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.
