Title: Measurement of Change


Measuring the magnitude of change in an attribute due to an intervention is the focus of most clinical trials. The "change from baseline" strategy is often employed, whereby scores are formed by substracting pre-test scores from post-test scores, to measure the effect of intervention. Although the unsuitability of such scores has long been discussed, they are still commonly used, even by some otherwise sophisticated investigators. Several strategies for analyzing change will be presented and discussed. Finally, the interpretation of clinical trial data and the subsequent decisions thereof shall be explained from the perspective of measurement and statistical conclusion validity.
