Tradução, adaptação cultural e validação do Kidney Disease Loss Scale para o contexto brasileiro
Abstract
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.
