test of premorbid functioning iq

Individuals screened for dementia vary widely in premorbid IQ, with implications for the interpretation of performance on cognitive screening tests. A revised and updated version of the Wechsler Test of Adult Reading™ (WTAR), the Test of Premorbid Functioning (TOPF) enables clinicians to estimate an individual’s level of cognitive and memory functioning before the onset of injury or illness.

Premorbid intelligence has commonly been estimated using “hold tests,” which are neuropsychological measures that are relatively unaffected by most forms of neuropathological change, therefore able to “hold” an individual's level of functioning (Russell, 1980). The Barona equation estimated higher premorbid IQ than TOPF Simple Demographics Model; however, differences between the models were nonsignificant after a Flynn effect correction for the Barona equation (.23 IQ points per year). The present study compared estimates obtained from these measures in a neurodegenerative disease population. Outpatient neuropsychological … Premorbid intelligence is an estimate of a person’s intellectual functioning prior to known or suspected onset of brain disease or dysfunction. Paired sample t tests assessed differences between IQ models. 2020 May 14:acaa025. Get instructions and help on ordering from our product catalogue. Mean differences were evaluated to establish how closely the models approximated WAIS-IV FSIQ. Conclusion:  |  COVID-19 is an emerging, rapidly evolving situation. 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. Premorbid IQ in dementia is hard to measure as it requires a test that is both highly associated with current IQ in individuals without dementia and robust to the effects of dementia. Definition. Objective: Online ahead of print. (WAIS-IV). Three of the most researched approaches to estimating premorbid ability are reading tests, “hold” versus “don’t hold” tests and demographic regression equations.
