Using Differential Item Functioning (Dif) Procedures for Investigating the Cross -Cultural Equivalence of Personality Tests
… it had the same number of factors and the same items on each factor. According to the DIF results, the choice of matching variables based on a combination of internal and external measures appeared to have little effect and the iterative purification method was unsuccessful. The DIF results were …

Using differential item functioning analysis to determine differential interpretations of survey questions
The application of Differential Item Functioning (DIF) analysis to noncognitive areas such as psychological and attitudinal measurement is a natural extension of the current research and is the focus of this study. This study uses DIF analyses to examine differential item functioning of Likert …

Investigating the instructional sensitivity of distractors in items exhibiting DIF
… subgroups have comparable ability but different probabilities of correctly responding to an item, the item is said to exhibit differential item functioning (DIF). If the amount of DIF is practically significant, and attributable to features that are irrelevant to the test construct, the …

Structural Equivalence of Vocational Interests Across Culture and Gender: Differential Item Functioning in the Strong Interest Inventory
… and across gender within culture. Gender differences in structure were also compared across countries. Methods developed within the framework of item response theory were applied to test the differential item functioning (DIF) of the items in the inventory. The issue of structural …

An evaluation of item response theory for detecting differential item functioning of examinees' responses to the seventh grade mathematics MEAP test investigating learner characteristics /
… experienced several short comings. Therefore, item response theory was developed in an attempt to explain difference in observed responses and unobserved characteristics such as ability. Statistical techniques were developed to detect differential item functioning (DIF) between two groups. This …

Empirical Evaluation for Gender-Based DIF in an International Assessment: The Case of PIRLS
This study investigated gender differential item functioning (DIF) in the Progress in International Reading Literacy Study (PIRLS) in the 2016 cycle. This is because there is no empirical review of gender DIF in this test. The DIF analyses were conducted within and across three countries which …

Assessing the Differential Functioning of Items and Tests of a Polytomous Employee Attitude Survey
… survey were examined for the presence of differential item functioning (DIF) and differential test functioning (DTF) utilizing Raju, van der Linden, & Fleer's (1995) differential functioning of items and tests (DFIT) framework. Comparisons were made between managers and non-managers on the …

Some issues in item response theory
… the assumption of local independence (LI) in item response theory (IRT) models in the first three chapters, and differential item functioning (DIF) in IRT in the last chapter. A new term ""conditional trivariance"" for three items is defined, which is a measurement of joint local dependence …

HIGH-STAKES TESTS FOR STUDENTS WITH SPECIFIC LEARNING DISABILITIES: DISABILITY-BASED DIFFERENTIAL ITEM FUNCTIONING
… this study was to investigate disability-based differential item functioning (DIF) on a statewide high-stakes mathematics test administered in the Spring of 2003 to all students seeking a high-school diploma in one state in the eastern part of the U.S. Overall performance scores for all students …

Selecting an Optimal Measurement Model and Detecting Differential Item Functioning Using Bayesian Confirmatory Factor Analysis
… constrained parameter estimates in detecting differential item functioning (DIF). I assessed the relative efficiency of WAIC compared to DIC, evaluated analytical WAIC SEs by calculating relative bias, and reported how often WAIC and DIC indicated a preference for each invariance model. I …

Assessing Differential Item Functioning Across Clinical and Community Samples in the Miller Forensic Assessment of Symptoms Test
… symptoms for personal gain. The detection of differential item functioning (DIF) using item response theory methods provides a powerful method of evaluating whether items on a malingering assessment measure function differently in civil versus criminal litigation contexts. The aim of the …

Measurement equivalence of the Comprehensive Personality Scales across cultures: an item response theory approach
Within the item response theory (IRT) framework, this study compared cross-culturally different approaches to the assessment of differential item functioning (DIF) in two personality tests of the Comprehensive Personality Scale (Wang, 2013). A dominance IRT model (SGRM) and an ideal point model …

Investigating Stereotype Threat as a Source of Black/White Differential Item Functioning
… the causes and circumstances surrounding these differences is vital. Drawing from Claude Steele's social-psychological theory on stereotype threat and its role in test score variation, the purpose of this study is to investigate whether stereotype threat is a potential source of differential …

Guidelines for the interpretation of NCDIF as an effect size measure
Several statistics have been proposed to detect Differential Item Functioning (DIF) and quantify its magnitude. However, not all DIF statistics quantify the same population parameters and, therefore, cannot be interpreted interchangeably. We focus on deriving principled guidelines for the …

Differential Item Functioning Analysis of the Herrmann Brain Dominance Instrument
Differential item functioning (DIF) is present when examinees who have the same level of a trait have a different probability of correctly answering a test item intended to measure that trait (Shepard & Averill, 1981). The following study is a DIF analysis of the Herrmann Brain Dominance Instrument …
