AbstractCognitive psychology has made numerous contributions to clinical psychology, and these contributions are considered especially with reference to the anxiety disorders. It is argued that there are four major contributions that can be identified. First, the cognitive approach has led to the development of complex models showing the main cognitive processes and structures of relevance to an understanding of anxiety disorders. Second, controlled laboratory studies permit a more detailed investigation of cognitive biases in anxious patients than generally is feasible in more naturalistic settings. Third, the cognitive approach provides relevant evidence with respect to the issue of whether cognitive biases play a role in the development and maintenance of anxiety disorders. Fourth, the enhanced understanding of the anxiety disorders that has arisen from the cognitive approach has had beneficial effects on therapeutic practice in a number of significant ways. In sum, it is claimed that clinical psychology has benefited considerably from cognitive theory and research. © 2004 Wiley Periodicals, Inc. J Clin Psychol.
