Validity in psychometrics refers to the degree to which evidence and theory supports the interpretations drawn from a test, and Messick's Contemporary Validity Theory (1994) includes several facets with well-established evidence collection methods. However, there is a lack of consensus on appropriate methods of evaluating the facet of…

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…

The purpose of this paper is to examine the factorial invariance of the Wechsler Intelligence Scale for Children--Fifth Edition (WISC-V) between genders in a sample of Black students in an urban, public school district. Few researchers test the validity of cognitive assessments on Black samples and even fewer do so utilizing samples other than…

The Woodcock-Johnson Tests of Achievement, Fourth Edition (WJ IV ACH) is purported to align with Cattell-Horn-Carroll (CHC) theory and offers upward of 20 scores within its interpretive and scoring system. The Technical Manual does not furnish validity evidence for the scores reported by the scoring system, suggesting that evidentiary support may…

The factor structure of the Wechsler Intelligence Scale for Children--Fourth Edition, Italian adaptation (WISC-IV Itaian; Orsini, Pezzuti, & Picone, 2012; Wechsler, 2012) standardization sample was examined with exploratory factor analytic methods (EFA) not included in the "Technical Manual." Principal-axis extraction followed by…

Background: There is inadequate information regarding the factor structure of the Wechsler Intelligence Scale for Children -- Fifth UK Edition (WISC-V[superscript UK]; Wechsler, 2016a, Wechsler Intelligence Scale for Children-Fifth UK Edition, Harcourt Assessment, London, UK) to guide interpretation. Aims and methods: The WISC-V[superscript UK]…

In this study we investigated the internal factor structure of a large-scale K--12 assessment of English language proficiency (ELP) using samples of fourth- and eighth-grade English learners (ELs) in one state. While U.S. schools are mandated to measure students' ELP in four language domains (listening, reading, speaking, and writing), some ELP…

This study assessed the factor structure of the Test of English for International Communication (TOEIC®) Listening and Reading test, and its invariance across subgroups of test-takers. The subgroups were defined by (a) gender, (b) age, (c) employment status, (d) time spent studying English, and (e) having lived in a country where English is the…

Background: This study investigated the factor structure and factorial invariance of an English Placement Exam (EPE) from 1998 to 2011 to provide evidence for both the appropriateness of the test scores interpretations and for a validity argument. Methods: Test performance data collected from 38,632 freshmen non-English majors from a university in…

Accurate interpretations of large-scale assessment results and sound judgments about students' mathematical literacy depend on these assessments' validity and reliability. One important type of evidence towards this validation is the dimensionality analysis, which explores the conformity between the intended factorial structure (related closely to…

This study examined the factor structure of the listening and reading sections of the revised Test of English for International Communication (TOEIC[R]) test. The data from the TOEIC IP (institutional program) test taken by 569 English learners were randomly split into two samples (n = 285 vs. 284). Four models (higher-order, correlated,…

Multisample confirmatory factor analysis (MCFA) and latent mean structures analysis (LMS) were used to test measurement invariance and latent mean differences on the Kaufman Adolescent and Adult Intelligence Scale[TM] (KAIT) across males and females in the standardization sample. MCFA found that the parameters of the KAIT two-factor model were…

Reviews WISC-R factor analytic findings for developing a scheme for regrouping WISC-R subtests, consisting of verbal comprehension and spatial subtests. Subtests comprising these groupings are shown to have more common variance than specific variance and cluster together consistently across the samples of WISC-R scores. (Author/JAC)

The factor structure of scores on the Adult Manifest Anxiety Scale-College Version (AMAS-C), a new self-report measure of chronic, manifest anxiety, is examined across gender for a sample of 943 college students (608 women and 335 men). Values for the coefficient of congruence and salient variable similarity index are calculated between each of…

A factor analysis was conducted of scores on the revised Learning Style Inventory of D. A. Kolb from 718 accounting students from 2 large state universities. Results support two bipolar learning dimensions different from those theorized and only one separate learning ability. Caution in interpreting scores is advised. (SLD)
