Application of Alternative IRT models to IRT Assumption Violation
The purpose of this study is to investigate the most appropriate alternative IRT parameter estimation models among bi-factor model, testlet based model, and second-order IRT model when the IRT assumptions are not met. A simulation study was conducted to compare the alternative IRT parameter estimation models when the assumptions are unsatisfied. First,

A Bayesian Beta-Mixture Model for Nonparametric IRT (BBM-IRT)
Item response models typically assume that the item characteristic (step) curves follow a logistic or normal cumulative distribution function, which are strictly monotone functions of person test ability. Such assumptions can be overly-restrictive for real item response data.

Assessing the Impact of Characteristics of the Test, Common-items, and Examinees on the Preservation of Equity Properties in Mixed-format Test Equating [PDF]
Preservation of equity properties was examined using four equating methods - IRT True Score, IRT Observed Score, Frequency Estimation, and Chained Equipercentile - in a mixed-format test under a common-item nonequivalent groups (CINEG) design.

Pancreatitis-Associated Protein in Neonatal Screening for Cystic Fibrosis: Strengths and Weaknesses
There are currently four countries and one local region in Europe that use PAP in their newborn screening programme. The first country to employ PAP at a national level was the Netherlands, which started using IRT/PAP/DNA/EGA in 2011. Germany followed in

Psychometric properties of the general conspiracy belief scale using item response theory
Evaluation of the psychometric properties of conspiracy theory belief instruments has been dominated by classical approaches with limitations, especially in dependence on sample size and inaccuracies in item-level analysis.
