The reliability and validity of the six traits comprising High Potential Trait Indicator (HPTi) were evaluated using Rasch analysis. Focus was designated to unidimensionality local independence each subscale; fit model; person separation; differential item functioning (DIF). Secondary data, obtained from intellectual property rights holder Thomas International, used for analysis with a sample 1...

BACKGROUND Perception-based Likert scale are commonly used to assess household food insecurity. The aim of this study was to evaluate the psychometric properties and external construct validity of the 9-item Food Access Survey Tool (FAST) in a population-based randomized controlled trial. METHODS Participating women (n = 11,992) were asked to recall the frequencies of nine food insecurity exp...

Accurate assessment of attitudes about intimate partner violence is important for evaluation of prevention and early intervention programs. Assessment of attitudes about cross-gender interactions is particularly susceptible to bias because it requires specifying the gender of the perpetrator and the victim. As it is likely that respondents will tend to identify with the same-gender actor, items...

BACKGROUND The aim of this study was to test the internal validity of the total Center for Epidemiologic Studies-Depression (CES-D) scale using Rasch analysis in a rheumatoid arthritis (RA) population. METHODS CES-D was administered to 157 patients with RA over three time points within a 12 month period. Rasch analysis was applied using RUMM2020 software to assess the overall fit of the model...

Evaluating measurement equivalence (also known as differential item functioning (DIF)) is an important part of the process of validating psychometric questionnaires. This study aimed at evaluating the multiple indicators multiple causes (MIMIC) model for DIF detection when latent construct distribution is nonnormal and the focal group sample size is small. In this simulation-based study, Type I...

Islamic financial literacy is an emerging term which increasingly used in research and policy. Though a study this area growing, there lack of accepted method to measure literacy. This aims develop valid reliable instrument access among MUM (Muslim Urban Millennial) generations using Rasch analysis. A comprehensive literature review qualitative were initially performed identify the construct to...

As a result of the COVID-19 pandemic situation, educators in Malaysia have resorted to use learning medium Google Classroom as an alternative existing online teaching methods. Past studies focused on direct and indirect factors towards intention public institutes higher learning. This study therefore aimed identify level tendency acceptance items Classroom-assisted among Form Six economics stud...

The detection of differential item functioning (DIF) is an essential step in increasing the validity of a test for all groups. The item response theory (IRT) model comparison approach has been shown to be the most flexible and powerful method for DIF detection; however, it is computationally-intensive, requiring many model-refittings. The Wald test, originally employed by Lord for DIF detection...

BACKGROUND Little is known about cross-language measurement equivalence of the job content questionnaire (JCQ) PURPOSE: The purposes of this study were to assess the extent of cross-language differential item functioning (DIF) of the 27 JCQ items in six languages (French, Dutch, Belgian-French, Belgian-Dutch (Flemish), Italian, and Swedish) from six European research centers and to test whether...

The detection of differential item functioning is crucial for the psychometric evaluation multistage tests. This paper discusses five approaches presented in literature: logistic regression, SIBTEST, analytical score-based tests, bootstrap and permutation First, using an simulation study inspired by a real-life large-scale educational assessment, we compare with respect to their type I error ra...
