A cognitive model of generalized anxiety disorder (GAD) is described. The model asserts that generalized anxiety is an abnormal worry state. In this model, GAD results from the usage of worrying as a coping strategy and subsequent negative evaluation of worrying. The use of worry as a strategy is supported by positive metabeliefs concerning worry, whereas the negative appraisal of worrying (worry about worry) is linked to negative metabeliefs developed out of previous experience. These beliefs center on the themes of uncontrollability of worries and the dangerous consequences of worrying. Negative appraisal of worrying is associated with behavioral and cognitive responses that serve to maintain unwanted thoughts, and preserve dysfunctional beliefs. A review of the literature indicates that the model is consistent with existing data. Predictions and treatment implications of the model are discussed.
