Study Overview
Brief Summary
This study examines whether the ability to extract statistical properties from the environment among treatment-seeking patients with social anxiety disorder can predict therapeutic response to attention bias modification (ABM), namely, reduction in symptoms of social anxiety following ABM therapy.
Detailed Description
All participants received 6 sessions of ABM therapy away from threat. At baseline participants also completed a gold standard statistical learning task aimed to assess participants' capacity for the extraction of statistical regularity from the environment. The aim of the study is to determine whether the basic ability to extract rules from the environment at baseline could predict clinical improvement of social anxiety symptoms.

Outcomes
Primary Outcomes
The Liebowitz Social Anxiety Scale (LSAS) - Diagnostic Interview scores
Time Frame: 1-2 weeks after treatment completion
The Liebowitz Social Anxiety Scale is a clinician-rated inventory consisting of 24 items describing socially relevant situations. Each situation is rated in relation to the past week on two sub-scales ranging 0-3: level of fear and level of avoidance experienced in response to these situations. Item scores are summed to a total score ranging 0-144
Secondary Outcomes
- The Social Phobia Inventory scores(1-2 weeks after treatment completion)
