SCH: ChangeGradients: Promoting Adolescent Health Behavior Change with Clinically Integrated Sample-Efficient Policy Gradient Methods

因为大多数青少年健康问题都可以通过行为干预来解决，而且大多数 青少年每年去看一次医疗保健提供者，健康行为干预与诊所有关- 基于医疗信息技术为提高医疗质量和 青少年随后的行为健康结果。认识到利用以下方面的进展的潜力 机器学习和虚拟叙事环境，健康行为改变的领域现在很好- 定位于设计健康行为改变系统，以扩展临床医生的触角，以实现 对青少年预防健康行为改变的重大影响。 该项目以危险行为为重点，并强调饮酒，有两个具体目标：(1) 设计、开发并迭代改进基于策略的强化学习行为改变系统 预防青少年健康，以及(2)调查临床综合样本有效政策的影响 基于梯度的青少年行为改变系统研究。这项计划将以一项 长春辐射系统对青少年患者行为影响的调查研究 来自加州大学旧金山分校儿科部门内的两个门诊初级保健诊所：Mt.锡安儿科和 青少年/青少年诊所。据推测，与长春人互动的青少年 通过减少饮酒天数，减少酗酒，提高自我效能来从事 健康的行为和避免危险物质的使用。 预计ChangegRADIENTS将为广泛的健康行为改变提供一个试验台 通过以下方式研究并作为下一代个性化预防性医疗的基础 通过计算实现的行为改变，旨在紧密结合临床实践 工作流程。通过利用其个性化提供的高度适应性交互 行为改变环境，昌吉瑞德拥有创造引人注目的巨大潜力 促进自我效能和参与健康生活方式以预防癌症的相互作用 通过改善癌症相关行为和危险因素。 Rel Evan CE(请参见结构图)： 拟议的研究将开发并现场测试一种创新的、支持计算的个性化 行为改变模型，将为广泛的健康行为改变研究提供试验台 并被设计成集成到临床实践中。通过自适应交互，Changegraadiets保持 创造引人注目的互动的巨大潜力，以提高自我效能和参与度 健康的生活方式，通过改善癌症相关行为和危险因素来预防癌症。

Because the majority of adolescent health problems are amenable to behavioral intervention and most adolescents visit a healthcare provider once a year, hea lth behavior change interventions linked to clinic- based health information technologies hold significant promise for improving healthcare quality and subsequent behavioral health outcomes for adolescents. Recognizing the potential to leverage advances in machine learning and virtual narrative environments, the field of health behavior change is now well- positioned to design health behavior change systems that extend the reach of clinicians to realize significant impacts on behavior change for adolescent preventive health. With a focus on risky behaviors and an emphasis on alcohol use, the project has two specific aims: (1) design, develop, and iteratively refine a policy-based reinforcement learning behavior change system for preventive adolescent health, and (2) investigate the impact of a clinically integrated sample-efficient policy gradient-based behavior change system on adolescent behavior. The project w ill culminate w ith an investigation of the behavioral effects of the CHANGEGRADIENTS system using adolescent patients recruited from two outpatient primary care clinics within the UCSF Department of Pediatrics: Mt. Zion Pediatrics and the Adolescent/Young Adult Clinic. It is hypothesized that adolescents who interact with CHANGEGRADIENTS with reduce number of days of alcohol use, reduce binge drinking, and increase self-efficacy to engage in healthy behavior a nd avoid risky substance use. It is anticipated that CHANGEGRADIENTS will provide a testbed for a broad range of health behavior change research and serve as the foundation for next-generation personalized preventive healthcare through computationally-enabled behavior change that is designed to be tightly integrated into clinical practice workflow. By taking advantage of the high degree of adaptive interactivity offered by its personalized behavior change environment, CHANGEGRADIENTS holds significant potential for creating compelling interactions that promote self-efficacy and engagement in healthy lifestyle behaviors to prevent cancer through improving cancer-related behaviors and risk factors. REL EVAN CE (Se e in stru cti ons): The proposed research will develop and field test an innovative computationally-enabled personalized behavior change model that will provide a testbed for a broad range of health behavior change research and is designed to be integrated into clinical practice. With adaptive interactivity, CHANGEGRADIENTS holds significant potential for creating compelling interactions that promote self-efficacy and engagement in healthy lifestyle behaviors to prevent cancer through improving cancer-related behaviors and risk factors .
