Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Investigators will examine whether post-exposure naps can be used to strengthen therapeutic extinction memories formed during exposure therapy for extreme social anxiety. Thirty-two individuals with high levels of social anxiety, evidenced by scores of 60 or greater on the Liebowitz Social Anxiety Scale, by self-report during a clinical interview and by demonstrated enhanced psychophysiological reactivity when imagining a socially stressful scenario, will be enrolled as one of four participants in one of eight successive offerings of a validated 5-session exposure-based group treatment for extreme social anxiety. The third and fourth sessions conclude with each participant delivering a speech on a topic individually chosen to elicit significant social anxiety. Following these sessions, participants will go to the sleep laboratory where two will be given a 2-hour sleep opportunity with polysomnographic (PSG) monitoring and two will be similarly instrumented but undergo 2 hours of monitored quiet wakefulness. Before and after treatment, participants will be individually assessed for social anxiety symptoms using standardized self-report instruments and a Trier Social Stress Test (TSST) modified for continuous psychophysiological monitoring. Ambulatory monitoring of home sleep will also be obtained using actigraphy and sleep diaries. The investigators hypothesize that, post treatment, those individuals who napped will show greater questionnaire-based clinical improvement as well as lesser psychophysiological reactivity during the modified TSST compared to those who remained quietly awake. The investigators further hypothesize that characteristics of sleep quality and architecture during naps, specifically durations of total sleep, REM and slow-wave sleep, as well as REM continuity, will predict greater clinical improvement and lesser psychophysiological reactivity to the TSST in those who napped following their third and fourth therapy sessions. Positive results will provide the first proof-of-principle for sleep augmentation of exposure therapy for clinically significant extreme social anxiety.
