Comparison of the repeatable battery for the assessment of neuropsychological status effort scale and effort index in a dementia sample.

The aim of the current study was to compare two embedded measures of effort for the repeatable battery for the assessment of neuropsychological status (RBANS). Sensitivity and specificity of the Effort Index (EI) and Effort Scale (ES) were compared in a sample of individuals with genuine memory impairment (MI) and individuals coached to simulate MI. Overall, the EI yielded a sensitivity of 0.
