Study summary

This study examines whether the ability to extract statistical properties from the environment among treatment-seeking patients with social anxiety disorder can predict therapeutic response to attention bias modification (ABM), namely, reduction in symptoms of social anxiety following ABM therapy.

Read the detailed description

All participants received 6 sessions of ABM therapy away from threat. At baseline participants also completed a gold standard statistical learning task aimed to assess participants' capacity for the extraction of statistical regularity from the environment. The aim of the study is to determine whether the basic ability to extract rules from the environment at baseline could predict clinical improvement of social anxiety symptoms.

Study arms

  • Experimental
    ABM therapy

    The attention bias modification treatment comprises of six computerized sessions, twice a week, in purpose of modulate biases in attention for threat stimuli.

    Behavioral: ABM

Interventions

  • BehavioralABM

    Participants are trained with a dot-probe task including angry-neutral faces. In 80% of trials the probe appears in place of the neutral face, and in 20% of trials in place of the angry face.

    Also known as: attention bias modification

What researchers measure

Primary outcomes

  1. The Liebowitz Social Anxiety Scale (LSAS) - Diagnostic Interview scores

    The Liebowitz Social Anxiety Scale is a clinician-rated inventory consisting of 24 items describing socially relevant situations. Each situation is rated in relation to the past week on two sub-scales ranging 0-3: level of fear and level of avoidance experienced in response to these situations. Item scores are summed to a total score ranging 0-144

    Time frame: 1-2 weeks after treatment completion

Secondary outcomes

  1. The Social Phobia Inventory scores

    The Social Phobia Inventory is a self-reported questionnaire comprised of 17 items on a 5-point scale depicting social worries and problems. Participants rate to what extent these situations have bothered them in the past week. Item scores are summed to a total score ranging 0-68.

    Time frame: 1-2 weeks after treatment completion

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2016 to primary completion in Jun 2017, 10 months.

Of 142 non-industry interventional studies with no phase under Phobia, Social, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 44. This study's 10 months is below that.

Counting every sponsor, half of 148 studies reached it within 28 months; a quarter within 14 and three quarters within 43.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 7, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
