Using Item Response Theory Models in Scaling Severity Scores in Alcohol Research-A Tutorial. [PDF]

Drug Alcohol Rev
ABSTRACT Introduction Questionnaires are frequently used in the assessment of drug and alcohol dependence. Methods Typically, sum scores are used for aggregation, which come with several underlying assumptions. If untested psychometrically, the reliability and sufficiency of a sum score as a measure of the characteristic of interest remain unclear.

Comparing different trend estimation approaches in country means and standard deviations in international large-scale assessment studies

Large-scale Assessments in Education, 2023
One major aim of international large-scale assessments (ILSA) like PISA is to monitor changes in student performance over time. To accomplish this task, a set of common items (i.e., link items) is repeatedly administered in each assessment.

Reading Comprehension Tests for Children: Test Equating and Specific Age-Interval Reports

Frontiers in Psychology, 2021
Equating is used to directly compare alternate forms of tests. We describe the equating of two alternative forms of a reading comprehension test for Brazilian children (2nd to 5th grade), Form A (n = 427) and Form B (n = 321).

A Note on Equivalent and Nonequivalent Parametrizations of the Two-Parameter Logistic Item Response Model

Information
The two-parameter logistic (2PL) item response model is typically estimated using an unbounded distribution for the trait θ. In this article, alternative specifications of the 2PL models are investigated that consider a bounded or a positively valued θ ...
