Differential item functioning procedures for polytomous items when examinee sample sizes are small
As part of test score validity, differential item functioning (DIF) is a quantitative characteristic used to evaluate potential item bias. In applications where a small number of examinees take a test, statistical power of DIF detection methods may be affected. Researchers have proposed modifications to DIF detection methods to account for small focal group examinee sizes for the case when item...
متن کاملAssessing Differential Item Functioning on the Test of Relational Reasoning
The test of relational reasoning (TORR) is designed to assess the ability to identify complex patterns within visuospatial stimuli. The TORR is designed for use in school and university settings, and therefore, its measurement invariance across diverse groups is critical. In this investigation, a large sample, representative of a major university on key demographic variables, was collected, and...
متن کاملLatent variable mixture models to test for differential item functioning: a population-based analysis
BACKGROUND Comparisons of population health status using self-report measures such as the SF-36 rest on the assumption that the measured items have a common interpretation across sub-groups. However, self-report measures may be sensitive to differential item functioning (DIF), which occurs when sub-groups with the same underlying health status have a different probability of item response. This...

15 صفحه اولMeasuring differential item and test functioning across academic disciplines
Differential item functioning (DIF) is when a test item favors or hinders a characteristic exhibited by group members of a test-taking population. DIF analyses are statistical procedures used to determine to what extent the content of an item affects the item endorsement of sub-groups of test-takers. If DIF is found for many items on the test, the final test scores do not represent the same mea...
