The relative effectiveness of continued, lapsed, and delayed smoking prevention intervention was tested with senior high school students. The original intervention was conducted during Grades 7 through 9, with significantly fewer intervention students reporting smoking than control students. The intervention was reintroduced in the 11th grade to one-half of intervention students (continued intervention), was withdrawn from the other half (lapsed intervention), and was initiated with one-half control students (delayed intervention). The 11th-grade smoking rates of these groups were compared to those of a fourth group, a continued control group. Results showed that continued control students reported significantly less smoking than continued control students and lapsed intervention students. Additionally, the delayed intervention group exhibited smoking rates lower than the lapsed intervention and continued control groups. This finding underscores the importance of continuing smoking prevention activities, as well as initiating these activities, in senior high school years.
研究人员对高中生进行了持续、中断和延迟吸烟预防干预措施的相对有效性测试。最初的干预措施在7至9年级实施，报告吸烟的干预组学生明显少于对照组学生。在11年级时，对一半的干预组学生重新实施干预措施（持续干预），另一半不再实施干预（中断干预），并对一半的对照组学生开始实施干预（延迟干预）。将这些组在11年级的吸烟率与第四组（持续对照组）进行比较。结果显示，持续干预组学生报告的吸烟情况明显少于持续对照组学生和中断干预组学生。此外，延迟干预组的吸烟率低于中断干预组和持续对照组。这一发现强调了在高中阶段持续开展吸烟预防活动以及启动这些活动的重要性。
