越来越多的电子保健干预措施旨在支持有利于减肥的健康行为。然而，干预措施有效性的证据有限，很少关注减肥的维持。了解最终用户的价值观和需求对于创建有意义和有效的电子健康干预措施，以及确定可能有助于成功长期减肥所需的行为改变的说服性系统设计（PSD）原则和行为改变技术（BCT）至关重要。本研究旨在深入了解电子健康干预措施的设计，以支持长期体重维持的行为改变。该研究旨在确定肥胖症患者的价值观和需求，以在减肥后保持体重，并确定PSD原则，BCT和设计要求，这些原则，BCT和设计要求可能使电子健康干预能够满足最终用户的价值观和需求。本研究提出了将PSD原则和BCT整合到电子健康干预措施的设计过程中以满足用户价值和需求的概念。在这项研究中，对肥胖症患者（n=23）和其他关键利益相关者（n=27）进行了个别访谈和焦点小组，以探索与减肥维持相关的最终用户价值观和需求。在焦点小组会议期间应用设计思维方法，以确定设计元素，并探索电子健康解决方案如何支持实现可持续减肥的需求。PSD模型和行为变化分类米吉被用来识别PSD原则和BCT集群，以满足最终用户的价值和需求。共确定了8个关键的最终用户值，反映了用户对减肥维持支持的需求：自我管理，个性化护理，自主性，感觉支持，积极的自我形象，动力，幸福和健康。目标和规划，反馈和监测，重复和替代，形成知识，社会支持，身份和自我信念是一些BCT集群确定，以解决这些概念，以及PSD原则，如个性化，定制，自我监控，表扬和建议。将最终用户的价值观和需求转化为电子保健技术的设计要素或特征的过程是设计过程的重要组成部分。据我们所知，这是第一项研究，探讨如何PSD原则和BCT可以整合时，设计电子健康自我管理干预措施，长期减肥维护。最终用户和其他主要利益攸关方强调了在设计支持持续行为改变的电子保健干预措施时应考虑的重要因素。所确定的PSD原则和BCT提供了有关设计元素和功能的见解和建议，以支持减肥维持。研究结果表明，BCT和PSD的原则相结合，可能需要在循证电子健康干预措施，以刺激动机和坚持支持健康的行为和持续减肥的维护。ClinicalTrials.gov NCT 04537988; https://clinicaltrials.gov/ct2/show/NCT04537988
An increasing number of eHealth interventions aim to support healthy behaviors that facilitate weight loss. However, there is limited evidence of the effectiveness of the interventions and little focus on weight loss maintenance. Knowledge about end user values and needs is essential to create meaningful and effective eHealth interventions, and to identify persuasive system design (PSD) principles and behavior change techniques (BCTs) that may contribute to the behavior change required for successful long-term weight loss maintenance. This study aimed to provide insight into the design of eHealth interventions supporting behavior change for long-term weight maintenance. The study sought to identify the values and needs of people with obesity aiming to maintain weight after weight loss, and to identify PSD principles, BCTs, and design requirements that potentially enable an eHealth intervention to meet end user values and needs. This study presents the concept of integrating PSD principles and BCTs into the design process of eHealth interventions to meet user values and needs. In this study, individual interviews and focus groups were conducted with people with obesity (n=23) and other key stakeholders (n=27) to explore end user values and needs related to weight loss maintenance. Design thinking methods were applied during the focus group sessions to identify design elements and to explore how eHealth solutions can support the needs to achieve sustainable weight loss maintenance. The PSD model and behavior change taxonomy by Michie were used to identify PSD principles and BCT clusters to meet end user values and needs. A total of 8 key end user values were identified, reflecting user needs for weight loss maintenance support: self-management, personalized care, autonomy, feel supported, positive self-image, motivation, happiness, and health. Goals and planning, feedback and monitoring, repetition and substitution, shaping knowledge, social support, identity, and self-belief were some of the BCT clusters identified to address these concepts, together with PSD principles such as personalization, tailoring, self-monitoring, praise, and suggestions. The process of translating end user values and needs into design elements or features of eHealth technologies is an important part of the design process. To our knowledge, this is the first study to explore how PSD principles and BCTs can be integrated when designing eHealth self-management interventions for long-term weight loss maintenance. End users and other key stakeholders highlighted important factors to be considered in the design of eHealth interventions supporting sustained behavior change. The PSD principles and BCTs identified provide insights and suggestions about design elements and features to include for supporting weight loss maintenance. The findings indicate that a combination of BCTs and PSD principles may be needed in evidence-based eHealth interventions to stimulate motivation and adherence to support healthy behaviors and sustained weight loss maintenance.
