Mediation models based on cross-sectional data can produce unexpected estimates, so much so that making longitudinal or causal inferences is...

Effective interventions may not be limited to changing means, but instead may also include changes to how variables affect each...

A wide variety of models can be understood in terms of the level, velocity, and acceleration of constructs: the zeroth,...

This is an introduction to dynamical systems ideas. Dynamical systems are mathematical models of one or more constructs that change...

Historically, it has been easier to describe differences between groups of people, rather than describe the dynamic ways that people...

The relationship between global emotion control beliefs and daily affect reports across 56 days were assessed in a sample of...

Stochastic differential equation (SDE) models are a promising method for modeling intraindividual change and variability. This method uses structural equation...

Intraindividual measures, such as intraindividual standard deviation or coefficient of variation, are incomplete representations variability. Studying variability can be made...

Resilience is often considered both a trait and a process. The current study proposes a new way to conceptualize resilience-as-process...

Using embedded and observed data matrices, a statistical approach to differential equation modeling is presented. This approach appears robust to...
