Social Support and Enhanced Fear Extinction

Not Applicable

Recruiting

• Conditions: Anxiety; Fear
• Interventions: Behavioral: Social Support

• Registration Number: NCT04565041
• Lead Sponsor: University of California, Los Angeles

Brief Summary

University of California, Los Angeles researchers will recruit healthy participants and anxious participants (those diagnosed with social anxiety disorder) age 18-55 years old to participate in a study examining whether the ability of social support figure reminders to enhance the extinction of fear in healthy participants extends to those with anxiety disorders.

After being recruited from the UCLA community (healthy participants, n = 50) or referred by treatment providers at the Anxiety and Depression Research Center at UCLA (anxious participants, n = 50) and undergoing a telephone screening and in-person screening, 100 participants will be enrolled in the study, with an expected recruited 150 to reach this number. During the experiment, all participants will undergo the same procedures: undergoing a fear extinction procedure in which threatening cues--cues that predict electric shock--will be paired with either an image of a social support figure (provided by participants) or an image of a smiling stranger. These pairings will be presented repeatedly in the absence of shock in order for fear extinction to occur. Participants will return for a follow-up test to determine if fear extinction was successful.

Fear response directly post-extinction	within experimental session - directly post-extinction procedure	presence of fear response as indicated by significantly higher galvanic skin response (GSR: an index of peripheral stress responding) to a previously learned fearful image (CS+) compared to a baseline comparator (CS-: never learned to be fearful).
Fear response 24 hours post-extinction	24 hours following the completion of fear extinction procedures	presence of fear response as indicated by significantly higher galvanic skin response (GSR: an index of peripheral stress responding) to a previously learned fearful image (CS+) compared to a baseline comparator (CS-: never learned to be fearful).
