DSM-5 and the Assessment of Childhood Anxiety Disorders: Meaningful Progress,New Problems,or Persistent Diagnostic Quagmires?

Having passed the one-year anniversary of the initial DSM-5 publication, this paper presents a guiding summary of key areas of change—and lack thereof—across DSM definitions of disorders affecting anxious youth, and offers data-informed evaluations and commentaries clarifying the areas in which DSM-5 should be celebrated as a meaningful advancement in the assessment of child anxiety, diagnostic dilemmas in child anxiety assessment from previous DSM editions that remain unresolved in DSM-5, and areas in which DSM-5 may have actually introduced new problems into the assessment of child anxiety. We organize our review and commentary around five of the meaningful changes in DSM-5 with implications for the assessment of anxious youth: (1) the new classification of selective mutism as an anxiety disorder; (2) the removal of the social anxiety disorder “generalized” specifier and the new addition of a “performance-only” specifier; (3) the revised operationalization of agoraphobia and the decoupling of agoraphobia from panic disorder; (4) the creation of a new category—disruptive mood dysregulation disorder—for diagnosing youth presenting with chronic irritability and severe temper outbursts; and (5) the revised classification of anxiety disorders not otherwise specified in the DSM. We then turn our attention to discuss four areas of noted diagnostic dilemmas in the assessment of child anxiety from DSM-IV that remain unresolved in the new DSM-5: (1) the phenomenological overlap between the OCD and generalized anxiety disorder (GAD) definitions; (2) the phenomenological overlap between GAD and major depressive disorder (MDD) definitions; (3) differential diagnostic utility across the separation anxiety disorder symptoms; and (4) the extent to which youth presenting with multiple marked and persistent fears should be assigned multiple distinct diagnoses of specific phobia.
