An effort index for the repeatable battery for the assessment of neuropsychological status (rbans)

The present study aimed to dei,elop an internal vafidi j, indicator for a brief general purpose screening battery, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Two subtests of the RBANS were predicted to be relath,ely resilient to cognitive dy function on the basis of previous research. An Effort Index (EI) was created by combining them via a scaling system. The frequency of EI scores was first examined in a heterogenous clinical sample. A subsequent validation study showed good discriminability. In conclusion, the EI appears to he useful for detecting insufficient effort oil a screening battery.
