title: Cross-cultural adaptation to Portuguese of tools for assessing the nutritional status of patients on dialysis.
abstract: BACKGROUND
  The 7 point subjective global assessment (7p-SGA) and the malnutrition inflammation score (MIS) are tools commonly applied for the assessment of nutritional status in dialyzed patients. Both were developed in English and require translation to Portuguese to be applied in Brazil. The cross-cultural equivalence process ensures semantic and measurement equivalence of a translated tool.
  
  
  OBJECTIVE
  To perform the cross-cultural adaptation to Portuguese of the 7p-SGA and MIS.
  
  
  METHODS
  Semantic equivalence was performed by the back-translation method and by assessing the degree of similarity between the original instrument and that back-translated from Portuguese to English (Back-translation). The assessment of the equivalence measurement was made by evaluating the intern reliability (Cronbach's α) and interobserver reliability (two observers). One-hundred and one elderly patients on hemodialysis (HD) were included.
  
  
  RESULTS
  Both instruments showed a high degree of semantic similarity with results close to the maximum value (7p-SGA 96.8 ± 7.8 and MIS 99.6 ± 1.4). The intern consistency showed a Cronbach's α value for 7p-SGA of 0.72 and of 0.53 for MIS. The interobserver reproducibility of 7p-SGA was moderate (intraclass coefficient [ICC] = 0.74 [95% CI: 0.58; 0.84]), while for MIS was strong (ICC = 0.88 [95% CI: 0.81; 0.93]).
  
  
  CONCLUSIONS
  The 7p-SGA and MIS translated into Portuguese can be applied for assessing the nutritional status of elderly patients on HD. Studies testing the applicability of these instruments in adult patients on HD and in peritoneal dialysis should yet be performed.
