An analysis of verbal-performance intelligence quotient discrepancies in the Wechsler Adult Intelligence Scale results of mentally subnormal hospital patients.

Verbal-Performance IQ discrepancies on the WAIS have been of much interest to clinical psychologists. They have been related, amongst other things, to different types of brain damage and in studies of the mentally subnormal, to successful adjustment to the outside world. This paper looks more closely at such discrepancies obtained by patients in a hospital for the mentally subnormal. These discrepancies are found to be both frequent related to Full Scale IQ. The pattern that emerges remains constant if scaled scores are considered or if the subtests are re-arranged according to Cohen's A and B factors. It is argued that these findings imply caution in the use of the discrepancy measure as a diagnostic or predictive indicator in this population.

Predictors of intelligence quotient and intelligence quotient change in persons treated for phenylketonuria early in life.

Ninety-one individuals with phenylketonuria who were treated early in life were followed for as many as 22 years. Regression analyses were used to determine the best predictors of IQ and IQ change. Among treatment-related variables, good dietary control of the blood phenylalanine level stood out as the best predictor of IQ. Diet discontinuation and the natural (off diet) blood phenylalanine level best predicted IQ loss, suggesting that diet continuation may be important for children with natural blood phenylalanine levels greater than 18 mg/dL.

Wechsler Adult Intelligence Scale and Wechsler Adult Intelligence Scale-Revised in a neurologically impaired population.

Compared Verbal, Performance, and Full Scale IQ scores from two groups of neurologically impaired patients (N = 114) similar in age, years of education, occupation, race, sex, and etiology and location of cerebral dysfunction. One group had been given the WAIS and the other the WAIS-R. All three IQ scores were higher for the WAIS group, with Full Scale and Verbal scores significantly (p less than .05) higher. Changes in item content and standardization sample cohort effects are offered as partial possible explanation for the results. The IQ scores from the two tests cannot be considered as interchangeable for neurological patients.

Social/emotional intelligence and midlife resilience in schoolboys with low tested intelligence.

Seventy-three inner-city boys with a mean IQ of 80 were followed prospectively from age 14 until age 65. Their adult adjustment was compared to a socioeconomically matched sample of 38 boys with a mean IQ of 115. Although childhood social disadvantage did not distinguish the groups with low and high IQs, half of the low-IQ men enjoyed incomes as high and had children as well-educated as did the high IQ men. These resilient low-IQ men were more likely to be generative, to use mature defenses, and to enjoy warm object relations than the high IQ group as a whole.

Differential estimation of verbal intelligence and performance intelligence scores from combined performance and demographic variables: the OPIE-3 verbal and performance algorithms.

Data from the WAIS-III standardization sample (The Psychological Corporation, 1997) was used to generate VIQ and PIQ estimation formulae using demographic variables and current WAIS-III subtest performances. The sample (n = 2450) was randomly divided into two groups; the first was used to develop formulas and the second to validate the regression equations. Age, education, ethnicity, gender, region of the country as well as Vocabulary, Matrix Reasoning, and Picture Completion subtests raw scores were used as predictor variables. Prediction formulas were generated using a single verbal and two performance subtest algorithms. The VIQ OPIE-3 model combined Vocabulary raw scores with demographic variables. The PIQ estimation algorithm used Matrix Reasoning and Picture Completion raw scores with demographic variables. The formulas for estimating premorbid VIQ and PIQ were highly significant and accurate in estimation. Differences in estimated VIQ and PIQ scores were evaluated and the OPIE-3 algorithms were found to accurately predict VIQ and PIQ differences within the WAIS-III standardization sample.
