Interpretation Modification Program for Social Phobia

Social phobia is characterized by severe social anxiety leading to functional impairment
(Schneider et al., 1992). Despite its high prevalence (13%, Kessler et al., 1994) over 30%
of individuals with social anxiety who need treatment do not receive treatment (Olfson, et
al., 2000) and 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 treatments for GSP. Reducing negative interpretation of social
events is an efficacious treatment for SP because:

1. benign interpretations is associated with improvement in social anxiety after treatment
(e.g., Franklin, Huppert, Langner, Leiberg, & Foa, 2005)

2. negative interpretations are implicated in the pathogenesis of SP (e.g., Rapee &
Heimberg, 1997)

3. SPs have more negative interpretations of social events than non-anxious controls and
individuals with other anxiety disorders (e.g., Amir et al, 1998)

4. this bias ameliorates after successful treatment (e.g., Stopa & Clark, 2000).

Therefore, changing negative interpretations is an efficacious treatment for SP, and current
cognitive-behavioral therapies use cognitive restructuring (CR) to target negative
interpretations and replace them with more benign interpretations (Heimberg, et al., 1998).
The goal of the current proposal is to test a new computerized treatment for SP that is
designed to change negative interpretations. We chose a computerized intervention to
increase efficiency and ease of delivery. We chose to test this intervention in GSP because
interpretation bias is especially relevant to this clinical population. The long-term goal
of this project is to improve service delivery using a widely available and economical
intervention for GSP. More specifically, we will test three hypotheses in this proposal:

1. Individuals with GSP completing the Interpretation Modification Program (IMP) will show
a reduction in their negative interpretation

2. Participants in the IMP will show a decrease in their social anxiety symptoms

3. Change in social anxiety symptoms will be mediated by the change in interpretation
scores, suggesting that interpretation change reduced social anxiety symptoms.

Pilot data (n=34) suggest that this intervention is efficacious. Thus, we aim to develop
further and validate this highly efficient treatment for changing interpretations as a
cost-effective treatment for patients with social phobia.
