The Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Stanford‐Binet Intelligence Scale–Fourth Edition (SB‐IV), were administered to 20 gifted children and 20 non‐gifted children to examine the extent of the difference in IQ scores obtained on the two tests and whether order effects were present. Results show that the SB‐IV Composite Score was significantly higher than the WISC‐III Full Scale IQ for both groups. However, for the gifted group, unlike the non‐gifted group, this difference achieved significance only when the SB‐IV was administered first. When either IQ test was administered to the gifted students for the first time, without the confound of a learning influence, there was no significant difference in mean scores. However, when both tests were administered, it was found that the SB‐IV influenced the WISC‐III Full Scale IQ in a downward direction whereas the WISC‐III influenced the SB‐IV Composite Score in an upward direction. © 2002 Wiley Periodicals, Inc.  相似文献

This study examined the accuracy of three shortened measures of intelligence: the Woodcock–Johnson Tests of Cognitive Ability, Third Edition Brief Intellectual Ability (WJ III COG BIA) score; the Stanford–Binet Intelligence Scale, Fifth Edition Abbreviated IQ (SB5 ABIQ); and the Kaufman Brief Intelligence Test IQ Composite (K‐BIT) in predicting giftedness as assessed by the SB5 Full Scale IQ score (SB5 FSIQ). Participants were 202 third grade students who were individually administered the SB5, WJ III, and K‐BIT. Four scores (SB5 ABIQ, K‐BIT, WJ III COG BIA, and SB5 FSIQ) were extracted. Correlational analyses revealed positive, significant relationships among the four scores. Discriminant function analyses, conducted to examine the accuracy of the three shortened measures of intelligence in predicting giftedness, revealed that overall, the WJ III score was the most accurate, and the K‐BIT score was the least accurate in identifying giftedness. © 2008 Wiley Periodicals, Inc.  相似文献

This study investigated patterns of WISC‐III IQ subtest scores for gifted children. Subtest scatter of WISC‐III scores occurred with greater frequency in a gifted sample than for subjects reported in the test manual's normative sample. Variability from the subtest mean of the gifted was most evident on Similarities, Comprehension, Coding, and Symbol Search. The extent of subtest scatter and its pattern on the WISC‐III was similar to typical patterns of highs and lows found for gifted children on the WISC‐R with one notable exception. There was a marked lack of strength in Block Design, previously seen as a peak subtest for gifted students when assessed with the WISC‐R.  相似文献

This study examined the concurrent validity of the Slosson Full‐Range Intelligence Test (S‐FRIT) by comparing S‐FRIT scores to the scores of the Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Woodcock‐Johnson Tests of Achievement–Revised (WJ‐R). Data from 123 elementary students' screening and psychological testing results were examined. Results revealed that the S‐FRIT scores were more related to overall intelligence, verbal, and math abilities than nonverbal intelligence, reading, or written language abilities. Further, it was found that 89% of the participants' S‐FRIT Full‐Range IQ scores fell within one standard deviation of their WISC‐III FSIQ scores, with an average discrepancy of 7.6 points. Discrepancies between S‐FRIT and WISC‐III scores were also examined by educational diagnostic categories and ability levels. Limitations and suggestions for future research are provided. © 2002 John Wiley & Sons, Inc.  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.

Regrouping Wechsler Intelligence Scale for Children‐Third Edition (WISC‐III) subtests into Bannatyne's spatial, conceptual, and sequential patterns has been thought by many to identify children with learning disabilities (LD). This study investigated the prevalence and diagnostic utility of WISC‐III Bannatyne patterns by comparing 1,302 children with LD to 2,158 children in the WISC‐III normative sample. Further analysis was conducted on a subsample of students with specific reading disabilities. Results indicated that the presence of the Bannatyne WISC‐III pattern would not lead to decisions that are useful in differentiating children with LD from children without LD. For example, receiver operating characteristic (ROC) analysis, measured by the area under the curve (AUC), indicated that the Bannatyne WISC‐III pattern exhibited low diagnostic utility (AUC = 0.54–0.55). Due to its inaccuracy, use of the Bannatyne WISC‐III pattern is not recommended.  相似文献

High scores on the Adolescent‐School Problems (A‐Sch) content scale and the Immaturity (IMM) supplementary scale of the MMPI‐A have been associated with poor school performance and possible learning disabilities (Archer, 1997). The aim of the present study was to determine whether these scales were associated with cognitive performance as measured by the WISC‐III. Subjects completed the Wechsler Intelligence Scale for Children, Third Edition (WISC‐III) and the MMPI‐A. Their scores for the WISC‐III sub‐tests and SCAD were calculated. The A‐Sch content and the IMM supplementary scales were extracted from the MMPI‐A. The results indicated that A‐Sch was associated with lower WISC‐III scores in males and predicted poorer performance in Full Scale IQ (FIQ), Verbal IQ (VIQ), Information, and Arithmetic. For females however, there was little evidence to suggest a relationship between A‐Sch and cognitive performance. The association between IMM and the WISC‐III sub‐tests was found to be a result of its correlation with A‐Sch. The implications of these findings, in particular, those involving gender differences, were discussed. © 1999 John Wiley & Sons, Inc.  相似文献

