We considered using responsiveness index which relates changes to an instrument's minimally important change.
In this study, three commonly used responsiveness indices will be estimated.
Fourth, we chose to evaluate four of the more commonly used responsiveness indices in this study.
As in other studies [ 59- 62], we used responsiveness as the ability of an instrument to detect differences between two points in time (change over time) within groups.
Using responsiveness and importance-to-patients as guides, we selected best items for inclusion in a short-form, the WURSS-21[ 24].
For example, we assessed the predictive validity of the measures at baseline, but could also have assessed the predictive validity of the change values; similarly, while we used responsiveness to initial treatment as the measure, responsiveness in titration might be clinically more relevant, but would be more difficult to measure and less discriminating.
This study contrasted the use of responsiveness indices at the group level vs. individual patient level.
Schmitt and Fabio [ 20] contrasted the use of responsiveness indicators at the group level versus the individual patient level.
How can future improvements in the quality of care and the general health status of older individuals result in increased use and responsiveness to treatment?
While much has been written regarding consumer and physician attitudes toward DTC advertising, less is known relating patient characteristics, notably medication use, and responsiveness to DTC advertising.
If PTZ cameras are used, the responsiveness of such camera commands should be taken into consideration when choosing between models, as some cameras may respond or move too slowly to be useful for applications such as active tracking.
