Websites have the potential to deliver enhanced versions of targeted and tailored physical activity programs to large numbers of participants. We describe participant engagement and retention with a stage-based physical activity website in a workplace setting.
We analyzed data from participants in the website condition of a randomized trial designed to test the efficacy of a print- vs. website-delivered intervention. They received four stage-targeted e-mails over 8 weeks, with hyperlinks to the website. Both objective and self-reported website use data were collected and analyzed.
Overall, 327 were randomized to the website condition and 250 (76%) completed the follow-up survey. Forty-six percent (n = 152) visited the website over the trial period. A total of 4,114 hits to the website were recorded. Participants who entered the site spent on average 9 min per visit and viewed 18 pages. Website use declined over time; 77% of all visits followed the first e-mail.
Limited website engagement, despite the perceived usefulness of the materials, demonstrates possible constraints on the use of e-mails and websites in delivering health behavior change programs. In the often-cluttered information environment of workplaces, issues of engagement and retention in website-delivered programs require attention.
网站有潜力为大量参与者提供针对性更强、更个性化的体育活动项目升级版。我们描述了在工作场所环境中，参与者对一个基于阶段的体育活动网站的参与度和留存率。
我们分析了一项随机试验中网站组参与者的数据，该试验旨在测试印刷版与网站版干预措施的效果。他们在8周内收到了4封针对不同阶段的电子邮件，邮件带有网站超链接。我们收集并分析了客观和自我报告的网站使用数据。
总体而言，327人被随机分配到网站组，250人（76%）完成了随访调查。在试验期间，46%（n = 152）的人访问了该网站。网站总共被点击4114次。进入网站的参与者每次访问平均花费9分钟，浏览18个页面。网站使用量随时间下降；所有访问中有77%是在收到第一封电子邮件后进行的。
尽管材料被认为有用，但网站参与度有限，这表明在通过电子邮件和网站开展健康行为改变项目时可能存在限制。在工作场所通常信息繁杂的环境中，网站项目中的参与度和留存率问题需要关注。
