In this study, psychometric properties of the test of the three-mathematical minds (M3) were investigated. The M3 test was developed based on a multidimensional conception of giftedness to identify mathematically talented students. Participants included 291 middle-school students. Data analysis indicated that the M3 had a 0.73 coefficient as a…

This paper proposes a method of transforming item p-values (the proportion answering a test item correctly) to what are termed "delta" values. First used by Conrad in l948, deltas are routine statistics computed in all analyses at Educational Testing Service. Using this approach one would conclude no test bias if differences in resulting deltas…

This program provides comprehensive item statistics and response analyses for tests, questionnaires, and rating scales. (RC)

At the Medical College of Wisconsin, a procedure was developed to allow computerized grading and grade reporting of laboratory practical examinations in the Clinical Human Anatomy course. At the start of the course, first year medical students were given four Lists of Structures. On these lists, numbered items were arranged alphabetically; the…

The purpose of the research was to assess the diagnostic efficiency of the Primary Care Posttraumatic Stress Disorder Screen (PC-PTSD) and the Posttraumatic Stress Disorder Checklist (PCL) as clinical screening tools for active duty soldiers recently returned from a combat deployment. A secondary goal was to examine the item-level characteristics…

Background: This study assessed the psychometrics of two measures--the "Matson Evaluation of Drug Side-effects" (MEDS) and the "Akathisia Ratings of Movement Scale" (ARMS)--and examined the symptom profile of akathisia in a sample of people with intellectual disability (ID). Method: Sixty-six participants formed three groups of…

Understanding the extent of commitment to and identification with traditional cultural experiences is essential for working with American Indian people (Whitbeck, 2006). The purpose of this study was to determine the usefulness of a practical measure of enculturation for AI people by examining its reliability and validity within the context of…

Absolute standard setting procedures are recommended for assessment in medical education. Absolute, test-centred standard setting procedures were introduced for written assessments in the Liverpool MBChB in 2001. The modified Angoff and Ebel methods have been used for short answer question-based and extended matching question-based papers,…

Criteria had been proposed for assessing the severity of possible test security violations for computerized tests with high-stakes outcomes. However, these criteria resulted from theoretical derivations that assumed uniformly randomized item selection. This study investigated potential damage caused by organized item theft in computerized adaptive…

Confirmatory factor analyses for ordered-categorical measures probed for differential item functioning on a standardized measure of alcohol dependence across Hispanics (n = 834) and non-Hispanic Caucasians (n = 14,001) in a nationally representative survey of alcohol use in the United States conducted in 1992. Analyses investigated whether 30…

The objective of this study is to explore the potential for developing IRT-based working memory scales for assessing specific working memory components in children (8-13 years). These working memory scales should measure cognitive abilities reliably in the upper range of ability distribution as well as in the normal range, and provide a…

This article discusses the evidence for intervention validity of Functional Behavior Assessment (FBA) in designing support for students with intensive behavioral needs. Since its inclusion into the Individuals With Disabilities Education Act nearly a decade ago, FBA has been the subject of significant research investigating its use and…
