Longitudinal methods
Abstract
This chapter looks at the psychological measurement of the same set of participants on multiple occasions, ideally using the same (or equivalent) measurement instruments. Longitudinal designs explicitly determine the temporal ordering of the observations. This temporal ordering of observations provides an enhanced ability to elucidate stability and change in individuals over time, to study time-related processes, and to establish the direction of hypothesised causal relationships.
