Assessing job applicants' general mental ability online poses psychometric challenges due to the necessity of having brief but accurate tests. Recent research (Myszkowski & Storme, 2018) suggests that recovering distractor information through Nested Logit Models (NLM; Suh & Bolt, 2010) increases the reliability of ability estimates in…

This investigation assessed the ability of the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) short forms to estimate both index and IQ scores in a large, mixed clinical sample (N = 809). More specifically, a commonly used modification of Ward's seven-subtest short form (SF7-A), a recently proposed index-based SF7-C and eight-subtest…

The question regarding the appropriateness of the use of tests of intelligence and cognitive abilities developed in the United States to assess people from other countries was renewed in the debate between Suen and Greenspan (2008) and Sanchez-Escobedo and Hollingworth (2009). This controversy arose from challenges in the translation, adaptation,…

Administered three Wechsler adult intelligence scales to 72 undergraduates and tested the quality of means, variances, and covariances, utilizing subtest scale scores and IQs. Results indicated that the three scales were not parallel. Generally, the subtest scaled scores exhibited less similarity across the three scales than the IQ estimates.…

An investigation of three intelligence tests reveals that the Slosson shows signs of becoming a legitimate substitute for other intelligence tests, while the Columbia yielded erratic results for the mentally retarded participants in this study. (Author/KM)

From published data on the Wechsler subtest performance of mild and borderline mentally retarded persons, 4,304 protocols from 4,004 individuals were collated and their subtest patterns on other Wechsler instruments were compared. Results indicate that mildly retarded groups tend to score lower on subtests that better measure general intelligence.…

Examined the relative utility of the Peabody Picture Vocabulary Test, the Quick Test, and the Revised Beta as measures of intelligence in relation to the Wechsler Scales. Brief measures were not acceptable Wechsler substitutes with juvenile delinquents. (Author)

Results indicate that because there is not an equivalent relationship between the WISC and WAIS, classification or retardation level and prognostic formulation using these tests should be made cautiously. (Author/CB)

It was found that the General Cognitive Index scores of the McCarthy Scales correlated well with the Stanford-Binet IQ scores. However, 40 of the 44 subjects scored higher on the Stanford-Binet than on the McCarthy Scales. (Author)

Fabricated test protocols were used to study how effectively examiners agree in scoring ambiguous WISC-R responses. The results suggest that, even with the improved WISC-R manual, scoring remains a difficult and challenging task. (Author)

Investigated geographic differences in Wechsler Adult Intelligence Scale (WAIS) results by comparing 60 Hawaiian and 60 mainland United States psychiatric outpatients. The influence of pidgin English led to expectations that Hawaiian subjects would have significantly lower WAIS Verbal scores than mainland subjects. Data verified these…

Assessed the degree of comparability between the tests over time for two samples of referred adolescents of borderline intelligence. Results indicated that the Wechsler Adult Intelligence Scale-Revised significantly overestimated the Wechsler Intelligence Scale for Children-Revised by three to five points. Differences were most marked at the lower…

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old educable mentally retarded students, who were matched according to sex and race. Results suggest that many children classified as "Borderline" or slightly above the WISC will be classified as "Mentally Deficient" by…

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)
