Open-access Assessment of bias in facial expressions in Social Anxiety: a systematic review

This article reviews the literature on intervetion for Social Anxiety Disorder (SAD), focusing on Attention Bias Modification (CBM-A and CMB-I) and its impact on the perception of emotional facial expressions. CBM-A aims to redirect attention away from threatening stimuli, while CBM-I aims to alter the interpretation of such stimuli. The study was registered on the PROSPERO platform under the code CRD42024591700 and followed PRISMA guidelines, and included three stages: identification, screening, and eligibility. Thirteen eligible articles were analyzed based on defined descriptors, databases, and inclusion/exclusion criteria. The results indicated that CBM-A can improve attention bias and self-reported SAD symptoms, although its effectiveness varies due to methodological limitations, such as sample characteristics and subjective measures. The study highlights the need for further research on CBM-I and the integration of objective tools, like eye-tracking and neurophysiological markers, to enhance evidence-based clinical interventions.
