Although there is ample evidence linking insecure attachment styles and intimate partner violence (IPV), little is known about the psychological processes underlying this association, especially from the victim’s perspective. The present study examined how attachment styles relate to the experience of sexual and psychological abuse, directly or indirectly through destructive conflict resolution strategies, both self-reported and attributed to their opposite-sex romantic partner. In an online survey, 216 Spanish undergraduates completed measures of adult attachment style, engagement and withdrawal conflict resolution styles shown by self and partner, and victimization by an intimate partner in the form of sexual coercion and psychological abuse. As predicted, anxious and avoidant attachment styles were directly related to both forms of victimization. Also, an indirect path from anxious attachment to IPV victimization was detected via destructive conflict resolution strategies. Specifically, anxiously attached participants reported a higher use of conflict engagement by themselves and by their partners. In addition, engagement reported by the self and perceived in the partner was linked to an increased probability of experiencing sexual coercion and psychological abuse. Avoidant attachment was linked to higher withdrawal in conflict situations, but the paths from withdrawal to perceived partner engagement, sexual coercion, and psychological abuse were non-significant. No gender differences in the associations were found. The discussion highlights the role of anxious attachment in understanding escalating patterns of destructive conflict resolution strategies, which may increase the vulnerability to IPV victimization.
