Article Abstract
Objective: To examine the clinical utility of Wechsler Adult Intelligence Scale-IV (WAIS-IV) Matrix Reasoning in limited educated recently arrived immigrants in Denmark.
Method: Participants were 64 limited educated (0-9 years' education) independently living adult immigrants primarily from Middle Eastern and Sub-Saharan African countries who completed WAIS-IV Matrix Reasoning as well as demographic, and medical questionnaires.
Results: Thirty-eight participants (59%) scored more than two standard deviations below the Scandinavian mean (scaled score < 4). Performances were significantly associated with years of education but not with occupational status, years of residence in Denmark, or Danish language skills. The most common error types were repetition errors (15.84%) and incomplete correlate errors (10.47%), with a strong trend for a higher proportion of repetition errors in participants with <5 years of education.
Conclusions: The findings indicate that WAIS-IV Matrix Reasoning underestimates cognitive functioning in limited educated recently arrived immigrants, thus calling its clinical utility into question.
Objective: The present exploratory study aimed to examine the potential impact of culture on cognitive skills and intelligence by comparing the Japanese Wechsler Adult Intelligence Scale-IV (WAIS-IV) (JW) subtests, IQs, and index scores to those of the U.S. WAIS-IV (USW).
Objective: To delineate score differences between the Wechsler Adult Intelligence Scale-IV (WAIS-IV) and the WAIS-IV México in the assessment of balanced bilingual Mexican Americans and to determine the efficacy of five hold measures in predicting summary scores in each version.
Methods: Hold measures were WAIS-IV Information, Vocabulary, and Matrix Reasoning subtests, picture vocabulary, and the Test of Premorbid Function (English)/Word Accentuation Test (Spanish). Using a repeated measures design, 60 neurologically intact participants were tested in a counterbalanced order, with WAIS-IV version as the repeated measure (mean intertest interval = 5.
(1) Background: The Wechsler intelligence scales are very popular in clinical practice and for research purposes. However, they are time consuming to administer. Therefore, researchers and psychologists have explored the possibility of shorter test battery compositions.
Objective: Most neuropsychological tests were developed without the benefit of modern psychometric theory. We used item response theory (IRT) methods to determine whether a widely used test - the 26-item Matrix Reasoning subtest of the WAIS-IV - might be used more efficiently if it were administered using computerized adaptive testing (CAT).
Method: Data on the Matrix Reasoning subtest from 2197 participants enrolled in the National Neuropsychology Network (NNN) were analyzed using a two-parameter logistic (2PL) IRT model.
