Abstract Given the significance of test fairness, this study aimed to investigate a reading comprehension for evidence differential item functioning (DIF) based on English as Foreign Language (EFL) learners’ gender and their mode learning (conventional vs. distance learning). To end, 514 EFL learners were asked take 30-item multiple-choice test. After establishing unidimensionality local indepe...

OBJECTIVE When comparing outcomes of the Functional Independence Measure (FIM ) between patient groups, item characteristics of the FIM should be consistent across groups. The purpose of this study was to compare item difficulty of the FIM in 3 patient groups with neurological disorders. SUBJECTS Patients with stroke (n=295), multiple sclerosis (n=150), and traumatic brain injury (n=88). ME...

BACKGROUND The International Classification of Functioning, Disability and Health (ICF) proposes three main health outcomes, Impairment (I), Activity Limitation (A) and Participation Restriction (P), but good measures of these constructs are needed The aim of this study was to use both Classical Test Theory (CTT) and Item Response Theory (IRT) methods to carry out an item analysis to improve me...

OBJECTIVE The main aim of this study was to provide evidence of the broad employability of the NEQ with patients of different gender and age with cancer in different phases of the disease and care process, using an Item Response Theory (IRT) approach and investigating Differential Item Functioning (DIF). METHODS The NEQ was completed by 762 patients visiting, consecutively, outpatient clinics...

Although a substantial amount of research has been conducted on differential item functioning in testing, studies have focused on detecting differential item functioning rather than on explaining how or why it may occur. Some recent work has explored sources of differential functioning using explanatory and multilevel item response models. This study uses hierarchical generalized linear modelin...

The purpose of this article is to introduce the methods used and challenges confronted by the authors of this two-part series of articles describing the results of analyses of measurement equivalence of the short form scales from the Patient Reported Outcomes Measurement Information System (PROMIS). Qualitative and quantitative approaches used to examine differential item functioning (DIF) are ...

Abstract Numeracy—the ability to understand and use numeric information—is linked good decision-making. Several problems exist with current numeracy measures, however. Depending on the participant sample, some existing measures are too easy or hard; also, established often contain items well-known participants. The article aimed develop new understanding (NUMs) including a 1-item (1-NUM), 4-ite...

Uniform diagnostic criteria for the night eating syndrome (NES), a disorder characterized by a delay in the circadian pattern of eating, have not been established. Proposed criteria for NES were evaluated using item response theory (IRT) analysis. Six studies yielded 1,481 Night Eating Questionnaires which were coded to reflect the presence/absence of five night eating symptoms. Symptoms were e...

Likert scales are routinely used in educational and psychological research as measures of constructs of interest. If sound scale development procedures are followed, the resulting scale can reliably and validly measure a construct. However, if a given scale is used to make comparisons among different populations of respondents (e.g., cultures; Riordan & Vandenberg, 1994), over time in longitudi...
