Further studies in different patient populations, evaluating different facets of validity (including for example, the evaluation of discriminatory capacity), are necessary to confirm these proposals.
Following the pilot, extensive validity and reliability testing will be undertaken and reported, drawing on data specifically obtained to investigate internal consistency and test-retest reliability, as well as various facets of validity, especially construct and predictive validity.
Notably, many instruments contained multiple facets of validity evidence (i.e., those outlined in Table 1, such as content and internal structure validation) and multiple aspects of reliability evidence (e.g., interrater reliability, Cronbach's alpha).
Several studies examined different facets of validity, ascertaining both concurrent validity —sensitivities of 69%to100%00 %, specificities of 65%to94%94 %, and areas under the Receiver Operating Curve (AUROC) varying from 0.77 to 0.91 [ 17– 21]— and construct validity —correlations between the IQCODE and cognitive screening tests and neuropsychological tests ranging from −0.12 to −0.78 [ 17, 22].
However, Messick (1989, p.20) argued that content- and criterion-related evidence contribute to score meaning, and therefore they should be seen as facets of construct validity.
A systematic review of validity facets in portfolio research: hit the target and don't miss the point.
According to the guidelines for the standard for educational and psychological testing (American Psychological Association, 1985) two facets of the psychometric validity of the diagnostic criteria were evaluated, the convergent and the predictive validity.
A scoring rubric was used to identify and tally facets of measurement quality, including the key indicators of validity and reliability evidence.
This study has uncovered several facets of the construct validity of the K6 across gender in different age groups and over a twelve-year period.
The grounded model provide a beneficial structure for designing these two tasks, specifically with paying attention to the effect of test method facets and construct validity of this task underlying their processes.
In G theory, a universe, its facets, and the conditions for admissible observations are defined through careful construct explication, the traditional domain of validity theory.
