Willingness to use and pay for smoking cessation service via text-messaging among Vietnamese adult smokers, 2017.

Objectives: To examine willingness to use (WTU) and willingness to pay (WTP) for smoking cessation service via text-messaging among adult smokers in Vietnam in 2017; and to identify demographic and socioeconomic factors associated with the WTU and WTP. Methods: A cross-sectional study of 602 adult smokers who had intention to quit in the next 12 months was conducted in Vietnam in 2017. Participants were provided with the information about a mobile health (mHealth) smoking cessation service via text-messaging and asked about their willingness to use and pay for it. The contigent valuation method was used to estimate the WTP for the service, using single bound question format. Discrete choice model was applied to estimate the average WTP and its associated factors. Results: Seventy-two percent of smokers expressed willingness to use smoking cessation service via text-messaging if it were available. The average willingness to pay among those interested in using the mHealth cessation service was 82,000 VND (US$3.5). Smoking status and quit attempts in the last twelve months were associated with WTU, whereas age of the smokers and monthly income were significant predictors of WTP. Conclusion: A high proportion of Vietnamese smokers with intention to quit were interested in using smoking cessation services via text-messaging. The high level of smokers' willingness to use and pay for the text messaging cessation program indicates the mHealth methods could be a potential option for developing and delivering smoking cessation services in Vietnam.