The Dumont‐Faro short form was used to estimate Wechsler Intelligence Scales for Children‐III (WISC‐III) Full Scale IQ scores for 45 special education students in a rural setting. Using the validation criteria proposed by Resnick and Entin (1971), results demonstrated that IQ scores generated by the Dumont‐Faro short form were positively correlated (r= .96) with the WISC‐III Full Scale scores. A significant mean difference in scores and an IQ misclassification rate of 44%, however, challenge the utility of the Dumont‐Faro short form for estimating WISC‐III Full Scale IQ. © 2001 John Wiley & Sons, Inc.  相似文献

If the factor structure of a test does not hold over time (i.e., is not invariant), then longitudinal comparisons of standing on the test are not meaningful. In the case of the Wechsler Intelligence Scale for Children‐Third Edition (WISC‐III), it is crucial that it exhibit longitudinal factorial invariance because it is widely used in high‐stakes special education eligibility decisions. Accordingly, the present study analyzed the longitudinal factor structure of the WISC‐III for both configural and metric invariance with a group of 177 students with disabilities tested, on average, 2.8 years apart. Equivalent factor loadings, factor variances, and factor covariances across the retest interval provided evidence of configural and metric invariance. It was concluded that the WISC‐III was measuring the same constructs with equal fidelity across time which allows unequivocal interpretation of score differences as reflecting changes in underlying latent constructs rather than variations in the measurement operation itself. © 2001 John Wiley & Sons, Inc.  相似文献

The Processing Speed Index (PSI) was first introduced on the Wechsler Intelligence Scale, Third Edition (WISC‐III; D. Wechsler, 1991), and little is known about its clinical significance. In a referred sample (N = 980), children with neurological disorders (ADHD, autism, bipolar disorder, and LD) had mean PSI and Freedom from Distractibility Index (FDI) scores that were below the group mean IQ and lower than Verbal Comprehension (VCI) and Perceptual Organization (POI). For these groups, Coding was lower than Symbol Search. The majority of these children had learning, attention, writing, and processing speed weaknesses. This pattern was not found in the other clinical groups. For children with depression, only PSI was low. Children with anxiety disorders, oppositional‐defiant disorder, and mental retardation had no PSI weakness. PSI and POI were both low in children with traumatic brain injury and spina bifida. Implications for a revision of the WISC‐III (WISC‐IV; D. Wechsler, 2003) are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 333–343, 2005.  相似文献

This study examined the underlying constructs measured by the Woodcock‐Johnson Tests of Cognitive Abilities, Third Edition (WJ‐III COG) and the Stanford‐Binet Intelligence Scales, Fifth Edition (SB5), based on the Cattell‐Horn‐Carrol (CHC) theory of cognitive abilities. This study reports the results of the first joint confirmatory factor analysis of the WJ‐III COG and SB5 with an independently collected preschool‐aged sample. The WJ‐III COG and SB5 were administered to 200 preschool‐aged children of 4 to 5 with no known disorders or disabilities. Confirmatory factor analyses using maximum likelihood estimation were conducted to evaluate three models of increasing complexity and two alternative models to determine which model best describe the underlying constructs measured by the WJ‐III COG and the SB5. Though none of the models displayed a good fit to the data, results showed that the underlying construct of the two tests was best represented by a Three‐Stratum alternative CHC model in which the Gf factor and subtests were omitted. Exploratory factor analysis was conducted to provide further insights into the actual latent structure underlying the data. Implications of findings to guide school‐based practitioners in using cross‐battery assessment with preschool children were addressed.  相似文献

A national survey investigating the use of dynamic assessment and other nontraditional assessment techniques among school psychologists (N = 226) was conducted. Results of the survey indicated that 42% of respondents were at least “somewhat familiar” with dynamic assessment. However, of those familiar with dynamic assessment, only 39% reported using the techniques once a year or more. The most frequently endorsed reasons for not using dynamic assessment (if familiar with it) were lack of knowledge and time restraints. Learning disabled students were the population of students most often evaluated using dynamic assessment and the dynamic assessment was most often used to determine processing strengths and weaknesses. The majority of those familiar with dynamic assessment became so through independent reading. Only 10% reported learning about dynamic assessment through course work. In response to questions regarding assessment techniques most often used with minority students the majority of respondents reported using traditional assessment tools including the WISC‐III (Wechsler Intelligence Scale for Children–Third Edition), BINET IV (Stanford‐Binet Intelligence Scale–Fourth Edition), or KABC (Kaufman Assessment Battery for Children). Overall, the results of the survey suggest that although the population is becoming increasingly more diverse and changes in PL94‐142 (Public Law 94‐142) demand functional assessments, school psychologists continue to rely heavily upon traditional assessment techniques to address referral concerns of all students. This may in large part be due to weaknesses in graduate training programs. © 1999 John Wiley & Sons, Inc.  相似文献

