Rasch analysis of the evaluation in Ayres sensory integration (EASI)
… on the EASI. In this dissertation, I used Rasch analysis to evaluate data with 19 of the 21 tests. The Rasch model is a latent-trait psychometric model that (1) transforms ordinal-level data to interval-level data and (2) allows users to assess evidence for construct validity …

A Rasch Analysis of the Mental Health and Recovery Measure: Reliability and Validity
… scale developed based on a grounded theory analysis (Young & Ensing, 1999) of information from individuals with severe and persistent mental illness regarding their understanding of the “lived experience” of recovery. The MHRM has previously been found (Bullock, 2005; Young, Ensing, & …

Accuracy of Global Fit Indices as Indictors of Multidimensionality in Multidimensional Rasch Analysis
Most research on confirmatory factor analysis using global fit indices (AIC, BIC, AICc, and CAIC) has been in the structural equation modeling framework. Little research has been done concerning application of these indices to item response models, especially within the framework of …

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
<p>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 …

Development of a Brief Screening Measure for Depression and Problem Drinking
… several analytic techniques. Exploratory factor analysis identified three factors indicating the measure contained depression (PHQ-4), alcohol use (AUDIT-C), and impulsivity factors. Rasch analysis resulted in identifying 15-item measure as multidimensional. Further Rasch analysis showed the …

The measurement properties of the inventory of reading occupations: An assessment tool of children's reading occupations
… was comprised of two studies. The quantitative Rasch analysis of the IRO included administration of the tool to 192 children from kindergarten to third grade from five different states. Results of the Rasch analysis showed the over-all good fit of the IRO in the unidimensionality model of Rasch …

Toward a Domain Theory of Fluent Oral Reading with Expression
… This order, as determined by a many-facets Rasch analysis, is (a) phrasing, (b) smoothness, (c) rate, (d) expression, and (e) confidence. When accuracy is used in the same Rasch analysis, it was found to be easier than phrasing, showing that the method used to select texts easy enough for …

Development of a Measure Assessing Knowledge and Use of Internal Punctuation to Signal Syntactic Relationships
… of syntactical structures (phrases and clauses). Rasch analysis found the measure as a whole possibly supporting a second dimension; therefore, the measure was analyzed as two scales: (a) a 34-item test of internal punctuation use and (b) a 16-item identification of syntactic structures. Both …
