The critical importance of including formal measures of effort in neuropsychological assessments cannot be understated. These data raise concerns about use of the RBANS embedded effort measures in dementia evaluations.ĭementia, Sub-optimal effort, RBANS, Validity indicators, Malingering, Geriatrics ES failure was low (4%) when dementia was due to Alzheimer disease (AD), but high (31%) for non-AD dementias. In contrast, failure on the ES was 14% but differed based on type of dementia. Failure rate on the EI was high (48%) and associated with dementia severity. We explored failure rates on these effort measures in a non-litigating mixed dementia sample ( N = 145).

Two embedded measures have been developed for the repeatable battery for the assessment of neuropsychological status (RBANS Randolph, C., Tierney, M. The importance of evaluating effort in neuropsychological assessments has been widely acknowledged, but measuring effort in the context of dementia remains challenging due to the impact of dementia severity on effort measure scores.
