Estimation of reliability for multiple-component measuring instruments in test-retest designs.
A covariance structure modelling method for the estimation of reliability for composites of congeneric measures in test-retest designs is outlined. The approach also allows an approximate standard error and confidence interval for scale reliability in such settings to be obtained. The procedure further permits measurement error components due to possible transient condition influences to be accounted for and evaluated, and is illustrated with a pair of examples.
