2 The corrected standard deviation of the change score is calculated using the formula where is the standard deviation of the raw scores in the 51-55 age group and is the test-retest correlation of the 27-point scale across four waves in the analysis sample. Note that the test-retest correlation for the full sample is about 0.6; the smaller value in the analysis sample reflects attenuation due to dropping those with scores below 12.
