Across all types of reliability, when summative scales were investigated, there was a lack of consistency in the MDS items used to form cognitive and ADL subscales.
If a paper reported on more than one type of reliability, we appraised the methodological quality of these study arms separately.
In addition, a test retest analysis was not performed to ensure this type of reliability.
Furthermore, if a suitable sample of physician reviewers is selected, this type of reliability study can quantify the degree of uncertainty that exists among expert physicians about the standards of care for a particular disease management area.
Generally, this type of reliability is used for measuring the stability of a scale over time, and it is usually assessed after a short period of time.
This may well not be the type of "reliability" or "veracity" necessary to satisfy some views of the "veracity prong" of Spinelli, but we think it suffices for the practical, common sense judgment called for in making a probable cause determination.
This type of reliability is indicated due to the categorical indicators of the instrument (Green and Yang 2009, 164).
However, with the improvement in product reliability, it gradually becomes difficult to induce product failure effectively using this type of reliability test, and it cannot be used to obtain adequate failure data within an acceptable test time and sample size.
Yet in none of the Hankins examples is this type of reliability calculated or reported.
It is debatable which type of reliability, internal consistency or test-retest (TRT) reliability, is most appropriate.
Test-retest reliability is the most important type of reliability for PRO instruments used in clinical trials.
