The comparability of the Test of Cognitive Skills (TCS) with the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) with 75 elementary- and middle-school-aged gifted students was investigated. Results indicated that the mean Cognitive Skills Index was about 6 points higher than the WISC-R FSIQ and about 9 points higher than the SBIV Composite score. Correlation coefficients between the TCS Cognitive Skills Index and the SBIV Composite score and the WISC-R FSIQ were.51 and.41, respectively. Absolute differences between individual scores revealed that 44% of the students' SBIV Composite scores were more than 10 points different than their Cognitive Skills Index, and 28% of the students' WISC-R FSIQ scores were more than 10 points different. The results indicated limited comparability between the TCS and WISC-R and SBIV. The implications of these findings and future research questions are discussed. 相似文献

Each year thousands of children are evaluated or reevaluated utilizing the current edition of the Wechsler Intelligence Scale to determine their eligibility for gifted programs. The Wechsler Intelligence Scale for Children-III (1991) is new enough that only limited research is available on how it compares to the previously used Wechsler Intelligence Scale for Children-Revised (1974). The purpose of this study was to determine the comparability between the previously dominant intelligence scale, the WISC-R, and the revised WISC-III with gifted children. The results of this study indicate that the latest revision (WISC-III) and the earlier version (WISC-R) produce remarkably similar scale and subtest scores when administered under clinical conditions to gifted children. All 51 children determined eligible through the administration of one of these two Wechsler tests would have been eligible for services had the other test been administered. The Verbal and Performance scale IQ scores were within two points of each other across the two test administrations, while only a one-point difference existed between the Full Scale IQ scores. The Arithmetic, Comprehension, and Object Assembly subtest scores were in high agreement across the two administrations (p<.01). The level of agreement between some subtests across the two administrations suggests that clinical judgment is just as important as scores in considering who is eligible for gifted programs. 相似文献

Adolescents (n=43) previously diagnosed as dyslexic/reading disabled had markedly lower IQ scores on the newly standardized Wechsler Intelligence Scale for Children (WISC-III) than on the earlier administered WISC-R. The declines for Verbal, Performance, and Full Scale IQs were 10, 12, and 11 points, respectively, which were twice as great as in a subset of the standardization sample given both versions of the WISC. The adolescents did not show a significant decline in standard scores from the Wide Range Achievement Test (Level I to Level II). However, only two subjects had current reading and spelling standard scores above the 25th percentile. The impact of lower WISC-III IQs on guidelines for classification of students as learning disabled is discussed. 相似文献

The Wechsler Intelligence Scale for Children-Revised (WISC-R) was administered to 56 learning disabled children, using standard assessment procedures and format as outlined by Wechsler. Abbreviated IQ scores were then derived by applying the Kennedy-Elder formula, and equation that uses five WISC-R subtests with varied weightings. Comparisons between the standard IQ scores and the abbreviated IQ scores were evaluated. A Pearson product-moment correlation coefficient of .83 and a non-significant t-test between the mean IQs suggested the two scores were interchangeable. However, frequent IQ classification changes (23%) rendered the K-E format unacceptable for this population. 相似文献

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) and the Kaufman Test of Educational Achievement (K-TEA; Kaufman & Kaufman, 1985) are commonly used in the identification of children for special educational services. However, there is little evidence about the relationship between these two tests among children with handicapping conditions. This study examined the relationship between the WISC-III IQs and K-TEA standard scores in a sample of 72 children with emotional handicaps. The results revealed a significant positive relationship between scores on these instruments. © 1996 John Wiley & Sons, Inc. 相似文献

Standard Age Scores on the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and WISC-R IQs of 51 urban black males receiving special education services were compared. Correlations between the SBIV Composite scores and WISC-R Verbal, Performance, and Full Scale IQs were 0.803, 0.826, and 0.87 respectively. Correlations between all combinations of scales ranged from 0.612 to 0.888, median r=.723. SBIV Composite mean scores did not differ significantly from the mean WISC-R Full Scale, Verbal, and Performance IQs. Regression analysis of the three subgroups (BD. LD, and EMR) indicated that the SBIV possesses differential validity for each group. Tabular comparison of precision of classification between the SBIV and the WISC-R yielded a 78% agreement. These data suggest that the SBIV possesses utility for assessing the intelligence of black students classified as BD and EMR. However, the use of the scale with LD students is unsupported. 相似文献

The present investigation compared the Cognitive Levels Test (CLT) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 55 children who were referred for remedial educational services. A comparison of the correlations for each of the criterion measures from the WISC-R showed a consistent significant positive relationship with the CLT. A repeated measures analysis of variance that compared standard scores for the CLT with those of the WISC-R indicated that significant differences existed between WISC-R IQs and the CLT Cognitive Index. Implications concerning the validity of the Cognitive Levels Test are discussed. 相似文献

