The first model estimated was a unidimensional model, in which all items regardless of content or tier were analyzed as if they were part of the same underlying construct.
Using ML estimation, fit indices for a unidimensional GAD-7 were adequate.
Previous Rasch modeling of the PF-10 indicated that the items form a unidimensional, hierarchical continuum with stable item difficulty estimates across diverse patient groups [ 24, 30].
The ODI version 2.1 is a unidimensional questionnaire with high reliability, and well estimates the disability level of back pain without skewing toward the lower or higher levels of disability.
The location of the response criterion (positioned along a unidimensional strength construct of perceptual accuracy) is derived from a participant's estimate as to whether a stimulus constitutes a signal or a noise trial.
For a unidimensional solution it would be expected that, given the difference in estimates are normally distributed, no more than five percent of such tests would be outside the range ± 1.96.
It's a story of revenge: the traditional perfunctory pretext for martial arts - a unidimensional narrative motivation.
The CFA results indicated that a unidimensional model is not sufficient to explain our data structure.
The pain behavior item bank demonstrated good fit to a unidimensional model (Comparative Fit Index = 0.94).
Thus, the following result reduces a coupled fixed point theorem to a unidimensional case.
