简要总结
The purpose of this study is to develop and then test the feasibility, acceptability, and preliminary effect of a bidirectional text message smoking cessation intervention among Vietnamese smokers in Hanoi, Vietnam. The specific aim are: 1) To develop a smoking cessation text message library among Vietnamese smokers; 2) To evaluate message preferences, and the feasibility and acceptability of the bidirectional text message smoking cessation intervention; and 3) To assess the preliminary effect of a bidirectional mobile phone text message intervention on biochemically validated smoking abstinence.
详细描述
For two-arm randomized control (RCT) pilot study (AIM 3), 100 current smokers will be observed to examine the preliminary effect of bidirectional SMS smoking cessation intervention. Subjects will be randomized into two groups (intervention vs. control), and compare the carbon monoxide (CO) validated 7-day point prevalence smoking abstinence rates at 4-week follow-up between intervention group (SMS smoking cessation treatment) and control group (assessment texts only).
Investigators will administer surveys at baseline, 4- and 12-weeks, and assess daily cigarette consumption using text message surveys. After the intervention, they will randomly select 10 participants from the intervention group to attend semi-structured interviews to obtain more in-depth understanding about the usefulness, usability, and acceptability of the intervention. Findings from the pilot RCT will be used to derive an estimate of the effect size, power, and sample size for a full-scale efficacy trial.

研究组 & 干预措施
Interventional Automated mobile phone text
Subjects will receive 2 messages per day in the pre-quit phase, 3 messages per day on the quit date and the first week in the post-quit phase, and 2 messages per day in the last 3 weeks of the intervention. During the intervention, participants will receive a text question at the end of every day asking you "How many cigarettes have you smoked today?"
干预措施: Interventional Automated mobile phone text (Behavioral)
Control Texts
The intervention will consist of a 3-day pre-quit period and then a 4-week post-quit period. Participants will receive 2 text questions each week asking the number of smoking days in the past week and the average number of cigarette smoked per day.
干预措施: Control Automated mobile phone text (Behavioral)
