Longitudinal Research: The Theory, Design, and Analysis of Change
The purpose of this article is to present cutting-edge research on issues relating to the theory, design, and analysis of change. Rather than a highly technical review, our goal is to provide management scholars with a relatively nontechnical single source useful for helping them develop and evaluate longitudinal research. Toward that end, we provide readers with “check- lists” of issues to consider when theorizing and designing a longitudinal study. We also discuss the trade-offs among analytic strategies (repeated measures general linear model, random coef- ficient modeling, and latent growth modeling), circumstances in which such methods are most appropriate, and ways to analyze data when one is using each approach.
