Although the Internet is a promising medium to offer lifestyle interventions to large amounts of people at relatively low costs and effort, actual exposure rates of these interventions fail to meet the high expectations. Since public health impact of interventions is determined by intervention efficacy and level of exposure to the intervention, it is imperative to put effort in optimal dissemination. The present project attempts to optimize the dissemination process of a new online computer tailored generic lifestyle program by carefully studying the adoption process and developing a strategy to achieve sustained use of the program.
METHODS/DESIGN: A prospective study will be conducted to yield relevant information concerning the adoption process by studying the level of adoption of the program, determinants involved in adoption and characteristics of adopters and non-adopters as well as satisfied and unsatisfied users. Furthermore, a randomized control trial will be conducted to the test the effectiveness of a proactive strategy using periodic e-mail prompts in optimizing sustained use of the new program.
Closely mapping the adoption process will gain insight in characteristics of adopters and non-adopters and satisfied and unsatisfied users. This insight can be used to further optimize the program by making it more suitable for a wider range of users, or to develop adjusted interventions to attract subgroups of users that are not reached or satisfied with the initial intervention. Furthermore, by studying the effect of a proactive strategy using period prompts compared to a reactive strategy to stimulate sustained use of the intervention and, possibly, behaviour change, specific recommendations on the use and the application of prompts in online lifestyle interventions can be developed.

虽然互联网是一种很有前途的媒介，可以以相对较低的成本和精力为大量人群提供生活方式干预，但这些干预措施的实际接触率却未能达到预期。由于干预措施的公共卫生效果取决于干预措施的效果和接触程度，因此必须努力进行最佳传播。本项目试图通过仔细研究采用过程并制定实现持续使用该计划的策略，来优化新的在线计算机个性化通用生活方式计划的传播过程。
方法/设计：将进行一项前瞻性研究，通过研究该计划的采用水平、采用过程中涉及的决定因素以及采用者和非采用者的特征以及满意和不满意用户的特征，来获得有关采用过程的相关信息。此外，将进行一项随机对照试验，以测试使用定期电子邮件提示的主动策略在优化新计划的持续使用方面的有效性。
密切映射采用过程可以深入了解采用者和非采用者以及满意和不满意用户的特征。这种洞察力可用于通过使计划更适合更广泛的用户来进一步优化计划，或者开发调整后的干预措施来吸引对初始干预措施不满意或未达到的用户群体。此外，通过研究使用定期提示的主动策略与刺激持续使用干预措施并可能改变行为的被动策略相比的效果，可以针对在线生活方式干预措施中的提示使用和应用提出具体建议。
