研究人员继续尝试开发有效的青少年烟草使用预防和戒烟计划。之前的三个学校临床研究证实了EX项目对青少年戒烟的有效性。第四项研究将EX项目应用于课堂情境。本文报告了在干预前和干预后进行的前测和后测调查的结果。方法采用随机对照试验，开发了一套8课时的课堂课程，并对来自6所项目高中和6所对照继续高中的1097名学生进行了测试。在测试前和测试后的调查中评估了项目特定知识和吸烟措施，并用于评估项目对直接结果的影响。采用多级随机系数模型分析了直接结果效应。结果：项目学生对整个项目和每个环节都给出了良好的过程评分。与对照组相比，程序组学生的正确知识反应从测试前到测试后变化更大（β=+5.5%, p=0.0003）。在项目条件下，学生每周吸烟率（β= - 6.9%, p=0.038）和未来12个月的吸烟意图（β= - 0.21, 5级量表，p=0.023）也有较大的下降。结论：sex -4的即时结果显示，与标准护理对照条件相比，学生对该计划的反应良好，知识增加，吸烟减少。
OBJECTIVEResearchers continue to try to develop effective teen tobacco use prevention and cessation programs. Three previous school clinic-based studies established the efficacy of Project EX for teen smoking cessation. This fourth study adapts Project EX to the classroom context. This paper reports the findings based on pretest and posttest surveys conducted immediately prior and post-intervention.METHODSAn eight-session classroom-based curriculum was developed and tested with a randomized controlled trial that involved a total of 1097 students in six program and six control continuation high schools. Program-specific knowledge and smoking measures were assessed at both the pretest and posttest surveys, and were used to evaluate the program's effect on the immediate outcomes. The immediate outcomes effects were analyzed with multi-level random coefficients models.RESULTSProgram students provided favorable process ratings of the overall program and each session. Compared with the students in the control condition, students in the program condition showed a greater change in correct knowledge responses from pretest to posttest (β=+5.5%, p=0.0003). Students in the program condition also experienced a greater reduction in weekly smoking (β=−6.9%, p=0.038), and intention for smoking in the next 12 months (β=−0.21 in 5-level scale, p=0.023).CONCLUSIONSEX-4 immediate outcome results revealed favorable student responses to the program, increases in knowledge, and decreases in smoking relative to a standard care control condition.
