Default defenses: the character defenses of attachment‑anxiety and attachment‑avoidance

Contemporary attachment researchers claim that attachment-anxiety is associated with a hyperactivating defense strategy while attachment-avoidance is associated with a deactivating defense strategy. However, to date, no study has comprehensively examined the basic patterns of specific defense expression in the two dimensions of attachment insecurity (anxiety/avoidance). To address this research gap, the current study aimed to assess the character defenses associated with attachment-avoidance and attachment-anxiety, incorporating a broad spectrum of psychological defenses. The main objective was to understand what differentiates attachment-avoidance and attachment-anxiety in defensive functioning. In this study of online questionnaire design (N = 250), university undergraduates aged between 17 to 65 completed the Experiences in Close Relationship Scale (ECR) and the Defense Style Questionnaire (DSQ-60). The results show that the two dimensions of insecure attachment exhibit different defensive patterns. Regarding the main findings, attachment-avoidance uniquely predicted defensive isolation, and attachment-anxiety uniquely predicted the defenses splitting, projective identification, anticipation, acting out, passive-aggression, reaction formation, and undoing. Overall, the results indicate that attachment-anxiety is a significant predictor of global defensive functioning, over and above that of attachment-avoidance. One implication of this study is that the two-dimensional model of adult attachment may offer a promising framework for organizing psychological defenses. We discuss the significance of this concerning the future of the empirical study of psychological defenses. The discussion also considers the clinical application and relevance to attachment-based psychotherapy.
