Both testlet design and hierarchical latent traits are fairly common in educational and psychological measurements. This study aimed to develop a new class of higher order testlet response models that consider both local item dependence within testlets and a hierarchy of latent traits. Due to high dimensionality, the authors adopted the Bayesian…

Background: Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale-Third…

The Chinese revision of the Wechsler Adult Intelligence Scale was factor analyzed for 55 Chinese subjects with mental retardation. Results indicated a two-factor solution comprising Verbal Comprehension and Perceptual Organization factors. Analysis found no important differences in factor structure between the Chinese subjects and low-intelligence…

Criteria were developed to assess sexual and racial item content bias for every item from six IQ tests. Each reference was judged as either stereotyped or not sterotyped. This analysis pointed out an overwhelming sexual and racial imbalance in item content. (Author/RL)

Items showing sex differences on the revised Wechsler Adult Intelligence Scale (WAIS-R) were studied. In a sample of 206 young adults (110 males and 96 females), 15 items demonstrated significant sex differences, but there was no relationship of item-specific gender content to sex differences in item performance. (SLD)

Intersubtest scatter on the Wechsler Adult Intelligence Scale-Revised for China (WAIS-RC) for 1,979 subjects was evaluated and compared with that of the WAIS-R standardization sample. Findings were similar, and differences in scatter range may be explained by cultural differences in values, educational approaches, and educational opportunities.…

A cross-racial comparison of the Wechsler Adult Intelligence Scale (WAIS) was made with the revised version, the WAIS-R. Three groups of Anglo, Black, and Mexican-American male college students were administered both versions of the WAIS on the same day. Significant differences were found among the racial groups. (Author/LMO)

To examine the issue of item bias within the context of the revised Wechsler Adult Intelligence Scale (WAIS-R), judgments as to perceived item bias were sought. Independent raters nominated 53 WAIS-R items as containing possible bias. White and non-white college students nominated items as racially or sexually biased. Whereas 10 items were judged…

Reports possible validity of particular American Indian cognitive style based on the Bannatyne categories of the Wechsler Scales. Found statistically significant pattern of spatial ability, sequential ability, and verbal conceptual ability in 75 junior and senior high school Yakima Indian students. (LFL)

Investigates the relationship of Minnesota Multiphasic Personality Inventory-2 Scales L, K, and Mf with Verbal, Performance, and Full Scale IQs from the Wechsler Adult Intelligence Scale-Revised; achievement scores in reading, spelling, and arithmetic; and total years of education as self-reported by the study research participants. (RJM)

Professional assessment of mental retardation (MR) and learning disabilities (LD) is crucial to the implementation of P.L. 94-142 because it necessarily precedes the employment of trained teachers and because a plan for remediation depends on accurate assessment. Intelligence is a key element in the identification of MR-LD, but competent, fair…
