Time-Varying Effect Modeling to Study Developmental and Dynamic Processes
by
Stephanie Lanza, Ph.D.
Professor of Biobehavioral Health and Director of the Edna Bennett Pierce Prevention Research Center at Penn State



Abstract

Time-varying effect modeling (TVEM) is a novel method that enables health, behavioral, and social scientists to examine developmental (i.e., age-varying) and dynamic (i.e., time-varying) associations. TVEM estimates regression coefficients as non-parametric functions of continuous age or time. This method can be applied to existing cross-sectional or longitudinal data to answer novel questions such as: How does the association between a particular contextual risk factor and health behavior vary across age? How do these complex associations differ across population subgroups? TVEM also can be applied to intensive longitudinal data such as ecological momentary assessments to reveal dynamic processes, addressing questions such as: How does the association between mood and craving unfold with time during a smoking quit attempt? The goal of this talk is to describe research questions that can be addressed by applying TVEM to existing data, and to provide resources for researchers interested in using the models in their own work.

About the Speaker

Stephanie Lanza, Ph.D., is a Professor of Biobehavioral Health and Director of the Edna Bennett Pierce Prevention Research Center at Penn State. She has a background in quantitative methods, human development, and substance use behaviors, with over 150 published papers in methodological and applied journals. She co-authored the book Latent Class and Latent Transition Analysis: With Applications in the Social, Behavioral, and Health Sciences (published by Wiley in 2010) and led the development of PROC LCA, a SAS procedure for fitting latent class models. Lanza recently co-authored the book Time-Varying Effect Modeling for the Behavioral, Social, and Health Sciences (published by Springer in 2021), which covers the conceptual underpinnings and technical details needed to apply this technique to analyze data (more information available here).
