Classical methods for detecting outliers deal with continuous variables. These methods are not readily applicable to categorical data, such as incorrect/correct scores (0/1) and ordered rating scale scores (e.g., 0,..., 4) typical of multi-item tests and questionnaires. This study proposes two definitions of outlier scores suited for categorical…

This article deals with the investigation of the psychometric quality and constructs validity of algebra word problems generated by means of a schema-based version of the automatic min-max approach. Based on review of the research literature in algebra word problem solving and automatic item generation this new approach is introduced as a…

This study reports on a new instrument, the Academic Rational Beliefs Scale, designed to measure college students' academic beliefs along a rational-irrational continuum. The new instrument is potentially useful when working with students experiencing academic difficulties. Information about test construction, reliability, validity, and…

The high prevalence and serious consequences associated with rape makes its prevention an important social work goal. Rape prevention necessitates understanding the attitudes and personality characteristics of actual and potential rapists. Within the research on attitudinal correlates of rape, hypermasculinity consistently emerges as one of the…

Two quasi-experimental field studies were conducted to evaluate the psychometric equivalence of computerized and paper-and-pencil job satisfaction measures. The present research extends previous work in the area by providing better control of common threats to validity in quasi-experimental research on test mode effects and by evaluating a more…

This study investigated the Jordanian regular education teachers' knowledge of learning disabilities and whether this knowledge differed as a function of selected variables. The sample consisted of 405 regular classroom teachers teaching 1st- to 6th- grade students in 30 schools in three Jordanian districts. Teachers completed a 40-item test…

Background: Relatively little is known about the genetic architecture of childhood behavioral disorders in very young children. Method: In this study, parents completed the Infant-Toddler Social and Emotional Assessment, a questionnaire that assesses symptoms of childhood disorders, as well as socio-emotional competencies, for 822 twin pairs…

Despite findings that depression is a risk factor for heart disease and for death following cardiac events and that depressed cardiac patients experience significantly reduced quality of life and are less likely to follow treatment regimens, depression is neither adequately identified nor treated in cardiac patients. Recent calls in the literature…

This article explores the decision making in developing and starting a partnership between three universities using the decision-making models developed by Graham Allison in 1971 and updated in 1999. University partnerships are complicated and require more than one decision-making model to explain all the significant decisions that are make in…

Context: Health disparities between rural and urban communities are well documented. There are many suggested causes and many proposed solutions but no one-size-fits-all answer. The most successful community interventions have been introduced by communities themselves. However, before communities invest in such interventions, each group must…

Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of…

This paper presents selected findings from an ESRC-funded research project examining the choices and occupational aspirations of 59 students approaching the end of their compulsory schooling. It concentrates on the development of a choice model conceptualising the decisionmaking processes of the young people involved in the study, whilst avoiding…

Background: Most standardized intelligence tests require more than 1hour for administration, which is problematic when evaluating individuals with intellectual disabilities and developmental disabilities (IDDD), because a significant proportion of these individuals can not tolerate lengthy evaluations. Furthermore, most standardized intelligence…

English language learners with disabilities (ELLWD) face many challenges in their academic career. Learning a new language and coping with their disabilities create obstacles in their academic progress. Variables relegating accessibility of assessments for students with disabilities and ELL students may seriously hinder the academic performance of…

This document describes the breadth of the research being conducted in 2008 by the Research and Development Division at Educational Testing Service (ETS). The research described falls into three large categories: (1) Research supported by the ETS research allocation; (2) Research funded by testing programs at ETS; and (3) Research funded by…
