An attachment theoretical framework for personality disorders.

Personality disorders are highly prevalent, associated with considerable morbidity, and difficult to treat. Intrapersonal and interpersonal difficulties are central to the pathology observed in personality disorders. Attachment theory provides a broad yet parsimonious explanatory framework for understanding the development, maintenance, and treatment of personality pathology. Attachment theory conceptualizes human behaviour in ways consistent with multiple scientific traditions, including evolutionary, developmental, and neuropsychological domains. The relevant literature has focused predominately on borderline personality disorder, although a few studies have examined attachment associations with other personality disorders, such as narcissistic and avoidant personality disorders. The authors first outline attachment theory and discuss assessment of attachment patterns from both developmental and social psychological viewpoints. Next, the authors present empirical support for attachment theory and its associations with personality, including studies of developmental, physiological, neurobiological, and genetic correlates of personality pathology. They then look at psychotherapy research relevant to (a) underlying components of current psychotherapies, (b) the relation between attachment and both therapy process and treatment outcome, and (c) changes in attachment styles as a result of personality disorder treatment. Finally, the authors call for future research to delve deeper into specific relationships between attachment constructs and personality pathology, as well as to address personality disorders more
