Cognitive Behavioral Therapy (CBT) has emerged as the most extensively researched and empirically supported psychological intervention for these conditions. This comprehensive review synthesizes contemporary evidence on the efficacy, core therapeutic components, evolving applications, and implementation challenges of CBT across the anxiety disorder spectrum.</span><br><strong><span style="font-size: 14.0pt; font-family: 'Times New Roman',serif; mso-ascii-theme-font: major-bidi; mso-fareast-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; color: #0f1115; mso-font-kerning: 0pt; mso-ligatures: none;">Methods:</span></strong><span style="font-size: 14.0pt; font-family: 'Times New Roman',serif; mso-ascii-theme-font: major-bidi; mso-fareast-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; color: #0f1115; mso-font-kerning: 0pt; mso-ligatures: none;"> We conducted a narrative review of the scientific literature from January 2000 to March 2025, focusing on high-quality meta-analyses, systematic reviews, randomized controlled trials (RCTs), and key theoretical papers. Database searches included PubMed, PsycINFO, and Cochrane Library using controlled vocabulary and keywords related to CBT, specific anxiety disorders, therapeutic mechanisms, and treatment outcomes.</span><br><strong><span style="font-size: 14.0pt; font-family: 'Times New Roman',serif; mso-ascii-theme-font: major-bidi; mso-fareast-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; color: #0f1115; mso-font-kerning: 0pt; mso-ligatures: none;">Results:</span></strong><span style="font-size: 14.0pt; font-family: 'Times New Roman',serif; mso-ascii-theme-font: major-bidi; mso-fareast-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; color: #0f1115; mso-font-kerning: 0pt; mso-ligatures: none;"> Substantial evidence confirms CBT's superior efficacy compared to waitlist controls and psychological placebos, with large effect sizes (Hedges g typically >0.80) and sustained benefits. Disorder-specific protocols demonstrate strong efficacy, while transdiagnostic approaches offer comparable outcomes with improved efficiency for comorbid presentations. Core techniques—particularly exposure based on inhibitory learning principles—show robust effects, though dropout rates (15-25%) and partial response remain significant challenges. Technology-enhanced delivery methods (internet-based CBT, virtual reality) demonstrate effectiveness with improved accessibility.</span><br><strong><span style="font-size: 14.0pt; font-family: 'Times New Roman',serif; mso-ascii-theme-font: major-bidi; mso-fareast-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; color: #0f1115; mso-font-kerning: 0pt; mso-ligatures: none;">Conclusion:</span></strong><span style="font-size: 14.0pt; font-family: 'Times New Roman',serif; mso-ascii-theme-font: major-bidi; mso-fareast-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; color: #0f1115; mso-font-kerning: 0pt; mso-ligatures: none;"> While CBT maintains its status as first-line psychotherapy for anxiety disorders, important gaps exist between efficacy in controlled trials and effectiveness in routine care. Future directions should prioritize personalized treatment algorithms, mechanism-targeted interventions, cultural adaptations, and implementation strategies that improve real-world delivery. Integration with biological interventions and process-based approaches represent promising avenues for enhancing outcomes for non-responders.</span> https://www.hssres.com/article_236909_b10e3e49329605c4879b1a9dac0b54f7.pdf
