In this study the Mantel-Haenszel procedure, widely used in studies for identifying differential item functioning, is proposed as an alternative to the delta-plot method and applied in a test-equating context for flagging common items that behave differentially across cohorts of examinees. The Mantel-Haenszel procedure has the advantage of conditioning on ability when making comparisons of perf...

Estimation of premorbid abilities remains an integral part of neuropsychological evaluations. Several methods of indirect estimation have been suggested in the literature. Many of these methods are based in prediction via linear regression. Unfortunately, linear regression has the well-reported tendency to underpredict high IQ scores and overpredict low IQ scores. This can be shown to be an una...

The current study proposed several variants of simple-structure multidimensional item response theory equating procedures. Four distinct sets data were used to demonstrate feasibility methods for two different designs: a random groups design and common-item nonequivalent design. Findings indicated some notable differences between the unidimensional approaches when exhibited evidence multidimens...

abstract objective: evaluating the usefulness of the triple test score (tts) in breast lesions. materials and methods: medical records of 100 cases were evaluated and tts was calculated based on of physical examination, mammography and fine-needle aspiration cytology findings. the diagnostic value of tts was assessed according to histopathology results. results: of the 23 lesions with score of ...

OBJECTIVE This study investigated the phenomenon known as the healthy user bias by equating hormone therapy (HT) use (past or current) with healthy user status. METHODS Data from the Survey of Midlife in the United States were used to identify the predictors of HT use. The unique Survey of Midlife in the United States data include psychological, demographic, health-related, and behavioral var...