The transition of adults with learning disabilities to successful employment is contingent upon numerous factors. Eighty-six adults (55 males and 31 females), 18 to 59 years old (mean age 26.7 years), with learning disabilities were evaluated clinically using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) (Wechsler, 1981) to determine the value of WAIS-R IQs and subtest scores in predicting successful employment. Significant relationships were identified between subjects' WAIS-R IQs and scaled scores and job success. Conclusions and recommendations were reported. 相似文献

This study compares three different measures of intelligence used with preschool children identified “at-risk.” Seventy preschoolers were administered the Wechsler Preschool and Primary Scale of Intelligence, Peabody Picture Vocabulary Test-Revised, and the Expressive One-Word Picture Vocabulary Test. The sample consisted of 21 girls and 49 boys, of which there were 30% Orientals, 3% White, 20% Black, and 7% Native Americans. Pearson's product-moment correlation was used to analyze the data. Correlated t-tests were used to calculate the differences between the mean IQs for the tests. The PPVT-R and EOWPVT were found to be significantly correlated with the Verbal and Full Scale IQ scores of the WPPSI. In addition, the PPVT-R and EOWPVT correlated significantly with the Performance Scale IQ of the WPPSI. The results and their implication for the assessment of preschool children are discussed. 相似文献

The personality and intellectual characteristics of three groups of children, one molested by a teacher (n = 16), a second group (n = 16) where the offender was a member of the child's family, and a non-molested control group (n = 16) were contrasted. The children were evaluated using the Personality Inventory for Children (PIC), the Children's Personality Questionnaire (CPQ), and the Wechsler Intelligence Scale for Children (WISC-R). There were few differences between the two molested groups or between boys and girls. However, comparisons of molested and non-molested children showed significant differences on 23 of 34 scales on the PIC and CPQ combined. WISC-R verbal IQs were also lower for the molested groups. While the lack of differences between the two molested groups may have been due to the parent-like relationship between the teacher and the children he molested, the results suggest that a relatively noncoercive style of abuse can still produce significant psychological impairment. 相似文献

The Kaufman Assessment Battery for Children (K-ABC) purports to assess fluid and crystallized intelligence via processing and achievement subtests, respectively. Eight K-ABC Mental Processing and five K-ABC Achievement subtests were administered to 41 gifted students. Scores were subsequently compared to concurrent achievement measures from the California Achievement Test (CAT), as well as previously obtained mental ability measures (Wechsler Intelligence Scale for Children-Revised [WISC-R], Stanford-Binet [SB], and Wide Range Achievement Test [WRAT] achievement scores). In general, K-ABC mental ability scores were lower than WISC-R and SB IQs. K-ABC achievement scores were consistent with K-ABC mental ability scores, but more highly related to SB and WISC-R VIQ (r = .42 and .40, respectively) than to WISC-R FSIQ (r = .16) and PIQ (r = .09), or to the K-ABC Mental Processing (Composite r = .17), Simultaneous Processing (r = .08), and Sequential Processing scores (r = .20). With the exception of WRAT Word Recognition, WRAT, K-ABC, and CAT achievement scores were similar. The patterns of intercorrelations suggest that the K-ABC achievement scores are more verbally loaded than are the CAT and WRAT achievement measures. 相似文献

The Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) are two tests that are often used in the assessment process for special education referrals. Sex differences apparent in these tests were examined in a sample of Arkansas school children who were first-time referrals for a psychological evaluation. The subjects' PPVT-R standard scores, WISC-R IQ scores, and WISC-R subtest scores were divided into groups according to one-year intervals from ages 6 through 16. A separate 2 × 11 (subjects' sex x subjects' age) analysis of variance was performed for each dependent variable. Results indicated significant sex differences among WISC-R Full Scale, Verbal, and Performance IQs and PPVT-R standard scores (p < .01). Several WISC-R subtests also revealed significant sex differences. Further significant sex differences were indicated at several age groups on each dependent variable, with males consistently scoring higher than females on 87%. of the dependent measures excluding the WISC-R subtest Coding, on which females scored higher. Implications concerning the referral process are discussed. 相似文献

Thirty learning disabled students of average intellectual ability between 16 and 17 years of age were given both the WISC-R and the WAIS-R to determine if the WAIS-R provided higher average IQ scores, as had been reported for educationally mentally retarded adolescents. The results indicated: (a) no significant differences between the two scales on either the Verbal, Performance, or Full Scale IQs, (b) significant correlations between the WISC-R and WAIS-R on the three IQ scores and 9 of the 11 subtests, and (c) the emergence of the ACID profile for learning disabled adolescents on both tests. 相似文献

