Estimates of Effect Sizes for Mean Change Correlations Relative to T21 − T11 Changes

Correlations with changes in other variables Correlations with age
T2Avg − T1Avg 0.62 0.75
(T2Avg − T1Avg)/SD 0.29 0.41
PredT21 − PredT13 1.52 1.23
Latent difference 5.87 1.42

Note: Values were obtained by subtracting the mean correlation based on the T21 − T11 change from each type of change and then dividing the difference by the standard deviation of the T21 − T11 changes.
