Generalized Social Phobia (GSP) is characterized by severe social anxiety that leads to functional impairment (Schneider, et al., 1992). The prevalence of GSP is 13.3% (lifetime, Kessler, et al., 1994), ranking third among all psychiatric disorders. Despite its high prevalence, over 30% of individuals with social anxiety who need treatment do not receive treatment for a variety of reasons (e.g., afraid of what others might think, Olfson, et al., 2000). Additionally, 40% of individuals who present for treatment do not respond (39% Heimberg, et al., 1998; 42%, Liebowitz et al., 2005). Thus, there is a clear need to develop highly effective and efficient treatment procedures for social phobia. This three-year proposal aims to test a computerized treatment for social anxiety in a double-blind, placebo-controlled study. Specifically, research suggests that individuals with social phobia direct their attention toward socially-relevant negative information. Therefore, the treatment will focus on changing this attention bias and thereby alleviate symptoms of social anxiety. We present the results of a pilot study (n=26) in treatment seeking socially phobic individuals demonstrating the effectiveness of the treatment. A larger study would allow us to test the treatment and perhaps modify its component to increase its efficacy. The preliminary results of the pilot are encouraging. In brief, our intervention was effective in: a) changing biased attention in socially anxious individuals, b) generalizing this change in disengagement of attention from threat to other measures of attention disengagement, c) reduce symptoms of social anxiety as assessed by an independent rater, d) maintain a high rate of compliance (0% drop out in the pilot study), and e) maintain its effects in follow-up assessment up to one year. This efficient and efficacious techniques for changing attention bias in social phobia can provide a cost-effective and easy to administer treatment that is grounded in basic cognitive science and may help reduce suffering in individuals with GSP. We will test two hypotheses in this proposal. 1) Individuals with GSP completing the Attention Disengagement Training (ADT) will show a larger reduction in their symptoms compared to the placebo group on an interviewer measure of social anxiety (Liebowitz Social Anxiety Scale, LSAS). 2) Individuals with GSP completing ADT will show a larger reduction in their self-report of social anxiety symptoms compared to the placebo group