AbstractTo examine the usefulness of the Slossen Intelligence Test (SIT) and the Quick Test (QT) with poor readers, the relative validities of the SIT and the QT were examined by comparison to the more comprehensive Wechsler Intelligence Scale for Children (WISC). Intercorrelations of fifty-six poor readers, scores on all three tests were obtained. SIT and WISC (Full Scale) IQ’s (r =. 60) were significantly more closely related than were QT (Total) and WISC (Full Scale) IQ’s (r = .49) although scores from both of the brief tests were significantly correlated with WISC scores. The results are discussed in terms of test characteristics, and implications are drawn in terms of purpose for testing. 相似文献

The purpose of this investigation was to determine whether or not attention-deficit/hyperactivity disorder (ADHD)-when there was an absence of reading problems-was associated with having a high IQ. The vocabulary and block design short forms of the Wechsler Intelligence Scale for Children-Third Edition were administered to 63 children with ADHD, 69 children with reading difficulties (RD), and 68 children with comorbid ADHD + RD. Results indicated that the distributions of estimated Full Scale IQs (FSIQ) for each of the three groups of children did not differ significantly from a normal distribution, with the majority of children (more than 50%) in each group scoring in the average range. The percentage of children with ADHD who scored in the above-average range for FSIQ was not significantly higher than the percentages of children in the other two groups. No significant group differences emerged for estimated FSIQ, vocabulary, or block design. It was concluded that children with ADHD are no more likely to have an above-average IQ than are other children. 相似文献

Reviews involving the Wechsler Scales for children suggest that Full Scale IQ scores on the Wechsler Intelligence Scale for Children, Third Edition, average 5 to 6 points lower than scores on the second edition of the scale [WISC‐R, Wechsler, D. (1974). Zimmerman & Woo‐Sam, 1997], with the differences distributed disproportionately over subtests, i.e., with larger discrepancies found within the Performance Scale (Wechsler, 1991). Changes on the revised subtests of the WISC‐III Performance Scale may place children with ADHD at a disadvantage compared to their performance on analogous WISC‐R subtests. We examined IQ test performance in 122 unmedicated children with ADHD (61 given the WISC‐R, 61 given the WISC‐III), and 46 children from a healthy, comparison group (23 given the WISC‐R, 23 given the WISC‐III). The ADHD and comparison group samples were matched for sex and for Verbal IQ between WISC‐R and WISC‐III. Children with ADHD had significantly lower Performance IQ on WISC‐III compared to the WISC‐R, with the Picture Arrangement subtest showing the most significant difference. In contrast, there were no significant differences between the WISC‐R and WISC‐III cohorts on Performance IQ or any Performance subtests among the comparison group. These findings highlight the importance of examining the comparability of ability test revisions among clinical and non‐clinical populations, and will be especially salient when the WISC‐III is revised. © 2003 Wiley Periodicals, Inc.

Concurrent validity of the Kaufman Brief Intelligence Test (K-BIT) with the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) was evaluated, as well as the K-BIT's accuracy as a predictor of WISC-III scores, in a sample of young children with reading disabilities. The two measures were administered to 65 children from Atlanta, Boston, and Toronto who ranged from 6-5 to 7-11 years of age at testing. Correlations between the verbal, nonverbal, and composite scales of the K-BIT and WISC-III were .60, .48, and .63, respectively. Mean K-BIT scores ranged from 1.2 to 5.0 points higher than the corresponding WISC-III scores. Standard errors of estimation ranged from 10.0 to 12.3 points. In individual cases, K-BIT scores can underestimate or overestimate WISC-III scores by as much as 25 points. Results suggest caution against using the K-BIT exclusively for placement and diagnostic purposes with young children with reading disabilities if IQ scores are required. 相似文献

WIAT subtest and composite predicted-achievement values based on WISC-III verbal and performance IQs
Critical values tables for determining significant differences between Wechsler IQs and WIAT subtests and composites based on a predicted-achievement method are provided in the WIAT manual for the Full Scale IQ and have been constructed recently for Verbal and Performance IQs (Flanagan & Alfonso, 1993). In order to use these tables, however, a predicted achievement score(s) is required. The process of calculating predicted-achievement scores is time-consuming and may result in errors, especially when more than one ability-achievement comparison is warranted. The present paper provides tables of WIAT subtest and composite predicted-achievement standard scores based on WISC-III Verbal and Performance IQs. These tables allow examiners to determine quickly ability-achievement discrepancies based on WISC-III Verbal or Performance IQs when they are used in conjunction with the critical values tables provided in our earlier article. These tables are most useful for the accurate assessment and diagnosis of learning disabilities. 相似文献

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided. 相似文献
