The Cattell-Horn-Carroll (CHC) theory of cognitive abilities has helped advance understanding regarding the relations between specific cognitive abilities and academic achievement in definite domains. However, questions over the generalisability of this research, as well the moderating effect age has on the strength of cognitive-achievement relations, means that further research is needed. This study therefore investigated the capacity for using the Multidimensional Aptitude Battery — II (MAB-II), a group-administered test of cognitive ability, to further CHC-driven research in Australia. After adapting the MAB-II verbal subtests to be suitable for use with an Australian sample, 179 adults completed the measure. Results were analaysed using both classical test and item response theory. Findings indicated that despite the MAB-II not being developed using CHC theory, the structure of the test appeared to conform to this model. Further, while an adequate number of subtests hypothesised to measure the CHC domains of Comprehension-knowledge (Gc) and Visual processing (Gv) were found to perform well psychometrically, the Arithmetic, Picture Arrangement, and Digit Symbol subtests returned questionable results. Given the advantages a group-administered test of CHC cognitive abilities would provide to CHC-driven research in Australia, suggestions for future modifications and adaptations of the test are provided.

Age, education, and gender are the most common covariates used to define normative standards against which neuropsychological (NP) performance is interpreted, but influences of other demographic factors have begun to be appreciated. In developing nations, urban versus rural residence may differentially affect numerous factors that could influence cognitive test performances, including quality of both formal and informal educational experiences and employment opportunities. Such disparities may necessitate corrections for urban/rural (U/R) status in NP norms. Prior investigations of the U/R effect on NP performance typically have been confounded by differences in educational attainment. We addressed in this by comparing the NP performance of large, Chinese urban (Yunnan Province, n = 201) and rural (Anhui Province, n = 141) cohorts of healthy adults, while controlling for other demographic differences. Although the groups did not differ in global NP scores, a more complex pattern was observed within specific NP ability domains and tests. Urban participants showed better performance in select measures of processing speed and executive functions, verbal fluency, and verbal learning. Self-reported daily use of academic skills was predictive of many U/R differences. Controlling for academic skill use abrogated most U/R differences but revealed rural advantages in select measures of visual reasoning and motor dexterity. (JINS, 2011, 17, 000–000)

Adaptations of the National Adult Reading Test (NART) for assessing premorbid intelligence in languages other than English requires (a) generating word-items that are rare and do not follow grapheme-to-phoneme mappings common in that language, and (b) subsequent validation against a cognitive battery normed on the population of interest. Such tests exist for Italy, France, Spain, and Argentina, all normed against national versions of the Wechsler Adult Intelligence Scale. Given the varieties of Spanish spoken in the United States, the adaptation of the Spanish Word Accentuation Test (WAT) requires re-validating the original word list, plus possible new items, against a cognitive battery that has been normed on Spanish-speakers from many countries. This study reports the generation of 55 additional words and revalidation in a sample of 80 older, Spanish-dominant immigrants. The Batería Woodcock-Muñoz Revisada (BWM-R), normed on Spanish speakers from six countries and five U.S. states, was used to establish criterion validity. The original WAT word list accounted for 77% of the variance in the BWM-R and 58% of the variance in Ravens Colored Progressive Matrices, suggesting that the unmodified list possesses adequate predictive validity as an indicator of intelligence. Regression equations are provided for estimating BWM-R and Ravens scores from WAT scores. (JINS, 2006, 12, 391–399.)
