A Comparative Validation of the Abbreviated Apathy Evaluation Scale (AES-10) With the Neuropsychiatric Inventory Apathy Subscale Against Diagnostic Criteria of Apathy

Both the AES-10 and NPIa may be used to distinguish apathetic from nonapathetic residents in a heterogeneous sample with and without dementia, or in residents without dementia. The AES-10 may be preferable to the NPIa apathy subscale when ruling out or screening for apathy. The performance of the scales against diagnostic criteria of apathy in dementia need to be further examined.
