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.

con·struct va·lid·i·ty

the extent to which a test or procedure appears to measure a higher order, inferred theoretical construct, or trait in contrast to measuring a more limited, specific dimension. See: construct (2).

construct validity

A type of psychometric validity based on scales intended to measure one or more unobservable psychological factors (e.g., distress). Construct validity is usually tested by measuring the correlation in assessments obtained from several scales purported to measure the same construct.

Third, our study lacked methods for assessing the validity of the K-USER-P because we only calculated construct validity. Finally, the number of participants for test-retest analysis is very small.
The NHPT was chosen as the comparison for the construct validity of this new top-down assessment since the NHPT has moderate construct validity with the "gold standard" PPMT and the board and pegs for the standardized NHPT could be constructed in Bangladesh out of wood, according to the original specifications (Mathiowetz et al., 1985) (see Figure 3).
In the current study, construct validity was examined in terms of the correlation between the PMFS and the PFRI.
The results of the present study endowed with strong support for the construct validity of Coping Styles Scale (CSS).
Therefore, we revisited the domain specification of knowledge assets to improve construct validity. To outline some of the major theoretical imperatives of the knowledge-based view, we argued that organizational knowledge assets are an outcome of organizational learning capability accumulated through social interaction among organizational members and between organizational members and external entities.
There was evidence to support the construct validity of the scale.
* What potential modifications could be made to the SAS to improve its construct validity?
The simulator was able to differentiate between novices and experts for a number of parameters in each exercise (construct validity).
Testing the statistical association between a student's status as 'global' or 'analytic' (as directly measured by the BE instrument) and the five discriminating elements constitutes a test of the construct validity of the PEPS which is an instrument for carrying out the DDLSM.
Rather than the factor analysis for construct validity and the typical Cronbach's alpha for interrater reliability, they present measures called limits of agreement (LOA) (Bland & Altman, 1999) for reliability and the one-way analysis of variance (ANOVA) to confirm construct validity.
Furthermore, construct validity of MISTELS has been established for urology trainees and attending urologists.[sup.3] Recently, the American Urological Association's Committee on Laparoscopy, Robotic and New Technology modified the original MISTELS/FLS program into a more urocentric curriculum, the Basic Laparoscopic Urologic Surgery (BLUS) skills curriculum, by replacing the endoloop and extra-corporeal knot tying exercises with a novel clip-applying task.[sup.4] The construct validity of BLUS has been recently demonstrated for the assessment of basic laparoscopic skills of urologists.[sup.4]
