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

This study examined the concurrent validity of the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Kaufman Assessment Battery for Children (K-ABC) with 47 students referred for learning difficulties. A comparison of the correlations of each of the criterion measures from the K-ABC global scales showed a more substantial relationship between the PPVT-R standard score and the K-ABC Achievement scale than with other K-ABC scales. In an effort to further examine the relationship between the PPVT-R and the K-ABC, a stepwise multiple regression was calculated, with the standard scores of the K-ABC global scales serving as the predictor variables of the PPVT-R. This analysis indicated that the K-ABC Achievement global scale was the only significant predictor of the PPVT-R. Implications for practitioners were discussed. 相似文献

This study examined the stability of the Kaufman Assessment Battery for Children (K-ABC) for a sample of at-risk preschool children. Over a 9-month time interval, the stability coefficients (corrected for restriction in range) for the global scales of the K-ABC ranged from .78 to .88. The stability coefficients (corrected for restriction in range) for the K-ABC subtests ranged from .65 to .79. It was concluded that scores on the K-ABC for at-risk preschool children display adequate stability, but that the Simultaneous scale appears to be more amenable to change than either the Sequential or Achievement scales. 相似文献

Raw scores on the 16 K-ABC subtests and the total raw scores on the sequential and simultaneous processing scales and the achievement scale were correlated with age in months for two separate samples, each subdivided by race and sex: the K-ABC standardization sample (N = 2000) and an additional group of blacks and whites tested during the development of the K-ABC sociocultural norms (N = 615). Within each sample, the highest and lowest correlations from all race/sex groups were contrasted across all K-ABC subtests and scales. All correlations between age and raw scores were statistically significant (p ⩽ .05). No significant differences occurred in the magnitude of these relationships as a function of race/sex grouping, supporting the construct validity of the K-ABC as a developmental measure of children's aptitude and achievement for blacks, whites, Hispanics, males, and females. 相似文献

This study examined the concurrent validity of the composite and area scores of the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and the Mental Processing Composite and global scale scores of the Kaufman Assessment Battery for Children (K-ABC). The tenability of interpreting the SBIV using the fluid/crystallized model, as suggested by the authors, was also considered. The subjects were 30 Black, learning-disabled elementary school students. Results of a t test indicated that the Mental Processing Composite score of the K-ABC was significantly higher than the SBIV Composite score. Moderate to high correlations were obtained when SBIV composite and area scores were compared to K-ABC composite and scale scores, reflecting a positive relationship between the two tests. The measures of fluid abilities (K-ABC Composite score; SBIV Abstract/Visual Reasoning) were highly correlated. The results of a multiple regression analysis indicated a moderate degree of correlation among the measures of crystallized ability (K-ABC Achievement; SBIV Verbal Reasoning and Quantitative Reasoning). The findings of this study demonstrated adequate concurrent validity for the SBIV. In addition, the results provided limited support for describing test results utilizing the fluid/crystallized interpretation model. Further research is suggested in order to examine other validity issues, such as classification of special education students and the SBIV's relationship to other similar instruments. 相似文献

The basic question addressed in this study was whether the discrepancies found between the Mental Processing Composite (ability component) and the Achievement subtests of the Kaufman Assessment Battery for Children (K-ABC) corresponded with the discrepancies found between the WISC-R Full Scale IQ and the PIAT subtests, or whether use of the K-ABC over the WISC-R and PIAT results in the identification of different students. The differences were evaluated using four standard score procedures for calculating a severe discrepancy. It was found that the K-ABC and WISC-R/PIAT approaches to the determination of a score difference resulted in the identification of different populations of students. The high average PIAT standard scores together with the lower subtest reliabilities appeared to be the primary source of disparity between the K-ABC and WISC-R/PIAT comparisons. 相似文献

Previous factor analyses of the K-ABC for school-age children have offered varying degrees of support for the test, depending on which subtests have been analyzed. Further, most previous analyses have involved only children from the standardization sample. Here, K-ABC scores for 585 school-age children referred for psychological evaluation were factor analyzed. Results of the analysis of K-ABC MP tests were quite consistent with those of previous analyses and with the structure of the test itself. The factor structure of the MP and Achievement tests together was also consistent with previous analyses and, like those analyses, was somewhat less consistent with the theoretical structure of the K-ABC; the factors found could be interpreted from several perspectives. As in analyses of the standardization data, the Achievement tests appear to be better measures of general intelligence for referred children than do the MP scales. Thus, while it appears that the K-ABC factor structure is quite consistent for both normal and exceptional children, the meaning and names of factors found are open to interpretation. 相似文献

