Towards standardization of measuring anxiety and depression: Differential item functioning for language and Dutch reference values of PROMIS item banks

PLoS ONE, 2022
Introduction The outcomes anxiety and depression are measured frequently by healthcare providers to assess the impact of a disease, but with numerous instruments. PROMIS item banks provide an opportunity for standardized measurement.

Gender differential item functioning on the Kentucky Inventory of Mindfulness Skills instrument using logistic regression

REID (Research and Evaluation in Education), 2022
The item differential function (DIF) describes a situation in which testees of similar ability but from different demographic groups have varying chances of achieving the same result.

A Comparison of Linking Methods for Two Groups for the Two-Parameter Logistic Item Response Model in the Presence and Absence of Random Differential Item Functioning

Foundations, 2021
This article investigates the comparison of two groups based on the two-parameter logistic item response model. It is assumed that there is random differential item functioning in item difficulties and item discriminations.

Detecting Differential Item Functioning in 2PL Multistage Assessments

Psych, 2023
The detection of differential item functioning is crucial for the psychometric evaluation of multistage tests. This paper discusses five approaches presented in the literature: logistic regression, SIBTEST, analytical score-based tests, bootstrap score ...

Differential item functioning and ad hoc interpretations [PDF]

Teaching English Language, 2010
A plethora of research studies has focused on Differential Item Functioning. Despite the diversity of DIF detection techniques offered, little research has been done on the interpretation of DIF results.

Evaluating the Magnitude of Differential Item Functioning in Polytomous Items [PDF]

Journal of Educational and Behavioral Statistics, 1994
Several recent studies have investigated the application of statistical inference procedures to the analysis of differential item functioning (DIF) in polytomous test items that are scored on an ordinal scale. Mantel’s extension of the Mantel-Haenszel test is one of several hypothesis-testing methods for this purpose.

The effect of missing data and imputation on the detection of bias in cognitive testing using differential item functioning methods

BMC Medical Research Methodology, 2022
Background Item response theory (IRT) methods for addressing differential item functioning (DIF) can detect group differences in responses to individual items (e.g., bias).

Improving the assessment of measurement invariance: Using regularization to select anchor items and identify differential item functioning.

Psychological methods, 2020
A common challenge in the behavioral sciences is evaluating measurement invariance, or whether the measurement properties of a scale are consistent for individuals from different groups.

How to Perform Three-Step Latent Class Analysis in the Presence of Measurement Non-Invariance or Differential Item Functioning

Structural Equation Modeling: A Multidisciplinary Journal, 2020
The practice of latent class (LC) modeling using a bias-adjusted three-step approach has become widely popular. However, the current three-step approach has one important drawback – its key assumption of conditional independence between external ...
