Background: There is a need for instruments that can evaluate the psychosocial quality of dying in nursing homes. The aim of this study was to adapt and validate the Quality of Dying in Long-Term Care scale (QoD-LTC) to the Spanish context. Methods: Descriptive cross-sectional study. Fourteen nurses from 7 facilities in southern Spain assessed 153 residents who died in the centers; validity, reliability, and feasibility were evaluated. Results: The Spanish version consists of 11 items with acceptable reliability (α = 0.681). Three factors model was validated by principal components analysis. A mean of 180.62 (SD = 86.66) seconds is needed to fill it in. An inter-observer 0.753 (95% CI: 0.391–0.900, p<0.001) and intra-observer 0.855 (95% CI: 0.568–0.951 p = 0.001) reliability were observed. Weak correlation was observed; positive with mono-item question (0.322) and negative with Eastern Cooperative Oncology Group (ECOG) with a value of (−0.321) and Integrated Palliative outcome scale (IPOS) with a value of (−0.252). Conclusions: The QoD-LTC scale presents an adequate factorial structure, internal consistency, and feasibility to evaluate psychosocial quality of dying in nursing homes. It can be used as a quality indicator. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