The Kaufman-Assessment Battery for Children (K-ABC), a measure of cognitive functioning, was administered to 26 male and 24 female hearing-impaired elementary school students to determine its appropriateness for hearing-impaired children. The Wechsler Intelligence Scale for Children-Revised (WISC-R) also was administered. Scores for the present hearing-impaired sample on the K-ABC were compared with the normative group and were correlated with the WISC-R and standard achievement test scores. Results showed that both the Simultaneous Processing Scale and the Nonverbal Scale seemed appropriate for hearing-impaired children, whose scores were similar to those of the test's normative sample. Scores on the K-ABC also correlated highly with scores from the WISC-R. The Sequential Processing Scale was more problematic and not as useful. The K-ABC was significantly related to school achievement. Difficulties in the administration of the instrument with hearing-impaired children also are discussed. 相似文献

The purpose of the study was to investigate the use of the Kaufman Assessment Battery for Children (K-ABC)–Nonverbal Scale with severely hearing impaired children. The K-ABC was administered to 49 children enrolled at a public residential school for the deaf. Test instructions were given to one group employing American sign language (ASL), plus pantomime and gestures, while the other group received pantomime and gesture (PG) instructions only. No significant difference was found between the two group mean nonverbal K-ABC scores. Also, neither group scored significantly different from the K-ABC norms. Both groups scored significantly lower than K-ABC norms on the Spatial Memory subtest. Significant correlations were found between the K-ABC and Wechsler Intelligence Scale for Children-Revised (WISC-R). A significant correlation also was found between K-ABC scores and Reading Comprehension. A post hoc analysis of data found that, regardless of the instructional set, the children scored significantly lower on the Nonverbal K-ABC than they did on the WISC-R Performance Scale. The study provides support for the appropriateness of the K-ABC for use with deaf children. 相似文献

The validity of the Kaufman Assessment Battery for Children (K-ABC) was investigated with a sample of Black low SES preschool children. The sample consisted of 38 Black children who were enrolled in a Head Start program. The Stanford-Binet Intelligence Scale (SB-LM) was used as a criterion against which to compare K-ABC scores. While some support was obtained for the convergent and construct validity of the K-ABC, the results of this study suggest it may be no more culture fair for Black preschool children than is the SB-LM. 相似文献

The purpose of this study was to examine the relationship of the Kaufman Assessment Battery for Children (K-ABC), the WISC-R, and the Woodcock-Johnson Psychoeducational Battery (W-JPB), Part Two, with children who experience learning disabilities. Correlational analyses were used to examine relationships among the WISC-R, K-ABC Mental Processing and Achievement scales, and the W-JPB Achievement scales. Thirty-four children with learning disabilities (mean age 8–11 years) received all three measures. Correlation coefficients indicated stronger and more consistent relationships between the WISC-R and W-JPB Achievement tests than between the K-ABC and W-JPB Achievement tests. Significant relationships between the WISC-R Full Scale IQ and the K-ABC Mental Processing Composite (MPC) revealed evidence of validity for this learning disabled sample. However, correlation coefficients among the K-ABC Achievement subtests and the W-JPB Achievement clusters indicated both convergent and discriminant validity. Thus, it is suggested that both the K-ABC MPC, for assessment of cognitive abilities, and the W-JPB Achievement clusters could be employed in discrepancy formulas for special education placement of children with learning disabilities. 相似文献

The K-ABC and the Stanford-Binet IV (abbreviated test battery) were administered in a counterbalanced order to 32 gifted third- and fourth-grade students. It was found that the Stanford-Binet IV produced scores that were an average of eight points higher than those on the K-ABC. The concurrent validity coefficient of .70 indicated a high degree of association between test performance on these two tests. When the diagnostic heuristic of +2 SDs is used to identify gifted children, 68.6% concordance was found between these tests. Eighty percent of the discordance involved cases in which the Binet IQ was above +2 SDs and the K-ABC was below +2 SDs. Implication for the assessment of gifted children is discussed. 相似文献

The relationship between the new Kaufman Assessment Battery for Children (K-ABC) and the Revised Peabody Picture Vocabulary Test (PPVT-R) Forms L and M was explored for a sample of 30 predominantly black Head Start children. The highest correlations occurred between the K-ABC Achievement Scale and the PPVT-R. The K-ABC Expressive Vocabulary subtest correlated moderately highly with PPVT-R Form L, while the K-ABC Riddles subtest correlated moderately highly with PPVT-R Form M. Mean standard scores for the K-ABC Scales and subtests ranged from 11 to 20 points higher than those obtained on the PPVT-R. It would not appear redundant to administer the PPVT-R in addition to the K-ABC when one needs a receptive vocabulary measure. 相似文献

The validity of the Kaufman Assessment Battery for Children (K-ABC) (Kaufman & Kaufman, 1983) was investigated with a sample of preschool-age children. The sample consisted of 50 subjects aged 21/2 through 4 who were distributed roughly equally by age, sex, and race according to the 1980 census. The validity of the K-ABC was examined using the Slosson Intelligence Test (SIT) (Slosson, 1982) and the Classroom Behavior Inventory-Preschool Form (CBI) (Schaefer & Edgerton, 1978) as criterion measures. The SIT and CBI-Preschool Form Verbal Intelligence Scale were found to correlate significantly (p<.01) with the global scales of the K-ABC. The K-ABC did not differentiate between age or sex groups, but blacks scored lower than whites. The findings are supportive of previous validity studies (Kaufman & Kaufman, 1983) and two-factor theories of intelligence (e.g., Das, Kirby, & Jarman, 1975). 相似文献

