Background:
Interest in the study of intraindividual variability is growing rapidly.
Objective:
The present collection of papers deals with both longer-term, growth and change and shorter-term intraindividual variability.
Methods:
The papers emphasize primarily the former within the context of analyzing large, longitudinal data sets. Also discussed are some key methodological matters.
Results:
Criteria to help with choosing methods and modeling with missing data are included.
Conclusions:
A promising direction is toward developing a more systematic and intensive conception of the meaning and significance of the wide variety of manifestations of intraindividual variability and integrating them into theories of aging.
