73 de articoleThis 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.
This study analyzed data from 8,841 US adults with generalized anxiety disorder, finding that sexual and gender minority individuals faced significantly higher barriers to mental healthcare access compared to non-minority peers, including both cost-related delays and experiences of disrespect. The research used rigorous statistical adjustment and examined intersecting identities to inform equitable healthcare policy.
This systematic review of 34 studies covering 25,914 medical students across 18 countries found that social anxiety disorder affects approximately 46% of medical students globally, though prevalence varies significantly by assessment tool used and publication year. The analysis identified high heterogeneity in outcomes and examined demographic and contextual factors associated with social anxiety in this high-pressure academic population.
This study analyzed healthcare claims data from 2020-2023 to estimate GAD prevalence and incidence in U.S. adults, finding annual prevalence increased from 5.4% to 6.6% with women diagnosed at twice the rate of men. The findings suggest increasing GAD diagnoses may reflect better screening and recognition, underscoring the need for expanded treatment access.
This study used network analysis on clinician-administered interviews with 463 psychiatric patients to examine how panic disorder, agoraphobia, and generalized anxiety disorder symptoms interconnect. Results identified two distinct symptom clusters: panic-agoraphobia (with tightly linked physiological symptoms and catastrophic cognitions) and GAD (anchored by worry control difficulty), suggesting these conditions reflect both separate and overlapping symptom systems.
This randomized controlled trial examined core beliefs about the self in 77 individuals with GAD undergoing videoconferencing-delivered CBT. Results showed that core beliefs shifted significantly during treatment and were related to symptom reduction, despite the intervention not explicitly targeting these beliefs.
A secondary analysis of Canada's 2022 Mental Health and Access to Care Survey found lifetime SAD prevalence of 13.9% in adults, with higher rates in younger age groups (24.2% in ages 20-24 vs 6.2% in 65+). Risk factors included female gender, being Canadian-born, single status, childhood trauma, chronic health conditions, substance use disorders, low social support, and limited spirituality.
This study evaluated the accuracy of the two-item GAD-2 scale compared to the seven-item GAD-7 for screening anxiety in children with headache and epilepsy attending neurology appointments. While the GAD-2 showed strong correlation with GAD-7 and high overall accuracy (89% sensitivity, 91% specificity), it would miss 11% of children with moderate-to-severe anxiety symptoms if used as a standalone screening tool.
This study examined the emotional experiences of individuals with social anxiety disorder (SAD) versus panic disorder over 21 days using daily diary reports. Individuals with SAD showed higher shame levels and a bidirectional relationship where anxiety predicted shame/loneliness the next day and vice versa, a pattern not found in panic disorder, suggesting a distinct emotional cycle in SAD.
This longitudinal study tracked 249 patients with social anxiety disorder using network analysis to examine changes in symptom interconnections before and after 8 weeks of internet-based cognitive-behavioral therapy. Results showed that internet-based CBT modified key symptom connections, particularly the relationship between speaking tension and feeling watched, with implications for understanding treatment mechanisms.
This source addresses evidence-based guidelines for when medication is appropriately considered in treating social anxiety disorder in adult patients. It examines clinical criteria and contexts for pharmacological intervention as part of comprehensive treatment approaches.
This narrative review examines cognitive impairments associated with generalized anxiety disorder, synthesizing research on how GAD affects attention, memory, executive function, and other cognitive processes. The review provides evidence-based insights into the cognitive profile of GAD without promoting unproven treatments or cures.
A randomized controlled trial testing group psychotherapy based on the 'I-Reconstruction' method for anxiety disorders in 144 adults. The intervention targets anxiety through restoring a regulatory cycle and addressing internal conflicts, with outcomes measured via standard anxiety/depression scales over 12 months.
