Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure for the trial is a social phobia composite measure that is created by combining scores from seven independent assessor and patient scales that are well validated measures of social phobia related symptomatology. Scores on each scale are standardised (M = 0, SD = 1) across pre-treatment and post-treatment assessments by converting to Z scores. The composite at each assessment occasion is the mean of the Z scores on that occasion. This procedure has been used in our last two social phobia trials as well as in other trials in the field. The seven scales that make up the social phobia composite are: 1. The mean assessor rating of social phobia related fear and avoidance from the anxiety disorders interview schedule for DSM-IV 2. Patient completed Social Phobia Scale 3. The Social Interaction Anxiety Scale 4. The Liebowitz Social Anxiety Scale 5. The Social Phobia and Anxiety Inventory 6. The Fear of Negative Evaluation Scale 7. The Social Phobia Weekly Summary Scale | — |
