Agreeableness and the Self-Regulation of Negative Affect: Findings Involving the Neuroticism/Somatic Distress Relationship.

In the temperament literature, agreeableness has been theoretically linked to effortful control. Further, research in this area has suggested that effortful control may play a broad role in moderating temperament-based tendencies toward negative affect. The present three studies, involving a total of 300 undergraduate participants, sought to extend this perspective to the adult literature by examining potential interactions between agreeableness and neuroticism in predicting reported somatic symptoms. Although such symptoms have been linked to neuroticism, they are not characteristic of the interpersonal concerns linked to agreeableness. Nevertheless, all studies found that agreeableness and neuroticism interacted to predict somatic symptoms such that high levels of agreeableness decoupled the relationship between neuroticism and somatic distress. These findings indicate a broad role for agreeableness in the self-regulation of neuroticism-linked distress.
