Attention bias vs. attention control modification for social anxiety disorder: A randomized controlled trial.

Gaze-Contingent Music Reward Therapy (GC-MRT) is an eye-tracking-based attention bias modification protocol for social anxiety disorder (SAD) with established clinical efficacy. However, it remains unclear if improvement following GC-MRT hinges on modification of threat-related attention or on more general enhancement of attention control. Here, 50 patients with SAD were randomly allocated to GC-MRT using either threat faces or shapes. Results indicate comparable reductions in social anxiety and co-morbid depression symptoms in the two conditions. Patients in the shapes condition showed a significant increase in attention control and a reduction in attention to both the trained shapes and threat faces, whereas patients in the faces condition showed a reduction in attention to threat faces only. These findings suggest that enhancement of attention control, independent of valence-specific attention modification, may facilitate reduction in SAD symptoms. Alternative interpretations and clinical implications of the current findings are discussed.
