The K-BIT and the WISC-R were administered in counterbalanced order to 35 referred students. Although the K-BIT IQ Composite correlated significantly with the WISC-R Full Scale IQ scores (r=.81), the mean scores differed significantly (difference = 6.2 points; p<.001). The results provide moderate support for the K-BIT as a screening instrument when the WISC-R is the follow-up or comprehensive measure of intelligence. 相似文献

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R were compared in two samples of children. In the first sample, there were 34 black and 27 white rural Southeastern Alabama children being considered for special education classes. In the second sample, there were 4 black and 81 white suburban Alabama children being considered for classes for the talented and gifted. In both samples, correlations between the SIT IQ and WISC-R Full Scale IQ were significant (rs of .70 and .48, respectively). However, in the special education sample, SIT IQs were significantly higher than WISC-R Full Scale IQs by about 7 points. The results from both samples provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the IQs on the two tests may not be interchangeable. 相似文献

The Peabody Picture Vocabulary Test (PPVT), Form A was compared to the Wechsler Intelligence Scale for Children-Revised (WISC-R) in two samples of children with reading disabilities. One group of 14 children, referred to a university clinic, were administered the WISC-R, followed by the PPVT. The second group of 38 children from a private learning disability center were administered the PPVT first, followed by the WISC-R. In the combined sample, the PPVT IQ (X̄ = 109.2) was significantly higher than the WISC-R Verbal IQ (X̄ = 98.9), Performance IQ (X̄ = 97.0), and Full Scale IQ (X̄ = 97.5). Similarly, the PPVT IQ was significantly higher than the WISC-R Full Scale in both samples separately, regardless of which test was administered first. In one case, the PPVT IQ was 50 points higher than the WISC-R IQ. Correlations between the PPVT and WISC-R Verbal, Performance, and Full Scale IQs were significant (rs = .56, .29, and .50, respectively). The results suggest that the two tests do not provide interchangeable IQs for a population of reading disabled children. 相似文献

The WISC-R and the Slosson Intelligence Test (SIT) were given to 69 randomly selected children in grades one through six in an urban school system. A regression equation for predicting WISC-R full scale IQ from SIT was developed. Previous studies had reported that SIT IQs tended to be consistently higher than WISC-R IQs. The present study revealed that SIT IQs were considerably higher than WISC-R IQs in the upper range and slightly lower in the lower range. A possible reason for the discrepancy is that the present study used a normal population and previous studies used restricted ranges. It was concluded that the SIT provides a good estimate of WISC-R full scale IQs when a regression equation is used. It was recommended, however, that educational placement decisions should not be made on the basis of any single IQ measure. 相似文献

Twenty urban EMR students' WISC-R scores were compared with their previously administered WISC scores. The average interval between administrations was approximately three years. Significant coefficients of correlation were obtained between five corresponding subtests and between Performance IQs and Full Scale IQs. Results from t tests for correlated data indicated that mean WISC-R Verbal, Performance, and Full Scale IQ scores were not significantly lower than their corresponding WISC scores. The results of this study indicated that WISC-R scores in comparison to WISC scores appeared to be more stable in the lower IQ ranges and less vulnerable to cultural bias. 相似文献

Forty-seven talented fourth graders were assessed on different WISC-R short-form combinations in order to determine which short-form was the most effective predictor of high Full Scale WISC-R IQ. The short-form combinations of Similarities + Object Assembly + Vocabulary subtests (SI-OA-VO) or Similarities + Object Assembly subtests (SI-OA) were more effective in this regard than eight other WISC-R short-form combinations, the Slosson Intelligence Test, and school grades in Math, Language, and Reading combined. The findings are of relevance to gifted assessment. 相似文献

Children who had been nominated as potential candidates for gifted programs were assessed to determine the relationships among certain behavioral and intellectual characteristics. Records were compiled listing 132 first- through eighth-grade children's race, sex, age, grade level, Slosson Intelligence Test (SIT) IQ scores, Scale for Rating Behavioral Characteristics of Superior Students (SRBCSS) scores, and WISC-R IQs. Only children achieving SIT IQs of 130 or higher were included. A regression equation for the prediction of a WISC-R Full Scale IQ score from a given SIT score was computed and compared to that developed for predicting the WISC-R IQ in another study. All variables except SIT IQ were poor predictors of WISC-R IQ scores. A moderate correlation was computed between SIT and WISC-R Verbal and Full Scale IQ scores. A somewhat lower, but still significant, degree of relationship was found between SIT and WISC-R Performance IQ scores. Some difficulties with using the SIT as a screen for gifted programs are discussed. 相似文献

