The purpose of this study is to compare the clinical efficacy of treatment using gaze contingent music reward therapy (GC-MRT) with attention control treatment based on a similar paradigm, for social anxiety disorder (SAD)
This study examines the possibility that the effectiveness shown for GC-MRT in the treatment of SAD leans on attention control rather than bias modification. Therefore half of the participants will receive the classic GC-MRT course of treatment while the other half a version of the task with non-emotional stimuli (geometric shapes).

| Change from baseline - the Liebowitz Social Anxiety Scale (LSAS) - Diagnostic Interview scores | The Liebowitz Social Anxiety Scale (LSAS) is a 24-item scale, each item corresponding to a situation selected on the basis of clinical experience. Each item is rated on a severity scale ranging from 0 to 3 with regard to the passing week, measuring separately two components of social anxiety, specifically, fear/anxiety and avoidance of social interaction and performance situations. The minimum and maximum values of the LSAS total score are 0 and 144, respectively, with higher scores mean worse outcome. Although the assessor may request and ask for further detail and adjust the rating based on clinical experience, this option is not often exercised, and inter-rater agreement is not considered to be a relevant concern. | at baseline, one week after end of intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline - the Social Phobia Inventory scores | This is a 17-item self-report measure of social anxiety evaluating fear, avoidance and physiological discomfort. Each item is rated on scale ranging from 0 to 4 with a total score ranging from 0 to 68. Higher scores mean worse outcome. | at baseline, one week after end of intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline -Attention Control Scale- ACS | The Attention Control Scale (ACS) assesses attention control, using 20 items rated from 1 to 4. The total score ranging from 20 to 80, with higher scores mean better outcome. | at baseline, one week after end of intervention |
| Change from baseline - Patient Health Questionnaire- PHQ9 |

| Attention Control | Behavioral | Feedback according to participants' viewing patterns, in order to strengthen their attention control |
|
| Clinical Global Impression | A global measure of clinician impression improvement and severity of illness, ranging from 1 to 7. Higher scores mean worse outcome. | at baseline, one week after end of intervention |
The Patient Health Questionnaire (PHQ9) assesses depressive symptoms using a self-report, 9 question questionnaire. Items are rated on a scale of 0-3 representing the frequency of depressive symptoms over the past 2 weeks. Scores range between 0 to 27, with higher scores mean worse outcome. |

| Viewing patterns on disgusted and neutral faces, and round/sharp shapes< representing attention bias. | gaze patterns measured using an established eye tracking task, measuring dwell time on different types of stimuli within a 4X4 matrix. | at baseline, one week after end of intervention |
| reaction times on the Flanker task, representing attention control | attention control will be measured using the established Flanker test, to assess change from baseline following treatment. | at baseline, one week after end of intervention |
