Abstract Neuropsychological tests are routinely used to assess Māori, the indigenous people of New Zealand, yet very few investigations of the psychometric properties of these tests with this population have been conducted. This paper focuses on factors that may impact performance of Māori adults on neuropsychological testing. The Wechsler Adult Intelligence Scale-IV (WAIS-IV) was administered to a sample of 284 Māori stratified for age (between 16 years and 90 years) and gender in order to establish a Māori normative data set. The sample who primarily spoke English as their first language were recruited from a range of urban, regional and rural areas in New Zealand to obtain representation of the main Māori Iwi (tribes). Analysis of test results suggests acculturation, education, income, and, “a culturally positive experience” may have accounted for some of the variance in test performance.

Wechsler Adult Intelligence

Abstract Objective Working memory assessment is an important component of a neuropsychological evaluation. The Paced Auditory Serial Addition Task (PASAT) and the Wechsler Adult Intelligence Scale – Third Edition Letter Number Sequencing subtest (LNS) are two commonly used measures of working memory. Demographic variables (age, education, ethnicity, and country of origin) can impact performance on these measures, underscoring the need for demographically adjusted norms when utilizing these tests. We aimed to develop normative data for the PASAT and LNS for Spanish-speaking adults living in the US. Participants and Method The PASAT and LNS were administered to Spanish-speaking adults living in the US-Mexico border regions of California and Arizona as part of a larger normative effort in this population. Two hundred and forty-nine participants completed the PASAT and a subset (n = 202) also completed LNS. Ages ranged from 19-60 and education from 0-20 years. Results Older age was associated with lower scores on LNS (p < .01), but not the PASAT. Lower education was associated with lower scores on both tests (ps < .001). Females obtained lower raw scores than males on the PASAT (ps < .003), and there were no significant main effects of gender on LNS raw scores. Raw-to-scaled score conversions were calculated for the PASAT-50 item, PASAT-200 item, and LNS, and fractional polynomial equations were developed to calculate demographically-adjusted T-scores accounting for age, education, and gender. Published norms for English-speaking non-Hispanic Whites drastically overestimated rates of impairment (defined as T-score < 40) on both the PASAT and LNS. Conclusions The use of the population-specific normative data may improve detection of working memory dysfunction in Spanish-speaking adults living in the US and contribute to improved diagnostic accuracy and treatment planning in this population.

AbstractIntroduction: A wealth of evidence indicates that neurocognitive deficits are evident in patients with schizophrenia at both illness onset and after many years of treatment. Little is known regarding if or how these deficits change during the lifespan. The goal of the study was to evaluate changes in full-scale intelligence quotient and neurocognitive test performance over a 10-year interval in patients with schizophrenia.Methods: Twelve patients were administered the Wechsler Adult Intelligence Scale-Revised as a measure of intellectual function and a neuropsycshological test battery including measures of attention, verbal and nonverbal memory, language, visuospatial function, problem-solving, and motor function at entry to the study and at a 10-year follow-up.Results: With the exception of performance on a measure of speeded motor sequencing, there was no significant decline in any of the measures at 10-year follow-up. Results from a measure of sustained auditory attention showed improvement at follow-up.Discussion: These data support a neurodevelopmental model of schizophrenia for young adult to middle-age patients by suggesting that neurocognitive deficits that emerge either before disease onset or early in the course of the illness remain stable as the patient ages.Conclusion: Overall, measures of intelligence quotient as well as specific neurocognitive skills, do not decline over a 10-year period in at least a subgroup of patients with schizophrenia.

This study examined the effect of contingent verbal reinforcement upon the intelligence test performance of adults high and low in anxiety. 60 white undergraduates were divided into groups of 30 of high anxiety and 30 of low anxiety on the basis of their IPAT Anxiety Scale scores. Each examinee received the Quick Test as a premeasure of intelligence and then the Wechsler Adult Intelligence Scale under experimental conditions. 15 subjects with low and 15 subjects with high anxiety received verbal reinforcement after each correct response on the WAIS, while another 15 in each group performed under standard testing conditions. Results were not consistent with previous findings in that WAIS Full Scale, Verbal, and Performance IQs were not significantly affected by reinforcement condition or anxiety level.

