Objective: To translate, culturally adapt, and psychometrically evaluate the Spanish version of the "Scale for End-of Life Caregiving Appraisal" (SEOLCAS).; Method: Observational cross-sectional study. Convenience sample of 201 informal end-of-life caregivers recruited in a southern Spanish hospital. The reliability of the questionnaire was assessed through its internal consistency (Cronbach's α) and temporal stability (Pearson's correlation coefficient [r] between test-retest). The content validity index of the items and the scale was calculated.
