The cross-cultural applications of the KAIT: case studies with three differentially acculturated women.

The Kaufman Adolescent and Adult Intelligence Test (KAIT), introduced in 1993, is a relatively new measure for the assessment of intelligence. Because of the test's theoretical foundation, standardization procedure, test items, and score interpretations, it is assumed to be a culturally sensitive measure. However, there is little supporting clinical or empirical evidence. The present case study examined cross-cultural applications of the KAIT using 3 volunteers from diverse cultural backgrounds with differential levels of American acculturation. In addition to test scores, the participants' impressions of the testing process were measured with the Subjective Units of Distress Scale. Preliminary evidence suggests that the KAIT, like its predecessor, the K-ABC, may be useful when working with culturally diverse people.

Structure of Witkin's Embedded Figures Test.

A number of reports have indicated that Witkin's Embedded Figures Test correlates with performance on standard intelligence tests. This finding was replicated in a recent factor analytic study when the test loaded substantially on a factor best representing the performance subtests of the Wechsler Adult Intelligence Scale (WAIS). However, the embedded figures also loaded on an uncorrelated factor, in addition to those normally associated with WAIS, which would relate well to Witkin's conception of psychological differentiation. These loadings on two uncorrelated factors suggested that the factorial structure of the Embedded Figures Test should be examined. An item analysis indicated a bi-factorial structure and, as presently constituted, the scale will provide misleading and ambiguous information.

Psychological test findings on pathological gamblers in treatment.

A sample of 23 veterans entering the Pathological Gambling Treatment Program at the Veterans Administration Medical Center in Miami, Florida, were administered a battery of tests including the following: Wechsler Adult Intelligence Scale (WAIS), Minnesota Multiphasic Personality Inventory (MMPI), Edwards Personal Preference Schedule (EPPS), and the Personal Orientation Inventory (POI). Findings on the intelligence testing indicated that on the average the pathological gamblers were of bright normal intelligence with a mean WAIS Full Scale IQ of 116.78, mean Verbal IQ of 119.30, and a mean Performance IQ of 111.30. Group profile results on the MMPI showed significant mean clinical scale elevations on two of the nine clinical scales: Scale 2, Depression; and Scale 4, Psychopathic Deviate. Group profile results on the EPPS indicated relatively high scores on the variables of achievement, exhibition, autonomy, dominance, and heterosexuality; and relatively low scores on the variables of deference, order, and endurance. Group profile results on the POI were essentially within normal limits with a tendency toward time incompetency noted, suggesting difficulty living fully in the present here and now.

[Vocabulary of young children with sensorineural deafness].

UNLABELLED: The primary aim of the study was to measure the receptive and expressive vocabulary with respect to clinical parameters and selected socio-demographic variables and to assess whether the size of vocabulary could be predicted by certain variables in a consecutive series of children identified as having bilateral sensorineural hearing loss ("Göttinger Hör-Sprachregister"). METHOD: All children aged between 2;6 to 6;3 years diagnosed in the Department of Phoniatrics/Pedaudiology of the University Göttingen as having a permanent bilateral sensorineural hearing impairment ("Göttinger Hör-Sprachregister") in a defined period (july 1995-september 2000) were examined with standardized receptive and expressive vocabulary tests as well as a nonverbal intelligence test (on average 5.5 months after diagnosis and 2.9 months after fitting with hearing aids). SAMPLE: 37 children (20 boys, 17 girls). Mean age at diagnosis: 48.5 (SD 15.9; min. 18, max. 75) months, mean age at hearing aid fitting: 51 months (SD 15.2). Multiple handicapped children, children with additional conductive hearing impairment and those with postnatal losses were excluded. The sample as a whole demonstrated lexical deficits of varying severity that were greater in the expressive than in the receptive vocabulary, depending on the clinical parameter. Children with congenital hearing impairment, with severe-to-profound hearing impairment (> 70 dB) and bilingual children demonstrated on average the smallest receptive and expressive vocabulary. An early fitting with hearing aids did not correspond with a better lexical development when a severe-to-profound hearing impairment existed. Severity of a hearing impairment and nonverbal intelligence significantly predicted the average size of the receptive vocabulary. A moderate hearing impairment, high non-verbal intelligence, and gender (female) emerged as the strongest significant predictors of the expressive vocabulary. The vocabulary test result of a bilateral sensorineurally hearing-impaired child may be an indicator for early cognitive training.

HIV-related ocular microangiopathic syndrome and cognitive functioning.

