Losses can be conceptualized as cognitive and affective responses to individual sorrows, characterized by brooding, yearning, disbelief and stunned feelings, being clinically significant in chronic diseases. This study aimed to translate, adapt and validate the Kidney Disease Loss Scale for the Brazilian context. This is a methodological study in which they followed the steps recommended in the literature for healthcare instruments which are: initial translation, synthesis of translations, back translation, review by a especilistas committee, pre-testing and evaluation of psychometric properties instrument. All ethical guidelines were followed. The previous steps were performed in the pre-test losses Scale related to kidney disease was an instrument easy to understand and apply. Regarding the evaluation stage of the psychometric properties of the scale of losses relating to kidney disease, verifcou to reliability and reproducibility through Cronbach's alpha and intraclass correlation index, respectively, which showed satisfactory values. Furthermore, it was verified concurrent and convergent validity through the Pearson correlation coefficient, which indicated a positive correlation between the loss and the levels of anxiety and depression and negative correlation between losses and domains of quality of life, with statistical significance using. The discriminant validity was analyzed by comparing the average loss between the groups with and without depression symptoms, with and without anxiety and with better quality or lower quality of life, which in the vast majority were statistically significant. Also held factorial analysis, which indicated the solution of a factor, being satisfactory for this set of items. This solution produced a factor with eigenvalue 3.58 and explained 59.7% of the total variance. Based on the proposed objectives and results, it is concluded that the loss has been translated, adapted and validated for the Brazilian context, allowing future studies of losses and providing tools for the professionals working in dialysis centers for assistance to people with chronic kidney disease dialysis.
