The study evaluated the comparability of two versions of a certification test: a paperand-pencil test (PPT) and computer-based test (CBT). An effect size measure known as Cohen’s d and differential item functioning (DIF) analyses were used as measures of comparability at the test and item levels, respectively. Results indicated that the effect sizes were small (d < 0.20) and not statistically s...
Item response theory was used to address gender bias in interest measurement. Differential item functioning (DIF) technique, SIBTEST and DIMTEST for dimensionality, were applied to the items of the six General Occupational Theme (GOT) and 25 Basic Interest (BI) scales in the Strong Interest Inventory. A sample of 1860 women and 1105 men was used. The scales were not unidimensional and contain b...
To date, the statistical software designed for assessing differential item functioning (DIF) with Mantel-Haenszel procedures has employed the following statistics: the Mantel-Haenszel chi-square statistic, the generalized Mantel-Haenszel test and the Mantel test. These statistics permit detecting DIF in dichotomous and polytomous items, although they limit the analysis to two groups. On the con...
The present study examines bias factors which might grant a relative advantage to native Israelis over groups of immigrants in a mathematics achievement test administered to fifth grade students. The bias factor analysis process, aided by quantitative and qualitative data gathering methods, comprised three phases: (1) Using a psychometric procedure called DIF (Differential Item Functioning) to ...
The psychometric properties of instruments used to measure self-reported experiences of discrimination in epidemiologic studies are rarely assessed, especially regarding construct validity. The authors used 2000-2001 data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study to examine differential item functioning (DIF) in 2 versions of the Experiences of Discrimination (EOD...
The aims of this paper are to present findings related to differential item functioning (DIF) in the Patient Reported Outcome Measurement Information System (PROMIS) depression item bank, and to discuss potential threats to the validity of results from studies of DIF. The 32 depression items studied were modified from several widely used instruments. DIF analyses of gender, age and education we...
BACKGROUND Mastery refers to the degree to which people perceive that they can control factors that influence their life situation, and has been found important for people's quality of life and well-being. It is thus essential to be able to measure mastery in a valid and reliable way. AIM This study aimed at using the Rasch measurement model to investigate the psychometric properties of a Swe...
Abstract: Although the Moral Growth Mindset (MGM) Measure was tested and validated in general, whether it measures MGM consistently across people with different political perspectives associated moral foundations, has not been tested. We examined measurement invariance (MI) differential item functioning (DIF) affiliations to test functioned consistently. also relationship between MGM, affiliati...
