Should You Supply was a community based campaign designed to reduce levels of problematic drinking among under-18s by discouraging inappropriate supplyof alcohol by adults, including parents. The campaign was implemented in September and October 2001 in the South Island districts of Ashburton and Waitaki.The message "Think before youbuy under-18s drink" and a range of related images were used inintensive advertising in local news media and where alcohol is sold.
This report describes the evaluation of Should You Supply. The main indicators of the campaign’s effectiveness were (i) changes in the levels at which parents supplied their teenagers(13-17years old) with alcohol forunsupervised drinking, and (ii) levels of binge drinkingamong teenagers. These indicators were measured in Ashburton and Waitaki districts as well as Clutha, a demographically similar district where the campaign was not implemented.
