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 in a naturalistic task-based context (e.g., public speaking). In this secondary analysis we tested attentional heterogeneity among individuals (N = 21) with social anxiety disorder in the context of a virtual reality exposure treatment study. Participants completed a public speaking challenge in an immersive 360º-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 vigilant/diffuse attention control and avoidant/high attention control. By the 1-week follow-up the two profiles were no longer meaningfully different. We found a difference between HMM groups for fear at 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 is likely, but that this may change following treatment. Moreover, our results provide evidence that attentional avoidance may be related to poorer treatment outcomes.
