Computational Models of Health Behavior Change Dialog

描述（由申请人提供）： 在过去的40年里，在开发医学知识本体方面取得了重大进展，从而在标准化、信息共享和自动化方面取得了以前在医学中不可能的进步。相比之下，行为医学本体论的发展落后了几十年，尽管吸烟、不良饮食和缺乏身体活动等行为因素是2010年健康人群领先健康指标中一半的主要决定因素。 在这个探索性/发展性项目中，一套用于开发和部署基于行为医学概念的计算本体的自动对话式健康行为改变干预措施的软件工具将被集成并用于在体育活动和健康饮食促进领域建立三个示范系统。这些工具将用于创建与健康行为改变相关的概念本体（具体而言，在跨理论模型框架内使用的动机访谈的咨询技术），包括健康行为改变咨询的过程和技术的任务模型。这些工具将用于构建一个系统，该系统提供为期两个月的身体活动促进干预，旨在与家用电脑上的受试者进行日常接触。可用性评估后，第二个系统，促进水果和蔬菜的消费，和第三个系统，促进身体活动和水果和蔬菜的消费，将被开发，以证明本体模型的可重用性。运行时对话系统将基于由人类协作行为理论告知的对话规划器，以及FitTrack，一种客户端-服务器架构，用于通过互联网经由动画顾问向受试者的家用计算机提供健康行为改变干预。将在一项三组随机试点研究中评价所得干预系统的可用性、对行为改变理论的忠实性和有效性。本体将在Prot <$g <$中开发，并与所有任务模型和为此开发的其他软件沿着，将在项目结束时公开提供。

DESCRIPTION (provided by applicant): Significant advances have been made in developing ontologies for medical knowledge over the last 40 years, resulting in advances in standardization, information sharing and automation not previously possible in medicine. In contrast, the development of ontologies for behavioral medicine is decades behind, even though behavioral factors such as smoking, poor diet and physical inactivity are the primary determinants of half of the Healthy People 2010 Leading Health Indicators. In this exploratory/developmental project, a suite of software tools for developing and deploying automated dialog-based health behavior change interventions based on computational ontologies of concepts from behavioral medicine will be integrated and used to build three demonstration systems in the areas of physical activity and healthy eating promotion. The tools will be used to create an ontology of concepts relevant to health behavior change (specifically, counseling techniques from Motivational Interviewing used within the framework of the Transtheoretical Model), including a task model of process and techniques for health behavior change counseling. The tools will be used to build a system that provides a two-month physical activity promotion intervention designed for daily contact with subjects on their home computers. Following usability evaluations, a second system for promotion of fruit and vegetable consumption, and a third system for promotion of both physical activity and fruit and vegetable consumption, will be developed in order to demonstrate the reusability of the ontological models. The run-time dialog system will be based on a dialog planner informed by theories of human collaborative behavior, and on FitTrack, a client-server architecture for delivering health behavior change interventions over the Internet to subjects' home- computers via an animated counselor. The usability, fidelity to behavior change theory, and efficacy of the resulting intervention systems will be evaluated in a three-arm randomized pilot study. The ontology will be developed in Prot¿g¿ and, along with all task models and other software developed for this effort, will be made publicly available at the conclusion of the project.
