互联网提供了一个有前途的渠道进行戒烟研究。互联网研究的优势之一是能够访问大量的参与者，否则他们可能不会参加戒烟试验，并能够有效地和成本效益地进行研究。为了利用互联网在临床研究中的机会，有必要建立在研究试验中使用的已知有效性的措施是可靠的，当通过互联网管理。到目前为止，还没有发表的研究检查通过互联网管理的措施的心理测量特性，以评估与戒烟相关的吸烟变量和心理社会结构（例如，压力、社会支持、戒烟方法）。本研究的目的是检查以前的戒烟方法，感知压力，抑郁症，戒烟的社会支持，吸烟的诱惑，酒精的使用，感知健康状况和收入时，通过互联网管理的措施的可靠性。本研究的参与者参加了一项关于互联网戒烟效果的随机对照试验。在基线电话评估和随机分配至母试验后，招募受试者进行可靠性子研究。电话评估后2天发送电子邮件，其中包含互联网调查的链接和当天完成调查的说明。在297名被邀请参加调查的人中，有213人在一周内完成了调查。结果表明，内部一致性和重测信度的措施检查是可比的自我管理时，通过互联网或面试官通过电话管理。
The Internet offers a promising channel to conduct smoking cessation research. Among the advantages of Internet research are the ability to access large numbers of participants who might not otherwise participate in a cessation trial, and the ability to conduct research efficiently and cost-effectively. To leverage the opportunity of the Internet in clinical research, it is necessary to establish that measures of known validity used in research trials are reliable when administered via the Internet. To date, no published studies examine the psychometric properties of measures administered via the Internet to assess smoking variables and psychosocial constructs related to cessation (e.g., stress, social support, quit methods). The purpose of the present study was to examine the reliability of measures of previous quit methods, perceived stress, depression, social support for cessation, smoking temptations, alcohol use, perceived health status, and income when administered via the Internet. Participants in the present study were enrolled in a randomized controlled trial of the efficacy of Internet smoking cessation. Following baseline telephone assessment and randomization into the parent trial, participants were recruited to the reliability substudy. An e-mail was sent 2 days after the telephone assessment with a link to the Internet survey and instructions to complete the survey that day. Of the 297 individuals invited to participate, 213 completed the survey within I week. Results indicate that the internal consistency and test-retest reliability of the measures examined are comparable when self-administered via the Internet or when interviewer-administered via telephone.
