To evaluate the impact of a smoke-free class competition in elementary schools in Québec, Canada before widespread dissemination of the program across the province.
In a quasiexperimental study design, 843 students in 27 schools exposed to "Mission TNT.06" were compared to 1213 students in 57 matched comparison schools. Baseline data were collected in grade 6 prior to implementation of the program. Follow-up data were collected in grade 7 after students had transitioned to secondary school.
The program improved knowledge about the harmful effects of second-hand smoke, but had no impact on knowledge about the harmful effects of smoking, attitudes about the acceptability of cigarettes, beliefs about the tobacco industry, or self-efficacy to resist peer pressure to smoke. After exposure to the program, intervention students were more likely to misreport their smoking status and to report unfavourable attitudes about classmates who smoke.
Mission TNT.06 may encourage young smokers to misreport their smoking status and to marginalise classmates who smoke. These findings prompted recommendations to conduct more in-depth evaluation of the smoke-free class competition before widespread dissemination of the program across the province.
评估加拿大魁北克省在该计划广泛传播之前，在小学开展无烟班级竞赛对学生的影响。
采用准实验设计，将暴露于“TNT.06 计划”的 27 所学校的 843 名学生与 57 所匹配对照学校的 1213 名学生进行比较。在实施该计划之前，于六年级收集基线数据。在学生升入中学后的七年级收集随访数据。
该计划提高了学生对二手烟有害影响的认识，但对吸烟有害影响、对香烟可接受性的态度、对烟草业的信念以及抵制同伴吸烟压力的自我效能感均无影响。在接触该计划后，干预组学生更有可能虚报吸烟状况，并对吸烟的同学持不利态度。
“TNT.06 计划”可能会鼓励青少年吸烟者虚报吸烟状况，并将吸烟的同学边缘化。这些发现促使建议在该计划在全省广泛传播之前，对无烟班级竞赛进行更深入的评估。
