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.

Estimating the Importance of Differential Item Functioning

Journal of Educational and Behavioral Statistics, 1995
Several methods have been proposed to detect differential item functioning (DIF), an item response pattern in which members of different demographic groups have different conditional probabilities of answering a test item correctly, given the same level of ability. In this article, the mixture index of fit, proposed by Rudas, Clogg, and Lindsay (1994)

5 Differential Item Functioning and Item Bias

2006
Publisher Summary This chapter presents a description of many of the commonly employed methods in the detection of item bias. Because much of the statistical detection of item bias makes the use of differential item functioning (DIF) procedures, the majority of this chapter focuses on the description of statistical methods for the analysis of DIF ...

Multiple-Group Noncompensatory Differential Item Functioning in Raju's Differential Functioning of Items and Tests

International Journal of Testing, 2015
Raju, van der Linden, and Fleer (1995) introduced a framework for differential functioning of items and tests (DFIT) for unidimensional dichotomous models. Since then, DFIT has been shown to be a quite versatile framework as it can handle polytomous as well as multidimensional models both at the item and test levels.

Screening Test Items for Differential Item Functioning

Journal of Educational and Behavioral Statistics, 2014
A method for medical screening is adapted to differential item functioning (DIF). Its essential elements are explicit declarations of the level of DIF that is acceptable and of the loss function that quantifies the consequences of the two kinds of inappropriate classification of an item.

Assessment of differential item functioning.

Journal of applied measurement, 2009
This study addresses several important issues in assessment of differential item functioning (DIF). It starts with the definition of DIF, effectiveness of using item fit statistics to detect DIF, and linear modeling of DIF in dichotomous items, polytomous items, facets, and testlet-based items.

Ramsay-Curve Differential Item Functioning

Applied Psychological Measurement, 2011
Differential item functioning (DIF) occurs when an item on a test, questionnaire, or interview has different measurement properties for one group of people versus another, irrespective of true group-mean differences on the constructs being measured. This article is focused on item response theory based likelihood ratio testing for DIF (IRT-LR or IRT ...

Differential Item Functioning in Diagnostic Classification Models

2019
Assessment of differential item functioning (DIF) in diagnostic classification models (DCMs) has begun to attract research attention. In previous studies, authors found that DIF detection in DCMs appeared to be very powerful even when most or all the items on the studied test had DIF and no scale purification was necessary.
