Study Overview
Brief Summary
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.
