Validity Assessment
Flashcards do conjunto (15)
- 1ValidityThe extent to which an instrument
reflects the concept being examined. - 2Face validityItems appear to reflect the concept
they are supposed to test,
(weakest form of validity). - 3Content validityItems making up an instrument
adequately represent the concept
as rated by content experts. - 4Criterion-related validityOutcomes of an instrument compare favorably to those from an established gold-standard criterion test.
- 5Concurrent validityEstablishes validity of a target test
when two measures
(target test and gold-standard test)
taken at the same time have similar results. - 6Predictive validityEstablishes validity of a target test when the target test predicts a future criterion score on a gold-standard test.
- 7Construct validityThe ability of an instrument to
differentiate among similar concepts. - 8Contrasting group validityA type of construct validity in which groups known to be high or low on a characteristic are used to measure that construct.
- 9Convergent validityA type of construct validity in which measurements that should be related are related when two tests are used.
(If scores converge, the same construct is being measured). - 10Divergent validityA type of construct validity in which there are low or no correlations between scores on instruments measuring different characteristics by similar methods.
- 11FactorA combination or cluster of related observed variables that represents a specific underlying dimension of a construct.
- 12Factor AnalysisStatistical procedure to determine if a set of items measure an underlying latent variable. Used to evaluate a questionnaire to determine if it is unidimensional or multidimensional.
- 13Latent variableSomething that cannot
be directly measured. - 14Exploratory Factor AnalysisFactor analysis performed on a set
of items to determine underlying dimensions. Based on multiple
general linear regression. - 15Confirmatory Factor AnalysisFactor analysis to determine if an underlying structure is consistent
with theory or previous research. Performed with structural equation modeling.
