This paper illustrates first how estimated Structural Equation Modeling (SEM) measurement error variances are actually estimates of score reliabilities. The major advantage of SEM over other analytic methods is that it accounts for measurement error. Score reliabilities are estimated as part of structural modeling, so that structural models test…

In judgmental standard setting experiments, it may be difficult to specify subjective probabilities that adequately take the properties of the items into account. As a result, these probabilities are not consistent with each other in the sense that they do not refer to the same borderline level of performance. Methods to check standard setting…

The purpose of this study was to estimate the extent to which recording variability among standardized patients (SPs) has an impact on classification consistency with data sets simulated to reflect performances on a large-scale clinical skills examination. SPs are laypersons trained to portray patients in clinical encounters (cases) and to record…

Given the potential value of reliability generalization (RG) studies in the development of cumulative psychometric knowledge, the purpose of this paper is to provide a tutorial on how to conduct such studies and to serve as a guide for researchers wishing to use this methodology. After some brief comments on classical test theory, the paper…

Test validity refers to the degree to which the inferences based on test scores are meaningful, useful, and appropriate. Thus, test validity is a characteristic of a test when it is administered to a particular population. This article introduces the modern concepts of validity advanced by S. Messick (1989, 1996, 1996). Traditionally, the means of…

The results of this study showed that the relative usefulness of the three forms of the Mini Mult, a 71-item form of the MMPI, were not encouraging. (JC)

While the PPVT is widely used with both typical (i.e., regular classroom students) and atypical (i.e., special class students such as retardates or cerebral palsied) children, there is a dearth of reliability data available for the typical group. (Authors)

Results indicate that scoring tests by the self-scoring method can result in a higher split half reliability than tests scored by the traditional right-wrong method. (Authors)
