Method: Two-hundred and thirty
dyads of PWDs and their family carers were included. The
PWDs were assessed with the Neuropsychiatric Inventory
(NPI-Q), two Activities of Daily Living (ADL) scales, the Cornell
Scale and the QoL-Alzheimer’s Disease scale (QoL-AD; selfand
proxy-reported scores). The carers were assessed with
the QoL-AD and the Geriatric Depression Scale.
