It is currently unknown if school-based social norms interventions are effective in preventing harmful alcohol consumption and other drug use among adolescents in Denmark. This paper describes the social norms-based programme The GOOD life and the design of a cluster-randomized controlled trial to test its effectiveness.
METHODS/DESIGN: The intervention The GOOD life is composed of three social norms components representing three different communication channels, namely face-to-face communication (normative feedback session), print communication (posters) and interactive media (web application). The intervention period of 8 weeks is preceded and followed by data collection, with the follow-up taking place 3 months after baseline. Public schools in the Region of Southern Denmark with grades 8 and 9 are invited to participate in the study and participating schools are randomly allocated to either intervention or control schools. The aim is to recruit a total of 39 schools and a sample of 1.400 pupils for the trial. An online questionnaire is conducted to examine the use of alcohol, tobacco and marijuana as well as the perceived frequency of use among peers of their own grade, which is measured before and after the intervention. Baseline data is used to develop social norms messages which are included in the three intervention components. Primary outcomes are binge drinking (more than 5 units at one occasion) and perceived frequency of binge drinking among peers, while smoking, marijuana use and alcohol-related harm will be assessed as secondary outcomes.
The GOOD life study will provide necessary insights on descriptive and injunctive norms regarding alcohol and other drug use among Danish adolescents. In addition, it will provide new knowledge and insight on the feasibility, implementation context and effectiveness of a newly developed social norms intervention in the Danish school context.

目前尚不清楚基于学校的社会规范干预措施在预防丹麦青少年有害饮酒和其他药物使用方面是否有效。本文介绍了基于社会规范的项目“美好生活”以及一项整群随机对照试验的设计，以测试其有效性。
方法/设计：“美好生活”干预措施由代表三种不同沟通渠道的三个社会规范组成部分构成，即面对面沟通（规范反馈环节）、印刷品沟通（海报）和互动媒体（网络应用程序）。在为期8周的干预期前后进行数据收集，随访在基线后3个月进行。丹麦南部地区的8年级和9年级公立学校受邀参与该研究，参与学校被随机分配到干预学校或对照学校。目标是总共招募39所学校和1400名学生参与试验。通过在线问卷来调查酒精、烟草和大麻的使用情况以及同年级学生中自我感知的使用频率，在干预前后进行测量。基线数据用于制定纳入三个干预组成部分的社会规范信息。主要结局是暴饮（一次饮用超过5个单位）以及同龄人中暴饮的自我感知频率，而吸烟、大麻使用和与酒精相关的危害将作为次要结局进行评估。
“美好生活”研究将提供关于丹麦青少年酒精和其他药物使用的描述性和指令性规范的必要见解。此外，它将提供关于一种新开发的社会规范干预措施在丹麦学校环境中的可行性、实施背景和有效性的新知识和见解。
