Evaluation of Revision Effect on Criterion Validity of Multiple-Component Measuring Instruments

A method for point and interval estimation of change in criterion validity of multiple-component measuring instruments as a result of revision is outlined. The procedure is developed within the framework of covariance structure modeling, which complements earlier methods for testing change in composite reliability due to addition or deletion of components from tentative scales. The approach aids the process of constructing instruments with high validity in behavioral research that is illustrated with a pair of numerical examples.
