About this study

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.

Primary outcomes

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

    Time frame: 1-2 weeks after treatment completion

    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

Secondary outcomes

  1. The Social Phobia Inventory scores

    Time frame: 1-2 weeks after treatment completion

    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.
