Efficacy of an Attention Guidance VR Intervention for Social Anxiety Disorder

Social anxiety disorder (SAD) is a prevalent mental health concern that impacts approximately 12% of the population. One mechanism thought to maintain SAD is avoidance of faces (i.e. avoidance of negative evaluative threat). However, research on attentional processes in SAD has been confined to paradigms presented on computer monitors. To investigate attentional processes in a more naturalistic way the investigators developed an immersive, 360º-video virtual reality environment using real actors, as part of a pilot study. Participants with a range of social anxiety symptoms (from none to severe) completed a 5-minute speech in this virtual reality environment while their eye movements were recorded. Results from the study showed that greater symptoms of social anxiety were associated with avoidance of looking at faces (i.e. fewer fixations on faces). While existing treatments for SAD are moderately effective, a large number of individuals do not experience meaningful reductions in their symptoms. The overarching goal of this project is inform future treatment research for SAD. The investigators will test a brief attention guidance intervention for SAD that specifically targets avoidance of faces as a potential mechanism maintaining the disorder. The proposed research will use the eye tracking hardware and naturalistic virtual reality environment from the pilot study. The investigators will also collect eye tracking data prior to the intervention in order to investigate potential heterogeneity in the attentional processes of SAD. The investigators will test the hypotheses that (a) the attention guidance intervention, compared to the control intervention, will result in a greater reduction in symptoms of social anxiety, and (b) this effect will be mediated by the number of fixations on faces during a brief public speaking challenge following the intervention. These results will provide causal evidence related to a hypothesized mechanism maintaining SAD.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Attention guidance; In addition to the components included in the control intervention the experimental attention guidance condition consists of three unique components: (1) the rationale will include information about the importance of visually attending to the faces of the audience; (2) in addition to being given a speech topic, participants will be given target audience members to focus their gaze on during the speech. They will be told that they should look at and focus on the target audience member for the whole speech; (3) between speeches, the researcher will tell participants the percentage of time they were focused on the target face.	Behavioral: Attention guidance; Explicitly guiding attention towards faces during public speaking exposures
Active Comparator: Control intervention; Participants will complete two intervention sessions within one week. The intervention will use a manualized protocol.; On the first session, participants will receive a brief standardized psychoeducation module, presented via a 15-minute video recording. This video will explain the intervention, its rationale, and the procedure.; Participants will then have 5 minutes to plan and outline a speech based on a topic given to them. All participants will receive the same topic. Participants will not be allowed to use the outline during the public speaking exposure trials.; Participants will then give six speeches that are each 3 minutes long on the same topic. Participants will give all the speeches in the immersive 360º-video environment.; Between speeches participants will have a 1-minute break.	Behavioral: Control intervention; Public speaking exposures

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Personal Report of Public Speaking Anxiety Scale Post-intervention	Questionnaire that assesses fear of public speaking Score range (total summed score): 34-170; Higher score reflects greater public speaking anxiety	Immediately following the end of the 1-week intervention
Personal Report of Public Speaking Anxiety Scale at 1-week	Questionnaire that assesses fear of public speaking Score range: 34-170 (total summed score); Higher score reflects greater public speaking anxiety	1-week follow-up

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Leibowitz Social Anxiety Scale Post-intervention	Questionnaire that assesses generalized social anxiety Score range (total summed score): 0-144; Higher scores reflect greater social anxiety	Immediately following the end of the 1-week intervention
Leibowitz Social Anxiety Scale at 1-week	Questionnaire that assesses generalized social anxiety Score range (total summed score): 0-144; Higher scores reflect greater social anxiety	1-week follow-up
Speech Anxiety Thoughts Inventory Post-intervention	Assesses cognitions associated with social anxiety Score range (total summed score): 23-115; Higher scores reflect greater severity	Immediately following the end of the 1-week intervention
Speech Anxiety Thoughts Inventory at 1-week	Assesses cognitions associated with social anxiety Score range (total summed score): 23-115; Higher scores reflect greater severity	1-week follow-up
