Lifetime DSM-5 AUD diagnoses required at least 2 of the 11 criteria in the 12 months preceding the interview or previously. Diagnoses before the past 12 months required clustering of at least 2 criteria within a 1-year period. Consistent with DSM-5 criteria, AUD severity levels were classified as mild, moderate, or severe (2-3, 4-5, or ≥6 criteria, respectively). Lifetime alcohol abuse diagnoses based on DSM-IV criteria required at least 1 of the 4 abuse criteria in the 12 months preceding the interview or previously. Lifetime alcohol dependence based on DSM-IV criteria required at least 3 dependence criteria in the past 12 months or previously. Diagnoses before the past 12 months also required clustering of criteria within a 1-year period. Concordances between DSM-IV and DSM-5 12-month and lifetime AUDs in the NESARC-III were excellent (κ = 0.76 and κ = 0.61, respectively).23
