About

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.

51 participants in 2 patient groups

TMR group
Experimental group
Description:
Patients will receive a sound while they receive a positive feedback for their performance of exposure therapy (ET). They will also receive the sound during REM sleep.
Treatment:
Behavioral: Exposure Therapy and Targeted memory reactivation during REM sleep
Control group
Active Comparator group
Description:
Patients will not receive a sound while they receive a positive feedback for their performance of exposure therapy (ET). They will receive the same sound as the experimental group during REM sleep under the same conditions.
Treatment:
Behavioral: Exposure Therapy
