This article reports a pilot study of a new smoking cessation website ('StopAdvisor'), which has been developed on the basis of PRIME theory, evidence, web-design expertise and user-testing. The aims were to i) evaluate whether cessation, website usage and satisfaction were sufficiently high to warrant a randomised controlled trial (RCT) and ii) assess whether outcomes were affected by socio-economic status.
This was an uncontrolled pilot study. Two hundred and four adult daily smokers willing to make a serious quit attempt were included. All participants received support from 'StopAdvisor', which recommends a structured quit plan and a variety of evidence-based behaviour change techniques for smoking cessation. A series of tunnelled sessions and a variety of interactive menus provide tailored support for up to a month before quitting through until one-month post-quit (http://www.lifeguideonline.org/player/play/stopadvisordemonstration). The primary outcome was self-report of at least 1month of continuous abstinence collected at 2months post-enrolment and verified by saliva cotinine or anabasine. Usage was indexed by log-ins and page views. Satisfaction was assessed by dichotomous ratings of helpfulness, personal relevance, likelihood of recommendation and future use, which were collected using an online questionnaire at 2months post-enrolment. Outcomes according to socio-economic status were assessed.
At 8weeks post-enrolment, 19.6% (40/204) of participants were abstinent according to the primary outcome criteria (95% C.I.=14.1% to 25.1%). Participants viewed a mean of 133.5 pages (median=71.5) during 6.4 log-ins (median=3). A majority of respondents rated the website positively on each of the four satisfaction `ratings (range=66.7% to 75.3%). There was no evidence of an effect of socio-economic status on abstinence (OR=1.01, C.I.=0.50-2.07), usage (page-views, t(202)=0.11, p=.91; log-ins, t(202)=0.21, p=.83), or satisfaction (helpfulness, OR=1.09, C.I.=0.41-2.88; personal relevance, OR=0.55, C.I.=0.20-1.56; recommendation, OR=0.98, C.I.=0.34-2.81; use in future, OR=1.45, C.I.=0.49-4.27).
The systematic application of theory, evidence, web-design expertise, and user-testing has resulted in a website that shows sufficiently promising efficacy and usability to warrant evaluation in a RCT. The website appears to be similarly effective and acceptable to users across the social spectrum.
本文报道了一个新的戒烟网站（“StopAdvisor”）的试点研究，该网站是基于 PRIME 理论、证据、网页设计专业知识和用户测试开发的。目的是：i）评估戒烟、网站使用和满意度是否足够高，值得进行随机对照试验（RCT）；ii）评估结果是否受社会经济地位的影响。
这是一项非对照性的试点研究。纳入了 204 名愿意认真戒烟的成年每日吸烟者。所有参与者都接受了“StopAdvisor”的支持，该网站推荐了一种结构化的戒烟计划和各种基于证据的行为改变技术，以帮助戒烟。一系列的通道式会话和各种交互式菜单为戒烟前的一个月提供了定制化的支持，直到戒烟后的一个月（http://www.lifeguideonline.org/player/play/stopadvisordemonstration）。主要结局是在登记后 2 个月时自我报告至少 1 个月的持续戒烟，并通过唾液可替宁或烟碱检测验证。使用情况通过登录次数和页面浏览量来衡量。满意度通过在线问卷调查在登记后 2 个月时评估，通过四个二分制评分来评估有用性、个人相关性、推荐可能性和未来使用意愿。根据社会经济地位评估结果。
在登记后 8 周时，根据主要结局标准，有 19.6%（40/204）的参与者戒烟（95%置信区间=14.1%至 25.1%）。参与者在 6.4 次登录中平均浏览了 133.5 页（中位数=71.5）。大多数受访者对网站的四个满意度评分（范围为 66.7%至 75.3%）均给予了积极评价。没有证据表明社会经济地位对戒烟（OR=1.01，C.I.=0.50-2.07）、使用（页面浏览量，t（202）=0.11，p=.91；登录次数，t（202）=0.21，p=.83）或满意度（有用性，OR=1.09，C.I.=0.41-2.88；个人相关性，OR=0.55，C.I.=0.20-1.56；推荐可能性，OR=0.98，C.I.=0.34-2.81；未来使用意愿，OR=1.45，C.I.=0.49-4.27）有影响。
系统应用理论、证据、网页设计专业知识和用户测试的结果是开发了一个具有足够有前景的疗效和可用性的网站，值得进行 RCT 评估。该网站对社会各阶层的用户似乎同样有效和可接受。
