To reverse the present stagnation in progress toward reduced smoking rates, new widely accessible treatment methods for smoking cessation must be developed and evaluated with large groups of smokers. We tested the feasibility of conducting a smoking cessation study over the Internet using a brief, self-help educational intervention. Through a direct e-mail sent from a large health information web site (WebMD), and with our presence on the Internet, we recruited 538 adult smokers to the study. Most participants (90.5%) completed all baseline questionnaires. Questionnaires showed acceptable to good reliability and were comparable with studies using paper-and-pencil methods. Participants appeared to be highly dependent on nicotine. Forty-two percent indicated being ready to quit smoking at baseline. At 1-month follow-up, 42.8% of baseline participants returned a complete follow-up questionnaire, 40% of whom indicated having made a serious quit attempt, and 8.3% of whom indicated 7-day abstinence. Most follow-up participants rated the site as at least somewhat helpful to quitting (74.9%) and reported at least a slight increased intention to quit smoking over baseline (67.3%). While Internet-enabled self-help interventions for smoking cessation are able to reach large numbers of smokers interested in quitting smoking, additional procedures are needed to retain these users for treatment and follow-up assessments.
为扭转目前在降低吸烟率方面进展停滞的局面，必须开发新的、广泛可得的戒烟治疗方法，并在大量吸烟者群体中进行评估。我们测试了通过一种简短的自助式教育干预在互联网上开展戒烟研究的可行性。通过一个大型健康信息网站（WebMD）发送的直接电子邮件，并借助我们在互联网上的宣传，我们招募了538名成年吸烟者参与该研究。大多数参与者（90.5%）完成了所有基线调查问卷。问卷显示出可接受至良好的信度，并且与使用纸笔方法的研究结果相当。参与者似乎对尼古丁高度依赖。42%的人在基线时表示准备戒烟。在1个月的随访中，42.8%的基线参与者返回了完整的随访问卷，其中40%的人表示曾认真尝试戒烟，8.3%的人表示已戒烟7天。大多数随访参与者认为该网站至少在一定程度上有助于戒烟（74.9%），并且报告称与基线相比，戒烟意愿至少略有增强（67.3%）。虽然基于互联网的自助戒烟干预能够接触到大量有戒烟意愿的吸烟者，但还需要额外的程序来留住这些用户以便进行治疗和随访评估。
