ABSTRACT
There is some evidence for heterogeneity in attentional processes among individuals with social anxiety. However, there is limited work considering how attentional processes may differ as a mechanism in a naturalistic task-based context (e.g., public speaking). In this secondary analysis we tested attentional heterogeneity among individuals diagnosed with social anxiety disorder (N = 21) in the context of a virtual reality exposure treatment study. Participants completed a public speaking challenge in an immersive 360°-video virtual reality environment with eye tracking at pre-treatment, post-treatment, and at 1-week follow-up. Using a Hidden Markov Model (HMM) approach with clustering we tested whether there were distinct profiles of attention pre-treatment and whether there were changes following the intervention. As a secondary aim we tested whether the distinct attentional profiles at pre-treatment predicted differential treatment outcomes. We found two distinct attentional profiles pre-treatment that we characterized as audience-focused and audience-avoidant. However, by the 1-week follow-up the two profiles were no longer meaningfully different. We found a meaningful difference between HMM groups for fear of public speaking at post-treatment b = -8.54, 95% Highest Density Interval (HDI) [-16.00, -0.90], Bayes Factor (BF) = 8.31 but not at one-week follow-up b = -5.83, 95% HDI [-13.25, 1.81], BF = 2.28. These findings provide support for heterogeneity in attentional processes among socially anxious individuals, but our findings indicate that this may change following treatment. Moreover, our results offer preliminary mechanistic evidence that patterns of avoidance may be specifically related to poorer treatment outcomes for virtual reality exposure therapy.
