Change Scores--Necessarily Anathema?
Maxwell, Scott E.; Howard, George S.
Educational and Psychological Measurement, v41 n3 p747-56 Fall 1981
This paper delineates conditions under which the use of change scores will not produce misleading results, and may perhaps be preferable to other methods of analysis. The validity of change scores in randomized pretest-posttest designs is discussed along with situations where analysis of change scores should be used. (Author/GK)
