This paper evaluates a smoking prevention intervention aimed at vocational school students, consisting of an existing Dutch in-school program (three lessons each lasting 50 min) and a computer-based tailored out-of-school program (three tailored letters with smoking prevention messages mailed to students' homes). Nineteen schools that already participated in the in-school program were randomly assigned to the in-school or to the combined in-school and out-of-school condition. The remaining 17 schools were randomly assigned to the out-of-school condition or to the control group. Effect outcomes were assessed at 6, 12 and 18 months after a pre-test, and were based on initiation among never-smokers and continuation among ever-smokers. Twelve months after the pre-test (post-test 2), the in-school intervention was successful in preventing vocational school students from continuing to smoke, compared with students in the control condition [odds ratio (OR) = 0.49; 95% confidence interval (CI) = 0.29-0.84]. Eighteen months after the pre-test (post-test 3), the tailored out-of-school intervention was successful in preventing smoking initiation, compared with students in the control condition (OR = 0.42; 95% CI = 0.18-0.96). The effect of the combined approach was not larger than the sum of the effects of the in-school and the out-of-school effects.
本文评估了一项针对职业学校学生的吸烟预防干预措施，该措施包括一项现有的荷兰校内项目（共三节课，每节50分钟）和一个基于计算机的个性化校外项目（向学生家中邮寄三封带有吸烟预防信息的个性化信件）。19所已经参与校内项目的学校被随机分配到仅参与校内项目组或参与校内与校外相结合项目组。其余17所学校被随机分配到校外项目组或对照组。在进行预测试后的6个月、12个月和18个月评估效果结果，评估基于从不吸烟者的吸烟起始情况和曾经吸烟者的持续吸烟情况。在预测试后12个月（测试后2），与对照组学生相比，校内干预成功地防止了职业学校学生继续吸烟[优势比（OR）=0.49；95%置信区间（CI）=0.29 - 0.84]。在预测试后18个月（测试后3），与对照组学生相比，个性化校外干预成功地预防了吸烟起始（OR = 0.42；95% CI = 0.18 - 0.96）。综合方法的效果不大于校内和校外干预效果之和。
