There is significant debate over the value and ethics of IQ testing for children, including those from diverse cultural groups, particularly in light of studies examining performance on various subtests that are uncovering important processing differences between cultural and linguistic groups (Sotelo-Dynega, Ortiz, Flanagan, & Chaplin, 2013).…

Recently, Gotham et al. ("2007") proposed revised algorithms for the Autism Diagnostic Observation Schedule (ADOS) with improved diagnostic validity. The aim of the current study was to replicate predictive validity, factor structure, and correlations with age and verbal and nonverbal IQ of the ADOS revised algorithms for Modules 1 and 2…

Examined the validity of a subtest combination as an estimate of the Wechsler Intelligence Scale For Children (Revised) Full Scale IQ. Satisfactory correlations were found between the short and full scale IQ. The short form did not allow precise IQ estimation but shows promise as a screening device. (Author)

Examined the reliability and predictive validity of the WISC-R with Navajo children (N=40). Internal consistency reliability estimates of WISC-R subtests as well as composites were found to be low for the Navajo subjects. The predictive validity of the WISC-R IQ scales was similarly found to be very low. (Author)

Assessed validity of the Personality Inventory for Children (PIC) using the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wide Range Achievement Test (WRAT) as criterion instruments. The cognitive triad of the PIC was minimally correlated with all intelligence quotient measures and significantly correlated only for reading and…

Analysis of correlations between Verbal and Full Scale IQ scores for 231 high-IQ psychiatric outpatients indicated that Verbal IQ appears partially valid as a WAIS short form for this higher IQ group. Results are interpreted in terms of Resnick and Entin's short form validity criteria. (Editor/SJL)

Validity of the Cognitive Levels Test (CLT) was evaluated by correlating test scores of 48 gifted 10-year-olds with scores on the Stanford-Binet intelligence scale as preschoolers as well as with scores from the California Achievement Test. Results indicated high degrees of CLT validity in both measuring cognitive ability and predicting academic…

The Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to 95 elementary students referred because of either learning problems or potential giftedness. SIT scores predicted SBIV verbal scores more accurately than composite scores. Overall the SIT predicted SBIV scores better for students with learning…

Data from the Wechsler Adult Intelligence Scale-Revised (WAIS-R), grade point average (GPA) after 2 semesters of full-time enrollment, and selected student characteristics were compared for 49 learning-disabled college students. WAIS-R results were not generally predictive of academic success, although Comprehension and Similarities subtests…

The concurrent validities of 3 short forms of the Wechsler Adult Intelligence Scale (WAIS) were compared for their prediction of full-scale IQ for 145 male and 159 female psychiatric inpatients. Results support previous research showing better predictive accuracy for L. C. Ward's (1990) seven-subtest short form than the others. (SLD)

Critiques Walker's article in this issue. Argues that Walker's data do not meet technical standards regarding individual placement tests for normative comparisons, interjudge reliability, or predictive validity, and therefore do not justify the use of the Gesell test to place children in developmental kindergarten or transitional first grade. (GLR)

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)

The long term predictive validity of the Wechsler Intelligence Scale for Children (WISC) and the Bender Visual Motor Gestalt Test for Children, when used for the educational placement of exceptional students, was investigated. In 1971, 225 learning disabled elementary school students were tested on the WISC and the Bender. The students were…

This book addresses the question of what tests are measures of. Intelligence, achievement, and personality tests not based on empirical investigation have questionable validity. Some researchers now suspect that almost all tests given to students in all subjects, as well as general tests of intelligence and personality, are essentially language…
