Abstract: ABSTRACT A central assumption that is implicit in estimating item parameters in item response theory (IRT) models is the normality of the latent trait distribution, whereas a similar assumption made in categorical confirmatory factor analysis… read more here.

Abstract: When fitting unidimensional item response theory (IRT) models, the population distribution of the latent trait (θ) is often assumed to be normally distributed. However, some psychological theories would suggest a nonnormal θ. For example, some… read more here.

DOI: 10.1177/0146621618789394
Abstract: Questionnaires with uniform-ordered categorical response formats are widely applied in psychology. Muraki proposed a modified graded response model accounting for the items’ uniform response formats by assuming identical threshold parameters defining the category boundaries for… read more here.

DOI: 10.3389/fpsyg.2022.816793
Abstract: This study reveals that strong feelings of altruism were found to be statistically significant in explaining prosocial and pro-environmental behaviors. However, this was not the case for the latent trait biosphere in explaining pro-environmental behavior… read more here.