The authors of the Kaufman Assessment Battery for Children (K-ABC) assert that, in addition to a discrepancy between learning potential and academic achievement, learning disability is characterized by poor sequential relative to simultaneous processing skills. The present study was designed to determine whether the K-ABC could discriminate between learning disabled and normal children on the basis of these characteristics. Forty-three LD pupils from 7 to 12 years of age and 20 normally achieving children of similar age were administered the K-ABC. Results indicated that, for both the LD and the normal children, scores on the Sequential Processing Scale were significantly lower than on the Simultaneous Processing Scale. In addition, the aiscrepancy between Simultaneous and Sequential scale scores was similarly distributed in both groups. The LD group scored lower and the normal group higher on the Achievement Scale than on the Mental Processing Composite. The results, therefore, indicated that the K-ABC differentiated LD from normal children in terms of Achievement relative to M.P.C. scores; however, it failed to reveal a unique profile pattern related to simultaneous vs. sequential processing skills for the LD group. Further analyses of the relationship between K-ABC processing scale scores and WISC-R scores, as recategorized by Bannatyne, revealed significant correlations between measures, indicating similar underlying theoretical constructs. 相似文献

Results of the K-ABC and Bender-Gestait Test were compared for a sample of LD children that included 24 blacks and 24 whites: mean age 9 years, SD = 1–2. A nonsignificant difference was found between the mean scores of the K-ABC Sequential and Simultaneous Scales. A significant (p<.01) correlation coefficient was found between the K-ABC Simultaneous Scale and the Bender-Gestalt Test error score (r = −.57). A nonsignificant correlation coefficient was found between the K-ABC Sequential Scale and the Bender-Gestalt Test error score (r = −.20). Implications of these findings are discussed. 相似文献

Convergent and discriminant validity of the Mental Processing Scales of the Kaufman Assessment Battery for Children (K-ABC) were examined using 51 first-grade children. Convergent validity was assessed using the Reading Recognition and Comprehension subtests of the Peabody Individual Achievement Test. Discriminant validity was assessed using a measure of anxiety/self-esteem, the Child Anxiety Scale, and a measure of hyperactive behavior, the Hyperactivity scale of the Achenbach Child Behavior Checklist. Results supported the convergent validity of the K-ABC; correlations with reading achievement were fairly large. The discriminant validity received only partial support. The K-ABC did not correlate with the Child Anxiety Scale, but did show rather large correlations with the measure of hyperactive behavior. Implications for understanding what the K-ABC Mental Processing Scales are measuring are discussed. 相似文献

Given the psychometric limitations of existing measures of Kolb's experiential learning model (ELM), two new scales of learning styles have been developed. The validity of these scales has been supported in samples of undergraduate and MBA students in the USA. This paper provides evidence of some psychometric properties of scores yielded by these scales using samples of undergraduate students in the UK. Only limited support is found for the internal consistency reliability and construct validity of scores produced by the scales. However, an item attrition exercise identifies a two‐factor solution providing an acceptable fit to the data. The scales are reported as being positively correlated with academic performance and prior academic achievement. Despite the mixed evidence, we suggest further development of the scales is warranted to create a psychometrically sound measure of the ELM. 相似文献

Eighty practitioners with varying levels of experience in the administration of the Kaufman Assessment Battery for Children (K-ABC) were asked to complete a K-ABC Abilities Matrix to indicate their perceptions of the specific abilities assessed by each of the ten K-ABC Mental Processing subtests. The practitioners' responses were compared to the perceptions of the K-ABC authors, and, in roughly half of the judgements, a majority of the practitioners agreed with the test authors, while the remaining judgements constituted majority disagreements. The practitioners associated additional psychoeducational abilities or skills, that had not been identified previously by the K-ABC authors, with several of the K-ABC subtests. 相似文献

The purpose of the present 2-experiment study was to determine whether a recently developed mnemonic numeric strategy could be used more independently by middle school students. In the context of associating various 18th-, 19th-, and 20th-century inventions with their dates, the authors found that students could successfully implement the strategy in a group-instructional context (as opposed to the one-on-one individual administrations of earlier investigations). The students were not, however, able to take the basic components of the strategy and effectively apply them without complete mnemonic pictorial support. That is, students did not create their own memory-enhancing visual images in the absence of instructor-provided interactive line drawings. The results are consistent with those of previous research documenting that less sophisticated learners (including middle school students) are unable to apply complex mnemonic strategies independently unless they are provided with sufficient auxiliary support to reduce information-processing demands. 相似文献
