When Do Personality and Emotion Predict Destructive Behavior During Relationship Conflict? The Role of Perceived Commitment Asymmetry

The current research examined whether perceived asymmetries in relationship commitment moderate the associations of personality traits and emotional states with enactment of hostile behavior during relationship conflicts. Participants included both members of 53 heterosexual romantic couples (Mage = 25.5 years). Participants completed questionnaire measures assessing personality traits, emotional states, relationship commitment, and perceptions of their partner's commitment. Participants then had an observed conflict discussion with their partner, which was rated by a panel of objective observers for hostile behavior. When participants perceived that they were less committed than their partners, their enactment of hostile behavior was predicted by traits and states that are associated with antisocial and pro‐social orientations (i.e., agreeableness, trait anger, chronic jealousy, and state negative emotion). In contrast, participants who perceived that they were more committed than their partners tended to refrain from hostile behavior, despite traits or states that may suggest hostile inclinations. These results suggest that perceiving that one is less committed than one's partner promotes behavioral expression of interpersonal dispositions and emotions, whereas perceiving that one is more committed than one's partner motivates inhibition of hostile behavior.
