Tenth grade health classes in three high schools received a special program focusing on the immediate physiological effects of cigarette smoking and the social cues influencing adoption of the smoking habit, and classes in two control schools received standard information on the long-term effects of smoking. Only subjects in the special program reported a decrease in smoking from pre to post-test; they also scored higher than controls on a knowledge test. Carbon monoxide levels were significantly lower for subjects in the special group at post-test.
三所高中的十年级健康课程接受了一个特别项目,该项目聚焦于吸烟对生理的直接影响以及影响吸烟习惯形成的社会暗示,而两所对照学校的课程则获得了关于吸烟长期影响的标准信息。只有参加特别项目的学生报告称从测试前到测试后吸烟量有所减少;他们在知识测试中的得分也高于对照组。特别项目组的学生在测试后的一氧化碳水平显著降低。
