This RCT examines the effectiveness of Attention Bias Modification Treatment (ABMT) as an augment to Cognitive-Behavioral Group Treatment (CBGT) for Social Anxiety Disorder (SAD) in adults. It is expected that ABMT vs. control training condition would achieve better therapeutic outcomes as indicated reduction in symptoms.
Participants from three groups (estimated 40 patients) will be offered to participate in the study
|Condition or disease||Intervention/treatment||Phase|
|Social Anxiety Disorder||Behavioral: Active Attention Bias Modification Treatment Behavioral: Placebo Attention Bias Modification Treatment||Not Applicable|
Outpatients seeking treatment for Social Anxiety Disorder (SAD) at Geha anxiety-disorders clinic will be randomized into two groups (ABMT+CBGT; placebo control+CBGT). One group will undergo an Attention Bias Modification Treatment (ABMT) aimed at diverting attention away from socially-threatening stimuli. The second group will receive a placebo-control not designed to affect attention. Both groups will also undergo a standard Cognitive-Behavioral Group Treatment (CBGT) comprising 18 weekly sessions of 1.5-hr duration (along the lines of Heimberg, Juster, Hope & Mattia 1995 and Clark & Wells 1995). Symptoms and attention bias measures will be taken at three time points: Pre-treatment, Post-treatment,and at 3-month follow-up.
The study includes the following steps: a) initial assessment of participants' psychopathology and symptom levels; b) attention bias measurement; c) 8 sessions of ABMT/placebo control delivered as part of the CBGT sessions; d) two booster ABMT/Placebo treatments will be delivered at sessions 13 and 16 of the CBGT protocol. e) post-treatment assessment will include symptom and attention bias assessments. Finally, f) a three-month follow up assessment.
The goal of the study is to to test the effectiveness of ABMT as an add-on to established CBGT protocol for social anxiety disorder.

Active Comparator: Attention Bias Modification Treatment
Participants will receive an attention bias modification protocol designed to divert attention away from socially-threatening stimuli via repeated trials of a dot-probe task.
Behavioral: Active Attention Bias Modification Treatment
Attention bias is modified using a dot-probe task. Each trial begins with a fixation cross presented in the center of the screen for 500 ms. Next, participants are presented with two stimuli depicting two faces of the same individual for 500 ms, either of two neutral faces or with one neutral face and one disgust face (i.e., the socially-threatening stimulus). Then, one of two optional probes appears in the location former occupied by one of the faces. Participants are instructed to discriminate as fast as possible between the two variants of the probe, without compromising accuracy, by pressing on two corresponding keys. The probe remains on the screen until the participant responds, after which the next trial commences. This protocol is designed to divert attention away from socially-threatening stimuli as in 80% of trials the probe appears in the location formerly occupied by the neutral face. The remaining 20% of trials include two neutral faces, with no predictive value
Other Name: Active ABMT
Placebo Comparator: placebo-control condition
Participants will receive an placebo control protocol using the same task and stimuli but not designed to change attention patterns
Behavioral: Placebo Attention Bias Modification Treatment
the Placebo ABMT is similar to the active ABMT except that this protocol is not designed to divert attention away from or toward socially-threatening stimuli as in 40% of trials the probe appears in the location formerly occupied by the neutral face and in 40% it appears in the location formally occupied by the threatening face. The remaining 20% of trials include two neutral faces
Other Name: Placebo ABMT
- Change from baseline - the Liebowitz Social Anxiety Scale - Diagnostic Interview (LSAS; Liebowitz, 1987) scores [ Time Frame: post treatment (18 weeks) and 3-month follow up ]The 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. 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 (Safren et al., 1999). It has been shown to have strong psychometric properties, including high internal consistency, strong convergent and discriminative validity and high test-retest reliability (Fresco et al., 2001; Heimberg et al., 1999)
- Change from baseline - the Social Phobia Inventory (SPIN; Connor et al., 2000) scores [ Time Frame: post treatment (18 weeks) and 3-month follow up ]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 possible total score of 68. The SPIN has been used in clinical and nonclinical samples and its psychometric properties have been found to be sound (Connor et al., 2000).
