validity

 [vah-lid´ĭ-te]
the extent to which a measuring device measures what it intends or purports to measure.
construct validity the degree to which an instrument measures the characteristic being investigated; the extent to which the conceptual definitions match the operational definitions.
content validity verification that the method of measurement actually measures what it is expected to measure; see also face validity.
external validity the extent to which study findings can be generalized beyond the sample used in the study.
face validity a type of content validity, determining the suitability of a given instrument as a source of data on the subject under investigation, using common-sense criteria.
internal validity the extent to which the effects detected in a study are truly caused by the treatment or exposure in the study sample, rather than being due to other biasing effects of extraneous variables.
predictive validity the effectiveness of one set of test or research results as a predictor of the outcome of future experiments or tests.

pre·dic·tive va·lid·i·ty

criterion-related validity used to predict performance in a real-life task at a future time. See: construct validity, criterion-related validity.

predictive validity

validity of a test or a measurement tool that is established by demonstrating the ability of a test or measure to predict the results of an analysis of the same data made with another test instrument or measurement tool. See also validity.

pre·dic·tive va·li·di·ty

(prē-diktiv vă-lidi-tē)
Criterion-related standard used to predict performance in a real-life task at a future time.

However, validity has been discussed in the literature in terms of content validity, predictive validity and construct validity as well.
However, these validity estimates may not accurately represent the predictive validity of perceptual ability tests, since the classification of tests under their perceptual test category is problematic.
To assess the predictive validity of the dimensions identified, a regression analysis is performed, using as its dependent variable a global measure of attitude towards the firm, and as independent variables the firm's scores on the various dimensions.
For example, structured employment interviews have been found to have both high predictive validity (McDaniel, Whetzel, Schmidt & Maurer, 1994; Taylor & Small, 2002; Wiesner & Cronshaw, 1988) and lower levels of ethnic group differences than either unstructured employment interviews or cognitive ability tests (Huffcutt & Roth, 1998).
In other words, individual differences in motivation can modify the strength of the predictive validity of cognitive aptitudes with regard to achievement.
The results of studies using these models appear to provide important parallels to the human situation and should have considerable predictive validity as well as face validity.
This study hypothesized that the WPP is a valid instrument for use within the supported employment environment by establishing: (a) content validity through feedback from expert raters, (b) concurrent validity demonstrated by a positive relationship with job satisfactoriness, (c) construct validity demonstrated by a positive relationship with vocational maturity, and (d) predictive validity demonstrated by a positive relationship with job tenure.
Given that dual-task combinations provide only small increases in the predictive validity of pilot selection batteries (see Damos, 1993, for a summary), the inclusion of 10 such combinations is puzzling.
In addition, multiple regression analysis (MRA) was also conducted on the performance ratings and salary information to assess the AC's predictive validity (a full report of these findings is given in Henderson[16]).
Yet recent studies of one such battery--the McCarron-Dial-confirm earlier research (Fortune & Eldredge, 1982) suggesting that its predictive validity is weak among persons with psychiatric disabilities (Cook & Razzano, 1994).
