Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants allocated to intervention group will be offered the full version of SCAMPI programme as a smoking cessation tool. The programme consisted with two parts including SCAMPI WeChat Official Account for sending users quitting messages, as well as SCAMPI mini-programme for helping users to make quitting plan and track their quitting progress. SCAMPI WeChat Official Account will be programmed to send regular quitting tips to participants in intervention group. Participants can review the past messages and read the up-to-date messages whenever they want. The SCAMPI mini-programme will allow participants to create their quitting plan, track their quitting progresses, and evaluate their progresses via doing lung function screening.
Participants will be encouraged to read quitting tips on the SCAMPI WeChat Official Account and use the SCAMPI mini-programme. However, participants can determine the level of usage by their own. Participants are expected to spend 3~5 minutes per week over a 6-week period to provide their smoking statuses to the research team. Notification will be sent through WeChat messages to instruct participants how to take action to provide their smoking statuses. After providing their smoking statuses, participants will be offered with "WeChat Red Pocket" (e-currency). Fix amount of e-currency will be allocated in "WeChat red pocket" and offered by 7 sessions (including baseline assessment and 6 weeks of smoking status data collection). The whole process of the trial will be completely automatic and via social network platform.

Behaviour
Comparator / control treatment
Participants allocated in control group will be offered to have access to a restricted version of the SCAMPI programme. The restricted version will only have the SCAMPI WeChat Official Account for sending users contacts of China smoking cessation service (e.g. Quitline and Smoking Cessation Service). Participants are expected to spend 3~5 minutes per week over a 6-week period to provide their smoking statuses to the research team. Notification will be sent through WeChat messages to instruct participants how to take action to provide their smoking statuses. After providing their smoking statuses, participants will be offered with "WeChat Red Pocket" (e-currency). Fix amount of e-currency will be allocated in "WeChat red pocket" and offered by 7 sessions (including baseline assessment and 6 weeks of smoking status data collection). The whole process of the trial will be completely automatic and via social network platform.

Outcomes
Primary outcome [1] 306376 0
The primary outcome of this pilot trial will be participants’ bio-verified 30-day smoking abstinence at 6-week follow-up. At the 6-week time point, researchers will review and analyse participants’ (in both groups) smoking status in the past 30 days to identify their 30-day smoking abstinence at the planned time point. The 30-day smoking abstinence is usually used as the primary outcome measure for smoking cessation intervention trials recommended by the Society for Research on Nicotine and Tobacco (SRNT). Quit failure is defined as any cigarettes smoked in the past 30 consecutive days. This measurement is also known as the 10th level of smoking abstinence in the Chinese Standard for smoking cessation. At the 6-week time point, a Nicotine Cotinine Saliva Test kit will be sent to participants (in both groups) who report themselves with 30-day smoking abstinence to verify their smoking abstinence status.
Timepoint [1] 306376 0
Assessed weekly after randomisation for 6 weeks
Secondary outcome [1] 348427 0
Participants’ cigarette consumption reduction. Participants who reduce consumption of over 50% from baseline will be counted as successfully achieve smoking reduction. This outcome will be measured based on participants self-reported data through social network platform.
Timepoint [1] 348427 0
Assessed weekly after randomisation for 6 weeks
Secondary outcome [2] 348428 0
Prolonged smoking abstinence at 6-week follow-up. The prolonged smoking abstinence is defined as participants record no smoking following the first 7 days after the intervention start till the end of the study. The relevant data for measuring this outcome will be self-reported by participants and be collected through social network platform.

Assessed weekly after randomisation for 6 weeks
Secondary outcome [3] 348429 0
7-day smoking abstinence at 4-week – At the 4-week time point, researchers will review and analyse participants’ (in both groups) smoking status in the past 7 days to identify their 7-day smoking abstinence at this time point. 7-day smoking abstinence is defined as not a single cigarette being smoked in the past 7 days. The relevant data for measuring this outcome will be self-reported by participants and be collected through social network platform.
Timepoint [3] 348429 0
At 4 weeks after randomisation
Secondary outcome [4] 348430 0
7-day smoking abstinence at 6-week – At the 6-week time point, researchers will review and analyse participants’ (in both groups) smoking status in the past 7 days to identify their 7-day smoking abstinence at this time point. 7-day smoking abstinence is defined as not a single cigarette being smoked in the past 7 days. The relevant data for measuring this outcome will be self-reported by participants and be collected through social network platform.
Timepoint [4] 348430 0
At 6 weeks after randomisation
Secondary outcome [5] 365455 0
Participants’ compliance with SCAMPI programme. Participants’ compliance refers to participants (in both groups) provide their weekly smoking status (self-reported through social network platform) at the end of every week, as well as answering the end-of-trial questionnaires (including VAS for assessing their acceptability and MARS for assessing their satisfaction levels).
Timepoint [5] 365455 0
Assessed weekly after randomisation for 6 weeks
Secondary outcome [6] 365456 0
Number of times participants visiting SCAMPI programme. At the end of the pilot trial, researchers will review and analyse the frequencies of participants visiting the SCAMPI programme. This data will be available on the server of the programme shown as "frequencies of visit".
Timepoint [6] 365456 0
Assessed weekly after randomisation for 6 weeks
Secondary outcome [7] 365457 0

Secondary outcome [8] 365458 0
Participants’ acceptability of using SCAMPI as their smoking cessation tool. Participants’ acceptability (for both groups) of using SCAMPI will be measured by a VAS questionnaire at the end of the pilot trial. Participants’ acceptability to the SCMAPI programme will be asked by questions such as “Did the programme increase your willingness to stop smoking”, and “Did the programme encourage you to look for more stop smoking techniques?”. Each question will be answered by a 5-item scale from “Not at all” to “Very much”.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be performed at the individual level. Participants (N=318) that fulfil entry criteria and have completed baseline assessment will be randomised at a 1:1 ratio to either a intervention group or to a control group. The final randomisation lists will be concealed in the database until the point of randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be generated by the trial statistician using block randomisation with variable block sizes of 2 or 4.

Statistical methods / analysis
control panel for the data in related to the SCAMPI OA usage; (2) Wenjuanxin (it is an online questionnaire that is embed into WeChat OA system) control panel for the data in related to baseline assessment and weekly smoking status; and (3) the lean cloud database for the data in related to SCAMPI mini-programme usage. Extracted data will be entered into an Excel Database, and following cleaning and datalock, exported into SAS (version 9.4) for analysis.
Baseline characteristics
Baseline data collected from all participants will be summarised by occasional smoker and daily smoker. Continuous variables (e.g. average daily cigarette consumption) will be presented as numbers observed, means and standard deviations. Categorical variables (e.g. marital status) will be presented as frequencies and percentages. Since any differences between randomised groups at baseline could only have occurred by chance, no formal significance testing will be conducted.
Outcome relevant data
Primary and secondary outcomes will be first summarised descriptively at identified time points. Generalised linear mixed model will be used to assess the effect of the SCAMPI programme to participants’ smoking cessation outcomes.
