IRT linking methods for the bifactor model
2018<p>For unidimensional item response theory (UIRT) models, three linking methods, which are the separate, concurrent, and fixed parameter calibration methods, have been developed and widely used in applications such as vertical scaling, differential item functioning, computerized adaptive testing (CAT), and equating. By contrast, even though a few

Recovering bifactor models: A comparison of seven methods.
Psychological Methods, 2020The last decade has witnessed a resurgence of interest in exploratory bifactor analysis models and the concomitant development of new methods to estimate these models. Understandably, due to the rapid pace of developments in this area, existing Monte Carlo comparisons of bifactor analysis have not included the newest methods.

A Mixture Group Bifactor Model for Binary Responses
Structural Equation Modeling: A Multidisciplinary Journal, 2014The presence of nuisance dimensionality is a potential threat to the accuracy of results for tests calibrated using a measurement model such as a factor analytic model or an item response theory model. This article describes a mixture group bifactor model to account for the nuisance dimensionality due to a testlet structure as well as the ...

Journal of Abnormal Child Psychology, 2020
My commentary is organized into four sections. First, I summarize the reasons for the original interest in fitting symmetric bifactor models to ADHD data. Second, I summarize the concerns that Burns and colleagues raised with respect to fitting symmetric bifactor models to ADHD item-level data and describe their recommended alternative approach. Third,

A bifactor model of meanness, coldheartedness, callousness, and sadism
Personality and Individual Differences, 2019Abstract Although callous/unemotional or mean psychopathic traits overlap with sadism, there may be specific aspects differentiating sadism from this component of psychopathy. The factor structure of eight scales that assess sadism or the meanness component of psychopathy was examined using confirmatory factor analysis in two independent samples: an ...

A Bifactor Model of the Straightforward Attentional Control Scale
Journal of Psychopathology and Behavioral Assessment, 2019Prior studies suggest that the Attentional Control Scale (ACS) consists of two correlated factors. These models do not include a general factor, though this is assumed often in theory and practice. Using an adult North American sample collected through Amazon Mechanical Turk (N = 419), we examined a revised version of the ACS with positive keying of ...

Culture and the Structure of Affect: A Bifactor Modeling Approach
Journal of Happiness Studies, 2015This paper tested the impact of culture on the basic structure of affect. It examined positive affect and negative affect at three levels of activation in the U.S. and China. It used a well-suited tool, the bifactor model, to separate the common variance shared by all types of affect from the variance unique to each.
