A Tutorial on Interpreting Bifactor Model Scores
International Journal of Testing, 2013This tutorial addresses possible sources of confusion in interpreting trait scores from the bifactor model. The bifactor model may be used when subscores are desired, either for formative feedback on an achievement test or for theoretically different constructs on a psychological test.

A Bifactor Model of Disgust Proneness
Assessment, 2014The current research evaluated a bifactor model for the Disgust Emotion Scale (DES) in three samples: N = 1,318 nonclinical participants, N = 152 clinic-referred patients, and N = 352 nonclinical participants. The primary goals were to (a) use bifactor modeling to examine the latent structure of the DES and in turn (b) evaluate whether the DES should ...

Specific and general facets of hoarding: A bifactor model
Journal of Anxiety Disorders, 2015Whereas it has been suggested that hoarding is a multidimensional construct comprising distinct but interrelated factors (i.e., difficulty discarding, excessive clutter, and excessive acquisition), a high degree of overlap as well as a lack of discriminant validity among these factors and exogenous constructs suggests that a correlated factors approach

Evaluation of the Bifactor Structure of the Dispositional Hope Scale
Journal of Personality Assessment, 2014The Dispositional Hope Scale (DHS; Snyder et al., 1991) is composed of items assessing an individual's perception of his or her agency and pathways. This study examined support for the bifactor structure and relation of the factors in this model with depressive symptoms. It also examined cross-gender measurement invariance for the bifactor model.

A Bifactor Approach to Dimensionality Assessment
2020Bifactor confirmatory factor analysis models and statistical indices computed from them have previously been used to provide evidence for the appropriateness of utilizing a unidimensional interpretation of multidimensional data. However, the ability of bifactor indices to aid in the assessment of subscore strength has not been investigated.

A Comparison of Bifactor and Second-Order Models of Quality of Life
Multivariate Behavioral Research, 2006Bifactor and second-order factor models are two alternative approaches for representing general constructs comprised of several highly related domains. Bifactor and second-order models were compared using a quality of life data set (N = 403). The bifactor model identified three, rather than the hypothesized four, domain specific factors beyond the ...

A Bifactor Model of the Autism Spectrum Disorder Phenotype
Journal of the American Academy of Child & Adolescent Psychiatry, 2019I read with interest the newly published work by Kim et al. describing the covariance structure of parent-reported autism spectrum disorder (ASD) symptoms.1 The authors compared many different latent class, factor analytic, and factor mixture models in a large, clinically referred sample, concluding that the ASD phenotype is best described by three ...

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
