Viroporins are ion channels encoded within a virus’s genome, that facilitate a range of devastating infectious diseases such as COVID-19, HIV, and rotavirus. The non-structural protein 4 (NSP4) from rotavirus includes a viroporin domain that disrup

Item response theory (IRT) scaling via a set of items common to two test forms assumes that those item’s parameters are invariant with respect to a linear transformation. Characteristic curve methods rely on this assumption; scale transformations a

This study uses a 3-Parameter Logistic item response theory (IRT) model to develop an 18-item short-form of the Situational Test of Emotion Management (STEM). In a sample of 900 people, the short form showed acceptable reliability (reliability index

Early research on response time modeling assumed that a test taker would show consistent response time behavior, often referred to as working speed, over the course of a test. Such models may be unrealistic for various reasons — a warm-up effect ma

There is a growing interest in the application of item response theory (IRT) models to emotional intelligence (EI) as a means of instrument development. The goal of this study was to create a short form of the Situational Test of Emotional Understand

Latent trait models such as item response theory (IRT) hypothesize a functional relationship between an unobservable, or latent, variable and an observable outcome vari- able. In educational measurement, a discrete item response is usually the observ
