Rasch Analysis Of Relational Well-Being Within The National Survey Of Adoptive Parents Of 2007: A Comparison Of Multidimensional, Consecutive, And Unidimensional Approaches To Measure Construction, Michael A. Furno

Electronic Theses and Dissertations

A unidimensional Rasch approach was used to explore whether the data collected through the National Survey of Adoptive Parents of 2007 (NSAP) for the well-being items represented a single latent construct and to establish a base model for comparison. A consecutive approach was then used as an exploratory tool to draw out potential multiple dimensions. Finally, multidimensional item response theory (MIRT) was used to confirm the results of the consecutive approach findings while comparing with the unidimensional baseline. Items within the survey were evaluated for scale function as well as invariance.

The comparison of three approaches (unidimensional, combined consecutive, and …
