The broad autism phenotype is the phenotypic expression of the primary characteristics of autism. However, currently available tests do not agree with the two-domain operationalization of broad autism phenotype or autism, and their internal structure has shown instability across applications. This study presents the Broad Autism…

Unfolding item response theory (IRT) models are important alternatives to dominance IRT models in describing the response processes on self-report tests. Their usage is common in personality measures, since they indicate potential differentiations in test score interpretation. This paper aims to gain a better insight into the structure of trait…

Despite several psychometric advantages over the 50-item Autism Spectrum Quotient, an instrument used to measure autistic traits, the abridged AQ-28 and its cross-cultural validity have not been examined as extensively. Therefore, this study aimed to examine the factor structure and measurement invariance of the AQ-28 in 818 Dutch (M[subscript…

The University of Reading Learning Gain project is a three-year longitudinal project to test and evaluate a range of available methodologies and to draw conclusions on what might be the right combination of instruments for the measurement of Learning Gain in higher education. This paper analyses the validity of a measure of critical thinking…

The main purpose of this study was to conduct a validation analysis of student surveys of teaching effectiveness implemented at Bangkok University, Thailand. This study included three phases; survey development, a pilot study, and a full implementation study. Four sources of validity evidence were collected to support intended interpretations and…

Reading comprehension is often treated as a multidimensional construct. In many reading tests, items are distributed over reading process categories to represent the subskills expected to constitute comprehension. This study explores (a) the extent to which specified subskills of reading comprehension tests are conceptually conceivable to…

Despite decades of research and debate, the issue of unequal outcomes continues to be a concern in educational systems worldwide. In England, published data relating to pupils' attainment across ethnic groups and by class indicators has been used to demonstrate continued inequalities in schools. This article attempts to deconstruct the…

Psychometric practice does not always converge with the advances of psychometric theory. In order to investigate this gap, the authors focus on the 10 most used psychological tests in Europe, as identified by recent surveys. The article analyzes test manuals published in 6 different European countries for these 10 most used tests. A total of 32…

Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

The user of the Vocational Interest Survey (VIS) has available a number of interpretative approaches at various descriptive and qualitative levels. This report provides a brief outline of the various approaches. Whenever all six scales of the VIS are administered, the client's total score on all six scales should be within the average range. The…

The aptitude tests used in Queensland (Australia) to standardize secondary school leavers' school evaluations was assessed for reliability with various student group sizes and for a range of abilities. The error found was significant for small and moderately sized groups, suggesting the need for care in test interpretation. (Author/MSE)

The School Subjects Attitude Scales is an instrument for measuring students' attitudes toward school subjects for grades 5-12. Twenty-four bipolar word pairs are used with evaluation, usefulness, and difficulty scales. The word pairs were selected on the basis of discussions and analysis of trial forms. Results can be used in program evaluation…

This paper addresses the problem of how to place students in a sequence of hierarchically related courses from an (empirical) Bayesian point of view. Based on a minimal set of assumptions, it is shown that optimal mastery rules for the courses are always monotone and a nonincreasing function of the scores on the placement test. On the other hand,…

The Quest program offers a comprehensive test and questionnaire analysis environment by providing a data analyst (a computer program) with access to the most recent developments in Rasch measurement theory, as well as a range of traditional analysis procedures. This manual helps the user use Quest to construct and validate variables based on…

This article reviews the revised KeyMath Revised-Normative Update American and Canadian editions, and a draft version of the 1999 pending revision. The assessment instrument is intended to test basic mathematical concepts, operations, and applications of students in grades K-12. Its administration, standardization, reliability, and validity are…
