The application of Multifaceted Rasch Measurement (MFRM) in rating test takers’ oral language proficiency has been investigated in some previous studies (e.g., Winke, Gass, & Myford, 2012). However, little research so far has ever documented the effect of test takers’ genders on their oral performances and few studies have investigated the relationship between the impact of raters’ gender on th...

BACKGROUND Early childhood development is a multifaceted construct encompassing physical, social, emotional and intellectual competencies. The Early Development Instrument (EDI) is a population-level measure of five domains of early childhood development on which extensive psychometric testing has been conducted using traditional methods. This study builds on previous psychometric analysis by p...

Innovative applications of Rasch analysis can lead to solutions for traditional measurement problems and can produce new assessment applications in occupational therapy and health care practice. First, Rasch analysis is a mechanism that translates scores across similar functional ability assessments, thus enabling the comparison of functional ability outcomes measured by different instruments. ...

The Rasch measurement model for developing and revising career assessment tools has many advantages over traditional test development methods. To better understand this method, the current study met its two purposes (a) to illustrate how the Rasch measurement model can aid vocational psychology researchers in increased precision and accuracy in assessment; and (b) to examine the psychometric an...

Abstract Quantitative consumer and marketing research is looking back on an era of construct operationalization predominantly based on classical test theory as a technical framework of scale development. Rasch measurement theory provides an alternative framework of measurement. Previous studies demonstrated the potential of Rasch measurement for marketing research from a theoretical viewpoint, ...

Aviation history provides an apt metaphor for the state of Rasch measurement practice, and its potential future. Flying was initially widely believed to be nothing but a spectacular and dangerous fad. Few saw in it any potential for the huge industry that it is today. The current state of Rasch measurement practice is quite akin to daredevil barnstorming in that the field is focused on isolated...

BACKGROUND Measurement scales seeking to quantify latent traits like attitudes, are often developed using traditional psychometric approaches. Application of the Rasch unidimensional measurement model may complement or replace these techniques, as the model can be used to construct scales and check their psychometric properties. If data fit the model, then a scale with invariant measurement pro...

Necessary and sufficient relations between measurement objectivity and psychometric models for data in more than two categories are reviewed and extended. Rasch (1960, 1961) and others prove the sufficiency of Rasch models for objectivity. Douglas and Wright (1986) derive the model necessary for objectivity for data in two categories. Rasch (1968) outlines a proof of the model necessary for obs...

This chapter provides an introductory overview of many-facet Rasch measurement (MFRM). Broadly speaking, MFRM refers to a class of measurement models that extend the basic Rasch model by incorporating more variables (or facets) than the two that are typically included in a test (i.e., examinees and items), such as raters, scoring criteria, and tasks. Throughout the chapter, a sample of rating d...
