Diagnostic Criteria for Anxiety Disorders

Core Diagnostic Framework

The American Academy of Child and Adolescent Psychiatry categorizes anxiety disorders into distinct entities, each with specific diagnostic criteria that require clinically significant distress or functional impairment to distinguish pathological anxiety from normal developmental fears 1
Anxiety disorders share fundamental requirements, including excessive fear or worry that is developmentally inappropriate and out of proportion to the actual threat, which is a key criterion according to the Journal of the American Academy of Child and Adolescent Psychiatry and Depression and Anxiety 1, 2
Clinically significant distress or functional impairment in social, occupational, or academic domains is a necessary criterion for anxiety disorders, as stated in Depression and Anxiety 3, 2
Duration criteria vary by specific disorder, typically 6 months for most anxiety disorders in adults, according to Depression and Anxiety 3
Exclusion of other causes, including substance/medication effects, medical conditions, or better explanation by another mental disorder, is essential for accurate diagnosis, as noted in Depression and Anxiety 3, 2

The American Academy of Child and Adolescent Psychiatry and Depression and Anxiety suggest that specific phobia requires marked, intense fear of a specific object or situation that almost invariably provokes immediate fear, is actively avoided or endured with intense distress, is out of proportion to actual danger, and persists for at least 6 months in individuals under 18 years 4, 5
Social anxiety disorder is characterized by marked, persistent fear of social or performance situations involving unfamiliar people or possible scrutiny, with fears of acting in humiliating or embarrassing ways, and is diagnosed based on criteria including exposure to feared social situations almost always provoking anxiety, recognition that the fear is excessive or unreasonable, and avoidance or endurance with intense anxiety, as stated in Depression and Anxiety 2
Agoraphobia involves excessive fear or worry about being in situations where escape might be difficult or help unavailable should panic-like or overwhelming symptoms occur, and can exist independently of panic attacks, according to the Journal of the American Academy of Child and Adolescent Psychiatry and Depression and Anxiety 1, 4, 5

Normal developmental fears must be distinguished from pathological anxiety, and clinicians should consider the developmental context, as stated in the Journal of the American Academy of Child and Adolescent Psychiatry 1
Systematically assessing for commonly co-occurring conditions, including major depressive disorder, other anxiety disorders, substance use disorders, and in panic disorder specifically, agoraphobia, is crucial for accurate diagnosis, according to Praxis Medical Insights 6
Medical conditions that mimic anxiety symptoms, particularly for panic disorder, must be ruled out, as noted in Praxis Medical Insights 6
The GAD-7 can be used as an initial screening instrument, with scores ≥10 indicating moderate to severe anxiety requiring comprehensive diagnostic evaluation, as suggested in Praxis Medical Insights 6
