When comparing relations and means of latent variables, it is important to establish measurement invariance (MI). Most methods to assess MI are based on confirmatory factor analysis (CFA). Recently, new methods have been developed based on exploratory factor analysis (EFA); most notably, as extensions of multi-group EFA, researchers introduced…

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 Wechsler Individual Achievement Test (WIAT-4) is the latest iteration of a popular instrument that psychologists employ to assess academic achievement. The WIAT-4 authors make both pragmatic and measurement claims about the instrument. The pragmatic claims involve being useful for identifying individuals in certain academic achievement-related…

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]…

The assessment of noncognitive traits is challenging due to possible response biases, "subjectivity" and "faking." Standardized third-party evaluations where an external evaluator rates an applicant on their strengths and weaknesses on various noncognitive traits are a promising alternative. However, accurate score-based…

The National Association of School Psychologists' Model for Comprehensive and Integrated School Psychological Services (2010a), often referred to as the National Association of School Psychologists' Practice Model, describes the comprehensive range of professional skills and competencies available from school psychologists across 10 domains. The…

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…

This study tested five confirmatory factor analytic (CFA) models of the Positive Affect Negative Affect Schedule (PANAS) to provide validity evidence based on its internal structure. A sample of 223 club sport athletes indicated their emotions during the past week. Results revealed that an orthogonal two-factor CFA model, specifying error…

The measurement of higher-order competencies within a tertiary education system across countries presents methodological challenges due to differences in educational systems, socio-economic factors, and perceptions as to which constructs should be assessed (Blömeke, Zlatkin-Troitschanskaia, Kuhn, & Fege, 2013). According to Hart Research…

Double cross-validation of a test battery against multiple criterion variables found the first general factor accounts for most criterion variance in cross-validated regression weights. Small contributions are made by mechanical/technical and psychomotor factors. It appears a common general factor plays the major role in validity for a range of…

The study investigated the subtest items included in the test. (JS)

The revised ITPA promises to have continued wide application. It successfully measures general linguistic ability and intelligence, and to a limited extent it successfully measures aspects of cognitive ability. However, it fails to measure many of the cognitive domains that it was designed to measure. (Author)
