Abstract

Depression is among the most prevalent and disabling mental health conditions worldwide, and its developmental and interpersonal determinants remain incompletely understood. Drawing on Bowlby's attachment theory, this review examines the differential associations of attachment anxiety and attachment avoidance with depression, the cognitive and regulatory mechanisms that may underlie these associations, and their implications for clinical practice. Evidence from meta-analytic and longitudinal research indicates that both dimensions are associated with elevated depression risk, with attachment anxiety showing stronger and more direct associations operating through hyperactivating emotion regulation and ruminative cognitive processing, whereas attachment avoidance tends to operate through more indirect pathways, including expressive suppression and impaired social support utilization. Rumination represents a dimension-specific mechanism more reliably implicated in the anxiety–depression pathway, with suppression-based emotion regulation representing a more salient pathway for avoidance-related depression. At the clinical level, attachment dimensions shape therapeutic alliance formation, may moderate differential treatment response, and may serve as meaningful intervention targets, though the evidence base remains limited by cross-sectional designs, measurement heterogeneity, and a predominance of Western samples. Future research would benefit from longitudinal designs, greater use of dimensional attachment assessment, and clinical trials evaluating attachment-informed interventions across diverse populations. This review affirms the value of treating attachment anxiety and avoidance as distinct rather than interchangeable dimensions, offering a developmentally grounded framework for understanding depressive vulnerability and informing more precise clinical approaches.
