Embedded performance validity tests (PVTs), like Digit Span PVTs from Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), offer a valuable means of evaluating validity without extending administration time. This study investigated the utility of novel indices of performance inconsistency for WAIS-IV Digit Span (DS IRs) in the detection of…

This study aimed to evaluate the tenability of the proposed scoring/interpretive structure for the Woodcock-Johnson IV Test of Cognitive Abilities (WJ IV COG) Standard Battery configuration of subtests using confirmatory factor analysis (CFA) at school age. Results indicated that a three-factor hierarchical model, consistent with the CHC theory…

A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

An accurate assessment of cognitive abilities in populations that differ from the majority in cultural and linguistic characteristics is one of the main challenges in cognitive testing. Previously developed methods for assessment of the validity of cognitive scores in individuals with diverse backgrounds, such as the Culture-Language…

This investigation provides internal consistency reliabilities for the Wechsler Memory Scale--Fourth Edition (WMS-IV) subtest and index discrepancy scores using the standardization samples of the Adult and Older Adult batteries. Subtest reliabilities ranged from 0.00 to 0.93 for Adults and 0.25 to 0.94 for Older Adults. Three of 91 Adult…

The current study provides a methodological review of studies supporting a general factor of intelligence as the primary model for contemporary measures of cognitive abilities. A further evaluation is provided by an empirical evaluation that compares statistical estimates using different approaches in a large sample of children (ages 9-13 years, N…

Experimental measures of working memory that minimize rehearsal and maximize attentional control best predict higher-order cognitive abilities. These tasks fundamentally differ from clinically administered span tasks, which do not control strategy use. Participants engaged in concurrent articulation (to limit rehearsal) or concurrent tapping (to…

When the Differential Ability Scales--Second Edition (DAS-II) was developed, the instrument's content, structure, and theoretical orientation were amended. Despite these changes, the "Technical Handbook" did not report results from exploratory factor analytic investigations, and confirmatory factor analyses were implemented using…

Labels for scores stemming from intelligence tests have been employed since their inception in the United States. The purpose of this study was to systematically identify and document score labels for IQs used during the past 102 years. Using pairs of reviewers, score labels from 40 tests were reviewed, and 61 unique labels were identified.…

The factor structure, the concurrent validity, and test-retest reliability of the Czech translation of the Gifted Rating Scales-School Form [GRS-S; Pfeiffer, S. I., & Jarosewich, T. (2003). "GRS (gifted rating scales) - manual." Pearson] were evaluated. Ten alternative models were tested. Four models were found to exhibit acceptable…

The measurement of perfectionistic cognitions has recently caused disagreement among researchers. Flett, Hewitt, Blankstein, and Gray proposed that perfectionistic cognitions are unidimensional. However, after re-examining the factor structure of the instrument used to measure perfectionistic automatic thoughts (Perfectionism Cognitions Inventory…

Brewer, Young, and Barnett reported a comprehensive psychometric evaluation of a new adult theory of mind measure (A-ToM) with a sample of high-functioning autism spectrum disorder (ASD) adults. Although correlations with existing theory of mind (ToM) instruments (i.e., the Strange Stories; the Frith- Happé animations) were reported, relationships…

W scores are used in a number of commercially available tests. Due to their complex nature, it can be hard for applied researchers and practitioners to understand them or even acquire information about them beyond what is provided in technical manuals. In this article, we provide information regarding the background and derivation of W scores that…

This study evaluated the psychometric quality of a computerized adaptive testing (CAT) version of the general cognitive ability test (GCAT), using a simulation study protocol put forth by Han, K. T. (2018a). For the needs of the analysis, three different sets of items were generated, providing an item pool of 165 items. Before evaluating the…

The present study examined whether global ability influences on reading, writing, and math achievement are generalizable across gender in children and adolescents in Grades 1 to 4 (n = 1,276), 5 to 8 (n = 1,265), and 9 to 12 (n = 1,042) using multiple group structural equation modeling with the standardization samples for the Woodcock-Johnson IV.…
