Background: Assessment of intelligence and executive function (EF) is common in complex neuropsychiatric practice. Although previous studies have shown that EF and intelligence are related, it is unknown whether these constructs relate to one another in a similar manner across different ability groups (mild intellectual disability, borderline…

A known-groups design was used to determine the classification accuracy of Wechsler Adult Intelligence Scale-III (WAIS-III) variables in detecting malingered neurocognitive dysfunction (MND) in traumatic brain injury (TBI). TBI patients were classified into the following groups: (a) mild TBI not-MND (n = 26), (b) mild TBI MND (n = 31), and (c)…

Wechsler Memory Scale Memory Quotient (WMS MQ) 12 points below Wechsler Adult Intelligence Scale Full-Scale IQ (WAIS FSIQ) may indicate memory impairment. Investigated the relation of FSIQ to MQ when the Wechsler Adult Intelligence Scale-Revised rather than the WAIS is used. Discrepancy between FSIQ and MQ occurred less often with WAIS-R than with…

The General Ability Index (GAI) was compared with Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) Full Scale Intelligence Quotient (FSIQ) from the WAIS-III in data obtained from 381 adults assessed for reported learning or attention problems between 1998 and 2005. Not only did clients with more neurocognitively based disorders (i.e.,…

The Kaufman Brief Intelligence Test (K-BIT) (A. S. Kaufman and N. L. Kaufman, 1990) was compared with short forms of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) using results from 64 referrals to a neuropsychology service. Advantages of each test are noted and their use discussed. (SLD)

Seven different short forms of the Wechsler Adult Intelligence Scale, Revised (WAIS-R) were compared in a mixed clinical sample of 306 adults to evaluate short form predictions of the full scale IQ. The seven-test short form of C. Ward (1990) was the best predictor across ranges of intellectual functioning, supporting its use when time is limited.…

Three short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), developed in 1991, were cross-validated on 207 male and 133 female adolescent psychiatric inpatients and outpatients. Results show psychometric properties for the short forms that are comparable to those of the WAIS-R standardization sample. (SLD)

Background: Prader-Willi syndrome (PWS) is associated with a characteristic behavioural phenotype whose main features are, alongside compulsive hyperphagia, deficits in social behaviour: social withdrawal, temper tantrums, perseverative speech and behaviour, mental rigidity, stereotyped behaviour, impulsiveness, etc. Similar symptoms may also be…

Background: Childhood onset schizophrenia (COS) is a rare disorder. Comparative data on the effect of differential age of onset on clinical profile in schizophrenia are very few. Method: Subjects with COS (n = 15), adolescence onset schizophrenia (AdOS, n = 20) and adulthood onset schizophrenia (AOS, n = 20) were compared on socio-demographic,…
