BACKGROUND: Altered gaze in social settings is a hallmark of social anxiety; however, little research directly examines gaze in anxiety-provoking contexts among youth with anxiety disorders, limiting mechanistic insight into pediatric anxiety. The present study leveraged mobile eye-tracking technology to examine gaze behavior during a naturalistic stressor in a clinical developmental sample.
METHODS: Sixty-one youth (ages 8-17 years; 28 with anxiety disorders, 33 non-anxious controls) completed a naturalistic social stress task (public speaking in front of a videotaped classroom audience) while wearing eye-tracking glasses. Gaze behavior and state anxiety were quantified in each group during two task conditions: while giving a speech and while passively viewing the audience.
RESULTS: Anxiety-related differences emerged in state anxiety and gaze behavior. First, a significant interaction between diagnostic group and task condition on state anxiety indicated that while anxiety increased among non-anxious controls following the speech, youth with anxiety disorders reported persistently elevated anxiety across all assessments. Second, a significant interaction emerged between social anxiety symptom severity and task condition on gaze time on the audience. While youth overall showed low dwell time on the audience during speech delivery, individuals with greater social anxiety showed longer gaze on the audience during the passive viewing condition. This pattern was specific to dimensional analyses of social anxiety symptom severity.
LIMITATIONS: The current study was not sufficiently powered to examine age-related differences.
CONCLUSIONS: These findings highlight anxiety-related differences in gaze behavior in youth, providing new mechanistic insight into pediatric anxiety using mobile eye-tracking.
