The current study aimed to examine the efficacy of attention bias modification (ABM) training to reduce social anxiety in a community-based sample of adolescents 15e18 years. The study used a single-blind, parallel group, randomized controlled trial design (Clinical Trials ID: NCT02270671). Participants were screened in second-level schools using a social anxiety questionnaire. 130 participants scoring 24 on the Social Phobia and Anxiety Inventory for Children (SPAI-C) were randomized to the ABM training (n ¼ 66)/placebo (n ¼ 64) group, 120 of which completed pre-, post-, and 12-week follow-up data collection including threat bias, anxiety, and depression measures. The ABM intervention included 4 weekly training sessions using a dot-probe task designed to reduce attention bias to threatening stimuli. ABM training did not alter the primary outcomes of attention bias to threat or social anxiety symptoms raising questions about the efficacy of ABM as an intervention for adolescents.
First, the experimenters were not blinded to randomization, and this could have had some degree of unintentional effect on the way in which the training was delivered to the groups. Further studies should conduct a triple-blinded trial. Second, the current trial involved one ABM session per week over four weeks. The intervals between each training session may have been too far apart for participants’ implicit learning of the intended contingencies between threat cues (avoid threat stimuli) and target location (direct attention to neutral stimuli). Using G*Power, our sample was large enough to find medium effects but not small to medium effects (significant small effects would require n ¼ 200).