Diese Studie untersucht die Zusammenhänge von Intelligenz- und Gedächtnisleistungen in der Wechsler Adult Intelligence Scale-IV und der Wechsler Memory Scale-IV unter Berücksichtigung des Geschlechts (N = 137 Gesunde, 63 w/74 m). Ein Vorteil der weiblichen Testpersonen im verbalen episodischen Gedächtnis sowie in einzelnen Aufgaben zur Verarbeitungsgeschwindigkeit konnte beobachtet werden. Die männlichen Testpersonen schnitten in den Untertests Allgemeines Wissen und Visuelle Puzzles besser ab. Wie gut Gedächtnisleistungen Intelligenzleistungen erklären beziehungsweise vorhersagen, ist aufgrund unserer Ergebnisse nicht nur abhängig von den Aufgaben, sondern auch vom Geschlecht.

Im vorliegenden Beitrag wird der Datensatz (N = 1664), aus dem auch die Normstichprobe für die deutschsprachige Version der Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV) gezogen wurde, nach altersabhängigen Veränderungen kognitiver Fähigkeiten analysiert. Die niedrigsten Rohwertmittelwerte werden in der ältesten Altersgruppe erreicht, die Leistungsspitzen finden sich überwiegend im Altersbereich zwischen 20 und 29 Jahren. In den Untertests der Indizes Wahrnehmungsgebundenes Logisches Denken und Verarbeitungsgeschwindigkeit kommt es zu einer bedeutsamen Leistungsabnahme mit zunehmendem Alter: In der ältesten Altersgruppe werden nur noch zwischen 50 und 60 % der Rohwertmittelwerte der leistungsstärksten Altersgruppe erreicht. Gleichzeitig nimmt die Heterogenität in der Rohwertverteilung zu. Für die Indizes Sprachverständnis und Arbeitsgedächtnis fallen beide Effekte deutlich niedriger aus.

AbstractSerum alpha-klotho (s-klotho) protein has been linked with lifespan, and low concentrations of s-klotho have been associated with worse physical and cognitive outcomes. Although its significance in aging remains unclear, s-klotho has been proposed as a molecular biomarker of frailty and dependence. This study is a secondary analysis of data from a clinical trial performed in a population of 103 older individuals living in 10 nursing homes in Gipuzkoa (Spain). We aimed to elucidate associations between s-klotho (as measured by enzyme-linked immunosorbent assay) and body composition, physical fitness, and cognition, as well as frailty and dependence (determined using validated tests and scales). In addition, we investigated the association of s-klotho concentration with falls in the six months following the initial assessment. Low s-klotho levels were associated with a lower score in the psychological component of the Tilburg Frailty Indicator, a worse score in the Coding Wechsler Adult Intelligence Scale, and a greater dependence in activities of daily living. Moreover, participants with lower s-klotho concentrations suffered more falls during the 6 months after the assessment. Future translational research should aim to validate klotho’s putative role as a biomarker that could identify the risk of aging-related adverse events in clinical practice.

Intelligence Scores

The present study examined associations between Wechsler Adult Intelligence Scale–Revised (WAIS–R) scores and the five-factor model of personality, as measured by the Revised NEO Personality Inventory. Both tests were administered to a nonclinical sample of 100 Italian subjects 75 years and older. Analysis showed that the NEO-PI–R Openness to Experience domain was a weak but the best predictor of the three WAIS–R intelligence scores (Total, Verbal, and Performance). Were such a relationship confirmed by further investigations, Openness could be interpreted as a factor which might mitigate intellectual impoverishment which accompanies the normal aging process.
