Trait Worry and Neural Correlates of Emotion Regulation

Pathological worrying is of high transdiagnostic relevance and is related to maladaptive emotion regulation processes. Dysfunctional emotion regulation and its underlying neural mechanisms might contribute to the maintenance of fear over time. Therefore, this functional magnetic resonance imaging (fMRI) study aims at investigating the association of trait worry with neural correlates of emotion regulation. Twenty-six healthy females were instructed to passively look at aversive pictures, to distract themselves with a neutral thought, or to down-and up-regulate negative feelings via cognitive reappraisal in response to repeatedly presented aversive pictures. Trait worry was not related to cognitive reappraisal but to distraction, which leads to a greater reduction of self-reported negative feelings and insula activation in individuals with higher trait worry. The current study indicates that the neural mechanisms underlying distraction seem to be altered in pathological worrying and may prevent adaptive emotional processing of aversive stimuli leading to the maintenance of fear.
