Cognitive behavioral therapy (CBT) plus attention bias modification (ABM) reduces anxiety sensitivity and depressive symptoms in panic disorder: A pilot randomized trial.

Background: Cognitive bias theories propose that reducing threat hypervigilance in mental disorders can augment cognitive behavioral therapy (CBT) outcomes. However, no studies have tested whether adding attention bias modification (ABM) can effectively enhance CBT's effects on anxiety sensitivity (AS), electromyography (EMG), and skin conductance (SC) for panic disorder (PD). This pilot randomized controlled trial (RCT) thus aimed to evaluate the efficacy of CBT + ABM (vs. CBT plus attention training placebo; PBO) on those outcomes. Method: This study is a secondary analysis (Baker et al., 2020). Adults with PD were randomized to receive CBT + ABM (n = 11) or CBT + PBO (n = 12). Before each of the first five CBT sessions, CBT + ABM and CBT + PBO participants completed a 15‐min ABM task or attention training PBO, respectively. AS and depression severity as well as SC and EMG during habituation to a loud‐tone startle paradigm were assessed. Hierarchical Bayesian analyses were conducted. Results: During pre‐post‐treatment and pre‐follow‐up, CBM + ABM (vs. CBT + PBO) led to a notably greater reduction in ASI–Physical (between‐group d = −1.26 to −1.25), ASI‐Cognitive (d = −1.16 to −1.10), and depression severity (d = −1.23 to −0.99). However, no between‐group difference was observed for ASI‐Social, EMG, or SC indices. Discussion: Adding a brief computerized ABM intervention to CBT for PD protocols may enhance therapeutic change.