The relationship between the WISC-R and WAIS-R was studied in a sample of 30 special education children (22 male and 8 female). Children were administered the WISC-R at an average age of 13.85 years and the WAIS-R at an average age of 17.52 years. ANOVAs indicated that the two tests yielded Verbal, Performance, and Full Scale IQS that were not significantly different. For example, the mean Full Scale IQ was 81.13 for the WISC-R and 82.70 for the WAIS-R. Product-moment correlations also were highly significant, with rs ranging from .76 to .86 for the three scales. The results suggest that, for children of limited intelligence, the WISC-R and WAIS-R provide comparable IQs over a four-year time period. 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

Correlations between the WISC-R Full, Verbal, Performance, and Freedom from Distractibility Scale IQs, WISC-R subtest scaled scores, and Wide Range Achievement Test Reading, Spelling, and Arithmetic standard scores were computed for a sample of 114 children (64 boys, 50 girls), aged 6 to 16 years, who were referred for psychological evaluation because of academic or learning difficulties. The Full Scale IQ, Verbal Scale IQ, and Freedom from Distractibility IQ correlated moderately with the three achievement area standard scores (rs of .48 to .59). However, the Performance Scale IQ correlated minimally with reading and spelling scores (rs of .26 and .27), but moderately with arithmetic scores (r = .40). The results support the concurrent validity of the WISC-R. 相似文献

This study investigated the performance of 166 special education students who had been administered the WISC-R and approximately 3 years later the WISC-III. The sample ranged in age from 6.0 to 16.6 years. The scores were analyzed using Pearson product moment correlation coefficients and t tests of the differences between means for related samples. The results indicated that there was a significant, positive correlation among global scales (p < .001). This finding suggests that the WISC-R and the WISC-III IQ scores measure similar abilities. Analysis of mean IQ score differences revealed significant differences in the WISC-R and the WISC-III IQ scores, with the WISC-III global scores being lower. Implications for the evaluation of students for special education are discussed, with special emphasis on the role and function of the psychologist practicing in the schools. © 1996 John Wiley & Sons, Inc. 相似文献

This study investigated the best short form version of the WISC-R for learning disabled (LD) students. The WISC-R was administered to 234 LD and 290 children who were referred for psychological evaluation but were found not eligible (NE) for special education services from 45 school districts in Michigan. Stepwise multiple regressions were calculated to ascertain the best tetrads of Full Scale IQ (FS IQ) for the two groups. For the NE sample, Vocabulary, Picture Arrangement, Picture Completion, and Information were the best four indicators of FS IQ, accounting for about 80% of the variance in Full Scale scores. For the LD sample, the best four predictors of FS IQ were Similarities, Block Design, Picture Completion, and Vocabulary, accounting for about 80% of criterion variance. Using the WISC-R standardization data, Sattler identified the Information, Vocabulary, Comprehension, and Block Design subtests as one of the best short form versions for predicting FS IQ. For the LD sample of the present study, Sattler's composite yielded a multiple R of .873 with FS IQ, whereas our best four predictors yielded a multiple R of .896. It appears that Sattler's tetrad is about as good a predictor of FS IQ for LD students as that found in the present data. 相似文献

The purpose of this study was to determine the degree of comparability between the WISC and the WISC-R over time. Hypotheses were tested using a sample of 276 mildly mentally handicapped children enrolled in special education classes who had received a WISC (Trial 1) and a WISC or WISC-R (Trial 2) after an interval of approximately three years. The sample was grouped on the basis of test administered in Trial 2. Group I contained those children who received the WISC on Trial 2 and included 183 children, of whom 121 were males and 62 were females. Mean age at time of initial testing was 8–10; mean age at second testing was 11–8. Group II was composed of 93 children who had been posttested on the WISC-R and included 72 males and 21 females. Mean age at initial testing was 9–5; mean age at posttest was 13–0. The study was conducted in five school districts and one county department of education. Verbal IQ, Performance IQ, and Full Scale IQ for both instruments administered were transcribed from the special education folders of the children. The design used to test hypotheses was repeated measures analysis of variance. Data analysis resulted in rejection of the hypotheses that the WISC-R yields mean Verbal, Performance, and Full Scale IQ scores greater than or equal to the corresponding mean IQ scores of the WISC. It was concluded that the WISC-R may unfairly penalize special education children who are reevaluated with this instrument. Fluctuations in IQ scores due to the instrument of measurement must be recognized, and appropriate action should be taken to insure that children are evaluated for special class placement on comparable bases. 相似文献

Eighty public school children referred for psychological assessment for potential special education placement were given the Slosson Intelligence Test, Peabody Picture Vocabulary Test, Developmental Test of Visual-Motor Integration, and Wechsler Intelligence Scale for Children—Revised. Correlational and regression techniques were used to determine the effectiveness of the three former measures in predicting WISC-R IQ scores. SIT IQs were found to be the best predictors of WISC-R Verbal, Performance, and Full Scale IQs; however, these statistical relationships reveal little about the clinical utility of the screening measures. Problems with use of the current findings and those of other studies are discussed. 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

