The objective of this project was to test the short term (90 days) efficacy of an automated behavioural intervention for smoking cessation, the "1-2-3 Smokefree" programme, delivered via an internet website.
Randomised control trial. Subjects surveyed at baseline, immediately post-intervention, and 90 days later.
The study and the intervention occurred entirely via the internet site. Subjects were recruited primarily via worksites, which referred potential subjects to the website.
The 351 qualifying subjects were notified of the study via their worksite and required to have internet access. Additionally, subjects were required to be over 18 years of age, smoke cigarettes, and be interested in quitting smoking in the next 30 days. Eligible subjects were randomly assigned individually to treatment or control condition by computer algorithm.
The intervention consisted of a video based internet site that presented current strategies for smoking cessation and motivational materials tailored to the user's race/ethnicity, sex, and age. Control subjects received nothing for 90 days and were then allowed access to the programme.
The primary outcome measure was abstinence from smoking at 90 day follow up.
At follow up, the cessation rate at 90 days was 24.1% (n = 21) for the treatment group and 8.2% (n = 9) for the control group (p = 0.002). Using an intent-to-treat model, 12.3% (n = 21) of the treatment group were abstinent, compared to 5.0% (n = 9) in the control group (p = 0.015).
These evaluation results suggest that a smoking cessation programme, with at least short term efficacy, can be successfully delivered via the internet.
本项目的目的是测试通过互联网网站提供的“1-2-3无烟”计划这一自动化行为戒烟干预措施的短期（90天）效果。
随机对照试验。在基线、干预后立即以及90天后对受试者进行调查。
研究和干预完全通过互联网网站进行。主要通过工作场所招募受试者，工作场所将潜在受试者推荐到该网站。
351名符合条件的受试者通过其工作场所得知该研究，并要求具备互联网接入条件。此外，受试者需年满18岁，吸烟，且在未来30天内有戒烟意愿。符合条件的受试者通过计算机算法被随机单独分配到治疗组或对照组。
干预措施包括一个基于视频的互联网网站，该网站展示了当前的戒烟策略以及根据用户的种族/民族、性别和年龄量身定制的激励材料。对照组在90天内未接受任何干预，之后可使用该计划。
主要观察指标是90天随访时的戒烟情况。
随访时，治疗组90天的戒烟率为24.1%（n = 21），对照组为8.2%（n = 9）（p = 0.002）。采用意向性分析模型，治疗组12.3%（n = 21）的受试者戒烟，对照组为5.0%（n = 9）（p = 0.015）。
这些评估结果表明，一个至少具有短期效果的戒烟计划可以通过互联网成功实施。
