One of the arguments we make in this article is that the size of test-retest coefficients for a psychological construct has little to say about the kinds of processes that promote stability and change.
Researchers studying stability and change often assess variation in a psychological quality on two occasions and estimate the construct's stability via a single test-retest coefficient.
magnitude of its test-retest coefficient.
This assump- tion is largely implicit but can be inferred by noting that most research tends to focus only on two assessment waves, and in cases in which more than one wave of data are available, researchers frequently aggregate all pairwise test-retest coefficients to yield a single, composite estimate of the stability of the construct under investigation.
To see why both of these assumptions may be problematic, consider the histogram of test-retest coefficients diagrammed in the left-hand panel of Figure 1.
