Unhealthy dietary patterns and insufficient physical activity (PA) are associated with negative health outcomes, such as cardiovascular diseases, type 2 diabetes, cancer, overweight, and obesity. This makes the promotion of healthy dietary and PA behaviors a public health priority.
This paper describes the development, design, and evaluation protocol of a Web-based computer-tailored (CT) dietary and PA promotion intervention, MyLifestyleCoach. A Web-based format was chosen for its accessibility and large-scale reach and low-cost potential. To achieve effective and persistent behavioral change, this innovative intervention is tailored to individual characteristics and is based on the self-determination theory and motivational interviewing (MI).
The 6 steps of the intervention mapping protocol were used to systematically develop MyLifestyleCoach based on the existing effective CT PA promotion intervention I Move. The MyLifestyleCoach intervention consists of 2 modules: I Move, which is aimed at promoting PA, and I Eat, which is aimed at promoting healthy eating. Development of the I Eat module was informed by the previously developed I Move. Both modules were integrated to form the comprehensive MyLifestyleCoach program. Furthermore, I Move was slightly adapted, for example, the new Dutch PA guidelines were implemented. A randomized controlled trial consisting of an intervention condition and waiting list control group will be used to evaluate the effectiveness of the intervention on diet and PA.
Self-reported measures take place at baseline, 6 months, and 12 months after baseline. Enrollment started in October 2018 and will be completed in June 2020. Data analysis is currently under way, and the first results are expected to be submitted for publication in 2020.
MyLifestyleCoach is one of the first interventions to translate and apply self-determination theory and techniques from MI in Web-based computer tailoring for an intervention targeting PA and dietary behavior. Intervention mapping served as a blueprint for the development of this intervention. We will evaluate whether this approach is also successful in promoting eating healthier and increasing PA using an randomized controlled trial by comparing the intervention to a waiting list control condition. The results will provide an insight into the short- and long-term efficacy and will result in recommendations for the implementation and promotion of healthy eating and PA among adults in the Netherlands.

不健康的饮食模式和缺乏体育活动与负面健康结果相关，如心血管疾病、2型糖尿病、癌症、超重和肥胖。这使得促进健康的饮食和体育活动行为成为公共卫生的优先事项。
本文描述了一种基于网络的计算机定制（CT）饮食和体育活动促进干预措施MyLifestyleCoach的开发、设计和评估方案。选择基于网络的形式是因为其可及性、大规模覆盖范围和低成本潜力。为了实现有效且持久的行为改变，这种创新干预措施根据个体特征进行定制，并基于自我决定理论和动机性访谈（MI）。
干预映射方案的6个步骤被用于在现有的有效的CT体育活动促进干预措施“I Move”的基础上系统地开发MyLifestyleCoach。MyLifestyleCoach干预措施由2个模块组成：旨在促进体育活动的“I Move”和旨在促进健康饮食的“I Eat”。“I Eat”模块的开发借鉴了之前开发的“I Move”。两个模块整合形成了综合的MyLifestyleCoach项目。此外，对“I Move”进行了一些调整，例如实施了新的荷兰体育活动指南。一项由干预组和等待名单对照组组成的随机对照试验将用于评估该干预措施对饮食和体育活动的有效性。
自我报告的测量在基线、基线后6个月和12个月进行。招募于2018年10月开始，将于2020年6月完成。数据分析目前正在进行，预计第一批结果将于2020年提交发表。
MyLifestyleCoach是首批将自我决定理论和动机性访谈技术转化并应用于基于网络的计算机定制，以针对体育活动和饮食行为进行干预的措施之一。干预映射为该干预措施的开发提供了蓝图。我们将通过将干预组与等待名单对照组进行比较的随机对照试验，评估这种方法在促进更健康饮食和增加体育活动方面是否也取得成功。结果将提供对短期和长期疗效的洞察，并将为在荷兰成年人中实施和促进健康饮食及体育活动提供建议。
