SEM with longitudinal data

Structural equation modelling with longitudinal data can be a powerful tool in understanding behaviour over time. Although often disregarded, longitudinal invariance is essential for models where one wishes to compare mean levels over time and models depicting individual trajectories over time. Indeed, if the questionnaire was not interpreted in the same way at different time-points, how can one conclude that any observed differences in scores represented true differences?

In addition to providing an introduction to modelling using Mplus and explaining longitudinal invariance, Day 4 provides insights into path analysis with longitudinal data, auto-regressive (including cross-lagged) models and longitudinal mediation analysis.

Schedule:

• Session 1: Auto-regressive models and Longitudinal mediation
• Session 2: Longitudinal Confirmatory Factor Analysis
• Session 3: Longitudinal CFA with measurement invariance constraints
• Session 4: Recap and Quiz