Twenty-five white children in the bright normal range of intelligence were administered both the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scale for Children-Revised (WISC-R). The mean values for the normally obtained mental age (MA) and adjusted MA were then compared to the mean WISC-R test age (TA). The normally obtained Stanford-Binet MA and the WISC-R TA values were nearly identical. However, the adjusted values for the Stanford-Binet MA were found to be significantly lower (p<.05) than the WISC-R TA. The findings failed to support the common practice of computing an adjusted MA score. 相似文献

Results of the TONI, WISC-R, and WRAT were compared for a sample of 66 learning disabled children: 51 males (32 white, 19 black) and 15 females (9 white, 6 black) whose mean age was 9–5 (SD = 1–10). The mean score of the TONI was significantly different from the Performance IQ. Nonsignificant differences were found between the TONI and Full Scale IQ and between the TONI and Verbal IQ. Correlation coefficients between the TONI and WISC-R ranged from a low of .35 for the Verbal IQ to .44 for both the Full Scale and Performance IQs. The correlation coefficients between the TONI and standard scores of the WRAT were .38, .27, and .23, for Reading, Spelling, and Arithmetic, respectively. Implications of these findings are discussed. 相似文献

Discrepancies between IQ and Index scores on the WISC-111 were investigated for a sample of students with SLD (n = 202), with MR (n = 115), and evaluated but not classified (n=159). Mean Verbal and Performance IQ discrepancies, though significantly different for each sample, were smaller than those reported in the WISC-III manual for the normative sample. Similarly, the Index score comparisons indicated differential functioning for the three samples, with the exception of the Verbal Comprehension and Freedom from Distractibility Index discrepancy. Moreover, the Performance IQ was higher than the Verbal IQ for all three samples. Consistent with the WISC-R literature, discrepancies between Verbal and Performance IQs and higher Performance than Verbal IQs are not diagnostic indicators of abnormalities. 相似文献

The System of Multicultural Pluralistic Assessment (SOMPA) was initially administered to 700 Anglo, 700 Black, and 700 Hispanic children in California elementary schools in order to develop a nonbiased testing program. Ten years later, 1184 of the original 2100 youths were again tested with the SOMPA in high school. At that time, academic achievement and parental interview data also were collected. The results indicate that: (a) Mean achievement test scores and GPAs for the high school students showed that Anglos obtained higher scores than Hispanics, who received higher scores than Blacks. (b) Among the various medical measures, the Bender Gestalt, Fine Motor Sequencing and Finger-Tongue Dexterity tests of the SOMPA were the only ones able to consistently differentiate between youth who did poorly and those who did well academically ten years after their initial testing. (c) Scores on the 1972 IQ test (WISC-R) showed moderate correlations with achievement test scores ten years later. (d) 1972 IQ scores showed low but reliable correlations with GPAs ten years later. (e) In only a very few instances were IQ correlations with achievement test scores higher for minorities than for Anglos. (f) IQ correlated less well with GPA than with achievement test scores for all three ethnic groups. (g) An adjusted IQ, called Estimated Learning Potential (ELP), was more predictive of school achievement than was verbal IQ, particularly for Blacks in the lowest sociocultural quartile. (h) In the second lowest sociocultural quartile, the VIQ correlations with academic measures were reliably higher than the VIQ-ELP correlations, but only for the Anglo and total groups. (i) In the upper two sociocultural quartiles, for all ethnic groups combined, VIQ correlated slightly, but significantly, higher than ELP with school achievement. (j) Also in the upper two quartiles, VIQ correlated higher with academic measures than did VIQ-ELP for both Blacks and Hispanics in almost half of the comparisons. In conclusion, it appears that some subtests of the SOMPA may have some validity for predicting school achievement for students from different ethnic groups. 相似文献

This study was undertaken to determine the suitability of the California Abbreviated WISC—Form 1 (CAW-1) for use with WISC-R subtests. Subjects were drawn from the files of previously evaluated students from two southern mountain communities. Examination of WISC records within the age and IQ ranges of the CAW-1 (CA 8-0 to 13-6, IQ 50 to 80) indicated that our sample was not significantly different from the CAW-1 noim group (N = 148, r = .85 between CAW-1 & WISC Full Scale IQ). WISC-R recods (N = 178) for the same ranges were examined and were found to be more highly predictive of Full Scale IQs (r = .91, FSIQ = .98 CAWIQ + 2.2). Extensions of the age range from 6-0 to 16-11 and of the IQ range from 40 to 100 were attempted. Final results (N = 284) indicated the CAW-1 could be used with the WISC-R over the full age range and for IQs ⩽ 100 with minor alteration (r = .96, FSIQ = 1.09 CAWIQ - 5.4). The second sample served for cross validation of these results. Using the alteration, results were consistent with original findings (N = 202, r = .93, FSIQ = .98 CAWIQ + 2.2). It was concluded that the CAW-1 was suitable for use with WISC-R subtests with minor alterations. 相似文献
