Study type | Interventional |
Text messaging can provide smokers with quitting methods, information on available smoking cessation (SC) services and social support. This kind of intervention was proven to be effective for smoking cessation. Instant messaging (IM), by sending text and pictures, could provide users with better instantaneous and inexpensive support in their time of need. However, IM intervention is understudied in smoking cessation or other health-related areas to our knowledge, its approaches and efficacy warrant further investigation. This study aims to assess the effect of the combined intervention (nicotine replacement therapy sampling, active referral, and brief advice plus a supportive semi-personalized instant messaging advice) on smoking cessation and to assess the effect of the above interventions on secondary outcomes, including quit intention and attempts, smoking reduction, level of nicotine dependence, use of nicotine replacement therapy (NRT) and SC services.

Primary | Biochemically validated abstinence | Biochemically validated abstinence (exhaled carbon monoxide <4 ppm and saliva cotinine <= 10 ng/ml) | 6-month follow-up | |
Secondary | Self-reported 7-day point prevalence abstinence | Self-reported no cigarette smoking (even a single puff) in the past 7 days | 3-month and 6-month follow-up | |

This scale consists of 2 questions: (1) how soon after waking up does a participant smoke the first cigarette with responses "within 5 minutes", "6-30 minutes", "31-60 minutes" and "after 60 minutes"; (2) how many cigarettes does a participant smoke in a day with responses "1-10", "11-20" "21-30" and ">30". | 3-month and 6-month follow-up | |
Secondary | Readiness to quit smoking | Readiness to quit smoking will be measured by a question asking the planned quit day based on the Transtheoretical Model with the following responses: within 7days, with 30 days, within 60 days, not yet decided. | 3-month and 6-month follow-up | |
Secondary | Quit attempts | Self-reported quit attempts after enrollment in the study | 3-month and 6-month follow-up | |
Secondary | Smoking reduction | Reduction in the number of cigarettes smoked daily by at least 50% of the baseline amount | 3-month and 6-month follow-up | |
Secondary | NRT use | The amount of nicotine replacement therapy (NRT) used including the sampling received at baseline, NRT received from SC services, NRT bought by participants | 3-month and 6-month follow-up | |
