Augmentation Study of A Computerized Treatment for Social Anxiety Disorder

Summary

The purpose of this study is to determine whether briefly reactivating a fear memory 10 minutes prior to administering a social anxiety treatment will enhance the durability of treatment effects.

Conditions

• Social Anxiety Disorder

Interventions

BEHAVIORAL

CBM With Active Fear Reactivation

Participants will undergo a fear reactivation trial, which involves giving a one-minute impromptu speech after only 30 seconds of preparation time. 10 minutes afterwards, they will be given CBM for interpretation bias. Training will involve 84 social scenario vignettes, with 70 resolving positively, 7 resolving negatively, and 7 resolving neutrally. This training takes places during the "memory reconsolidation window" that opens after fear reactivation, during which time the fear memory is in a labile state and thus more amenable to rewriting.

BEHAVIORAL

CBM With Inert Fear Reactivation

Participants will undergo a fear reactivation trial, which involves giving a one-minute impromptu speech after only 30 seconds of preparation time. 12 to 36 hours afterwards, they will be given CBM for interpretation bias. Training will involve 84 social scenario vignettes, with 70 resolving positively, 7 resolving negatively, and 7 resolving neutrally. Because this training takes places well outside of the "memory reconsolidation window" that opens shortly after fear reactivation, the reactivation is not expected to have any effect, and only serves as a control.

BEHAVIORAL

Inert CBM With Inert Fear Reactivation

Participants will undergo a fear reactivation trial, which involves giving a one-minute impromptu speech after only 30 seconds of preparation time. 12 to 36 hours afterwards, they will be given an inert form of CBM, which should not influence the direction of interpretation bias. Training will involve 84 social scenario vignettes, with 70 resolving neutrally, 7 resolving positively, and 7 resolving negatively. Because the CBM training takes places well outside of the "memory reconsolidation window" that opens after fear reactivation, the reactivation is not expected to have any effect, and the inert CBM training is not expected to have any effect either. This condition only serves as a control for the other two conditions.
