Adolescent alcohol misuse was assessed annually (6th–12th grade) via self-report surveys. Adolescents reported annually on past-month drinking (frequency of any drinking in the past month), and past-month drunkenness (frequency of being intoxicated or drunk from alcohol in the past month) on a 1 to 5 scale (1=Not at all, 2=One time, 3=A few times, 4=About once a week, and 5=More than once a week). Over 11,000 person-waves of alcohol misuse data were collected across adolescents in the analytic sample from wave 2 (second semester of 6th grade, M age = 12.2 years) to wave 8 (12th grade, M age = 18.1 years); responses from baseline (Wave 1, first semester of 6th grade; M age = 11.8 years) were excluded from analyses as these responses were provided prior to intervention participation for all adolescents. On average, each adolescent provided 5.8 out of 7 possible alcohol misuse reports across waves 2 to 8 (SD=1.5). Examination of drinking and drunkenness distributions including observations across all person-waves revealed that approximately 73% and 86% of person-waves indicated no drinking or drunkenness respectively. As such, both
