The stability of IQ in people with low intellectual ability: an analysis of the literature
No full textA meta-analysis of the stability of low IQ (IQ 80) was performed on IQ tests that have been
commonly used—tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997)
and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-
mean stability coefficients of .77 and .78 were found for Verbal IQ (V IQ) and Performance IQ
(P IQ) on the Wechsler tests and .82 for Full-Scale IQ (FS IQ) on both Wechsler and Binet tests,
for a mean test–retest interval of 2.8 years. Although the majority of FS IQs changed by less than
6 points, 14% changed by 10 points or more. The author suggests that the results of IQ assessment
should be treated with more caution than previously thought

Aufbau: Die WMS-R besteht aus 13 Subtests, wobei die Untertests 10-13 die Items von (5)-(7) erneut abrufen: (1) Information und Orientierung, (2) Mentale Kontrolle, (3) Figurales Gedächtnis, (4) Logisches Gedächtnis I (Textreproduktion I), (5) Visuelle Paarerkennung I, (6) Verbale Paarerkennung I, (7) Visuelle Wiedergabe I, (8) Zahlenspanne, (9) Visuelle Merkspanne, (10) Logisches Gedächtnis II, (11) Visuelle Paarerkennung II, (12) Verbale Paarerkennung II, (13) Visuelle Wiedergabe II. Folgende Summenwerte werden gebildet: Verbales Gedächtnis (Subtests 4 und 6), Visuelles Gedächtnis (Subtests 3, 5 und 7), Aufmerksamkeit/Konzentration (Subtests 2, 8 und 9), Verzögerte Wiedergabe (Subtests 10-13). Außerdem wird ein Wert für "Allgemeines Gedächtnis" aus den Summenwerten des verbalen und des visuellen Gedächtnisses bestimmt. Grundlagen und Konstruktion: Die Wechsler Memory Scale wurde nach 10-jähriger Erprobungszeit von David Wechsler 1945 veröffentlicht und war in der Folgezeit als der am weitesten verbreitete Gedächtnistest anzusehen. Um das visuelle Gedächtnis und das Langzeitgedächtnis stärker zu berücksichtigen sowie zwischen unterschiedlichen Gedächtnisfunktionen zu differenzieren, führte Wechsler in den 70er und 80er Jahren eine Revision des Tests durch, wobei drei neue Subtests erstellt und erprobt (Figurales Gedächtnis, Visuelle Paarerkennung, Visuelle Merkspanne) sowie die Wiedererkennungs-Untertests konzipiert wurden (Wechsler, 1987). Gegenüber der amerikanischen Revision wurde für die deutsche Adaptation der Untertest Visuelle Merkspanne leicht verändert. Die Gewichtung der verschiedenen Untertests wurde aus dem amerikanischen Original übernommen, jedoch eine neue Computerprozedur zur Errechnung der Indexnormen entwickelt. Empirische Prüfung und Gütekriterien: Reliabilität: Die Retestreliabilitäten (6 Monate, 40 Persoen aus allen Altersgruppen) lagen auf Subtestebene zwischen .42 und .83, auf Indexebene ergaben sich Stabilitätskoeffizienten von .80 bis .88. Validität: Das Verfahren besitzt inhaltlich-logische Gültigkeit. Es zeigten sich deutliche Leistungsunterschiede in den Gedächtnisindizes bei verschiedenen Hirnschädigungen. Kognitive Beeinträchtigungen aufgrund einer depressiven Erkrankung ließen sich von solchen aufgrund einer beginnenden Alzheimer Demenz abgrenzen und es ließ sich ein kritischer Cut-off-Wert errechnen. Normen: Normwerte (IQ-Äquivalente, M = 100, SD = 15 und Prozentränge) liegen von einer repräsentativen Stichprobe (N = 210) für sieben Altersgruppen (15-74 Jahre) getrennt vor.publishedVersio

