Basic Information

• Recruitment Status: COMPLETED

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.

Conditions

Social Anxiety Disorder

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

ABM therapy

The attention bias modification treatment comprises of six computerized sessions, twice a week, in purpose of modulate biases in attention for threat stimuli.

Group Type: EXPERIMENTAL

ABM

Intervention Type: BEHAVIORAL

Participants are trained with a dot-probe task including angry-neutral faces. In 80% of trials the probe appears in place of the neutral face, and in 20% of trials in place of the angry face.
