A mixed-effects item response theory model that allows for three-level multivariate ordinal outcomes and accommodates multiple random subject effects is proposed for analysis of multivariate ordinal outcomes in longitudinal studies. This model allows for the estimation of different item factor loadings (item discrimination parameters) for the multiple outcomes. The covariates in the model do no...

This paper describes the development and validation of the Health Literate Primary Car...

BACKGROUND The Quantitative Myasthenia Gravis Score and the Myasthenia Gravis Composite are two commonly used outcome measures in Myasthenia Gravis. So far, their measurement properties have not been compared, so we aimed to study their psychometric properties using the Rasch model. METHODS 251 patients with stable myasthenia gravis were assessed with both scales, and 211 patients returned fo...

There is a broad literature in multiple-choice test development, both terms of item-writing guidelines, and psychometric functionality as measurement tool. However, most the published concerns testing context expert-designed high-stakes standardized assessments, with little attention being paid to use technique within non-expert instructor-created classroom examinations. In this work, we presen...

This paper illustrates a sequential item development process to create a new self-report instrument of depression refined with Rasch analysis from a larger pool of potential diagnostic items elicited through a consensus approach by clinical experts according to the latest edition of the Diagnostic and Statistical Manual of Mental Disorders criteria for major depression. A 51-item pool was admin...
