CALDAR is organized into five Cores:
Administrative Core promotes and supports rigorous longitudinal research to enhance scientific understanding of how substance use patterns change over time and how they interact with HIV services, drug treatment services, and other service systems (e.g., criminal justice, mental health). The structure and services of the Administrative Core are designed to maintain a highly integrated and synergistic Center; facilitate research rigor, quality, and productivity; promote the professional development of new investigators; provide collaborative opportunities for new and established investigators to conduct multi-disciplinary research; collect common core measures across projects; acquire administrative data; disseminate research findings to researchers, practitioners, and policy makers; and ensure that the Center serves as a national resource for the field.
Administrative Core: Yih-Ing Hser, PhD
Core Associate Director: Michael Prendergast, PhD
Research and Methods Support Core provides services to enhance the productivity and execution of the affiliated Research Base and extends the impact of these studies by: (1) providing support for theoretical and conceptual development that guides formation of research questions, hypothesis-generation, and synthesis of findings from longitudinal research; (2) identifying and supporting state-of-the-art methods for conducting longitudinal research, including: (a) advancing mobile, web, and social media technologies for application-inspired technology innovation, (b) subject retention, (c) acquisition of administrative data; (d) measurement (in terms of assessment selection, as well as innovative technological platforms for administering measures); (e) fieldwork; and (f) regulatory issues; and (3) promoting training and dissemination of materials, techniques, and findings that support the use of longitudinal methods in drug use research.
R&MS Core Director: Christine E. Grella, PhD
Core Associate Director: Debra A. Murphy, PhD
Statistical Support and Analysis Core facilitates the selection and utilization of rigorous and emerging analytical approaches for complex longitudinal data in order to address CALDAR objectives. Core functions serve as a national resource for the field by: providing statistical consultation for qualifying and other ongoing projects and proposal development; promoting the professional development of new investigators; participating in collaborative research opportunities for new and established investigators; integrating administrative data with collaborating project data; analyzing complex longitudinal data, with particular focus on data from the expanding use of information and communication technology for intervention delivery and monitoring; comparing statistical approaches; and disseminating research findings to researchers, practitioners, and policymakers.
SS&A Core Director: Mary-Lynn Brecht, PhD
Core Associate Director: David Huang, PhD
Pilot Research Project Support Core is responsible for the support and management of pilot studies awarded by CALDAR to early-stage and new investigators as well as established investigators seeking to develop innovative longitudinal research. Core activities (e.g., providing pilot funding, assisting and monitoring pilot research projects) helps produce more carefully conceived research work that has the potential for broad impact and an increased likelihood of funding at larger scale by NIDA and other funders based on results of pilot studies. The Core also provides mentoring and career development support (e.g., for preparation of publications and presentations, developing proposal writing skills) for pilot study awardees to ensure their successful transition to independent investigators.
Pilot Core Director: Yih-Ing Hser, PhD
Core Associate Director: Mitch Karno, PhD
International Core supports and expands international research by providing a mechanism whereby CALDAR investigators link their domestic and international research projects for the mutual benefit of both. The Core focuses on two critical regions: East Asia (China, Vietnam, Taiwan, and Thailand), and the Middle East (Iraq, Egypt, Saudi Arabia, Lebanon, United Arab Emirates, Israel, and Palestine) where substance use and HIV infection are rising. The goals is to transcend national boundaries and bring together U.S. scientists with investigators from Asian and Middle Eastern countries to address shared problems in our response to substance use and HIV, develop common solutions, build collaborative research capacity, and disseminate findings to impact practice and policy
