The longitudinal cohort included adolescent and young adult participants who were followed up approximately every 2 years (mean [SD] number of time points, 3.2 [1.8]). The SSAGA was administered at each biennial assessment. Given the longitudinal design, this sample was used to examine whether prior mild-to-moderate AUD diagnoses, with and without endorsement of high-risk criteria, were associated with increased hazards of progression to severe AUD. Other well-studied correlates assessed via the SSAGA, including alcohol involvement milestones (ie, age at first drink, regular drinking, and intoxication), and MDD, ASPD, and other SUD diagnoses were also examined.
