In health education and behavior change interventions, process tracking monitors the delivery of an intervention and its receipt to the intended audience. A randomized controlled trial in the state of Bihar, India was conducted to help school teachers become tobacco free through appropriately designed intervention program and delivery system. We describe the results from process tracking of this intervention delivery. The intervention program was centred on six topics delivered in each school through 12 sessions over 6 successive months. The program deliverers recorded the process measures as total number of sessions and program-components implemented (fidelity); time spent conducting sessions (dose) and proportion of teachers attending at least one session (reach). The outcome measures (teachers' exposure to intervention messages and tobacco policy adoption) were assessed post-intervention. All 12 sessions were delivered in 33 out of 36 schools. Thirty-one schools implemented all six program components. In 18 schools, ≥95% of the teachers participated in one or more sessions. Thirty-three schools received 12 or more hours of dose. In 29 schools, 100% teachers reported exposure to all program messages. Tobacco policy was adopted by all schools. Thus, the intervention was generally delivered as planned and it had a positive impact on teachers and schools.
在健康教育和行为改变干预措施中，过程追踪监测干预措施的实施情况及其向目标受众的传递情况。在印度比哈尔邦进行了一项随机对照试验，旨在通过精心设计的干预计划和实施系统帮助学校教师戒烟。我们描述了该干预措施实施过程追踪的结果。干预计划围绕六个主题展开，在每个学校连续6个月通过12次课程进行授课。授课人员记录了过程指标，包括实施的课程总数和项目组成部分（保真度）；授课花费的时间（剂量）以及至少参加一次课程的教师比例（覆盖范围）。干预结束后评估了结果指标（教师接触干预信息的情况和烟草政策的采纳情况）。36所学校中的33所完成了全部12次课程。31所学校实施了所有六个项目组成部分。在18所学校中，≥95%的教师参加了一次或多次课程。33所学校获得了12小时或更长时间的授课。在29所学校中，100%的教师表示接触到了所有项目信息。所有学校都采纳了烟草政策。因此，干预措施总体上按计划实施，并且对教师和学校产生了积极影响。
