PROJECT SUMMARY / ABSTRACT The Technology, Assessment, Data, and Analysis (TADA) Core will support the COBRE for Stress, Trauma, and Resilience (STAR) in leveraging novel technological, methodological, design and analytical approaches to enrich research projects and public health impact. The TADA Core will provide support for an array of innovative and state-of-the-field methods for current and future Project Leaders, the STAR faculty recruit, and Pilot Project Investigators within the STAR COBRE. Specifically, the TADA Core will offer unique expertise in leveraging technology for observational, laboratory, and intervention studies critical for (1) obtaining ecologically-valid data on stress exposures and behavioral and physiological responses with high temporal resolution, (2) novel approaches to digital phenotyping, and (3) electronically-delivered adaptive interventions. Technological innovations are rapidly progressing, and the TADA Core will provide a centralized resource for training and exchange of expertise about innovative and emerging technological approaches. The TADA Core will house unique Core equipment (e.g., eye tracking machine/computer) and software (e.g., Ilumivu) that will expand over time to meet the needs of current PLs, PPs, new PLs, and the STAR faculty recruit. The TADA Core will also provide support for additional assessments including mixed quantitative and qualitative methods, data management and electronic data capture, and sophisticated statistical analysis for longitudinal, complex data. Finally, the TADA Core will create a unique repository of data from STAR COBRE projects that will be available for secondary publications and grant applications and will serve as a resource for future Pilot Investigators, Project Leaders, and the STAR faculty recruit. The TADA Core will also offer biospecimen tracking, storage, and processing services to meet the needs of current and future projects. The aims of the TADA Core are to: (1) Provide expertise and services to support study design, technology implementation, assessment, and statistical analyses for COBRE-affiliated projects, (2) Serve as a centralized resource for research training and the exchange of methodological, technology design/ implementation, and analytic approaches related to the study of stress, trauma, and resilience, and (3) Provide expertise and services to support data management and create a repository of data that can serve as a resource for STAR COBRE investigators. Our long-term goal is to provide a sustainable resource to help investigators apply innovative and integrated methodological approaches, with matched analytic strategies to the study of stress, trauma, and resilience.
