Anxiety and its treatment: Promoting science-based practice

In this article we analyze ways that psychological science can inform the treatment of anxiety disorders. We focus on experimental psychopathology research to describe the structure of anxiety and the functions of danger, safety, predictability and controllability in contributing to disorder. We then address science-based practice in terms of principles of change and the benefits from the self-corrective nature of science, contrasting this form of practice with treatments that are not grounded in basic learning theory. Models for dissemination and implementation of science-based practices are described and related to practitioner attitudes regarding scientific evidence. Finally, we consider practice implications when treatments are, and are not, based on the informative role of clinical psychological science. (C) 2012 Elsevier Ltd. All rights reserved.
