互联网可以为大量吸烟者提供戒烟干预措施。关于互联网戒烟干预的可行性、影响范围或有效性知之甚少。事实上，没有任何数据可以说明谁参加了戒烟计划，也没有数据可以说明完成登记的人和没有完成登记的人之间的差异。本文报道了一项正在进行的随机对照试验的前764名参与者的招募和招募结果，该试验测试了广泛传播的互联网戒烟服务（www.QuitNet.com）单独和与电话咨询相结合的疗效。研究参与者通过互联网搜索引擎使用活跃的用户抽样协议招募。在研究的前16周，共有28，297人被邀请。其中，11，147人接受了邀请，5，557人筛选合格，3，614人招募，1，489人提供在线知情同意，764人确认合格并入组。在那些至少对戒烟试验感到好奇的人（n= 11，147）中，6.9%的人参加了试验。在符合条件并招募的受试者中（n= 3，614），21.1%入组。根据选择的分母，结果表明，7%至21%的有兴趣戒烟的吸烟者将参加研究试验。互联网招聘提供了独特的挑战和机会，管理样本的招聘，分析sulisamples，以确定概括性，并了解个人谁参加在线研究的特点。
The Internet can deliver smoking cessation interventions to large numbers of smokers. Little is known about the feasibility, reach, or efficacy of Internet cessation interventions. Virtually no data exist on who enrolls in cessation programs or on differences between those who complete enrollment and those who do not. This paper reports recruitment and enrollment findings for the first 764 participants in an ongoing randomized controlled trial that tested the efficacy of a widely disseminated Internet smoking cessation service (www.QuitNet.com) alone and in conjunction with telephone counseling. Study participants were recruited through Internet search engines using an active user sampling protocol. During the first 16 weeks of the study, 28,297 individuals were invited. Of those, 11,147 accepted the invitation, 5,557 screened eligible, 3,614 were recruited, 1,489 provided online informed consent, and 764 were confirmed eligible and enrolled. Of those who were at least curious about a cessation trial (n=11,147), 6.9% enrolled. Of those who were eligible and recruited (n=3,614), 21.1% enrolled. Depending on the denominator selected, results suggest that 7% to 21% of smokers interested in cessation will enroll into a research trial. Internet recruitment provides unique challenges and opportunities for managing sample recruitment, analyzing sulisamples to determine generalizability, and understanding the characteristics of individuals who participate in online research.
