The aim was to compare the effectiveness of untailored text messages for smoking cessation to tailored text messages delivered at a higher frequency. From February 2007 to August 2009, 2030 users of an internet-based smoking cessation program with optional text message support aged 15-25 years were consecutively randomized to versions of the program that offered either tailored or untailored text messages. Thirty-day point abstinence from smoking was measured self-reportedly at 12-months follow-up. Response rates were 36.3% and 38.1% in the tailored and untailored group, respectively. We analyzed the entire study population, as well as those opting for text messages (n = 1619). In intention-to-treat analysis with multiple imputation of missing data, the odds ratio for 30-day point abstinence was 1.28 (95% CI 0.91-2.08) for the tailored compared with untailored messages. When restricting the analysis to those who had chosen to receive text messages, the corresponding odds ratio was 1.45 (95% CI 1.01-2.08). The higher long-term quit rates in the group receiving the tailored text messages compared with untailored text messages in the restricted analysis indicated that tailoring and higher frequency of text messages increases quit rates among young smokers.
目的是比较非个性化短信戒烟与更高频率发送的个性化短信戒烟的效果。2007年2月至2009年8月，2030名年龄在15 - 25岁、使用基于互联网的戒烟项目且可选择短信支持的用户被连续随机分配到提供个性化或非个性化短信的项目版本中。在12个月随访时通过自我报告测量30天点戒烟情况。个性化组和非个性化组的回复率分别为36.3%和38.1%。我们分析了整个研究人群以及选择短信服务的人群（n = 1619）。在对缺失数据进行多重插补的意向性分析中，与非个性化短信相比，个性化短信的30天点戒烟优势比为1.28（95%CI 0.91 - 2.08）。当将分析限制在选择接收短信的人群时，相应的优势比为1.45（95%CI 1.01 - 2.08）。在受限分析中，与接收非个性化短信的组相比，接收个性化短信的组长期戒烟率更高，这表明短信的个性化和更高频率可提高年轻吸烟者的戒烟率。
