Romantic jealousy and adult romantic attachment.

Research on romantic jealousy is consistent with the idea that jealousy is, at least in part, the product of threats to attachment relationships. Attachment theory was used as a framework for examining individual differences in the ways in which people experience and express jealousy. Emotional, behavioral, and cognitive concomitants of romantic jealousy were related to differences in attachment style in ways consistent with attachment theory. For example, anxious participants were relatively more likely than others to resist expressing their anger, avoidant participants were especially likely to turn their anger and blame against the interloper, and securely attached participants were especially likely to express anger toward the partner and to maintain their relationship. Differences in attachment style, not just differences in level of security, are predictive of qualitative individual differences in jealousy experiences.
