Inter-rating reliability of the Swiss easy-read integrated palliative care outcome scale for people with dementia.

Limited research has been conducted on the measurement error and reliability of patient-centred outcome measures for people with dementia who are living in nursing homes. The Swiss Easy-Read IPOS-Dem is a promising instrument but requires further improvement to be reliable for research or decision making. Future studies may look at its measurement properties for different rater populations or at different stages of dementia. Furthermore, there is a need to establish the construct validity and internal consistency of the easy-read IPOS-Dem.
