About

This study aims to assess the effect of mobile health (mHealth) support or financial incentives and their interactive intervention effect on smoking cessation (SC) in old smokers in Hong Kong (HK).

Full description

Low-income older smokers are disproportionally harmed by tobacco use and the evidence of effectiveness of smoking cessation (SC) intervention for this deprived group is scarce. Leveraging evidence of effectiveness of mHealth support and financial incentives in other adults, the investigators propose a scalable mHealth and/or financial incentives model using age-friendly components for the deprived older smokers.

The 2x2 factorial design consists of 2 interventions, including (1) smartphone mHealth support by scheduled age-friendly multimedia e-messages and real-time personalized behavioral supports for 3 months, and (2) an escalating incentive scheme for smoking abstinence: HK$500 for using any SC services within 6 months, and HK$1000, 1500 and 2000 for biochemically validated abstinence at 3-, 6- and 12-month, respectively.

The study aims to assess the effectiveness of two interventions and their interactive intervention effect.
