Self-report and neurophysiological indicators of emotion processing and regulation in social anxiety disorder.

ABSTRACT: Individuals with social anxiety disorder (SAD) report less habitual reappraisal and more frequent suppression compared to healthy controls (HC). However, it is unclear whether a neurophysiological index of emotional reactivity, the late positive potential (LPP), is aberrant in SAD or whether self-reported reappraisal or suppression relates to the LPP during on-line emotion reactivity and reappraisal. Participants with SAD (n = 51) and HC (n = 31) completed an Emotion Regulation Task. Emotion reactivity and regulation were measured via LPP when viewing negative images ('Look Negative') and when using a cognitive strategy to reduce negative affect ('Reappraise Negative'). Participants also completed a self-report measure of habitual reappraisal and suppression. SAD participants displayed heightened LPP for 'Look Negative' compared to HC. However, LPP for online reappraisal was comparable between groups. Self-reported suppression predicted the LPP during 'Look Negative' in HC, and there was a trend-level relationship in SAD. LPP findings suggest targeted reappraisal approaches may benefit individuals with SAD.