The Native American population is severely underrepresented in empirical test validity research despite being overrepresented in special education programs and at increased risk for psychoeducational evaluation. The structural validity of the Wechsler Intelligence Scale for Children – Fourth Edition (WISC‐IV) was investigated with a sample of 176, six‐to‐sixteen‐year‐old Native American children referred for a psychoeducational evaluation. Confirmatory factor analysis procedures replicated the normative first‐order factor structure and a higher‐order general ability factor that accounted for the greatest amount of common (69%) and total (33%) variance. These results support the structural validity of the WISC‐IV with a referred Native American sample and suggest that interpretation of the WISC‐IV scores should not neglect the strong general ability factor.  相似文献

The Stanford–Binet Intelligence Scale, Fifth Edition (SB5), is a recently published, multidimensional measure of intelligence based on Cattell–Horn–Carroll (CHC) theory. The author of the test provides results from confirmatory factor analyses in the technical manual supporting the five‐factor structure of the instrument. Other authors have examined this factor structure through EFA using the standardization sample, and have not found evidence of a five‐factor model. The purpose of the current study was to examine the internal construct validity of the SB5 using an independent sample of high‐functioning students. Participants included 201 high‐functioning, third‐grade students ranging in age from 8 years, 4 months to 10 years, 11 months. Five models of the SB5 were analyzed using Analysis of Moment Structures (AMOS). Our findings indicated that a hierarchical, four‐factor, post‐hoc model provided the best fit to the data. Generally, implications for school psychologists include a better understanding of the factor structure of the SB5, especially as it relates to high‐achieving children. Directions for future research are also discussed. © 2010 Wiley Periodicals, Inc.  相似文献

This study examined the concurrent validity of the General Ability Measure for Adults (GAMA1; Naglieri & Bardos, 1997) and the Wechsler Adult Intelligence Scale‐Third Edition (WAIS‐III; Wechsler, 1997). Sixty college students were administered both instruments in counterbalanced order. A comparison of the mean scores on the GAMA and WAIS‐III indicated that the sample obtained similar GAMA and WAIS‐III PIQ scores. In contrast, the sample's mean GAMA IQ score was significantly lower than the sample's mean FSIQ and VIQ scores. Although the GAMA IQ score was positively correlated with all WAIS‐III IQ and Index scores, this new instrument was more clearly associated with visual‐spatial reasoning, as defined by the WAIS‐III PIQ. The GAMA's accuracy in predicting performance on the WAIS‐III FSIQ and PIQ also was examined, with the GAMA underestimating WAIS‐III FSIQ and PIQ scores for participants falling within the Superior and Very Superior range of intellectual functioning. © 2001 John Wiley & Sons, Inc.  相似文献

This article focuses on the attitudes of intellectually gifted students toward school. The average WISC‐R IQ was 127, the average Stanford Binet was 140. The School Attitude Measure (SAM) was administered to 119 students, grades four through nine, participating in an enrichment program. The SAM scores for this group of students were well above average; most were significantly higher than the standardization sample. The results are discussed.  相似文献

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

Current research on the use of revisions of intelligence measures with ethnically diverse populations and younger children is limited. The present study investigated the utility of the Stanford–Binet Intelligence Scales, Fifth Edition (SB5), with an ethnically diverse preschool sample. African American and Caucasian preschoolers, matched on age, gender, and parental education, were found to have similar patterns of high and low scores on both the composites and all subtests of the SB5. The present study also found that African American and Caucasian preschool children did not differ on overall cognitive ability as measured by the SB5 Full Scale IQ. Implications and suggestions for further research are discussed.  相似文献

This study examined the factor structure of the Wechsler Intelligence Scale for Children‐Fifth Edition (WISC‐V) with four standardization sample age groups (6–8, 9–11, 12–14, 15–16 years) using exploratory factor analysis (EFA), multiple factor extraction criteria, and hierarchical EFA not included in the WISC‐V Technical and Interpretation Manual. Factor extraction criteria suggested that one to four factors might be sufficient despite the publisher‐promoted, five‐factor solution. Forced extraction of five factors resulted in only one WISC‐V subtest obtaining a salient pattern coefficient on the fifth factor in all four groups, rendering it inadequate. Evidence did not support the publisher's desire to split Perceptual Reasoning into separate Visual Spatial and Fluid Reasoning dimensions. Results indicated that most WISC‐V subtests were properly associated with the four theoretically oriented first‐order factors resembling the WISC‐IV, the g factor accounted for large portions of total and common variance, and the four first‐order group factors accounted for small portions of total and common variance. Results were consistent with EFA of the WISC‐V total standardization sample.  相似文献

Abstract

To 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
