Various short forms of the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III; D. Wechsler, 1997) have been investigated, but limited information is available regarding the usefulness of any WAIS-III abbreviation with intellectually deficient individuals. Our study compared the validities of two WAIS-III selected-item short forms in a sample of 59 individuals with full scale IQs (FSIQs) of 79 or lower. The performance of both short forms was adequate, but the results gave a consistent edge to an adapted version of the Satz-Mogel (1962) short form in comparison to the abbreviated form by J. H. Wymer, K. Rayls, and M. T. Wagner (2003). The correlation (r = .98) of Satz-Mogel estimates with WAIS-III FSIQ scores was slightly higher than the correlation (r = .97) for estimates from Wymer et al.'s abbreviated form, and Satz-Mogel estimates did not differ significantly from actual FSIQs. In comparison to individual classification (FSIQ > 70 versus FSIQ < or = 70) obtained with the full WAIS-III, the misclassification rate was somewhat lower for the Satz-Mogel short form. Although both short forms performed reasonably well, practitioners should be cautious when utilizing any short form to make decisions about individuals. 相似文献

Although the Wechsler Full Scale IQ (FSIQ) is a common component of most neuropsychological evaluations, there are many clinical situations where the complete administration of this battery is precluded by various constraints, including limitations of time and patient compliance. These constraints are particularly true for dementia evaluations involving elderly patients. The present study reports data on two short forms particularly suited to dementia evaluations, each requiring less than 20min of administration time. One of the short forms was previously validated in dementia for the WAIS-R [Randolph, C., Mohr, E., & Chase, T. N. (1993). Assessment of intellectual function in dementing disorders: Validity of WAIS-R short forms for patients with Alzheimer's, Huntington's, and Parkinson's disease. Journal of Clinical and Experimental Neuropsychology, 15, 743-753]; the second was developed specifically for patients with motor disabilities. These short forms were validated using the WAIS-III normative standardization sample (N=2450), neurologic sample (N=63), and matched controls (N=49), and a separate mixed clinical sample (N=70). The results suggest that each short form provides an accurate and reliable estimate of WAIS-III FSIQ, validating their use in appropriate clinical contexts. The present data support the use of these short forms for dementia evaluations, and suggests that they may be applicable for the evaluation of other neurological and neuropsychiatric disorders that involve acquired neurocognitive impairment. 相似文献

The validities of Kaufman's (1976) four-subtest short form and Kennedy and Elder's (1982) five-subtest short form for the WISC-R were evaluated in 98 children with traumatic brain injury. Both forms correlated highly with actual WISC-R FSIQ, and both forms had acceptable relationships to measures of injury severity. However, the Kaufman method had a larger standard error of measurement than did the Kennedy and Elder method, and the Kaufman method tended to overestimate actual FSIQ. It was concluded that the Kennedy and Elder short form for the WISC-R may be a relatively more accurate predictor of actual FSIQ in children with traumatic brain injury. 相似文献

Evaluation of intellectual abilities using the WAIS-III is a common component of neuropsychological assessments. However, clinicians might be interested in administering reliable and valid short forms due to practical and clinical reasons. The present study examined the concurrent validity of eight short forms of the WAIS-III with full form IQ scores in a sample (n=43) of geriatric outpatients referred for assessment of suspected dementia. There were no significant differences between the short and full form VIQ scores at P<.01, while half of the short form PIQ and FSIQ scores were significantly different from their respective full form scores at P<.01. Correlations between short and full form IQ scores ranged from .89 to .99. Seven-subtest short forms were able to accurately estimate over 80% of scores within +/-2 S.E.M.s. This study supports limited use of WAIS-III short forms when conducting evaluations of older adults with suspected dementia. 相似文献

The application of seven-subtest short forms of the Wechsler Adult Intelligence Scale-III (WAIS-3) was evaluated in a sample of 281 mixed clinical patients from three Veterans Affairs Medical Centers. Short-form summary scores were derived from deviation quotient tables and from prorating. They included either Block Design or Matrix Reasoning. Short-form summary scores for Full-Scale IQ (FSIQ) and Verbal IQ (VIQ) demonstrated good alternate-forms reliability with the full WAIS-3 scores, whereas Performance IQ (PIQ) summary scores were less accurate. Short forms derived from deviation quotients and prorating did not differ from each other. However, the inclusion of Matrix Reasoning resulted in somewhat better accuracy with WAIS-3 PIQ than did Block Design. The results of this study support the use of the seven-subtest short form of the WAIS-3 in estimating full WAIS-3 summary scores, especially for FSIQ and VIQ. 相似文献

