Depression and Emotion Regulation: A Synthesis of Contemporary Models and Treatment Pathways

Depression remains one of the most pervasive mental health conditions globally, and contemporary research increasingly positions emotion regulation (ER) as a central mechanism underlying its onset, maintenance, and recurrence. This review synthesizes current theoretical models and empirical findings to clarify how maladaptive ER processes—such as rumination, suppression, and experiential avoidance—interact with cognitive, neural, and interpersonal factors to shape depressive symptomatology. Evidence from affective neuroscience highlights disruptions in fronto-limbic circuitry that impair the ability to modulate negative affect, while cognitive-behavioral models emphasize biased information processing and heightened self-referential thinking. Integrative frameworks, including the Process Model of Emotion Regulation and the Extended Cognitive Model of Depression, illustrate how these mechanisms converge to exacerbate mood dysregulation. The review also evaluates contemporary treatment pathways that target ER deficits, including cognitive-behavioral therapy, mindfulness-based interventions, dialectical behavior therapy, and emerging approaches such as emotion-focused therapy and neurofeedback. Findings indicate that interventions which improve adaptive ER skills—such as cognitive reappraisal, acceptance, and problem-solving—are associated with meaningful reductions in depressive symptoms and enhanced resilience. Despite significant advancements, gaps remain regarding individual variability in ER profiles, cross-cultural considerations, and long-term treatment effects. The review concludes by outlining implications for personalized treatment planning and proposing future research directions focused on integrating biological, psychological, and contextual determinants of emotion regulation in depression.
