Illness Anxiety Disorder is a recognized mental health condition characterized by excessive worry about having or acquiring a serious illness, despite minimal or no physical symptoms. It involves preoccupation with health, frequent health-related behaviors, and significant distress that impairs functioning.
This fMRI study used dynamic causal modelling to examine directed brain connectivity patterns during emotion regulation in 61 individuals with social anxiety disorder versus 41 healthy controls. Results revealed disrupted amygdala-prefrontal cortex communication in those with social anxiety, with reduced top-down modulation capacity during emotion regulation tasks.
This narrative review examines social anxiety disorder (SAD) across two presentations: overall SAD (5-13% prevalence) and performance-only SAD (0.3-0.7% prevalence), comparing their epidemiology, genetic factors, brain imaging patterns, and clinical outcomes. Performance-only SAD emerges later, affects fewer comorbidities, and shows more localized neural responses compared to overall SAD, which involves broader fronto-limbic network alterations and greater genetic influence.
This study examined baseline predictors of treatment response to group-based CBT in 90 adolescents (ages 12-17) with primary social anxiety disorder, evaluating demographic, clinical, and theory-derived factors. Results indicated that higher severity of safety behaviors and other maintaining factors predicted differential treatment outcomes at three-month follow-up.
A community sample of 315 Australian adolescents completed the SAD-DY, a DSM-5-based social anxiety measure, demonstrating good internal consistency, concurrent validity, and discriminant validity through factor analysis. The study established criterion cut-off scores for both the 10-item and a newly developed 6-item abbreviated version (SAD-DY6), enhancing clinical utility for research and practice.
