Repairing one’s mood for the benefit of others: Agreeableness helps motivate low self-esteem people to feel better

The chronic experience and expression of negativity is associated with poorer personal and relationship outcomes. Unfortunately, compared to people with high self-esteem, those with low self-esteem (LSEs) are less motivated to repair their negative moods. The current research examined mood repair in a novel way: in a close relationship context, when mood repair centers on benefitting others. We hypothesized that LSEs are more motivated than usual to repair negative moods when doing so benefits close others and when high in agreeableness (a trait involving prosocial motivation). We found support for our hypothesis with self-report (Studies 1 and 2) and behavioral measures (Study 2) of mood repair motivation, through an experimental manipulation of relationship context (Study 1), when participants expected to communicate with their romantic partners (Study 2), and for both sad (Study 1) and angry (Study 2) moods. Agreeable LSEs were more motivated to repair their negative moods than were disagreeable LSEs.
