as potential mediators in the relationships between extraversion and agreeableness, on the one hand, and life satisfaction, on the other hand. Previous research has shown that agreeableness is less strongly related to life satisfaction compared to extraversion. We argue that the relatively weak association between agreeableness and life satisfaction is due to the fact that, even though this personality trait is positively related to inclusion, it is only weakly related to status. Using structural equationmodeling (SEM) and survey data from Australia, Denmark and Sweden, we test five hypotheses about the linkages between these personality traits, inclusion, status and life satisfaction. Our results show that both extraversion and agreeableness are positively associated with life satisfaction and that this association is much stronger for extraversion. Furthermore, our results show that extraversion is reliably associated with both inclusion and status, whereas agreeableness is a reliable predictor of inclusion but not of status. Turning to our mediation analysis, our main results demonstrate that the relationship between extraversion and life satisfaction is fully mediated by both inclusion and status, whereas the relationship between agreeableness and life satisfaction is partially mediated by inclusion. Our mediation analysis further shows that agreeableness has a negative direct effect on life satisfaction over and above the positive indirect effect through inclusion. Our findings highlight the role of both inclusion and status as important mediators in the relationships between extraversion and agreeableness, on the one hand, and life satisfaction, on the other hand.
