Sleep-related measurements to assess sleep disturbances among people living with dementia in nursing homes: a systematic review.

No measurement without adaptation can be recommended for PLWD in nursing homes. If existing measurements are used in clinical practice, the self-perspective of PLWD should be taken into account. If this is no longer fully possible, proxy-rating perspectives in combination could be an option. Future research on sleep-related measurements should be strictly based on international consensus-based psychometric quality criteria.