Ocular microangiopathic syndrome is found frequently in patients with AIDS or severe HIV infection. Symptoms of this microvascular syndrome can include cotton-wool spots, hemorrhages, and Roth's spots. The clinical and functional significance of HIV-related ocular microangiopathic syndrome has not been clarified as yet. The objective of this study was to evaluate a possible association between HIV-related ocular microangiopathic syndrome and cognitive functioning. Thirty-seven patients infected with HIV (24 with AIDS) underwent ophthalmological and neuropsychological examination. HIV-related ocular microangiopathic syndrome was measured by counting the number of cotton-wool spots in both eyes. Neuropsychological examination included five standardized tests, with the first three primarily measuring function of short-term memory; these tests were as follows: the Auditory-Verbal Learning Test, the Benton Test, the Stroop Colour Word Test, the Trail-Making Part B test, and the Vocabulary for Measuring Premorbid Intelligence test. HIV-related ocular microangiopathic syndrome was found in 15 patients with AIDS (62.5%), and in one patient, staged Walter Reed 5. In 10 patients, one eye was affected (mean count of cotton-wool spots 1.5). In six patients, both eyes were affected (mean count of cotton-wool spots 7.0). Univariate correlations between the number of cotton-wool spots in both eyes and test scores were as follows: Auditory-Verbal Learning Test: 0.56 (p < 0.001); Benton Test: 0.51 (p < 0.001); Stroop Colour and Word: 0.50 (p < 0.001); Trail-Making Part B: 0.15 (not significant); Vocabulary for Measuring Premorbid Intelligence: -0.05 (not significant). Multiple correlation between the test scores and the number of cotton-wool spots was 0.70 (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Elementary school performance of children with congenital hypothyroidism. New England Congenital Hypothyroidism Collaborative.

The aim of this study was to determine whether hypothyroid children treated early as a result of diagnosis after neonatal screening progressed normally in school. The New England Congenital Hypothyroidism Collaborative studied 72 of its patients at the ages of 9 or 10 years after they had completed 3 years of schooling beyond kindergarten. Control subjects were 96 classmates of the same sex and age as the patients and 32 siblings of appropriate age for the testing. Intelligence quotients (IQs) were measured by the Wechsler Intelligence Scale for Children-Revised abbreviated to five items, and school achievement by the Peabody Individual Achievement Test. In addition, a series of neuropsychologic tests was administered to both patients and control subjects. Educational histories were obtained from the parents for 74 patients, 87 of their siblings, 96 classmates, and 96 siblings of the classmates. The IQ of the control subjects (mean +/- SEM) was 109 +/- 1.2 versus 106 +/- 1.4 for the patients. The mean overall achievement score was 109 +/- 0.93 for the control subjects and 108 +/- 1.3 for the patients. These differences are not statistically significant. The regression lines relating overall Peabody Individual Achievement Test scores or subtests thereof to IQ did not differ among the patients and the control groups. Within the groups the regression lines for IQ and the different subtests of school achievement were also identical. The percentages of children repeating a grade, needing extra tutoring, or in special classes were the same for patients and control groups. We conclude that children with hypothyroidism have no apparent specific impediments to learning unrelated to intelligence.

Rising verbal intelligence scores: implications for research and clinical practice.

Evidence suggests that scores on various intelligence tests have been rising at a fast rate. To find out whether performance on the Wechsler Adult Intelligence Scale (WAIS) Vocabulary subtest has also been rising, the authors searched major psychology journals for investigations involving healthy younger and older adult participants and collected the reported WAIS Vocabulary scores. The meta-analysis shows that WAIS Vocabulary scores have been rising at the rate of 0.117/year (corresponding to 1.52 IQ points/decade) for younger adults and 0.367/year (corresponding to 4.79 IQ points/decade) for older adults.

Intellectual performance of children with maple syrup urine disease.

The intellectual performance of 22 children aged 3-16 years with maple syrup urine disease (MSUD) was assessed and compared to a group of early treated phenylketonuria (PKU) children and normal subjects matched by age, sex, nationality, and socio-economic status. All subjects were tested by one examiner only using the age related versions of the non-verbal Snijders-Oomen intelligence test. The mean IQ (+/- SD) score was 74 +/- 14 (range 50-103) in patients with MSUD, 101 +/- 12 (range 87-125) in early treated PKU patients, and 107 +/- 9 (range 90-122) in normal subjects. Intercorrelations indicated that length of time after birth that plasma leucine concentration remained > 1 mmol/l and quality of long-term metabolic control have important influences on IQ.

