Expanding test–retest designs to include developmental time-lag components.

McArdle, John J., Woodcock, Richard W.·1997·Psychological Methods

Abstract

Test-retest data can reflect systematic changes over varying intervals of time in a design. This article shows how latent growth models with planned incomplete data can be used to separate psychometric components of developmental interest, including internal consistency reliability, test-practice effects, factor stability, factor growth, and state fluctuation. Practical analyses are proposed using a structural equation model for longitudinal data on multiple groups with different test-retest intervals. This approach is illustrated using 2 sets of data collected from students measured on the Woodcock-Johnson—Revised Memory and Reading scales. The results show how alternative time-lag models can be fitted and interpreted with univariate, bivariate, and multivariate data. Benefits, limitations, and extensions of this structural time-lag approach are discussed.

  • Assessing practice effects inside a longitudinal design is a difficult modeling exercise requiring assumptions because longitudinal designs explicitly targeting practice effects are rarely employed.

    “Assessing practice effects inside a longitudinal design is in and of itself a difficult modeling exercise that requires a number of assumptions, because longitudinal designs explicitly targeting practice effects are rarely employed (see Baltes et al., 1988; McArdle & Woodcock, 1997).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
