Abstract
This introductory chapter presents a focused survey of the literature on the interaction between depression and personality, which represents one of the approaches to the issue of complex depression, which is treated from different perspectives throughout this book. Patients who, in addition to a depression, present with personality dysfunction are more than twice as likely to be nonresponders to treatment compared to patients with common, stand-alone depression. Furthermore, personality styles and the level of structural integration of personality are, as well, related to severity and to the response to treatment. For this reason, in order to assess complex depression and to improve treatment, it is important to deepen our understanding of the interaction of depression and personality. We examine this issue from the perspective of functional domains that are differentially affected in depression concurrent with personality dysfunction and specific personality styles, as well as how the co-occurrence of both impacts on the severity of the condition. The chapter outlines the complex and multimodal relationships between depression and personality dysfunction, discussing specific models for the interaction between depression and borderline personality disorder, on one hand, and personality styles and structural personality integration, on the other hand.