[Neuropsychological sequelae in children with AML treated with or without prophylactic CNS-irradiation].

BACKGROUND: In study AML-BFM 87 the relapse rate was lower in patients receiving cranial irradiation (CRT). However, CRT has always been associated with adverse cognitive side effects. Therefore, the impact of CRT on neuropsychological function in children with AML was retrospectively evaluated. PATIENTS: We tested 53 children (30 boys, 23 girls) treated according to the AML-BFM-87 protocol (median age at diagnosis: 8.5 years, range 0.3 - 17.5; median time since diagnosis: 5.7 yrs, 3.8 - 10.7 yrs). To avoid any bias from additional therapy elements, patients with relapse or initial CNS involvement and transplanted patients were excluded (n=32). Our cohort was representative of the total group of 104 long term survivors of study AML-BFM 87. CNS prophylaxis consisted of ARA-C i.th., high dose ARA-C i. v. and either no CRT (n=15) or CRT (n=38) at a dose of 12 - 18 Gy depending on age. METHODS: Neuropsychological function was evaluated by psychological tests of attention and concentration (test d2 by Brickenkamp) and an intelligence test (Progressive Matrices by Raven). In addition, patients and their parents were interviewed about the occurrence of learning problems, subjective deficits in concentration and physical impairment. RESULTS: In the total group, no significant differences were seen between irradiated and non-irradiated patients regarding the psychological tests. However, the irradiated patients scored below the non-irradiated control group in test "d2" (concentration: 41st vs. 59th percentile). In the interview, irradiated patients tended to report more learning problems (lp) (10/36 vs. 1/14; p=0.15) and subjective deficits in concentration (con). In irradiated girls (con: 6/15 vs. 0/8; p=0.06; lp: 5/15 vs. 0/8; p=0.12) and younger patients (0 - 5 years at diagnosis; con: 7/12 vs. 2/9; p=0.18; lp 3/10 vs. 1/9; p=0.18) this trend was even more pronounced. CONCLUSION: Children with AML and CRT had no significant intellectual impairment in standardized tests when compared to non-irradiated patients. However, more irradiated patients reported learning problems and subjective concentration deficits.

Cortical volume and speed-of-processing are complementary in prediction of performance intelligence.

The rationale for the present study was to investigate the relationship between cortical volume, the latency of the ERP component P3a (as a measure of speed-of-processing), and performance intelligence (not adjusted for age differences). Seventy-one participants aged 20-88 years underwent a visual 3-stimuli oddball ERP task, an MRI-scan, and intelligence testing. P3a latency and cortical volume shared 9% variance (p<.05) and both were significantly related to performance intelligence (R2=.26 and .40, respectively). The amount of explained variance increased significantly (to R2=.51) when both measures were used as simultaneous predictors. When a path diagram was constructed including age as an exogenous variable, P3a latency and cortical volume both significantly predicted performance intelligence, but were no longer related to one another. The main conclusion from the study is that speed and size are complementary in prediction of performance intelligence, and the theoretical implications are discussed.

Familial studies of intelligence: a review.

A summary of 111 studies identified in a survey of the world literature on familial resemblances in measured intelligence reveals a profile of average correlations consistent with a polygenic mode of inheritance. There is, however, a marked degree of heterogeneity of the correlations within familial groupings, which is not moderated by sex of familial pairing or by type of intelligence test used.

Diagnosing item score patterns on a test using item response theory-based person-fit statistics.

Person-fit statistics have been proposed to investigate the fit of an item score pattern to an item response theory (IRT) model. The author investigated how these statistics can be used to detect different types of misfit. Intelligence test data were analyzed using person-fit statistics in the context of the G. Rasch (1960) model and R. J. Mokken's (1971, 1997) IRT models. The effect of the choice of an IRT model to detect misfitting item score patterns and the usefulness of person-fit statisticsfor diagnosis of misfit are discussed. Results showed that different types of person-fit statistics can be used to detect different kinds of person misfit. Parametric person-fit statistics had more power than nonparametric person-fit statistics.

[Mental deterioration in childhood epilepsy. I. Neuropsychological and electroencephalographic studies].

