A regularised latent‐class item response model for detecting measurement non‐invariance in ordinal response scales

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Measurement non‐invariance arises when the psychometric properties of a scale differ across subgroups, undermining the validity of group comparisons. At the item level, this manifests as differential item functioning (DIF), where item responses differ across groups after controlling for the latent trait.

Model fit and parameter uncertainty in amortized variational inference based item response theory

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Amortized variational inference (AVI) has become a popular, computationally efficient alternative to marginal maximum likelihood estimation (MML) for estimating high‐dimensional item response theory models on large datasets. However, currently the AVI framework lacks methods to assess model fit and determine parameter uncertainty.

Measuring Social Capital in Indonesia: An Item Response Theory (IRT) Approach

Jurnal Ekonomi Kuantitatif Terapan
This study assesses social capital in Indonesia using the Item Response Theory (IRT) with the Graded Response Model (GRM), based on data from the 2021 Happiness Level Survey (SPTK) by Statistics Indonesia (BPS), involving 74,684 respondents. Social capital is measured across three dimensions: trust, social participation, and tolerance. Trust is further

An uncomplicated introduction to representational measurement theory

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Measurement in psychology is often associated with psychometrics. Despite the theoretical insights afforded by psychometric methods, they represent only a restricted range of possible measurement approaches in the social sciences. Representational measurement theory (RMT) generalizes the logic of measurement developed in the physical sciences ...

Item Response Theory Model for Understanding Item Non- Response in Ghanaian Surveys [PDF]

, 2014
This paper explores four Item Response Theory (IRT) models to determine the most appropriate forunderstanding item non-response. The selected IRT model was used to identify among five categories of surveyquestions, the most difficult to answer by ...

Reactive Red 195‐loaded halloysite for cotton dyeing and printing: Adsorption, characterisation and comparison with conventional exhaustion dyeing

Coloration Technology, EarlyView.
Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Extending item response theory to online homework

Physical Review Special Topics. Physics Education Research, 2014
Item response theory (IRT) becomes an increasingly important tool when analyzing “big data” gathered from online educational venues. However, the mechanism was originally developed in traditional exam settings, and several of its assumptions are ...
