Schmank, Christopher J.; Goring, Sara Anne; Kovacs, Kristof; Conway, Andrew R. A. – Journal of Intelligence, 2019
The positive manifold--the finding that cognitive ability measures demonstrate positive correlations with one another--has led to models of intelligence that include a general cognitive ability or general intelligence (g). This view has been reinforced using factor analysis and reflective, higher-order latent variable models. However, a new theory…

Nuñez-Polo, Mercedes H. – Journal of Mental Health Research in Intellectual Disabilities, 2022
Introduction: The aim of this study is to validate a Spanish version of the Impact of Event Scale on People with ID (IES-ID). Methods: IES-ID was administered to adults with ID (n = 120), analyzing internal consistency, inter-rater and test-retest reliability, criterion validity, construct validity and feasibility. Results: Good internal…

Elwin, Marie; Schröder, Agneta; Ek, Lena; Wallsten, Tuula; Kjellin, Lars – Journal of Autism and Developmental Disorders, 2017
We identified clusters of atypical sensory functioning adults with ASC by hierarchical cluster analysis. A new scale for commonly self-reported sensory reactivity was used as a measure. In a low frequency group (n = 37), all subscale scores were relatively low, in particular atypical sensory/motor reactivity. In the intermediate group (n = 17)…

Miller, Delyana I.; Davidson, Patrick S. R.; Schindler, Dwayne; Messier, Claude – Journal of Psychoeducational Assessment, 2013
New editions of the Wechsler Adult Intelligence and Memory scales are now available. Yet, given the significant changes in these new releases and the skepticism that has met them, independent evidence on their psychometric properties is much needed but currently lacking. We administered the WAIS-IV and the Older Adult version of the WMS-IV to 145…

Windsor, Tim D.; Curtis, Rachel G.; Luszcz, Mary A. – Developmental Psychology, 2015
Having a sense of purpose is recognized as an important resource for maintaining health and well-being over the life span. We examined associations of individual differences in sense of purpose with levels and rates of change in indices of aging well (health, cognition, and depressive symptoms) in a sample of 1,475 older adults (M[subscript age] =…

Bowden, Stephen C.; Saklofske, Donald H.; Weiss, Lawrence G. – Assessment, 2011
Examination of measurement invariance provides a powerful method to evaluate the hypothesis that the same set of psychological constructs underlies a set of test scores in different populations. If measurement invariance is observed, then the same psychological meaning can be ascribed to scores in both populations. In this study, the measurement…

Golay, Philippe; Lecerf, Thierry – Psychological Assessment, 2011
According to the most widely accepted Cattell-Horn-Carroll (CHC) model of intelligence measurement, each subtest score of the Wechsler Intelligence Scale for Adults (3rd ed.; WAIS-III) should reflect both 1st- and 2nd-order factors (i.e., 4 or 5 broad abilities and 1 general factor). To disentangle the contribution of each factor, we applied a…

Egeland, Jens; Bosnes, Ole; Johansen, Hans – Assessment, 2009
Confirmatory Factor Analyses (CFA) of the Wechsler Adult Intelligence Scale-III (WAIS-III) lend partial support to the four-factor model proposed in the test manual. However, the Arithmetic subtest has been especially difficult to allocate to one factor. Using the new Norwegian WAIS-III version, we tested factor models differing in the number of…

Puhan, Biranchi N. – Educational and Psychological Measurement, 1981
One hundred undergraduate arts students were tested on all the scales of Wechsler Adult Intelligence Scales (WAIS) and the Differential Aptitude Tests. Varimax solutions were extracted on WAIS scores under four analytic conditions. No progressive increment in the WAIS communalities was marked as the marker variables increased. (Author/RL)

Wicherts, Jelte M.; Dolan, Conor V.; Hessen, David J.; Oosterveld, Paul; van Baal, G. Caroline M.; Boomsma, Dorret I.; Span, Mark M. – Intelligence, 2004
The gains of scores on standardized intelligence tests (i.e., Flynn effect) have been the subject of extensive debate concerning their nature, causes, and implications. The aim of the present study is to investigate whether five intelligence tests are measurement invariant with respect to cohort. Measurement invariance implies that gains over the…

Parker, Kevin – Journal of Consulting and Clinical Psychology, 1983
Factor analyzed the Wechsler Adult Intelligence Scale-Revised (WAIS-R) across nine age groups in the standardization sample. When three- and four-factor analyses were performed, the familiar three-factor structure (Verbal Comprehension, Perceptual Organization, and Freedom From Distractibility) was clearly visible.

Bowden, Stephen C.; Cook, Mark J.; Bardenhagen, Fiona J.; Shores, E. Arthur; Carstairs, Jane R. – Intelligence, 2004
Confirmatory factor analysis of Australian adaptations of combined Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wechsler Memory Scale-Revised (WMS-R) scores was conducted in a sample of 277 participants undergoing investigation for neurological disorders. The best-fitting model was a six-factor model representing the latent abilities of…

Alm, Jan; Kaufman, Alan S. – Journal of Learning Disabilities, 2002
Factor analysis of the Swedish version of the Wechsler Adult Intelligence Scale-Revised on 88 adults with dyslexia showed a three-factor structure: a verbal comprehension (VC) factor, a perceptual organization (PO) factor, and a freedom from distractibility (FD) factor. The PO factor had the highest scores and the FD the lowest. (Contains…
