Schizotypy, marijuana, and differential item functioning

Human Psychopharmacology: Clinical and Experimental, 2006
AbstractAt least five studies report elevated schizotypy scores in cannabis users. The current research confirms higher schizotypy scores in regular cannabis users. Nevertheless, further analyses reveal that select items on the brief version of the Schizotypal Personality Questionnaire do not function comparably in current and former users.

A Statistical Test for Differential Item Pair Functioning

Psychometrika, 2015
This paper presents an IRT-based statistical test for differential item functioning (DIF). The test is developed for items conforming to the Rasch (Probabilistic models for some intelligence and attainment tests, The Danish Institute of Educational Research, Copenhagen, 1960) model but we will outline its extension to more complex IRT models.

Differential Item Functioning Analysis Using Rasch Item Information Functions

International Journal of Testing, 2009
Differential item functioning (DIF) analysis is a statistical technique used for ensuring the equity and fairness of educational assessments. This study formulates a new DIF analysis method using the information similarity index (ISI). ISI compares item information functions when data fits the Rasch model.

Measures of shoulder function may differ by dominance of affected shoulder, surgical history, gender, or race. We present a technique for determining whether observed differences in function between groups are due to biased test items or real differences in function.Four hundred patients who were receiving rehabilitation for a variety of shoulder ...

The literature in modern test theory on procedures for identifying items with differential item functioning (DIF) among two groups of persons includes the Mantel–Haenszel (MH) procedure. Generally, it is not recognized explicitly that if there is real DIF in some items which favor one group, then as an artifact of this procedure, artificial DIF that ...
