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.
KeywordsAgreeableness; Neuroticism; Somatic Symptoms; Self-Regulation; Effortful Control Agreeableness is often viewed in terms of its interpersonal correlates. Experience-sampling studies have found that, in comparison to disagreeable individuals, agreeable individuals generally engage in less quarrelsome behavior and more cooperative behavior in daily life (Moskowitz, 1994). In terms of the social cognitive basis of agreeableness, this trait dimension has been associated with less perceived interpersonal conflict in laboratory interaction paradigms (Graziano, Jensen-Campbell, & Hair, 1996) and agreeable individuals exhibit a preference for more socially adaptive modes of conflict resolution (Graziano et al., 1996;Jensen-Campbell & Graziano, 2001).In addition, we suggest that agreeableness may also tap broad tendencies toward effortful control in domains that are less tied to interpersonal outcomes. Consistent with this perspective, Tangney, Baumeister, and Boone (2004) report a relationship between agreeableness and a dispositional self-control measure assessing the ability to override intrapsychic urges, such as those related to overeating or laziness. Furthermore, Jensen-Campbell et al. (2002) found that agreeableness was associated with smaller Stroop-interference effects, suggesting superior abilities to inhibit cognitive conflicts.
