INTRODUCTION In Europe it is common for outcome measures to be translated for use in other languages. This adaptation may be complicated by culturally specific approaches to certain tasks; for example, bathing. In this context the issue of cross-cultural validity becomes paramount. OBJECTIVE To facilitate the pooling of data in international studies, a project set out to evaluate the cross-cu...
George Engelhard, Emory University Computerized adaptive testing provides an approach to measurement in the social and behavioral sciences which can be used to individualize and tailor a unique set of test items for each individual. Computerized adaptive testing methodsprovide a means for selecting and administering test items that provide the best information about the examinee's location on a...
BACKGROUND The Patient Rated Elbow Evaluation (PREE) was developed as an elbow joint specific measure of pain and disability and validated with classical psychometric methods. More recently, Rasch analysis has contributed new methods for analyzing the clinical measurement properties of self-report outcome measures. The objective of the study was to determine aspects of validity of the PREE usin...
ceiling effect would not be present. Indeed, the ceiling effect strongly suggests that the A&SQ may perform better in samples of amblyopes with acuity much poorer than that of the sample we tested. We agree with Drs. Kelderman, Felius, and Passchier that our modest sample size of 102 amblyopes limits the extent of any interpretation of the Rasch analysis that can be made from our results, and w...
Abstract Due to subjectivity in oral assessment, much concentration has been put on obtaining a satisfactory measure of consistency among raters. However, the process for more might not result valid decisions. One matter that is at core both reliability and validity assessment rater training. Recently, multifaceted Rasch measurement (MFRM) adopted address problem bias inconsistency scoring; how...
In their seminal work on characterizing the manifest probabilities of latent trait models, Cressie and Holland give a theoretically important characterization of the marginal Rasch model. Because their representation of the marginal Rasch model does not involve any latent trait, nor any specific distribution of a latent trait, it opens up the possibility for constructing a Markov chain - Monte ...
The field of Psychometrics routinely grapples with the question of what it means to measure the inherent ability of an organism to perform a given task, and for the last forty years, the field has increasingly relied on probabilistic methods such as the Rasch model for test construction and the analysis of test results. Because the underlying issues of measuring ability apply to human language ...
