Abstract

BACKGROUND

eHealth interventions can help people change behavior (eg, quit smoking). Reminders sent via SMS text messaging or email may improve the adherence to web-based programs and increase the probability of successful behavior change; however, it is unclear whether their efficiency is affected by the modality of the communication channel.

OBJECTIVE

A 2-armed randomized control trial was conducted to compare the effect of providing reminders via SMS text messaging versus email on the adherence to an eHealth program for smoking cessation and on the probability to initiate a quit attempt.

METHODS

Smokers were recruited via an internet-based advertisement. A total of 591 participants who diverted from intended use of the program (ie, failed to log on to a session) were automatically randomized to the experimental (SMS text messaging reminder, n=304) or the active comparator (email reminder, n=287) group.

RESULTS

Unexpectedly, we found that the mode of reminder delivery did not significantly affect either the adherence, namely the number of completed program sessions, with the SMS text messaging reminder group showing a mean of 4.30 (SD 3.24) and the email reminder group showing a mean of 4.36 (SD 3.27) (t=0.197, P=.84, and Cohen d=0.016), or the outcome, namely the quit smoking attempt rate (34.2% in the SMS text messaging group vs 31.7% in the email group; χ=0.4, P=.52). Secondary analyses showed that age, gender, and education had significant effects on program adherence and education on the outcome. Moreover, we found a significant interaction effect between the mode of reminder delivery and gender on program adherence, suggesting that the effectiveness of SMS text message reminders might be different for females and males. However, this particular finding should be treated with care as it was based on post hoc subgroup analysis.

CONCLUSIONS

This study indicates that the modality of user reminders to log on increased neither the program adherence nor the probability of quitting smoking. This suggests that program developers may save costs using emails instead of SMS text messaging reminders.

摘要

背景

电子健康干预措施可以帮助人们改变行为（例如，戒烟）。通过短信或电子邮件发送提醒可以提高基于网络的程序的依从性，并增加成功改变行为的可能性；然而，尚不清楚沟通渠道的模式是否会影响其效率。

目的

进行了一项双臂随机对照试验，比较通过短信文本消息与电子邮件提供提醒对电子健康戒烟计划的依从性以及启动戒烟尝试的可能性的影响。

方法

通过基于互联网的广告招募吸烟者。共有 591 名参与者偏离了计划的使用（即，未能登录到一个会话），他们被自动随机分配到实验组（短信文本消息提醒，n=304）或主动对照组（电子邮件提醒，n=287）。

结果

出乎意料的是，我们发现提醒传递方式并没有显著影响依从性，即完成计划课程的次数，短信文本消息提醒组的平均值为 4.30（SD 3.24），电子邮件提醒组的平均值为 4.36（SD 3.27）（t=0.197，P=.84，和 Cohen d=0.016），或结果，即戒烟尝试率（短信文本消息组为 34.2%，电子邮件组为 31.7%；χ=0.4，P=.52）。二次分析表明，年龄、性别和教育对课程依从性有显著影响，而教育对结果有影响。此外，我们发现提醒传递方式和性别对课程依从性的交互效应具有显著影响，这表明短信文本消息提醒的有效性可能因女性和男性而异。然而，由于这是基于事后亚组分析的结果，因此应谨慎对待这一特定发现。
