Abstract
Depression is often complicated by concurrent personality dysfunction, which poses significant challenges for clinicians and researchers. Complicated depression is thus broadly presented as a useful clinical and scientific entity, describing clients presenting with depressive symptoms that are further complicated by personality dysfunction or personality pathology. The article introduces a collection of research‐based papers addressing the clinical management of patients with complicated depression. The articles in the issue provide an up‐to‐date framework for understanding different forms of complicated depression and provide useful clinical information to illuminate the treatment of clients presenting with difficulties at the intersection of depression and personality dysfunction.