A short form of the WPPSI, which consisted of the Block Design, Vocabulary, Arithmetic, and Comprehension subtests, was administered to 426 applicants to kindergarten at a private school. The following year a short form WPPSI-R, which consisted of the same subtests, was administered to 372 applicants to kindergarten at the same school. The FSIQs and subtest scores of the two short forms were nearly identical. The findings varied from the results of previous studies that found the complete WPPSI FSIQ to be 6 to 8 points higher than the WPPSI-R FSIQ. Limitations of the present study and of short form Wechsler IQs are discussed. 相似文献

This study investigated the comparability between three “amazingly” short forms of the WAIS-R (a dyad, triad, and tetrad) suggested by Kaufman, Ishikuma, and Kaufman-Packer (1991) and the complete battery among a sample of 114 educable mentally handicapped adolescents. Results indicate that the short forms are highly correlated with the complete battery Full Scale IQs, and all three short forms yielded scores, on average, within 2 points of the complete battery. Analyses at an individual level revealed that more than 90% of the sample fell within 3 SEM (9 points) of the FSIQ for all three short forms. Overall results are consistent with previous studies and support the use of these “amazingly” short forms. 相似文献

The Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) often poses problems for many populations due to the length of administration. Twenty geriatric subjects were administered the full WAIS-III. Three abbreviated forms of the WAIS-III (Satz-Mogel abbreviation; seven-subtest short form; and a clinically derived abbreviation) were evaluated by rescoring original full WAIS-III protocols. Results showed that the abbreviated WAIS-III protocols were highly correlated with complete protocols, and classification rules were the highest for the clinically derived abbreviation. The clinically derived abbreviation was reevaluated in a college LD/ADHD population yielding similarly high correlations. Results support the use of abbreviated forms of the WAIS-III in the evaluation of elderly patients and young adults, and point to the clinically derived abbreviation as providing the smallest discrepancies from FSIQ. 相似文献

BackgroundSchool-aged children born very preterm have been suggested to have worse cognitive and behavioral outcomes than children born full-term. Executive function (EF) is a higher level of cognitive function related to academic achievement. The present study aimed to evaluate the cognitive (including EF) and behavioral outcomes of Korean children born extremely preterm (EP) and to analyze any biological or socioeconomic risk factors for poor cognitive outcomes in this population.MethodsA total of 71 infants weighing < 1,000 g at birth or born before 30 weeks of gestation (EP group) who were admitted to the neonatal intensive care unit from 2008 to 2009 were included in this study and compared with 40 term-birth controls. The Korean Wechsler Intelligence Scale for Children-Fourth Edition, Advanced Test of Attention (ATA), Stroop test, Children''s Color Trails Test (CCTT), and Wisconsin Card Sorting Test (WCST) were used. Additionally, the Korean Child Behavior Checklist (K-CBCL) and Korean ADHD Rating Scale (K-ARS) were completed. Perinatal and demographic data were collected and analyzed.ResultsThe mean full-scale intelligence quotient (FSIQ) score in the EP group was significantly lower than that of the term control group (89.1 ± 18.3 vs. 107.1 ± 12.7; P < 0.001). In the EP group, 26 (37%) children had an FSIQ score below 85, compared to only one child (3%) in the control group. Furthermore, the EP group showed significantly worse EF test results (ATA, Stroop test, CCTT, WCST). Except for the higher social immaturity subscore in the EP group, the K-CBCL and K-ARS scores were not different between the two groups. EP children who received laser treatment for retinopathy of prematurity (ROP) had an 8.8-fold increased risk of a low FSIQ score, and a 1-point increase in the discharge weight Z-score decreased the risk of a low FSIQ score by approximately half in this EP cohort.ConclusionThis is the first Korean study to investigate the cognitive and behavioral outcomes of school-aged children born EP. In the study cohort, EP children exhibited significantly lower FSIQ scores and EF than their full-term peers, and 37% of them had cognitive problems. Nonetheless, except for social immaturity, the behavioral problems were not different in EP children. Severe ROP and low discharge weight Z-score were identified as independent risk factors for low FSIQ score after adjusting for birth weight. 相似文献