To clarify the pathogenesis of mental deterioration in epilepsy, neuropsychological and electroencephalographic studies were performed. Thirty-seven children were classified into two groups: group I consisted of 24 children with mental deterioration during the clinical course of their epilepsy, and group II consisted of 13 children without mental deterioration. Mental deterioration was assessed on the basis of the intelligence test scores during follow-up studies. The mean intelligence quotient of 24 children in group I decreased from 91.8 +/- 11.5 to 64.3 +/- 15.4 during a mean period of 4.4 years. Significant differences were found between the two groups in the levels of both representation (association function) and automation (auditory closure, visual recognition and visual-motor function). There were also significant differences between the two groups in the continuation of epileptic discharges on EEG, in the persistence of epileptic attacks at the final visit, and in the numbers of antiepileptic drugs at the neuropsychological examination. The degree of mental deterioration was correlated with the defect in the association function and, eleven children in group I showed mental deterioration even after their attacks had been suppressed.

[Psychomotor development of children born operatively by Caesarian section, vacuum or forceps in the period between 3 and 7 years (author's transl)].

In the period between 1966 and 1977 9,591 children were born at the UFK, Mannheim, and of these 1.008 were operative deliveries (10.5%). Out of these children, 99 of those delivered by section, 39 by forceps, 140 by vacuum and 67 spontaneous births were examined in an alphabetically determined group (R) for mental and motor development. The means used for the follow-up investigation were the Kramer-Binet Intelligence Test, and careful questioning of the parents on their children's early development. No connection between the type of delivery and intelligence quotient could be determined. A mean IQ of 114.4 was found for those delivered by section, 116.6 for those by forceps, and 117.7 for thos delivered by vacuum. The spontaneously-born children had an IQ of 108.7. The IQ results determined were correlated with the following data: EPH-gestosis, alteration in the child's heart sounds, protracted birth and Apga. No significant differences in the intelligence or any delayed motor development could be found in relation to the comparative group.

The locus of so-called IQ test results in reading disabilities.

It would appear the question of relevance of IQ in the assessment and remediation of children with RD is not quite the relevant question to ask, if only traditional intelligence tests are the focus. From the psychoeducational point of view of refining diagnosis, and from the administrative perspective of accountability, it would be helpful to accept a threshold of something like an IQ of 85 as the lower bound in defining learning or reading disabilities. A discrepancy from this threshold as derived from regression analysis or other more refined analyses and taking into account varying reliabilities, intercorrelations, and standard errors of measurement of different measuring instruments may constitute a learning or reading disability. How discrepant the aptitude-achievement should be to constitute a "significant" difference is a function of, among other factors, the material and human resources available to any particular school system. Leong (1987) has made suggestions for essentially a two-stage assessment leading to more refined diagnosis with the use of well-standardized group tests and teachers' estimates for the first stage (assessment) and more refined individual tests to diagnose those showing discrepant aptitude-learning performance in the border-zone. The rationale is that all those children requiring special services are so served and those in the uncertainty region must be carefully diagnosed so as to minimize so-called "misfits" in accordance with signal detection principles. It should be noted that the diagnosis of learning or reading disabilities can never be exact, even with the use of reliable and valid test instruments, and the "fuzzy set" approach should apply to the process (Horvath, Kass, & Ferrell, 1980).(ABSTRACT TRUNCATED AT 250 WORDS)

A process for developing community consensus regarding the diagnosis and management of attention-deficit/hyperactivity disorder.

