Abstract: Patterns of comorbidity among common mental disorders can be understood from the perspective of a model that regards mood, anxiety and somatization disorders as elements within an internalizing spectrum of disorder, and substance use and antisocial behavior disorders as elements within a separate externalizing spectrum of disorder. In this chapter, we evaluate the possibility of linking this model to literature on chronic pain. Evidence from psychosocial and biological perspectives points towards mechanisms that link chronic pain to internalizing disorders. Such evidence indicates that the internalizing-externalizing model may provide a useful framework for suggesting new directions for research on connections between chronic pain and mood, anxiety, and related disorders and traits.

Abstract: Recent progress toward the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders includes a proposed quantitative hierarchical structure of internalizing pathology with substantial, supportive evidence (D. Watson, 2005). Questions about such a taxonomic shift remain, however, particularly regarding how best to account for and use existing diagnostic categories and models of personality structure. In this study, the authors use a large sample of psychiatric patients with internalizing diagnoses (N = 1,319) as well as a community sample (N = 856) to answer some of these questions. Specifically, the authors investigate how the diagnoses of obsessive-compulsive disorder (OCD) and bipolar disorder compare with the other internalizing categories at successive levels of the personality hierarchy. Results suggest unique profiles for bipolar disorder and OCD and highlight the important contribution of a 5-factor model of personality in conceptualizing internalizing pathology. Implications for personality-psychopathology models and research on personality structure are discussed.

Abstract: There are systematic and meaningful links among normal and abnormal personality traits and Axis I and II constructs from the DSM. Nevertheless, much research in this area focuses on pairs of constructs (e.g., the link between personality traits and a specific Axis I disorder), rather than on the broader multivariate structure of the personality-psychopathology domain. We underscore the need for this broader perspective, a perspective that would transcend largely artificial boundaries between current constructs (e.g., normal and abnormal personality). We outline our approach to research from this perspective and we emphasize the internalizing (mood and anxiety) and externalizing (substance use and antisocial behavior) spectra as promising foci for initial research on the joint structure of personality and psychopathology.