Variability of metabolic control in phenylketonuria (PKU) potentially affects cognitive outcome in early and continuously treated children with this condition. The possibility that homeostasis is more important than the absolute level of exposure to phenylalanine (phe) has not previously been examined. A meta-analysis of 40 studies showed that in children with phenylketonuria (PKU), mean lifetime blood phe levels were significantly correlated with Full Scale IQ (FSIQ) (r=-0.34). A similar correlation (r=-0.35) was found between FSIQ and mean exposure during 0-12 years of age. Most of the studies in the meta-analysis, however, included children who had discontinued the phe restricted diet. None examined the impact of fluctuations in metabolic control in continuously treated children. This is important because new therapies may increase stability in blood phe levels. The question has arisen whether these therapies are beneficial in children whose blood phe levels are generally within the recommended range of 120-360 micromol/L. In this study, we describe the relationship between FSIQ and two parameters of metabolic control: (1) mean blood phe level of all reported specimens for each subject, and (2) variability of the blood phe level as indicated by the standard deviation of blood phe levels for each subject. Analyses were performed using lifetime phe levels and levels during three periods (0-6 years, 0-10 years, and >10 years of age). The most recent FSIQ for each child was used in the correlation analyses. Data were collected from medical records on all 46 children born between 1999 and 2006 with early and continuously treated PKU followed at the Metabolism Program at Children's Hospital Boston. The mean age of the children at the time of their most recent FSIQ test was 7.5+3.3 (2.9-15.5) and their mean FSIQ was 104+15 (68-143). The mean lifetime blood phe level in these children was 312+132 micromol/L (125-852). The standard deviation of blood phe levels was 182+72 micromol/L (96-336). The correlation between lifetime blood phe levels and most recent FSIQ was -.17 (p=0.38) and the correlation between standard deviation of blood phe levels and most recent FSIQ was -.36 (p=.058), not reaching significance, but indicating a trend. These results indicate that stability of blood phe levels may be more important to cognitive functioning than overall exposure to phe in early and continuously treated PKU. In treating PKU, attention should be given to variability in blood phe levels as well as maintenance of phe levels within the recommended range. 相似文献

The Oklahoma Premorbid Intelligence Estimate-3 (OPIE-3) combines Wechsler Adult Intelligence Scale-3rd edition (WAIS-III) subtest raw scores (vocabulary, information, matrix reasoning, and picture completion) and demographic data (i.e., age, education, gender, ethnicity, and region) to predict FSIQ scores. Differences between OPIE-3 estimated FSIQ scores and actual FSIQ scores were compared across 13 age groups in a random sample (N=1201) of the WAIS-III standardization sample. There were mean differences in estimated FSIQ between age groups (P<.01). There was a trend that the OPIE-3 algorithms underestimated FSIQ for individuals 16-17 (2.7 points) and 80-89 years old (3.5 points). However, the differences in estimation errors were small and the percentage of individuals misclassified by more than 10 FSIQ points by age group was similar across groups. The OPIE-3(2ST), OPIE-3MR, and OPIE-3VOC yielded robust estimates of FSIQ across age groups in a neurologically intact sample. Limitations, particularly with individuals aged 16-17 and 85-89 years, are discussed. 相似文献

Measures of intelligence were collected in 209 twin pairs at 5, 7, 10, and 12 years of age, as part of a longitudinal project on intelligence, brain function, and behavioral problems. Intelligence was measured at 5, 7, and 10 years of age with the RAKIT, a well-known Dutch intelligence test, consisting of 6 subscales. At 12 years of age, the complete WISC-R was administered (12 subscales). Both intelligence tests resulted in a measure of full-scale IQ (FSIQ). Participation rate is around 93% at age 12. Correlation coefficients over time are high: (r(5–7) = .65; r(5–10) = .65; r(5–12) = .64; r(7–10) = .72; r(7–12) = .69 and r(10–12) = .78). Genetic analyses show significant heritabilities at all ages, with the expected increase of genetic influences and decrease of shared environmental influences over the years. Genetic influences seem to be the main driving force behind continuity in general cognitive ability, represented by a common factor influencing FSIQ at all ages. Shared environmental influences are responsible for stability as well as change in the development of cognitive abilities, represented by a common factor influencing FSIQ at all ages and age-specific influences, respectively. 相似文献

This study developed regression algorithms for estimating IQ scores using the Canadian WAIS-III norms. Participants were the Canadian WAIS-III standardization sample (n = 1,105). The sample was randomly divided into two groups (Development and Validation groups). The Development group was used to generate 12 regression algorithms for FSIQ and three algorithms each for VIQ and PIQ. Algorithms combined demographic variables with WAIS-III subtest raw scores. The algorithms accounted for 48-78% of the variance in FSIQ, 70-71% in VIQ, and 45-55% in PIQ. In the Validation group, the majority of the sample had predicted IQs that fell within a 95% CI band (FSIQ=92-94%; VIQ=93-95%; PIQ=94-94%). These algorithms yielded reasonably accurate estimates of FSIQ, VIQ, and PIQ in this healthy adult population. It is anticipated that these algorithms will be useful as a means for estimating premorbid IQ scores in a clinical population. However, prior to clinical use, these algorithms must be validated for this purpose. 相似文献

