Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in Social Interaction Anxiety Scale (SIAS)

    This scale measures interaction anxiety on a 5-point scale (range of scores is 0-4); the number of items is 20; the total minimum for all 20 items is 0 and the total maximum is 80; lower values consider better outcome.

    baseline to post-treatment (on average 24 weeks)

  • Change From Baseline in Social Phobia Scale (SPS)

    The scale measures social anxiety on a 5-point scale (range of score is 0-4) ; the number of items is 20; the total minimum for all 20 items is 0 and the total maximum is 80; lower values consider better outcome.

    baseline to post-treatment (on average 24 weeks)

  • Change From Baseline in Liebowitz Social Anxiety Scale (LSAS)

    The scale measures social anxiety and avoidance on a 4-point-scale (range of scores is 0-3). Blinded raters assessed social anxiety and avoidance behaviour relating to 24 social situations. Minimum for all 24 situations is 0, maximum for all 24 situations including the assessments for anxiety and avoidance is 144). Lower scores consider better outcome.

    baseline to post-treatment (on average 24 weeks)

Secondary Outcomes (2)

  • Change From Baseline in Brief Symptom Inventory (BSI)

    baseline to post-treatment (on average 24 weeks)

  • Change on Baseline in Center for Epidemiologic Studies Depression Scale (CES-D)

    baseline to post-treatment (on average 24 weeks)
