Dementia and effort test performance
Dean AC, Victor TL, Boone KB, Philpott LM, Hess RA.. The Clinical neuropsychologist, 2008-04-08
Topic: Risk, prevention and care in population studies
Research on the performance of patients with dementia on tests of effort is particularly limited. We examined archival data from 214 non-litigating patients with dementia on 18 effort indices derived from 12 tests (WAIS-III/WAIS-R Digit Span and Vocabulary, Dot Counting Test, Warrington Recognition Memory Test-Words, WMS-III Logical Memory, Rey Word Recognition Memory Test, Finger Tapping, b-Test, Rey 15-Item, Test of Memory Malingering, Rey Auditory Verbal Learning Test, and Rey Complex Figure Test). Results indicated that recommended cut-offs for Digit Span indicators (Vocabulary Minus Digit Span and four-digit forward span time score) provided > or =90% specificity across participants, while the majority of other effort tests displayed specificities in the 30-70% range.
Key findings
- We examined archival data from 214 non-litigating patients with dementia on 18 effort indices derived from 12 tests (WAIS-III/WAIS-R Digit Span and Vocabulary, Dot Counting Test, Warrington Recognition Memory Test-Words, WMS-III Logical Memory, Rey Word Recognition Memory Test, Finger Tapping, b-Test, Rey 15-Item, Test of Memory Malingering, Rey Auditory Verbal Learning Test, and Rey Complex Figure Test).
- Results indicated that recommended cut-offs for Digit Span indicators (Vocabulary Minus Digit Span and four-digit forward span time score) provided > or =90% specificity across participants, while the majority of other effort tests displayed specificities in the 30-70% range.
- Analyses of test specificity as a function of Mini Mental Status Examination (MMSE) score and specific dementia diagnosis are provided, as well as adjustments to cut-offs to maintain specificity where feasible.
Why it matters
This study examined how people with dementia performed on tests designed to measure effort. It is about test performance and specificity of effort indices, not about treating, curing or preventing Alzheimer's disease.