The relative performance of six Wechsler Adult Intelligence Scale-Revised short forms (Brooker & Cyr, 1986; Reynolds, Wilson, & Clark, 1983; Silverstein, 1982) was examined for a group of psychiatric inpatients (N = 50). Short forms were evaluated according to their ability to predict the Full Scale IQ using regression analysis. The standard error of estimate was significantly smaller for Silverstein's (1982) four-subtest short form, which consists of Vocabulary, Arithmetic, Picture Arrangement, and Block Design. Using the Silverstein (1982) tables, 90% of the short form IQs fell within +/- 6 points of the actual Full Scale IQ. 相似文献

This study was conducted to investigate long-term neurocognitive outcomes and to determine associated risk factors in a cohort of Korean survivors of childhood acute lymphoblastic leukemia (ALL). Forty-two survivors of ALL were compared with 42 healthy controls on measures of a neurocognitive test battery. We analysed potential risk factors (cranial irradiation, sex, age at diagnosis, elapsed time from diagnosis, and ALL risk group) on neurocognitive outcomes. ALL patients had lower, but non-significant full-scale intelligence quotient (FSIQ, 107.2±12.2 vs. 111.7±10.2), verbal intelligence quotient (VIQ, 107.7±13.6 vs. 112.2±11.4), and performance intelligence quotient (PIQ, 106.3±14.2 vs. 110.1±10.7) scores than healthy controls. However, patients treated with cranial irradiation performed significantly lower on FSIQ (102.2±8.1), VIQ (103.3±11.7), and PIQ (101.4±13.2) compared to non-irradiated patients and healthy controls. ALL patients also had poor attention, concentration, and executive functions. Among ALL survivors, cranial irradiation was a risk factor for poor FSIQ, being male was a risk factor for poor PIQ, and younger age was a risk factor for poor attention. Therefore, the delayed cognitive effects of ALL treatment and its impact on quality of life require continuing monitoring and management.

Total scores of the Raven's Standard Progressive Matrices (SPM) were correlated with Wechsler Adult Intelligence Scale-Revised Full Scale IQs (WAIS-R FSIQ) in order to obtain age-stratified estimates of WAIS-R FSIQ (N = 308). Results show a significant positive correlation between age-stratified WAIS-R FSIQ and SPM in all age groups except those 65 and older and between educational level and SPM for all age groups except the very young (16 to 24 years), the 55- to 64-year-olds, and the elderly (65 and older). A multiple regression and cross-validation revealed that race and age also must be used as moderator variables when one is predicting FSIQ in this population. It is concluded that the SPM can be used as an estimate of WAIS-R FSIQ. 相似文献

This study investigated the relationships among the Peabody Picture Vocabulary Test-Revised (PPVT-R) alternate forms and, also, the relationship of each PPVT-R form with the Wechsler Adult Intelligence Scale-Revised (WAIS-R) for a referred sample of 60 adult clients of the California State Department of Rehabilitation. Clients ranged in age from 18-3 to 37-7 (M = 25-7, SD = 5-9). PPVT-R alternate forms r = .88 was significant at p less than .001. Correlations with the WAIS-R VIQ were .82 for L, .78 for M; with PIQ, .46 for L, .38 for M; with FSIQ, .77 for L, .67 for M. All correlations with both forms of the PPVT-R were significant. PPVT-R mean scores did underestimate significantly all WAIS-R mean scores. Implications are discussed. 相似文献

This study examined the relationship between the Peabody Picture Vocabulary Test-Third Edition (PPVT-III) and Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) using 40 adults who ranged in age from 18 to 41 (mean age of 22 years). Participants were administered the PPVT-III and WAIS-III in counterbalanced fashion to control for order effects. Results revealed that the PPVT-III score was related to the WAIS-III Verbal IQ (VIQ) and Full Scale IQ (FSIQ) scores but unrelated to the Performance IQ (PIQ) score. In addition, analyses indicated that, while there were no significant differences between the PPVT-III score and WAIS-III mean FSIQ and PIQ scores, the PPVT-III mean score was significantly lower than the WAIS-III VIQ. Further analysis indicated that the PPVT-III adequately estimated WAIS-III FSIQ and VIQ scores for participants who were classified as Average or High Average on the WAIS-III. However, for participants in the Superior range, the PPVT-III tended to underestimate FSIQ and VIQ scores by approximately 10 points. 相似文献

The WISC-III and Kaufman Adolescent and Adult Intelligence Test (KAIT) were administered to 30 delinquents in a county youth center as part of their routine psychological assessment. The P > V discrepancy found in earlier studies of delinquent WISC-R IQs was not found with the WISC-III. However, the Fluid IQs on the Kaufmans' test averaged 11 IQ-points higher than the WISC-III IQs. There was a mean difference of 8.66 points between the KAIT Composite IQ and the WISC-III FSIQ, in favor of the former. These findings suggest KAIT IQs that are significantly higher than WISC-III scores (p < .001). The implications are discussed. © 1996 John Wiley & Sons, Inc. 相似文献
