Validation of one-year reliable change in the RBANS for community-dwelling older adults with amnestic mild cognitive impairment.

Dustin B Hammers, Kayla R Suhrie, Sariah M Porter, Ava M Dixon, Kevin Duff,

OBJECTIVE:The current study sought to externally validate previously published standardized regression-based (SRB) equations for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Indexes administered twice over a one-year period. Method: Hammers and colleagues' SRB prediction equations were applied to two independent samples of community-dwelling older adults with amnestic ... Read more >>

Validating 1-Year Reliable Change Methods.

Dustin B Hammers, Sariah Porter, Ava Dixon, Kayla R Suhrie, Kevin Duff,

OBJECTIVE:reliable change methods can assist in the determination of whether observed changes in performance are meaningful. The current study sought to validate previously published 1-year standardized regression-based (SRB) equations for commonly administered neuropsychological measures that incorporated baseline performances, demographics, and 1-week practice effects. METHOD:Duff et al.'s SRB prediction equations were applied ... Read more >>

Recognition subtests for the Repeatable Battery for the Assessment of Neuropsychological Status: Preliminary data in cognitively intact older adults, amnestic Mild Cognitive Impairment, and Alzheimer's disease.

Kevin Duff, Kayla R Suhrie, Bonnie C A Dalley, Sariah M Porter, Ava M Dixon,

OBJECTIVE:The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) has three delayed recall subtests (list, story, figure), but only one delayed recognition subtest (list). Since comparisons between delayed recall and recognition can be useful in clinical neuropsychology, the current study sought to develop and preliminarily examine two proposed new ... Read more >>

Validation of one-week reliable change methods in cognitively intact community-dwelling older adults.

Dustin B Hammers, Kayla R Suhrie, Ava Dixon, Sariah Porter, Kevin Duff,

OBJECTIVE:Reliable change methods can assist the determination of whether observed changes in performance are meaningful. The current study sought to validate previously published standardized regression-based (SRB) equations for commonly administered cognitive tests using a cognitively intact sample of older adults, and extend findings by including relevant demographic and test-related variables ...

Generalizability of reliable change equations for the RBANS over one year in community-dwelling older adults.

Dustin B Hammers, Kayla R Suhrie, Sariah M Porter, Ava M Dixon, Kevin Duff,

Objective: Reliable change methods can assist neuropsychologists in determining whether observed changes in a patient's performance are clinically meaningful. The current study sought to validate previously published standardized regression-based (SRB) equations for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Indexes and subtests.Methods: Duff and colleagues's SRB prediction ...

Reliable change in cognition over 1 week in community-dwelling older adults: a validation and extension study.

Dustin B Hammers, Kayla R Suhrie, Ava Dixon, Sariah Porter, Kevin Duff,

OBJECTIVE:Reliable change methods can aid neuropsychologists in understanding if performance differences over time represent clinically meaningful change or reflect benefit from practice. The current study sought to externally validate the previously published standardized regression-based (SRB) prediction equations developed by Duff for commonly administered cognitive measures. METHOD:This study applied Duff's SRB ... Read more >>

Predicting Premorbid Scores on the Repeatable Battery for the Assessment of Neuropsychological Status and their Validation in an Elderly Sample.

Kevin Duff, Bonnie C A Dalley, Kayla R Suhrie, Dustin B Hammers,

OBJECTIVE:Assessing cognitive change during a single visit requires the comparison of estimated premorbid abilities and current neuropsychological functioning. Although premorbid intellect has been widely examined, premorbid expectations for other cognitive abilities have received less attention. The current study sought to develop and validate premorbid estimates for the Repeatable Battery for ... Read more >>

Short-term repeat cognitive testing and its relationship to hippocampal volumes in older adults.

Kevin Duff, Jeffrey S Anderson, Atul K Mallik, Kayla R Suhrie, Taylor J Atkinson, Bonnie C A Dalley, Sarah Shizuko Morimoto, John M Hoffman,

BACKGROUND:Practice effects are improvements in cognitive test scores due to repeated exposure to testing materials. If practice effects provide information about Alzheimer's disease pathology, then they could be useful for clinical trials enrichment. The current study sought to add to the limited literature on short-term practice effects on cognitive tests ... Read more >>

External validation of change formulae in neuropsychology with neuroimaging biomarkers: A methodological recommendation and preliminary clinical data.

Kevin Duff, Kayla R Suhrie, Bonnie C A Dalley, Jeffrey S Anderson, John M Hoffman,

OBJECTIVE:Within neuropsychology, a number of mathematical formulae (e.g. reliable change index, standardized regression based) have been used to determine if change across time has reliably occurred. When these formulae have been compared, they often produce different results, but 'different' results do not necessarily indicate which formulae are 'best.' The current ... Read more >>

Amyloid Positivity Using [18F]Flutemetamol-PET and Cognitive Deficits in Nondemented Community-Dwelling Older Adults.

Dustin B Hammers, Taylor J Atkinson, Bonnie C A Dalley, Kayla R Suhrie, Kevin P Horn, Kelli M Rasmussen, Britney E Beardmore, Lance D Burrell, Kevin Duff, John M Hoffman,

Little research exists examining the relationship between beta-amyloid neuritic plaque density via [18F]flutemetamol binding and cognition; consequently, the purpose of the current study was to compare cognitive performances among individuals having either increased amyloid deposition (Flute+) or minimal amyloid deposition (Flute-). Twenty-seven nondemented community-dwelling adults over the age of 65 ... Read more >>

Relationship between 18F-Flutemetamol uptake and RBANS performance in non-demented community-dwelling older adults.

Dustin B Hammers, Taylor J Atkinson, Bonnie C A Dalley, Kayla R Suhrie, Britney E Beardmore, Lance D Burrell, Kevin P Horn, Kelli M Rasmussen, Norman L Foster, Kevin Duff, John M Hoffman,

OBJECTIVE:The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) has been used extensively for clinical care and in research for patients with mild cognitive impairment and Alzheimer's disease (AD); however, relatively few studies have evaluated the relationship between RBANS performance and AD imaging biomarkers. The purpose of the current ... Read more >>

Short-term practice effects in mild cognitive impairment: Evaluating different methods of change.

Kevin Duff, Taylor J Atkinson, Kayla R Suhrie, Bonnie C Allred Dalley, Sydney Y Schaefer, Dustin B Hammers,

Practice effects are improvements on cognitive tests as a result of repeated exposure to testing material. However, variability exists in the literature about whether patients with amnestic mild cognitive impairment (MCI) display practice effects, which may be partially due to the methods used to calculate these changes on repeated tests. ...
