Ninety-one males with schizophrenia or schizoaffective disorder were examined. Estimations of premorbid functioning typically are based on performance on tasks that are not affected by cognitive change or on demographic comparisons.

Objectives: To assess the robustness of the TOPF against the Spot-the-Word (version 2; STW-2) and a demographic regression equation in estimating premorbid ability in people with Alzheimer’s disease (AD), vascular dementia (VD) and mixed dementias (AVD). This assessment is conducted by an interviewer who has undergone a 4-month training course.13,14 The assessment of males includes a structured interview assessing behavioral functioning, including social functioning—the ability to make and keep friends, social adeptness, and ability to achieve social closeness and functioning in structured environments, such as school or work. Although previous studies have operated under the assumption that word reading tests are valid and stable indicators of premorbid abilities in HIV infection, studies of other populations have found that this is not always the case. This study investigated the ability of the National Adult Reading Test (NART), the Wechsler Test of Adult Reading (WTAR), and the Test of Premorbid Functioning (TOPF) to predict premorbid IQ. The reliability and validity of these measures have been extensively tested by the Draft Board, and population-based norms are available for each of the tests.13,14 For the purposes of the current study, the Draft Board assessment was administered again alongside the PAS. Is the Test of Premorbid Functioning a Valid Measure for Maori in New Zealand @article{Dudley2017IsTT, title={Is the Test of Premorbid Functioning a Valid Measure for Maori in New Zealand}, author={Margaret Dudley and K. Scott and S.

This new assessment tool is: An effective method for predicting full-scale IQ and memory performance Most of these scales, however, were developed a number of years ago (1941–1974) and fail to evaluate premorbid functioning systematically at several life periods.6 In addition, an extended range of correlations was found between total scores of premorbid measures (variance range 20%–80%), suggesting that each instrument appears to measure unique aspects of premorbid adjustment.7 The Premorbid Adjustment Scale (PAS), developed by Cannon-Spoor et al,6 is a compilation of items from past scales and was developed as a research instrument.8. Premorbid intelligence is an estimate of a person’s intellectual functioning prior to known or suspected onset of brain disease or dysfunction. While there is a wealth of research into the Flynn effect, as yet no research exists examining the effect on tests of premorbid functioning. Oxford University Press is a department of the University of Oxford. (2015) To the best of our knowledge, this is the first study to use information, originally obtained prior to first psychotic episode, to validate PAS ratings based on retrospective reports and data obtained contemporaneously on another validated measure. 6 The PAS is a 26-item rating scale that includes measures of social isolation, peer relationships, functioning outside of the family, and school functioning at 4 age periods (up to age 11, 12–15, 16–18, and 19 years and above) as well as social-sexual aspects of life starting at … Performance is scored on a 7-point scale ranging from 0 (healthiest adjustment) to 6 (lowest adjustment).

Keywords: Wechsler Adult Intelligence Scale, Test of Premorbid Functioning (TOPF), malingering, effort, performance validity, excessive decline In summary, the results of the current study support the predictive and concurrent validity of the PAS completed based on self-report data and therefore increase the confidence in utilizing this instrument in clinical and research settings. Outpatient neuropsychological … Conclusions: Our results support the predictive and concurrent validity of the PAS and the validity of self-reported data on premorbid functioning in persons with schizophrenia. Background: The aim of the current study was to test the predictive and concurrent validity of the Premorbid Adjustment Scale (PAS) by comparing it with another similar but more elaborate retrospective measure and with data collected during late adolescence. For permissions, please email: [email protected]. Clinicians should exercise caution when interpreting the results of reading tests by considering and reporting the confidence intervals for obtained-minus-predicted IQ discrepancies and with clear reference to the clinical history and other cognitive test results. The study was approved by the local institutional review board, and all participants gave informed written consent. The literature is … The current study supports the validity of the PAS and supports the use of the PAS based on self-report data of persons with schizophrenia. Although the diagnosis of schizophrenia and spectrum disorders in psychiatric hospitals in Israel has been shown to be congruent with research diagnosis,11 we also administered the Structured Clinical Interview for DSM IV Axis I Disorders, Research Version, Non patient Edition12 to a randomly selected one-third of the sample. Results: The correlation of the PAS social withdrawal and social relations items with the social behavior scale of the Draft Board were .76 and .80, respectively, for the concurrent ratings and .52 and .53, respectively, for the data collected at age 17 years. Previous studies have reported mixed results on the validity of reading tests in people with dementia, and the TOPF has yet to be investigated as to how well it holds in dementia. 3. Part II. (1988). Psychology. Methods: Thirty patients with an ICD-10 diagnosis of probable AD, VD or ADV were recruited from two NHS Older Adult Community Mental Health teams and their scores on the TOPF, STW-2 and a demographic equation were compared with thirty healthy matched controls. Another limitation was that the sample was in remission and had a relatively low level of positive symptoms (mean = 11.3, SD = 5.53). National Alliance for Research on Schizophrenia and Depression (Young Investigator Award to M.W. The Test of Premorbid Functioning enables clinicians to estimate an individual’s level of cognitive and memory functioning before the onset of injury or illness. Introduction: The Test of Premorbid Functioning (TOPF) is a relatively new reading test designed to estimate premorbid intelligence in people with a diagnosed or suspected dementia. Objective: This study examined premorbid ability estimate concordance using Test of Premorbid Functioning predicted Full Scale Intelligent Quotient (TOPF-IQ) and Wide Range Achievement Test–Fourth Edition Word Reading (WRAT4-WR).Method: The sample (N = 145) was 28% female with average age and education of 40.6 and 13.2 years, respectively.

Despite its widespread use in research, relatively little is known about the reliability and validity of the instrument.8,9 The aim of the current study was to test the validity of this instrument. Using the ACS Test of Premorbid Functioning (TOPF) The TOPF is part of the Advanced Clinical Solutions (ACS: Pearson, 2009) for the WAIS–IV/WMS–IV. A discrepancy between premorbid and current functioning is indicative of cognitive decline. To examine concurrent validity, correlations were calculated between PAS and the current readministration of the Draft Board assessment in which participants were asked about themselves at age 16–17 years.

The observed pattern of associations supports the validity of PAS late adolescence (age 16–18 years) scores in estimating premorbid functioning in persons with schizophrenia, as well as the validity of the separate social and school functioning scales of the PAS. Assessing the robustness of the Test of Premorbid Functioning (TOPF) as a measure of premorbid intelligence in Alzheimer’s and vascular dementia and clinical research portfolio. The method for predicting premorbid functioning is empirically validated, psychometrically based, reproducible across evaluators, and derived from data that are relatively impervious to invalidity (e.g., demographic information). The demographic equation provided a significantly higher estimation of IQ than both of the reading tests for people with a dementia. ); German Federal Ministry of Education and Research (BMBF) within the framework of German Israeli Project Cooperation (to J.R.); Elie Wiesel Chair (to J.R.); Hanacy Scholarship Bar Ilan University (to N.B.).

For the purpose of the current study, we administered the PAS to individuals who as adults were diagnosed with schizophrenia. A discrepancy between premorbid and current functioning is indicative of cognitive decline. The current study results strongly support the predictive and concurrent validity of the PAS social and school functioning items for late adolescence. All rights reserved. The PAS is frequently used for assessment of premorbid social and school functioning in persons with schizophrenia.