There remain large discrepancies between pediatricians' practice patterns and the American Academy of Pediatrics (AAP) guidelines for the assessment and treatment of children with attention-deficit/hyperactivity disorder (ADHD). Several studies raise additional concerns about access to ADHD treatment for girls, blacks, and poorer individuals. Barriers may occur at multiple levels, including identification and referral by school personnel, parents' help-seeking behavior, diagnosis by the medical provider, treatment decisions, and acceptance of treatment. Such findings confirm the importance of establishing appropriate mechanisms to ensure that children of both genders and all socioeconomic, racial, and ethnic groups receive appropriate assessment and treatment. Publication of the AAP ADHD toolkit provides resources to assist with implementing the ADHD guidelines in clinical practice. These resources address a number of the barriers to office implementation, including unfamiliarity with Diagnostic and Statistical Manual of Mental Disorders criteria, difficulty identifying comorbidities, and inadequate knowledge of effective coding practices. Also crucial to the success of improved processes within clinical practice is community collaboration in care, particularly collaboration with the educational system. Such collaboration addresses other barriers to good care, such as pressures from parents and schools to prescribe stimulants, cultural biases that may prevent schools from assessing children for ADHD or may prevent families from seeking health care, and inconsistencies in recognition and referral among schools in the same system. Collaboration may also create efficiencies in collection of data and school-physician communications, thereby decreasing physicians' non-face-to-face (and thus nonreimbursable) elements of care. This article describes a process used in Guilford County, North Carolina, to develop a consensus among health care providers, educators, and child advocates regarding the assessment and treatment of children with symptoms of ADHD. The outcome, ie, a community protocol followed by school personnel and community physicians for >10 years, ensures communication and collaboration between educators and physicians in the assessment and treatment of children with symptoms of ADHD. This protocol has the potential to increase practice efficiency, improve practice standards for children with ADHD, and enhance identification of children in schools. Perhaps most importantly, the community process through which the protocol was developed and implemented has an educational component that increases the knowledge of school personnel about ADHD and its treatment, increasing the likelihood that referrals will be appropriate and increasing the likelihood that children will benefit from coordination of interventions among school personnel, physicians, and parents. The protocol reflects a consensus of school personnel and community health care providers regarding the following: (1) ideal ADHD assessment and management principles; (2) a common entry point (a team) at schools for children needing assessment because of inattention and classroom behavior problems, whether the problems present first to a medical provider, the behavioral health system, or the school; (3) a protocol followed by the school system, recognizing the schools' resource limitations but meeting the needs of community health care providers for classroom observations, psychoeducational testing, parent and teacher behavior rating scales, and functional assessment; (4) a packet of information about each child who is determined to need medical assessment; (5) a contact person or team at each physician's office to receive the packet from the school and direct it to the appropriate clinician; (6) an assessment process that investigates comorbidities and applies appropriate diagnostic criteria; (7) evidence-based interventions; (8) processes for follow-up monitoring of children after establishment of a treatment plan; (9) roles for central participants (school personnel, physicians, school nurses, and mental health professionals) in assessment, management, and follow-up monitoring of children with attention problems; (10) forms for collecting and exchanging information at every step; (11) processes and key contacts for flow of communication at every step; and (12) a plan for educating school and health care professionals about the new processes. A replication of the community process, initiated in Forsyth County, North Carolina, in 2001, offers insights into the role of the AAP ADHD guidelines in facilitating development of a community consensus protocol. This replication also draws attention to identification and referral barriers at the school level. The following recommendations, drawn from the 2 community processes, describe a role for physicians in the collaborative community care of children with symptoms of ADHD. (1) Achieve consensus with the school system regarding the role of school personnel in collecting data for children with learning and behavior problems; components to consider include (a) vision and hearing screening, (b) school/academic histories, (c) classroom observation by a counselor, (d) parent and teacher behavior rating scales (eg, Vanderbilt, Conner, or Achenbach scales), (e) consideration of speech/language evaluation, (f) screening intelligence testing, (g) screening achievement testing, (h) full intelligence and achievement testing if discrepancies are apparent in abbreviated tests, and (i) trials of classroom interventions. (2) Use pediatric office visits to identify children with academic or behavior problems and symptoms of inattention (history or questionnaire). (3) Refer identified children to the contact person at each child's school, requesting information in accordance with community consensus. (4) Designate a contact person to receive school materials for the practice. (5) Review the packet from the school and incorporate school data into the clinical assessment. (6) Reinforce with the parents and the school the need for multimodal intervention, including academic and study strategies for the classroom and home, in-depth psychologic testing of children whose discrepancies between cognitive level and achievement suggest learning or language disabilities and the need for an individualized educational plan (special education), consideration of the "other health impaired" designation as an alternate route to an individualized educational plan or 504 plan (classroom accommodations), behavior-modification techniques for targeted behavior problems, and medication trials, as indicated. (7) Refer the patient to a mental health professional if the assessment suggests coexisting conditions. (8) Use communication forms to share diagnostic and medication information, recommended interventions, and follow-up plans with the school and the family. (9) Receive requested teacher and parent follow-up reports and make adjustments in therapy as indicated by the child's functioning in targeted areas. (10) Maintain communication with the school and the parents, especially at times of transition (eg, beginning and end of the school year, change of schools, times of family stress, times of change in management, adolescence, and entry into college or the workforce).

IQ following treatment of lead poisoning: a patient-sibling comparison.

Forty-seven children treated for lead poisoning (PbB 50 to 365 microgram/dl) were compared to siblings next in age (PbB less than 40 microgram/dl) by a battery of psychologic tests. Symptoms were present in 18 but none had frank encephalopathy. Physical and neurologic examinations revealed no residual damage. Mean psychologic test scores showed no significant difference between patients and controls except in the arithmetic subtest, in which patients' scores were not related to lead concentration. Intelligence tests failed to distinguish children successfully treated from their sibling controls.
