Empirical Underidentification with the Bifactor Model: A Case Study [PDF]
Educational and Psychological Measurement, 2018 Bifactor models are commonly used to assess whether psychological and educational constructs underlie a set of measures. We consider empirical underidentification problems that are encountered when fitting particular types of bifactor models to certain types of data sets.

Mol Psychiatry, 2021 AbstractDimensions of irritability and defiant behavior, though correlated within the structure of ODD, convey separable developmental risks through adolescence and adulthood. Irritability predicts depression and anxiety, whereas defiant behavior is a precursor to antisocial outcomes.

Identification and Interpretation of the Completely Oblique Rasch Bifactor Model. [PDF]
PsychometrikaAbstract Bifactor Item Response Theory (IRT) models are the usual option for modeling composite constructs. However, in application, researchers typically must assume that all dimensions of person parameter space are orthogonal. This can result in absurd model interpretations.

Identifiability of Bifactor Models
Statistica Sinica, 2020 The bifactor model and its extensions are multidimensional latent variable models, under which each item measures up to one subdimension on top of the primary dimension(s). Despite their wide applications to educational and psychological assessments, this type of multidimensional latent variable models may suffer from non-identifiability, which can ...
