Descripción detallada
This is an exploratory 8-week study with a randomized controlled, parallel group design, and will be carried out in two phases: 1) 8-week treatment phase and 2) a 3-month follow-up phase.
60 patients meeting Diagnostic and Statistical Manual IV Text Revision, (DSM-IV-TR), diagnostic criteria for social anxiety disorder will be recruited. Patients who have provided written consent, have met study criteria, and are stabilized on pharmacotherapy will be enrolled into the study.
In the treatment phase, patients will be randomized, to one of two groups 1) Breathing Focused Yoga (BFY); or 2) wait-list group.
A sub-set of 15 drug- naïve patients and matched healthy controls will undergo functional magnetic resonance imaging (fMRI) scans before and after yoga treatment.
A blood sample for genetic analysis will be taken from all SAD patients, to investigate to presence of genes linked to SAD and t treatment response.
The primary aim of the study is to determine the safety and effectiveness of Breathing Focused Yoga (BFY) in improving symptoms of SAD.
There are two secondary aims:
- To enhance the limited research data on the effect of treatment on neural circuitry in SAD, the investigators will also conduct fMRI scans on SAD patients and matched healthy controls pre- and post-BFY intervention.
- As well, to add to the literature on the genetics of SAD, the investigators will validate the links between specific gene polymorphisms and SAD that are already identified in the literature, and evaluate if they predict treatment response following BFY intervention.
Primary Hypotheses
- Subjects with Social Anxiety Disorder will show significant improvement in symptoms after BFY, compared to the wait-list group.
- Improvement in quality of life scores will be significantly greater in the BFY group compared to the wait-list group.
Secondary Hypotheses
- At baseline, the fMRI indications of neural circuitry of SAD subjects will differ from that of healthy controls.
- After yoga treatment, the fMRI indications of neural circuitry of treatment responders in the SAD group will be similar to that of healthy controls.
- The presence of specific gene polymorphisms in SAD patients will predict treatment response.

Experimental: Yoga Treatment Group
BFY will be taught by a trained yoga instructor.
Group sessions will be offered twice a week for 60 minutes each (i.e., a total of 2 hours per week), for 8 weeks.
|
The breathing focused yoga intervention is a manualized yoga protocol developed at CAMH by the Mood and Anxiety Disorders group, with yoga teacher, Ms. Tiffany Garfinkel, as the lead.
BFY incorporates postures and meditation, but there is a special focus on controlled breathing at different rates, including Ujjaji or slow inhalation, exhalation and holding of breath; Bhastrika or Kapalabhati, two types of vigorous breathing with forced exhalation; and cyclical breathing or a repeated pattern of slow, moderate and fast breathing.
