Direct linkWieland, J.; Wardenaar, K. J.; Fontein, E.; Zitman, F. G. – Journal of Intellectual Disability Research, 2012
Background: Diagnostics and care for people with intellectual disabilities (ID) and psychiatric disorders need to be improved. This can be done by using assessment instruments to routinely measure the nature and severity of psychiatric symptoms. Up until now, in the Netherlands, assessment measures are seldom used in the psychiatric care for this…

Frolli, A.; Piscopo, S.; Conson, M. – Journal of Intellectual Disability Research, 2015
Background: Individuals with fragile-X syndrome exhibit developmental delay, hyperexcitation and social anxiety; they also show lack of attention and hyperactivity. Few studies have investigated whether levels of functioning change with increasing age. Here, we explored developmental changes across adolescence in the cognitive and behavioural…

Kanai, Chieko; Tani, Masayuki; Hashimoto, Ryuichiro; Yamada, Takashi; Ota, Haruhisa; Watanabe, Hiromi; Iwanami, Akira; Kato, Nobumasa – Research in Autism Spectrum Disorders, 2012
Little is known about the cognitive profiles of high-functioning Pervasive Developmental Disorders (PDD) in adults based on the Wechsler Intelligence Scale III (WAIS-III). We examined cognitive profiles of adults with no intellectual disability (IQ greater than 70), and in adults with Asperger's disorder (AS; n = 47), high-functioning autism (HFA;…

Gordon, Shirley; Duff, Simon; Davidson, Terry; Whitaker, Simon – Journal of Applied Research in Intellectual Disabilities, 2010
Background: 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…

Silverman, Wayne; Miezejeski, Charles; Ryan, Robert; Zigman, Warren; Krinsky-McHale, Sharon; Urv, Tiina – Intelligence, 2010
Stanford-Binet and Wechsler Adult Intelligence Scale (WAIS) IQs were compared for a group of 74 adults with intellectual disability (ID). In every case, WAIS Full Scale IQ was higher than the Stanford-Binet Composite IQ, with a mean difference of 16.7 points. These differences did not appear to be due to the lower minimum possible score for the…

Umphress, Thomas B. – Intellectual and Developmental Disabilities, 2008
Twenty people with suspected intellectual disability took the Reynolds Intellectual Assessment Scales (RIAS; C. R. Reynolds & R. W. Kamphaus, 1998) and the Wechsler Adult Intelligence Scale--3rd Edition (WAIS-III; D. Wechsler, 1997) to see if the 2 IQ tests produced comparable results. A t test showed that the RIAS Composite Intelligence Index…

Rossi, N. F.; Giacheti, C. M. – Journal of Intellectual Disability Research, 2017
Background: Williams syndrome (WS) phenotype is described as unique and intriguing. The aim of this study was to investigate the associations between speech-language abilities, general cognitive functioning and behavioural problems in individuals with WS, considering age effects and speech-language characteristics of WS sub-groups. Methods: The…

Williams, Tricia S.; Westmacott, Robyn; Dlamini, Nomazulu; Granite, Leeor; Dirks, Peter; Askalan, Rand; MacGregor, Daune; Moharir, Mahendranath; Deveber, Gabrielle – Developmental Medicine & Child Neurology, 2012
Aim: Moyamoya vasculopathy is characterized by progressive stenosis of the major arteries of the Circle of Willis, resulting in compromised cerebral blood flow and increased risk of stroke. The objectives of the current study were to examine intellectual and executive functioning of children with moyamoya and to evaluate the impact of moyamoya…

Temple, V.; Drummond, C.; Valiquette, S.; Jozsvai, E. – Journal of Intellectual Disability Research, 2010
Background: Video conferencing (VC) technology has great potential to increase accessibility to healthcare services for those living in rural or underserved communities. Previous studies have had some success in validating a small number of psychological tests for VC administration; however, VC has not been investigated for use with persons with…

Munoz-Ruata, J.; Caro-Martinez, E.; Perez, L. Martinez; Borja, M. – Journal of Intellectual Disability Research, 2010
Background: Perception disorders are frequently observed in persons with intellectual disability (ID) and their influence on cognition has been discussed. The objective of this study is to clarify the mechanisms behind these alterations by analysing the visual event related potentials early component, the N1 wave, which is related to perception…

Hayes, Susan; Shackell, Phil; Mottram, Pat; Lancaster, Rachel – British Journal of Learning Disabilities, 2007
Over-representation of people with learning disability in prisons has been demonstrated in many Western jurisdictions. This was the first comprehensive research in a UK prison. The research used a random 10% sample of a prison population (n = 140). A semi-structured interview, the Wechsler Adult Intelligence Scale-III (UK version) and the Vineland…

Sondenaa, E.; Rasmussen, K.; Palmstierna, T.; Nottestad, J. – Journal of Intellectual Disability Research, 2008
Background: The objective of the study was to calculate the prevalence of inmates with intellectual disabilities (ID), and identify historical, medical and criminological characteristics of a certain impact. Methods: A random sample of 143 inmates from a Norwegian prison cross sectional sample was studied. The Hayes Ability Screening Index (HASI)…

Copet, P.; Jauregi, J.; Laurier, V.; Ehlinger, V.; Arnaud, C.; Cobo, A. -M.; Molinas, C.; Tauber, M.; Thuilleaux, D. – Journal of Intellectual Disability Research, 2010
Background: Prader-Willi syndrome (PWS) is a rare genetic disorder characterised by developmental abnormalities leading to somatic and psychological symptoms. These include dysmorphic features, impaired growth and sexual maturation, hyperphagia, intellectual delay, learning disabilities and maladaptive behaviours. PWS is caused by a lack of…

Fitzgerald, Suzanne; Gray, Nicola S.; Snowden, Robert J. – Journal of Applied Research in Intellectual Disabilities, 2007
Background: Whether the Flynn effect (the increase in the populations' IQ over time) affects the IQ scores of people with learning disability or borderline learning disability remains unclear. The issue is important as the Flynn effect should alter the number of people eligible for health service resources. A comparison of the Wechsler Adult…
