The result showed excellent CVI (≥0.78) for sixteen tests, which comprised of one or more of the military work tasks. 0000003491 00000 n 0000058078 00000 n Validity is the degree to which an instrument measures what it is supposed to measure. •Validity could be of two kinds: content-related and criterion-related.

Fitzpatrick University of Massachusetts, Amherst The ways in which test specialists have defined content validity are reviewed and evaluated in order to determine the manner in which this validity might best be viewed. We analyzed how nurse researchers have defined and calculated the CVI, and found considerable consistency for item-level CVIs (I-CVIs). Our numerical examples indicate that the incremental Xie-Beni index with forgetting factor is superior to the other three indices tested.