Adaptations and accommodations: The use of the WAIS III with people with a Learning Disability
No full textEvidence of significant impairment in cognitive functioning has always been one of the main criteria of a learning disability (Pulsifer, 1996) and intellectual assessment is, therefore, one of the tasks of clinical psychologists working within learning disability services. Such assessments are commonly used to help establish of an individual’s cognitive strengths and weaknesses, support needs and more specifically, to help determine if an individual falls within the remit of learning disability services (McKenzie & Murray, 2002, Evers & Hill, 1999). Intellectual assessments also have important implications in terms of mental health legislation, accessing benefits and services and informing legal decision-making processes (British Psychological Society, 2001, McKay, 1991). It is, therefore, crucial that the assessments are valid, reliable and used only by appropriately trained and qualified professionals. In Britain, it is emphasised that assessing an individual’s intellectual functioning requires an individually administered, standardised psychometric assessment which is reliable and valid (British Psychological Society, 2001), while in America professional mandates, such as the Standards for Educational and Psychological Testing (AERA,APA & NCME, 1985) highlight the need for high standards of administrative accuracy from psychologists.
The Wechsler Adult Intelligence Scales - Third Edition (Wechsler, 1998) are commonly used in intellectual and neuropsychological assessment and are considered to be valid, reliable and well-standardised (Groth-Marnat et al, 2000). The Wechsler Scales have a long history and have undergone a number of revisions with the most recent being in 1997 with the development of the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III). The purpose of these revisions was to insure that the standardisation sample was representative of current demographics and performance, to update the subtests, incorporate new subtests, and refine the instructions and test materials. Each revision has been well researched and validated (Groth Marnat et al, 2000)
A pilot of the use of the WAIS III in learning disability services
No full textThe present study is a pilot examining how a group of people (n=133) with a learning disability perform on the Wechsler Adult Intelligence Scale – Third Edition (1997). The study found that Full Scale IQ was not always predictive of performance on individual subtests or of performance on the Indices. Implications for clinical practice are discussed
Comparison of the WAIS-III and WISC-IV in 16-Year-Old Special Education Students
No full textBackground Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale – Third Edition (WAIS-III) with the Wechsler Intelligence Scale for Children – Fourth Edition (WISC-IV) was conducted with individuals who were 16 years old and receiving special education.
Materials and Methods All participants completed the WAIS-III (UK) and WISC-IV (UK). The order of administration was counterbalanced; the mean Full Scale IQ and Index scores on the WAIS-III and WISC-IV were compared.
Results The WAIS-III mean Full Scale IQ was 11.82 points higher than the mean Full Scale IQ score on the WISC-IV. Significant differences were also found between the Verbal Comprehension Index, Perceptual Reasoning/Organization Index and Processing Speed Index on the WAIS-III and WISC-IV, all with the WAIS-III scoring higher.
Conclusions The findings suggest that the WAIS-III produces higher scores than the WISC-IV in people with intellectual disabilities. This has implications for definitions of intellectual disability and suggests that Psychologists should be cautious when interpreting and reporting IQ scores on the WAIS-III and WISC-IV

Further validation of the New Zealand test of adult reading (NZART) as a measure of premorbid IQ in a New Zealand sample
No full textPremorbid IQ estimates are used to determine decline in cognitive functioning following trauma or illness. This study aimed to: 1) further validate the New Zealand Adult Reading Test (NZART) in a New Zealand population and compare its performance to the UK developed National Adult Reading Test, and 2) develop regression formulae for the NZART to estimate Wechsler Adult Intelligence Scale-IV (WAIS–IV) IQ scores. The 67 participants (53 females; 16 Māori), aged 16 to 90 years old (mean age = 46.07, SD 23.21) completed the WASI-IV, the NART and the NZART. The NZART predicted Verbal Comprehension Index (VCI) scores slightly better than the NART (r =.63 vs. r = .62) and explained 33% of the variance in FSIQ scores. Reasons for developing regression formulae for the NZART are discussed, regression formulas for the NZART based on the WAIS–IV are included and suggestions of alternate ways of determining premorbid IQ are made
