Investigated the validity of the Luria-Nebraska Intellectual Processes Scale (IPS) as a substitute for the Wechsler Adult Intelligence Scale (WAIS). IPS scores were correlated with the three WAIS IQs, and regression equations were computed to obtain estimated Verbal IQ, Performance IQ, and Full Scale IQ. (Author)

The test-retest reliability and predictive validity of developmental quotients (DQs) derived from the Cattell Infant Intelligence Scale was assessed with 83 children with mental retardation, age 30 months or more. Scores were impressively stable on retest. DQs derived from the Bayley Scales of Infant Development were superior to Cattell DQs in…

Statistical analyses of scores on subtests of the Intelligence Test for Visually Impaired Children were done for two groups of children, either with or without usable vision. Results suggest that the battery has differential factorial and predictive validity. (Author/DB)

This study investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test, using the Slosson Intelligence Test For Children and Adults as the predictor. Results indicate that the Slosson IQ significantly predicts Wide Range standard scores. (Author)

IQ tests were viewed solely as predictors in this investigation. The results revealed equal but very low within-ethnic-group correlations between IQ and achievement measures administered concurrently prior to desegregation and for tests administered one and two years following desegregation.

Notes that there is no pedagogical or psychological research or evaluation to date to justify the use of norm-referenced standardized tests as precision tools. At best, they are experimental instruments, yet they are used as if they are already proven to be valid. (Author/AM)

Data on the concurrent validity of the McCarthy Scales, using two Wechsler Scales for Children as criteria, were compared with those of previous studies. Significant moderate to strong correlations at preschool and school-age levels between the General Cognitive Index of the McCarthy and Wechsler IQ's were noted. (Author/RD)

AN INVESTIGATION OF THE VALIDITY OF INTELLIGENCE AND OTHER TESTS USED IN THE DIAGNOSIS OF RETARDED CHILDREN WAS PERFORMED. EXPERIMENTAL SAMPLES CONSISTED OF 101 CHILDREN SELECTED FROM SPECIAL CLASSES FOR EDUCABLE MENTALLY RETARDED (EMR) WHOSE AGES RANGED FROM 6.9 TO 10 YEARS AND WHOSE IQ SCORES RANGED FROM 50 TO 80. THE TESTS EVALUATED WERE (1)…

Infant intelligence from birth until the age of two was measured to determine the usefulness of infant intelligence tests. Twenty infants were tested regularly over the two-year period. Results showed neither simplex nor other long-term patterns of interrelationship among the infant intelligence scores obtained. The study concludes that the…

The capability of the Slosson Intelligence Test and the Otis Lennon Mental Ability Test to predict academic achievement as measured by the Stanford Achievement Test is examined. The results indicated that the Slosson and Otis-Lennon significantly predict Stanford Vocabulary, Reading Comprehension, and Mathematical Concepts subtest scores.…

Examines the relationship between the Woodcock Word Comprehension Test and several measures of reading achievement and verbal intelligence on 194 children. Pearson product-moment correlations (r) were used to test the relationships. It appeared that the Woodcock Word Comprehension Test assesses reading ability more than general verbal ability.…

The results of this study indicate that the WISC-R IQs are good predictors of achievement. They predict general achievement as represented by the PIAT total score and achievement in specific areas including reading recognition, mathematics, and spelling as measured by the PIAT. (Author)

Compared were subtest scores and full scale results on the Wechsler Intelligence Scale for Children of 197 retarded (IQ 30-69) 7-to 15-year-old children. (CL)

We evaluated the predictive accuracy of short forms of the Wechsler intelligence scales for individuals with high functioning autism. Several short forms were derived from participants who had received the full procedure. Stepwise multiple regression analyses were performed to determine the strength of association between the subtests included in…

On test AH6 AG, the total score can be broken down into a verbal and a numerical-plus-diagrammatic subscore; results showed the test to be a good predictor of all-round scholastic ability. (Authors/SP)
