Improving the measurement of QALYs in dementia: developing patient- and carer-reported health state classification systems using Rasch analysis [PDF]

Objectives: Cost-utility analysis is increasingly used to inform resource allocation. This requires a means of valuing health states before and after intervention. Although generic measures are typically used to generate values, these do not perform well

Differential item functioning detection across multiple groups

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Differential item functioning (DIF) can be investigated by estimating item response theory (IRT) parameters separately for different respondent groups, thus allowing for the detection of discrepancies in parameter estimates across groups. However, before comparing the estimates, it is necessary to convert them to a common metric due to the ...

Individual ability on high-stakes test: Choosing cumulative score or rasch for scoring model

Jurnal Penelitian dan Evaluasi Pendidikan
In a test, a method is required to estimate an individual's ability based on their responses. Typically, this is done by summing the correct responses or calculating a cumulative score. An alternative method is the Rasch model.

Latent Poisson count models for action count data from technology‐enhanced assessments

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Recent advances in computerized assessments have enabled the use of innovative item formats (e.g., drag‐and‐drop, scenario‐based), necessitating a flexible model that can capture systematic influence of item types on action counts. In this study, we present a refinement scheme that can explicitly model common features of items and allows ...

Vergleich eines 3D‐gedruckten Hautmodells mit etablierten Methoden zur Lehre der Stanzbiopsie mit Nahtversorgung

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Zusammenfassung Hintergrund Realistische Trainingsmodelle sind essenziell, um Ärztinnen und Ärzte in klinischen Prozeduren zu schulen. In dieser Studie wurde untersucht, ob ein kostengünstiges, selbst generiertes 3D‐gedrucktes Hautmodell Früchten und Schaumstoffmodellen beim Erlernen von Hautstanzen überlegen ist.

The Roles of Vocabulary Size, Word Part Knowledge, and Semantic Transparency in Vocabulary Learning Through the Word Part Technique

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This study investigated the influence of learner‐ and word‐related variables on L2 vocabulary learning through the word part technique (WPT), a morphological mnemonic designed to strengthen form–meaning associations through knowledge of affixes and stems.

The Functional Independence Measure 18-item version can be reported as a unidimensional interval-scaled metric: Internal construct validity revisited

Journal of Rehabilitation Medicine, 2019
Objective: Since the 1990s the Functional Independence Measure (FIM™) was believed to measure 2 different constructs, represented by its motor and cognitive subscales.
