Personality traits and anxiety symptoms: the multilevel trait predictor model.
Investigation of relations between personality traits and mental disorders can inform key issues in psychopathology research. However, it has been hindered by extensive correlations among the traits. Building on studies of affect-psychopathology relations (e.g., the tripartite model), an organizational framework is proposed to solve this problem with respect to anxiety pathology. To test the resulting model, associations between four traits (negative emotionality, positive emotionality, anxiety sensitivity, and negative evaluation sensitivity) and four anxiety symptoms (chronic worry, obsessive-compulsive symptoms, panic, and social anxiety) were examined in an undergraduate sample (N=907). Confirmatory factor analyses supported operationalizations of the constructs in this study. Examination of the trait-symptom links using hierarchical multiple regression analyses supported most of the predicted relations. Specifically, negative emotionality emerged as a general predictor that was significantly related to all four symptom dimensions. In contrast, anxiety sensitivity was specific to panic and worry, whereas negative evaluation sensitivity was specific to social anxiety and worry. Finally, positive emotionality was uniquely related to social anxiety. The model accounted for a substantial amount of variance in the symptoms and almost all of the covariation among them.
