However, the distinction between these two concepts has not been studied in family caregivers. Objective: To examine whether these two concepts are distinct by comparing their evolution and predictors over cancer patients' last year. Methods: Agreement between emotional preparedness for death and cognitive PA was longitudinally evaluated for 309 family caregivers by percentages and kappa coefficients.
