The Data Management and Analysis Core (DMAC) provides services to support interdisciplinary child development research. Services include support for proposal development, specific aims, study design, sampling, participant recruitment, data management, and statistical analysis for projects ranging from small pilot studies to secondary data analysis, longitudinal cohorts, and large-scale multi-site cluster randomized controlled trials. DMAC currently supports more than 20 projects and has served as a data coordinating center, data management hub, and methodologic support for projects at FPG, UNC, and other universities for more than 30 years.

Featured Project

Researchers from the UNC Gillings School of Global Public Health are teaming up with FPG to determine how North Carolina schools are operating during COVID-19. With funding from the North Carolina Policy Collaboratory, the team is led by UNC epidemiologists Kimberly Powers and Allison Aiello. In collaboration with DMAC's Sabrina Zadrozny, this interdisciplinary team will conduct a two-part study to determine what policies and practices schools have developed to minimize the spread of COVID-19 and to gauge how teachers in those schools feel they are working.
