Enhancing generalizability theory with mixed‐effects models for heteroscedasticity in psychological measurement: A theoretical introduction with an application from EEG data

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 661-686, November 2026.
Abstract Generalizability theory (G‐theory) defines a statistical framework for assessing measurement reliability by decomposing observed variance into meaningful components attributable to persons, facets, and error. Classic G‐theory assumes homoscedastic residual variances across measurement conditions, an assumption that is often violated in ...

Asymptotic standard errors for reliability coefficients in item response theory

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 702-719, November 2026.
Abstract In a recent review, Liu et al. (Psychological Methods, 2025b) classified reliability coefficients into two types: classical test theory (CTT) reliability and proportional reduction in mean squared error (PRMSE). This article focuses on quantifying the sampling variability of these coefficients under item response theory (IRT) models.

Bias and precision in true‐score estimation

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 720-743, November 2026.
Abstract We discuss two approaches to estimating the true score from classical test theory, each with a corresponding measure of uncertainty due to measurement error: the classical method with the standard error of measurement (SEM) and Kelley's method with the standard error of estimation (SEE).

ESTIMASI MAKSIMUM LIKELIHOOD PADA ITEM RESPONSE THEORY (IRT) DAN APLIKASINYA PADA COMPUTERIZED ADAPTIVE TESTS (CAT)

, 2011
In this thesis, it wil be discussed how to estimate paramaters on Item Response Theory (IRT). There are three models of logistics on IRT, One Parameter Logistics Model (1-PL), Two Parameter Logistics Model (2-PL), and Three Parameter Logistics Model (3 ...

Mokken Scale Analysis in R [PDF]

Mokken scale analysis (MSA) is a scaling procedure for both dichotomous and polytomous items. It consists of an item selection algorithm to partition a set of items into Mokken scales and several methods to check the assumptions of two nonparametric item

A taxonomy of reliability indices for cluster‐level constructs measured by multiple individual‐level indicators

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 513-546, November 2026.
Abstract Generalizability theory (GT) provides a variety of intraclass correlation coefficients (ICCs) to quantify reliability across different conditions of measurement—for example, scale and interrater reliability quantify generalization across items and raters, respectively.

Long‐Term Disease Control Following Completion of Cladribine Treatment in Multiple Sclerosis: Extended Follow‐Up of the CladStop Cohort

European Journal of Neurology, Volume 33, Issue 11, November 2026.
After completion of the standard two‐year cladribine regimen, many patients with relapsing multiple sclerosis maintained sustained disease control during extended real‐world follow‐up. Relapse activity and disability progression remained low, although about 40% of patients initiated a subsequent disease‐modifying therapy during follow‐up.

Analysis of Programming Test by Item Response Theory [PDF]

Item Response Theory (IRT) is a method to analyze test and test items with assumpitions on the mathematical relationship between abilities and item responses. IRT is used for developing and refining test items in many fields of education.

Economic Insecurity, Greenlash and the Demand for Climate Policies in Europe

Kyklos, Volume 79, Issue 4, Page 1010-1027, November 2026.
ABSTRACT We study how perceived economic insecurity predicts people's support for climate policies across European regions. By developing a new political economy model and using a dataset with 17 European countries, we show that larger perceived economic insecurity is robustly associated with lower support for climate policies involving higher taxes on
