Part I of this paper reviews problems in the measurement of change and, in particular, in the calculation of change scores(such as before vs. After difference scores purporting to index variance in people responsiveness to such things as instruction, stress, therapy and drugs). Part II describes a new approach to the differential measurement of change among respondents having different levels of ability and, in particular, the calculation and use of change scores.
