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.

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.

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.

Efficacy
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.

Summary
Brief summary
This project evaluates a mobile smoking cessation programme, called as “SCAMPI”, which consists of a social network subscription account (SCAMPI WeChat Official Account) and a social network based app (SCAMPI mini-programme). The SCAMPI programme was developed based on the preferred features (functions, user experience and user interface) of its target end--users (Chinese male smokers aged 25 to 44 years).
This project will be implemented fully online. The evaluation will be run as a two-arm randomised controlled trial (RCT). After providing e-consents, participants will be randomly allocated to two groups. Participants allocated to intervention group will be offered the full version of SCAMPI programme (3 months intervention) while participants allocated to control group will be offered with restricted version of SCAMPI programme, which provides contact to general Chinese smoking cessation care (including Chinese Quitline and Local smoking cessation clinics).
Smoking status of participants from both groups will be measured weekly over a 3-month period. Participants’ prolonged smoking abstinence over the evaluation period will be used to assess the effectiveness of the SCAMPI programme for helping people to quit smoking. At the end of the project, participants will be asked about their satisfaction levels with the SCAMPI programme. Participants from both groups will be offered the SCAMPI programme with free-of-charge for supporting them to quit smoking after the study complete.
