OBJECTIVE To develop a satisfaction measure of activities and participation in the actual environment experienced by patients after chronic stroke using the Rasch measurement model. METHODS A 36-item questionnaire based on the International Classification of Functioning, Disability and Health model and existing scales was developed. The questionnaire was submitted to 101 patients (70% men; me...

Rating scales involving more than two response categories are a popular response format in measurement in education, health and business sciences. Their primary purpose lies in the increase of information and thus measurement precision. For these objectives to be met, the response scale has to provide valid scores with higher numbers reflecting more of the property to be measured. Thus, the res...

The family of Rasch measurement models is a way to make sense of the world. Experience is continuous. But the moment we notice experience, it becomes discrete. We sense the fragrance of flowers. The sensation is continuous. But when we distinguish between flowers—with and without fragrance; strong from weak fragrance, fragrance we like, don’t mind, or dislike, then our observations become discr...

Crowdsourcing requires new strategies to evaluate the workers involved as well as the . Using customer feedback data, we introduce multi-facetted Rasch scaling as an evaluation technique to assess the contributions of workers and products simultaneously within a single coherent measurement framework. Based on a data set of about 250,000 customers who rated nearly 115,000 products, for a total o...

Objective. To assess the multiple mini-interview (MMI) as an admission tool for a satellite campus. Methods. In 2013, the MMI was implemented as part of a new admissions model at the UNC Eshelman School of Pharmacy. From fall 2013 to spring 2015, 73 candidates were interviewed by 15 raters on the satellite campus in Asheville, North Carolina. A many-facet Rasch measurement (MFRM) with three fac...

This paper presents a method for analyzing oral examinations with an extended, many-faceted Rasch model that calibrates medical specialty candidates, protocols, and raters. Significant variance was found among protocol difficulties and rater severities. When candidates' raw scores were compared with calibrated measures corrected for the bias caused by the particular protocols and raters encount...

The notion of that more or less of a physical feature affects in different degrees the users’ impression with regard to an underlying attribute of a product has frequently been applied in affective engineering. However, those attributes exist only as a premise that cannot directly be measured and, therefore, inferences based on their assessment are error-prone. To establish and improve measurem...

Effectively assessing children's academic development can help school professionals make placement decisions and prepare appropriate instructional supports. The KeyMath-3 Diagnostic Assessment (Connolly, 2008) is a widely used assessment of children's mathematical abilities; however, despite much use, the measurement properties of the KeyMath-3 DA have not been examined, aside from the developm...

The main purpose of this research is to computerize GSP chart and Rasch GSP methods. GSP chart and Rasch GSP are effective and useful methods which used for analyzing and evaluating academic achievement. GSP chart provides information for diagnosing the learning status of students and the quality of questions while Rasch GSP provides information for assessing the quality of classes and test qua...
