尽管使用短信收集与吸烟有关的数据大幅增加，但对回复参数的了解有限。这项研究评估了吸烟者对短信评估的回复率、响应速度、提醒的影响和响应的预测因素。数据来自两个短信戒烟干预试验，使用孕妇(n=198)和普通吸烟者(n=293)的临床样本，在3个月的戒烟计划中发送短信评估。响应率是使用来自主机网络服务器的数据计算的。分析了反应随时间的变化、提醒的影响和潜在的人口统计学(年龄、性别、种族、生育和剥夺)和吸烟(尼古丁依赖、戒烟决心、产前吸烟史、随访时吸烟状况)预测反应的因素。平均有效率为61.9%(孕期)和67.8%(一般)，累积中位反应时间分别为0.35小时(孕期)和0.64小时(一般)。应答率随着时间的推移而降低(P=0.003)，仅适用于普通吸烟者。短信提醒对回答有显著影响(P<；.001)，观察到平均增加13.8%(怀孕)和17.7%(一般)。年龄(优势比[OR]=0.95，95%可信区间[CI]0.90~1.00)和剥夺(OR=0.98，95%可信区间0.96~1.00)对妊娠吸烟者的反应和4周后一般吸烟者的不吸烟状况(OR=8.63，95%CI 3.03~24.58)的预测作用较弱。在以试验为基础的戒烟计划中进行短信评估会产生相当大比例的吸烟者的快速反应，可以使用短信提醒来增加反应。虽然对于普通吸烟者来说，几乎没有发现无反应偏见的来源，但年龄较大、生活条件较差的孕妇不太可能做出反应。这项研究表明，大多数参加戒烟试验的孕妇和普通吸烟者会通过短信回复少量关于他们吸烟的问题，大多数情况下会在收到评估短信后的1小时内做出回应。对于那些最初没有回复的人，我们的发现表明，24小时和48小时的短信提醒可能会增加少量但有意义的回复。然而，怀孕吸烟者的年龄较大、被剥夺程度较高以及普通吸烟者的复发可能会降低反应的机会。
Despite a substantial increase in use of SMS text messages for collecting smoking-related data, there is limited knowledge on the parameters of response. This study assessed response rates, response speed, impact of reminders and predictors of response to text message assessments among smokers. Data were from two SMS cessation intervention trials using clinical samples of pregnant (n = 198) and general smokers (n = 293) sent text message assessments during 3-month cessation programs. Response rates were calculated using data from the host web-server. Changes in response over time, impact of reminders and potential demographic (age, gender, ethnicity, parity, and deprivation) and smoking (nicotine dependence, determination to quit, prenatal smoking history, smoking status at follow-up) predictors of response were analyzed. Mean response rates were 61.9% (pregnant) and 67.8% (general) with aggregated median response times of 0.35 (pregnant) and 0.64 (general) hours. Response rate reduced over time (P = .003) for general smokers only. Text message reminders had a significant effect on response (Ps < .001), with observed mean increases of 13.8% (pregnant) and 17.7% (general). Age (odds ratio [OR] = 0.95, 95% confidence interval [CI] 0.90–1.00) and deprivation (OR = 0.98, 95% CI 0.96–1.00) weakly predicted response among pregnant smokers and nonsmoking status at 4 weeks follow-up (OR = 8.63, 95% CI 3.03–24.58) predicted response among general smokers. Text message assessments within trial-based cessation programs yield rapid responses from a sizable proportion of smokers, which can be increased using text reminders. While few sources of nonresponse bias were identified for general smokers, older and more deprived pregnant women were less likely to respond. This study demonstrates that most pregnant and general smokers enrolled in a cessation trial will respond to a small number of questions about their smoking sent by text message, mostly within 1 hour of being sent the assessment text message. For those who do not initially respond, our findings suggest that 24- and 48-hour text message reminders are likely to increase response a small but meaningful amount. However, older age and higher deprivation among pregnant smokers and relapse among general smokers is likely to reduce the chance of response.
