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

[kon′strəkt]
validity of a test or a measurement tool that is established by demonstrating its ability to identify or measure the variables or constructs that it proposes to identify or measure. The judgment is based on the accumulation of correlations from numerous studies using the instrument being evaluated. See also validity.

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.

construct validity,

n the degree to which an experimentally-determined definition matches the theoretical definition.

Overall, there is evidence that the domains of the ACE correlated significantly with the instruments with which they were expected to correlate, providing evidence for convergent construct validity.
Consistency of the observed relationships with the hypothesized relationships in the upper part of the nomological network provides evidence for the construct validity of [O.
Demonstrating the existence of a nomological network of relationships with other variables through criterion-related validity, assessing two groups who would be expected to differ on the measure, and the demonstrating discriminant and convergent validity using a method such as the multitrait-multimethod matrix developed by Campbell and Fiske (MTMM, 1959) would provide further evidence of the construct validity of the new measure.
After establishing the factor structure of the EHS in Study 1 and providing experimental evidence for the sensitivity of the EHS to detect differences between the cognitive saliency of a meaningful experience relative to a neutral experience in Study 2, the purpose of Study 3 was to (a) replicate the factor structure of the EHS found in Study 1 and (b) examine additional evidence of construct validity for the EHS subscales to build upon the results of Study 2.
Since the Purdue Pegboard Test is considered to have good construct validity (Yancosek & Howell, 2009), and the NHPT has been found to have a moderate correlation to the Purdue Pegboard Test (Mathiowetz et al.

Construct validity is defined as the degree of accuracy to which a measure captures a theoretical concept corresponding to the real world.
Beginning construct validity was established by comparing groups in three designated clinical skills and comparing their scores using t-tests to assess if there were any significant differences between the students who had and those who had not experienced performance accomplishments (i.

12,15,19) The construct validity of the Persian version of the OKS was calculated by correlation between summed scores of the Persian OKS with the mean scores of different domains of the Persian SF-36 amongst our participants.
In the case of functional status or symptoms there is no gold standard and therefore construct validity must be established in its place (Amadio 2001).
