Holly O'Rourke is an assistant professor with the Quantitative Methods specialization at the T. Denny Sanford School of Social and Family Dynamics. Her research focuses on the intersection of quantitative methodology and prevention research. Her statistical work is grounded in real-world questions and issues in prevention, particularly alcohol and substance use. Specifically, her research examines statistical performance of mediation models, which are used to examine how programs achieve their effects on behavioral outcomes in prevention. She is also interested in longitudinal structural equation models, particularly the latent change score (LCS) model, which assesses how behavioral outcomes change over time.
Current project include: mediated effects for longitudinal mediation with zero-inflated outcomes, best practices for simulation work with LCS models, and specification of latent change score mediation (LCSM) models.
Dr. O'Rourke is accepting new doctoral students with primary interest in quantitative methods for Fall 2021.
