Test Validity and Performance Validity: Considerations in Providing a Framework for Development of an Ability-Focused Neuropsychological Test Battery.
Abstract Literature on test validity and performance validity is reviewed to propose a framework for specification of an ability-focused battery (AFB). Factor analysis supports six domains of ability: first, verbal symbolic; secondly, visuoperceptual and visuospatial judgment and problem solving; thirdly, sensorimotor skills; fourthly, attention/working memory; fifthly, processing speed; finally, learning and memory (which can be divided into verbal and visual subdomains). The AFB should include at least three measures for each of the six domains, selected based on various criteria for validity including sensitivi...

The multiple validities of neuropsychological assessment.
This article discusses construct and criterion validity of neuropsychological tests, as well as assessment validity, which allows determination of whether an individual examinee is producing valid test results. Factor analyses identify 6 domains of abilities. Tests of learning and memory and processing speed are most sensitive to presence of brain dysfunction in both traumatic brain injury (TBI) and Alzheimer's disease (AD). Tests of processing speed, working memory, verbal symbolic functions, and visuoperceptual and visuospatial judgment and problem solving are sensitive to the severity of TBI and AD, as well as to the fu...

The relationship of cognitive change over time to the self-reported Ascertain Dementia 8-item Questionnaire in a general population.
CONCLUSIONS: Incident cognitive impairment and high depression risk were the strongest predictors of self-reported positive AD8 in this population-based sample. Our results inform the utility of the AD8 as a self-report measure in a large, national sample that avoids selection biases inherent in clinic-based studies. The AD8 is screening measure and should not be used to diagnose dementia clinically. PMID: 32613226 [PubMed - as supplied by publisher]
