Differential Item Functioning Detection with Logistic Regression
résumé – Détection du fonctionnement différentiel d’items par régression logistique La régression logistique a été utilisée comme une méthode d’identification du DIF dans différents contextes. Certaines études ont montré que cette procédure peut être affectée par des variables comme le ratio des tailles entre groupes, la taille de l’échantillon, et qu’elle semble liée avec les gammes de difficu...
متن کاملMultiple Ways to Detect Differential Item Functioning in SAS
Differential item functioning (DIF), as an assessment tool, has been widely used in quantitative psychology, educational measurement, business management, and insurance and healthcare industries. The purpose of DIF analyses is to detect response differences of items in questionnaires, rating scales, or tests across different subgroups (e.g., gender), while controlling for ability level. There a...
متن کاملUse of multilevel logistic regression to identify the causes of differential item functioning.
Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning...
متن کاملUsing Multiple-Variable Matching to Identify EFL Ecological Sources of Differential Item Functioning
Context is a vague notion with numerous building blocks making language test scores inferences quite convoluted. This study has made use of a model of item responding that has striven to theorize the contextual infrastructure of differential item functioning (DIF) research and help specify the sources of DIF. Two steps were taken in this research: first, to identify DIF by gender grouping via l...
متن کاملExtension of an iterative hybrid ordinal logistic regression/item response theory approach to detect and account for differential item functioning in longitudinal data.
Many constructs are measured using multi-item data collection instruments. Differential item functioning (DIF) occurs when construct-irrelevant covariates interfere with the relationship between construct levels and item responses. DIF assessment is an active area of research, and several techniques are available to identify and account for DIF in cross-sectional settings. Many studies include ...
