Axis I vs. Axis II Disorders: Outdated DSM-IV Classification
Note: The Axis I/II system was used in DSM-IV (1994–2013) and is no longer current. DSM-5 (2013) eliminated the multiaxial system.
Historical Definitions
- Axis I: Clinical disorders (anxiety, mood, psychotic, eating, substance use) – not necessarily requiring hospitalization.
- Axis II: Personality disorders and intellectual disabilities.
Modern diagnosis uses a single list with severity specifiers. Clinicians now assess all conditions together without axial separation.
