  1. Estimating and testing an index of responsiveness and the relationship of the index to power.

    Article - En anglais

    Responsiveness has been proposed as criterion, in addition to reliability and validity, to evaluate instruments that measure quality of life or functional status.

    The responsiveness index measures the change in a quality of life score due to a treatment relative to the variability of changes in that score within a stable control group.

    We derive the expected value, variance and distribution of the responsiveness index and give a large sample distribution for comparing the responsiveness of two different instruments.
