Affective dynamics and emotional reactivity in social anxiety disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Affective Science

Background:

• Social anxiety disorder (SAD) is primarily defined by anxiety in social or evaluative situations.
• Emerging evidence suggests SAD involves broader emotional reactivity beyond social contexts.
• Ecological Momentary Assessment (EMA) can track daily affective dynamics and emotional reactivity.

Purpose of the Study:

• To compare affective dynamics and emotional reactivity in adults with SAD versus other anxiety disorders and controls.
• To investigate emotional responses to daily life events in a community sample.

Main Methods:

• Utilized EMA with 236 adults (53 with SAD, 120 with other anxiety disorders, 63 controls).
• Participants completed brief electronic interviews four times daily for two weeks, assessing events and mood.
• Linear mixed models quantified emotional reactivity to daily life events.

Main Results:

• Individuals with SAD reported higher average sad and anxious mood compared to other groups.
• SAD was associated with greater mood improvement after positive events.
• SAD demonstrated increased anxious mood following negative, especially non-social, events.

Conclusions:

• Findings support a broader conceptualization of SAD beyond social contexts.
• Interventions for SAD may need to extend beyond social situations.
• EMA is a valuable tool for studying individual variability and reactivity in daily life.
