Item Response Modeling of Forced-Choice Questionnaires [PDF]

, 2011
Multidimensional forced-choice formats can significantly reduce the impact of numerous response biases typically associated with rating scales. However, if scored with classical methodology, these questionnaires produce ipsative data, which lead to ...

Item Response Models for Forced-Choice Questionnaires: A Common Framework [PDF]

, 2016
In forced-choice questionnaires, respondents have to make choices between two or more items presented at the same time. Several IRT models have been developed to link respondent choices to underlying psychological attributes, including the recent MUPP ...

Interchangeability between factor analysis, logistic IRT, and normal ogive IRT

Frontiers in Psychology, 2023
In existing studies, it has been argued that factor analysis (FA) is equivalent to item response theory (IRT) and that IRT models that use different functions (i.e., logistic and normal ogive) are also interchangeable. However, these arguments have weak links. The proof of equivalence between FA and normal ogive IRT assumes a normal distribution.
