Psychometric Analysis of an Advance Care Planning Implementation Quality Assessment Tool (ACP-QAT) for Nursing Homes

A reliable and valid assessment of advance care planning (ACP) implementation in nursing homes (NHs) remains a gap, which can be a hindrance for policymakers and researchers to holistically understand the current quality of ACP implementation and identify aspects for improvement. This paper therefore conducted a psychometric analysis of the Advance Care Planning Implementation Quality Assessment Tool (ACP-QAT) to examine its internal consistency reliability, interrater reliability, and construct validity, including convergent validity and known-group validity.
