简要总结
With this study, the investigators aim to use sleep and dreaming in order to enhance exposure therapy for social anxiety disorder (SAD), by pairing the positive feedback phase of exposure (public talk) to an auditory stimulus during wake (associated sound) and subsequently applying this stimulus during sleep (targeted memory reactivation, TMR). Exposure therapy sessions will take place in a virtual reality (VR) environment, while physiological measures during the preparation phase of public talk such as heart rate variability (HRV), skin conductance response (SCR) and subjective level of anxiety (SUDS) will be used in order to assess treatment efficiency across the sessions. Patients with SAD according to DSM-5 criteria will be included.
The main hypothesis of this study is that participants who are presented with the associated sound during sleep (TMR group) will have reduced intensity of social anxiety compared to participants with no such association (control group), after both a full night's sleep with auditory stimulation during REM sleep in the laboratory, and after 1 week of stimulation during REM sleep at home. In addition, it is expected that fear-related dreams may correlate with anxiety levels during wakefulness after 1 week of stimulation at home.

结局指标
主要结局
Subjective Units of Distress Scale
时间窗: 1 week
Validated rating of subjective distress on a scale of 0 to 10 (higher values reflect a worse outcome)
Root mean square of the successive [R-R intervals] differences
时间窗: 1 week
The RMSSD is used to estimate the vagally mediated changes in heart rate variability.
次要结局
- Change of fear in dreams (average of fear during the second week with stimulations minus the first week without stimulations)(1 week)
- Non-specific skin conductance responses(1 week)
