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.
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.
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.
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.
在 2017 年，调查越南成年吸烟者对通过短信进行戒烟服务的使用意愿 (WTU) 和支付意愿 (WTP)；并确定与 WTU 和 WTP 相关的人口统计学和社会经济因素。
2017 年，在越南进行了一项横断面研究，涉及 602 名有在未来 12 个月内戒烟意向的成年吸烟者。向参与者提供了有关通过短信进行移动健康 (mHealth) 戒烟服务的信息，并询问了他们对该服务的使用和支付意愿。使用单边界问题格式的条件价值评估方法来估计服务的 WTP。应用离散选择模型来估计平均 WTP 及其相关因素。
如果可以提供，72%的吸烟者表示愿意通过短信使用戒烟服务。对使用 mHealth 戒烟服务感兴趣的人的平均支付意愿为 82,000 越南盾（3.5 美元）。在过去 12 个月中的吸烟状况和戒烟尝试与 WTU 相关，而吸烟者的年龄和月收入是 WTP 的显著预测因素。
有戒烟意向的越南成年吸烟者中，有很大一部分人对通过短信使用戒烟服务感兴趣。吸烟者对短信戒烟项目的高使用意愿和支付意愿表明，mHealth 方法可能是在越南开发和提供戒烟服务的一种潜在选择。
