Unifactor Latent Trait Models Applied to Multifactor Tests: Results and Implications.

Reckase, Mark D.

Journal of Educational Statistics, v4 n3 p207-30 Fall 1979

Since all commonly used latent trait models assume a unidimensional test, the applicability of the procedure to obviously multidimensional tests is questionable. This paper presents the results of the application of latent trait, traditional, and factor analyses to a series of actual and hypothetical tests that vary in factoral complexity. (Author/CTM)
