چکیده

The present investigation compared the North American Adult Reading Test (NAART), Wide Range Achievement Test-3 (WRAT-3) Reading subtest, Barona, and Oklahoma Premorbid Intelligence Estimate Best (OPIE) premorbid intelligence estimates in 64 chronic pain patients across three intelligence ranges. Results for the entire sample revealed that the NAART, Barona, and OPIE Best equations overestimated Wechsler Adult Intelligence Scale-Revised Full Scale IQ (WAIS-R FSIQ), while the WRAT-3 underestimated FSIQ. When the sample was divided into three intelligence ranges, the OPIE more accurately classified individuals with above average intelligence, while the WRAT-3 more accurately classified individuals with below average intelligence. Three methods (NAART, OPIE, and WRAT-3) provided relatively equivalent classifications of individuals in the average intelligence range. The Barona method tended to systematically under- and overestimate FSIQ across the intelligence continuum. These results suggest the potential utility of using different estimation methods for individuals in different IQ ranges, and speak to the need for development of estimation methods that incorporate current reading ability with best performance and demographic variables.

The National Adult Reading Test as a measure of premorbid intelligence: a comparison with estimates derived from demographic variables.

Since its publication in 1982, the National Adult Reading Test (NART; Revised Version, NART-R) has become a widely accepted method for estimating premorbid levels of intelligence in neuropsychological research. However, the assumption that NART/NART-R performance is relatively independent of brain damage has been increasingly challenged in recent years. In a number of conditions, including Alzh...

Estimating Premorbid Intelligence among Older Adults: The Utility of the AMNART

This study examines the utility of the American version of the National Adult Reading Test (AMNART) as a measure of premorbid intelligence for older adults. In a sample of 130 older adults, aged 56 to 104, the AMNART was compared to other tests of premorbid intelligence. The results revealed that AMNART-estimated IQ was significantly higher than other premorbid estimates. Across specific educat...

Isogeometric Topology Optimization of Continuum Structures using an Evolutionary Algorithm

Topology optimization has been an interesting area of research in recent years.  The main focus of this paper is to use an evolutionary swarm intelligence algorithm to perform Isogeometric Topology optimization of continuum structures.  A two-dimensional plate is analyzed statically and the nodal displacements are calculated.  The nodal displacements using Isogeometric analysis are found to be ...

A COMPARATIVE STUDY OF TRADITIONAL AND INTELLIGENCE SOFT COMPUTING METHODS FOR PREDICTING COMPRESSIVE STRENGTH OF SELF – COMPACTING CONCRETES

This study investigates the prediction model of compressive strength of self–compacting concrete (SCC) by utilizing soft computing techniques. The techniques consist of adaptive neuro–based fuzzy inference system (ANFIS), artificial neural network (ANN) and the hybrid of particle swarm optimization with passive congregation (PSOPC) and ANFIS called PSOPC–ANFIS. Their perf...

Estimating Premorbid Intelligence by Combining the Nart and Demographic Variables: an Examination of the Nart Standardisation Sample and Supplementary Equations

There are two main approaches to the-estimation of premorbid intelligence. One of these uses an oral reading test, the National Adult Reading Test (NART). The other estimates premorbid intelligence from demographic variables. It was recently reported that combining the NART and demographic variables in a multiple regression equation provides more accurate estimation of IQ than is afforded by ei...
