We controlled for variables that have been previously found to be associated with adolescent HED. These covariates included gender (male or female); parental/ caregiver educational attainment (less than high school, high school or equivalent, some college, and college degree or beyond); household structure (coded as a dichotomous variable and assessed whether the respondent lived in a one- or two-parent home during the Wave 1 interview); access to alcohol in the home (“Is alcohol easily available to you in your home?”); and peer alcohol use (“Of your 3 best friends, how many drink alcohol at least once a month?”).
