This study was part of a larger project that aims to develop learning strategies to transfer scientific knowledge regarding person-centered care (PCC) into tools and instruments for healthcare professionals who work in daily practice in nursing homes (NHs). As part of the learning strategies, we aimed to develop a tool that enables healthcare professionals to evaluate and improve their own PCC. The research question was: Which tool provides healthcare professionals in NHs insight into the extent to which they provide PCC so that they can learn and improve in PCC without additional care registrations?
