Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Fear response directly post-extinction	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).	within experimental session - directly post-extinction procedure
Primary	Fear response 24 hours post-extinction	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).	24 hours following the completion of fear extinction procedures
