Detecting Feigning on the Montreal Cognitive Assessment (MoCa): Development of an Embedded Performance Validity Test
Direct linkDirect link
Paige Haley – ProQuest LLC, 2023
As the research on feigning has grown, the number and quality of performance validity tests (PVTs) has increased as well. However, while several PVTs have been developed from assessments commonly used as part of neuropsychological batteries, there has been less exploration for PVTs scored from items in cognitive screeners. The Montreal Cognitive…

Janssen, Nikki; Roelofs, Ardi; van den Berg, Esther; Eikelboom, Willem S.; Holleman, Meike A.; in de Braek, Dymphie M. J. M.; Piguet, Olivier; Piai, Vitória; Kesselsa, Roy P. C. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: The three variants of primary progressive aphasia (PPA) differ in clinical presentation, underlying brain pathology, and clinical course, which stresses the need for early differentiation. However, brief cognitive tests that validly distinguish between all PPA variants are lacking. The Sydney Language Battery (SYDBAT) is a promising…

Dowling, N. Maritza; Raykov, Tenko; Marcoulides, George A. – Educational and Psychological Measurement, 2020
Equating of psychometric scales and tests is frequently required and conducted in educational, behavioral, and clinical research. Construct comparability or equivalence between measuring instruments is a necessary condition for making decisions about linking and equating resulting scores. This article is concerned with a widely applicable method…

Dementia in People with Severe/Profound Intellectual (and Multiple) Disabilities: Applicability of Items in Dementia Screening Instruments for People with Intellectual Disabilities
Peer reviewed Peer reviewed

Wissing, Maureen B. G.; Dijkstra, Roos; van der Wal, Ina A.; Grootendorst, Esther S.; Hobbelen, Johannes S.M.; van der Putten, Annette A. J.; De Deyn, Peter P.; Waninge, Aly; Dekker, Alain D. – Journal of Mental Health Research in Intellectual Disabilities, 2022
Introduction: Diagnosing dementia in people with severe/profound intellectual (and multiple) disabilities (SPI(M)D) is complex. Whereas existing dementia screening instruments as a whole are unsuitable for this population, a number of individual items may apply. Therefore, this study aimed to identify applicable items in existing dementia…

Language Decline Characterizes Amnestic Mild Cognitive Impairment Independent of Cognitive Decline
Peer reviewed Peer reviewed

Sherman, Janet Cohen; Henderson, Charles R.; Flynn, Suzanne; Gair, James W.; Lust, Barbara – Journal of Speech, Language, and Hearing Research, 2021
Purpose: This research investigated the nature of cognitive decline in prodromal Alzheimer's disease (AD), particularly in mild cognitive impairment, amnestic type (aMCI). We assessed language in aMCI as compared with healthy aging (HA) and healthy young (HY) with new psycholinguistic assessment of complex sentences, and we tested the degree to…

Haque, Rafi U.; Manzanares, Cecelia M.; Brown, Lavonda N.; Pongos, Alvince L.; Lah, James J.; Clifford, Gari D.; Levey, Allan I. – Learning & Memory, 2019
The entorhinal-hippocampal circuit is one of the earliest sites of cortical pathology in Alzheimer's disease (AD). Visuospatial memory paradigms that are mediated by the entorhinal-hippocampal circuit may offer a means to detect memory impairment during the early stages of AD. In this study, we developed a 4-min visuospatial memory paradigm called…
