Introduction to Longitudinal Models

Principal speaker

Dr Kathryn Modecki

Longitudinal data afford terrific possibilities for asking unique and timely research questions. If you have access to longitudinal data, you have a number of options for testing innovative scientific hypotheses. In this workshop we will discuss different possibilities for tying longitudinal designs to specific research theories and associated methodological options.

A brief over-view will be provided to get you thinking about the different ways we might conceptualize and model change, differences, and "movement." We will cover a selected range of possibilities, with a focus on within-person (or animal, plant, or cell) change over time.

We will leverage the final 30 minutes to collectively brainstorm useful (and perhaps novel) possibilities for current projects and grant applications. And throughout, suggested references for further reading and training will be offered.

The session will be as inclusive as possible. However, you will get a great deal more out of our time together if you have brushed up on regression. Because, structural equation modelling generally (and latent growth curve modelling, growth mixture modelling, latent transition modelling, longitudinal mediation models, etc.) are all regressions, there is no better way to learn advanced methods then to get a strong handle on regression.
