PROJECT ABSTRACT Core A – Administrative Core The goal of the Administrative Core of the Northwell Roybal Center for Personalized Trials: Physical Activity Promotion for Persons Giving Care or Living with AD/ADRD is to establish the organizational and administrative management of the proposed center, as well as ensuring that all relevant expertise is represented in the Center where needed. Our Administrative Core will develop and provide the strategic vision, leadership, and the full range of NIH Stage Model expertise needed for the success of this Roybal Center; monitor Center clinical trials progress and provide immediate feedback; develop, identify, and use common metrics for Center productivity evaluation purposes: and finally facilitate collaboration with other Roybal Centers, with the Coordinating Center, with NIA (National Institute on Aging), and with scientists across the nation interested in advancing the initiation and maintenance of physical activity regimens personalized to care providers or those living with AD/ADRD. The overall mission of the Northwell Roybal Center for Personalized Trials is to establish an infrastructure organized per the NIH Stage Model with scientific expertise and resources to conduct Stages 0-V trials of the translational behavioral intervention development pipeline, as well as examining key MoBCs of behavior change, and so serve as a national resource for the behavioral and social intervention research community in initiating and maintaining personalized physical activity regimen for caregivers or persons living with AD/ADRD.
