The intervention tested in this field experiment was a feedback letter sent to alcohol outlets about their individual compliance results based on a mystery shopping study.
Method: We measured compliance in 146 alcohol outlets (cafeterias, supermarkets, bars, liquor stores and youth centres) in one region in the Netherlands with 15-year-old mystery shoppers.
Purpose: To investigate the effect of a national information campaign, introduced by the Dutch Food Retail Organization, named "Under 20? Show Your ID!," on compliance with age restrictions on alcohol sales. The compliance level after the campaign was compared with a baseline compliance, that we calculated based on 458 preintervention compliance measurements.
Methods: Data were collected using the method of mystery shopping.
