The Youth Self-Report Form's (YSR's) factor model was derived from traditional exploratory factor analytical procedures. Assuming appropriate model specification, psychometrically invariant items, and that its items provide useful psychometric information across nations omitted from its normative samples, the YSR is widely used in cross-national…

Using generalizability theory, this study examined both the rating variability and reliability of ESL students' writing in the provincial English examinations in Canada. Three years' data were used in order to complete the analyses and examine the stability of the results. The major research question that guided this study was: Are there any…

Confirmatory factor analysis for ordered-categorical measures (CFA-OCM) and rating scale item response theory (IRT) analyses explore measurement bias across gender on the Children's Depression Inventory (CDI) in a community sample of 779 children in the third and sixth grades. Given the set of statistical criteria, IRT and CFA-OCM generally…

Recent research has shown that the technical adequacy of assessments for special student populations is relatively undeveloped compared to their general education counterparts; that is, the technical evidence provided and the methods by which this evidence is established do not necessarily account for the unique characteristics of special needs…

Background: Recent changes in higher education in the UK have led to much discussion about the performance of men and women students with different methods of assessment. Aim: To see whether or not there were differences between the marks awarded to men and women final-year psychology students as a function of the modes of assessment used. Method:…

In their article, "Disconfirmation of the Predictive Validity of the Self-Appraisal Questionnaire in a Sample of High-Risk Drug Offenders," criminologists Mitchell and MacKenzie (2006) purported to evaluate psychometric properties of the Self-Appraisal Questionnaire (SAQ), the first self-report risk/need measure estimating violent and nonviolent…

Thomas Jefferson recognized the value of reason and scientific experimentation in the eighteenth century. This chapter extends the idea in contemporary ways to standards that may be used to judge the ethical propriety of randomized trials and the dependability of evidence on effects of social interventions.

This study used meta-analysis research techniques to determine if there are differences in General Aptitude Test Battery (GATB) validities and test scores between males and females. The sample consisted of 26,111 subjects from 122 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. Four approaches were…

The concepts of language proficiency, limited language proficiency, and comparably limited language proficiency are examined. Studies critical of the instruments used for making assessments according to these concepts are reviewed. The effects of these concepts on proposed legislation involving bilingual education are discussed. It is suggested…

This paper presents a promising new item bias detection technique that derives practical appeal from its simplicity and economy, and provides data relating to the method's consistency across samples. The proposed regression on item characteristics (RIC) method is a straightforward and inexpensive approach to the study of item bias, based on…

This paper criticizes the Future Events Test and conclusions drawn from it on the grounds that the test contains sex-biased items and that locus of control scales have shown no reliable sex differences. (GO)

A two-factor analysis of variance with multiple measurements on one factor was conducted among the 40 items of the Vocabulary test of the Test of English as a Foreign Language (TOEFL) for six language groups. All sources of variance were found significant beyond the one per cent level. (Author/RC)

Questions are addressed that focus on why lower class and minority group test takers score lower on standardized tests than their middle class Anglo counterparts. The questions include the following: (1) In what ways can dialect differences affect testing? (2) How can dialect differences directly affect a test of language? (3) Shouldn't standard…

The paper states the need for providing services to handicapped youthful offenders. Obstacles to compliance with P.L. 94-142, the Education for All Handicapped Children Act, for this population are noted, including lack of staff and funding. Research is cited to show the extent of the problem and project the effects of inadequate programing. The…

The stability of selected indices for detecting differential item performance (item bias), from one randomly equivalent sample to another, is addressed. Some recent research has criticized these indices as too unreliable for utility in measuring bias in achievement test items. Using data from a national testing of the ACT Assessment, however, this…
