Individuals high in attachment anxiety often experience persistent negative self-perceptions and heightened sensitivity toward perceived relationship threats. These characteristics may extend into past romantic relationships. This study examined whether individual differences in attachment style predict self-evaluations and relationship social comparison frequency. Two hundred and fifty-nine individuals rated themselves, their partner, and their current partner's ex-partner (CPE) or their ex-partner's current partner (ECP) on several dimensions. Individuals high in attachment anxiety experienced more relationship uncertainty but were not less satisfied than individuals low in attachment anxiety. They also made more comparisons in general and to relationships involving an ex-partner, and viewed themselves less positively than they viewed their CPE/ECP. Findings are discussed with respect to the influence that past relationships might hold over anxiously attached individuals’ current relationships.
