This report describes use and satisfaction of a tailored intervention delivered via Web site and handheld computer. All participants used both delivery methods. Healthy women (N = 74) aged 40 to 60 years participated in this mixed-method descriptive study. Satisfaction was measured via Computer Satisfaction Questionnaire and open-ended comments. Data on use of the handheld computer were embedded into program and captured real time. Unique Internet provider addresses tracked Web site use from March 2007 through August 2008. Results indicate 80% of participants were very to extremely satisfied. There was no significant relationship between use and satisfaction. Knowledge but not self-efficacy scores differed over time. Usage was not related to knowledge scores. Handheld computer was used most frequently during the first week, with use decreasing over 7 weeks. Personal assessment of calcium intake and feedback sections were used most frequently. Handheld computer was used by 71% of participants for 4 weeks, 55% for 6 weeks, and 29% for the full 8 weeks. Participants commented on intervention content and positive and negative aspects of the devices and keyboard. This study presented an opportunity to examine data related to actual use. This dimension of intervention fidelity is more readily available in eHealth applications than with printed information.
本报告描述了通过网站和手持计算机提供的定制干预措施的使用情况及满意度。所有参与者都使用了这两种交付方式。40至60岁的健康女性（N = 74）参与了这项混合方法描述性研究。通过计算机满意度问卷和开放式评论来衡量满意度。手持计算机的使用数据嵌入到程序中并实时捕获。通过独特的互联网服务提供商地址追踪了2007年3月至2008年8月期间的网站使用情况。结果表明，80%的参与者非常满意至极其满意。使用情况与满意度之间没有显著关系。知识得分随时间变化，而自我效能得分没有。使用情况与知识得分无关。手持计算机在第一周使用最为频繁，在7周内使用量逐渐减少。个人钙摄入量评估和反馈部分使用最为频繁。71%的参与者使用手持计算机4周，55%使用6周，29%使用了完整的8周。参与者对干预内容以及设备和键盘的积极和消极方面发表了评论。本研究提供了一个检查与实际使用相关数据的机会。与印刷信息相比，这种干预保真度维度在电子健康应用中更容易获得。
