Clinical Trial Summary
The objectives are:
i. To evaluate Smoke-free Teens' change in knowledge on smoking hazards, attitudes towards
smoking, tobacco control and smoking cessation, and practices for promoting smoking
prevention and cessation, ii. To evaluate the process and quality of smoke-free programmes
organized by the Smoke-free Teens in their schools/community, and iii. To measure the number
of people reached in the smoke-free programmes organized by the Smoke-free Teens.
Description:
Participants Youth between Form 1 and 4 or aged 14 to 18 in the school academic year
2019-2020 will be nominated by secondary schools, youth centres and uniform groups to
participate in the Smoke-free Teens Programme 2020-2021.
Outcomes The primary outcomes include the change in (1) knowledge on smoking hazards, (2)
attitudes towards smoking, tobacco control and smoking cessation, (3) practices for promoting
smoking prevention and cessation, and (4) the Smoke-free Teens' satisfaction on the training
camp.
The secondary outcomes are (1) the number of people participated in the school- or
community-based smoke-free programmes organised by the Smoke-free Teens, and (2) the number
of smokers advised and referred to existing smoking cessation services by the Smoke-free
Teens.
Smoke-free Teens Programme The Smoke-free teens will join six sessions of online classes via
an e-platform in October 2020 and followed by virtual training day camps through Zoom in two
days in December 2020 organized by Hong Kong Council on Smoking and Health (COSH). The online
classes will educate students the knowledge on smoking hazards, tobacco control and smoking
cessation.In addition, the teens will be taught how to deliver a brief smoking cessation
intervention using the "AWARD" Model: 1) Ask about smoking, 2) Warn the smokers that at least
half will be killed by smoking, 3) Advise to quit (reduce) as soon as possible, 4) Refer to
cessation clinics or hotlines, and 5) Do it again until the smokers quit. By the end of the
training camp, the teens should be confident and competent in delivering the brief smoking
cessation intervention to smokers. After the online classes, the teens will then break down
into groups to organize smoke-free programmes in their schools or in the community.
Survey instrument A structured questionnaire designed by the smoking cessation team, School
of Nursing, the University of Hong Kong will be used to evaluate the training camp. The
questionnaire covers four areas, including (1) knowledge on smoking hazards, (2) attitudes
towards smoking, tobacco control and smoking cessation, (3) practices for promoting smoking
prevention and cessation, and (4) self-efficacy to deliver smoking cessation advices. The
items of the questionnaire have been adopted and modified from previous studies on smoking
cessation, with well-established psychometric properties. A process evaluation form (Appendix
4) will also be developed by the smoking cessation team to assess how the teens satisfy with
the online classes and training camp, and to determine whether the content of online classes
and training camp meets the learning needs and expectations of the teens. Table 1 shows the
items that will be asked at each time point.
To evaluate the smoke-free programmes organized after the training camp, each group of the
Smoke-free Teens will be required to submit a written proposal to COSH. In addition, a final
report that contains the information about the number of people reached by the programmes,
publicity, and the process and outcomes of the programmes, will be submitted for review.
Data collection Data collection will be conducted by COSH. All Smoke-free Teens will be
invited to respond to the structured questionnaire at baseline (T1), immediately after the
online classes (T2), and 3 months later (T4). In addition, they will be asked to complete a
process evaluation form immediately after the training camp (T3). Comments and suggestions
provided by the teens in the process evaluation form will be taken into account for future
improvement of the training camp. In addition, each group of teens will have to submit the
written proposal and final report regarding the smoke-free programme to COSH at 3 months
(T4), respectively.
Statistical analysis The Statistical Package for Social Science (SPSS: Version 23; SPSS Inc.,
Chicago, IL, USA) for Windows will be employed to analyze the data. Descriptive statistics
will be used to describe the demographic characteristics of the Smoke-free Teens. Paired
samples t-test and Wilcoxon signed-rank test will be conducted to assess the change in
knowledge, attitudes and practices of the Smoke-free Teens regarding smoking, tobacco control
and smoking cessation before and after the training camp. To evaluate the smoke-free
programmes organized by the Smoke-free Teens after the training camp, descriptive statistics
will be used to report the number of people reached by the programmes, publicity, and the
process and outcomes of the programmes.
