To assess and compare the impact on quit attempts of online computer-tailored smoking cessation counseling reports and untailored reports, we performed a randomized controlled trial on a smoking cessation website in 2007-2008. After answering a questionnaire, current and former smokers were randomly assigned to immediately receiving either an online, individually tailored counseling report or a personalized but untailored generic report. Participants were invited by e-mail to report any smoking in the previous 24 hours, 48 hours after baseline. We used an intention-to-treat analysis, where nonrespondents at follow-up were counted as smokers. There were 2,872 participants at baseline and 2,226 at follow-up (78%). At baseline, there were 76% of current smokers (mean = 18 cigarettes/day) and 24% of recent quitters (median = 7 days of abstinence). The same proportion of smokers in both study groups had made a 24-hour quit attempt at follow-up (12.1%, P = 1.0). In baseline recent quitters, lapse/relapse rates at follow-up were similar in both groups (tailored: 25.1%, untailored: 23.5%, P = 0.64). We conclude that untailored reports were as effective as tailored reports in the short term. Even though these particular computer-tailored reports were not more effective than untailored reports, meta-analyses show that computer-tailored documents are in general more effective than untailored ones.
为了评估和比较在线计算机定制戒烟咨询报告与非定制报告对戒烟尝试的影响，我们于2007年至2008年在一个戒烟网站上进行了一项随机对照试验。在回答一份问卷后，当前吸烟者和既往吸烟者被随机分配，立即接收一份在线的、个性化定制的咨询报告或一份个性化但非定制的通用报告。通过电子邮件邀请参与者报告基线后前24小时内的任何吸烟情况。我们采用意向性分析，将随访时未回复者计为吸烟者。基线时有2872名参与者，随访时有2226名（78%）。基线时，当前吸烟者占76%（平均每天吸18支烟），近期戒烟者占24%（戒断中位数为7天）。两个研究组中相同比例的吸烟者在随访时进行了24小时的戒烟尝试（12.1%，P = 1.0）。在基线时的近期戒烟者中，两组随访时的复吸率相似（定制组：25.1%，非定制组：23.5%，P = 0.64）。我们得出结论，在短期内，非定制报告与定制报告一样有效。尽管这些特定的计算机定制报告并不比非定制报告更有效，但荟萃分析表明，一般来说，计算机定制文档比非定制文档更有效。
