Persistence of Shifts in Beliefs Associated With Exposure to Alcohol Advertising Among Adolescents

Objective:The purpose of this study was to quantify the persistence of immediate changes in adolescents’ alcohol-related beliefs associated with exposure to alcohol advertising.Method:Middle school students (N = 606) carried handheld devices for 14 days and logged all of their exposures to alcohol advertisements as they naturally occurred. Perceptions of the typical person one’s age who drinks (“prototype perceptions”) and perceived norms regarding alcohol use were assessed after each exposure to advertising and at random prompts issued daily throughout the assessment period. Generalized additive modeling was used to determine how long pro-drinking shifts in beliefs persisted after exposure to advertising.Results:Following exposure to advertisements, positivity of youth’s prototype perceptions immediately increased (β = .07, 95% CI [.06, .09]) and then decreased (β = -.05, 95% CI [-.07, -.03]) over the subsequent 1.5 days, whereas perceived normativeness of alcohol use immediately increased (β = .04, 95% ...
