Modeling intraindividual variability and change: Multilevel models for (intensive) longitudinal data

The two-day course provides an overview of multilevel models for longitudinal data that stem from classical longitudinal designs (with a small number of measurement occasions per person) and from intensive longitudinal designs (ecological momentary assessment, diary methods, ambulatory assessment). Multilevel models of within-person variability and multilevel models of within-person change will be introduced. It will be shown how to analyze these models using R (lme4 package) and how to interpret the results. The course will combine short lectures, live R demonstrations, which participants can follow along, and practical exercises. Topics covered include:

  • Introduction to classes of models of within‐person variability and change
  • Multilevel models of within‐person variability
  • Multilevel growth curve models
  • Multilevel models of discontinuous change
  • Multilevel models for a small number of fixed occasions
  • Issues relevant to all model types such as centering of predictor variables, significance testing, standardized effect sizes, and power analysis

Participants should have a solid understanding of standard multiple regression analysis and basic experience with R (R Studio).
