title: [SDIALOR: a dialysis patient satisfaction questionnaire].
abstract: OBJECTIVE
  To develop and evaluate the psychometric properties of a dialysis satisfaction questionnaire in the French language.
  
  
  METHODS
  Firstly the translation and adaptation to French context in cooperation with dialysis patients and nephrologists. The satisfaction questionnaire was built using items banking, based on the Choice Satisfaction Questionnaire and Satisfaction of Patients in Chronic Dialysis (SEQUS((R))). The tool, named SDIALOR, was comprised of 41 items. Satisfaction scores are standardized from 0 (poor) to 100 (excellent). Secondly, the estimation of the questionnaire's psychometric properties. This work was realized in the Nephrolor network. The sample consisted in all of 1008 adults, prevalent patients, treated in the 12 dialysis structures of the Lorraine region on the 1st February 2004. All of them were mailed a questionnaire.
  
  
  RESULTS
  Response rate was 44.3%. Mean age of patients was 65.9 years; 67% were men and 61% retired. Mean length of dialysis was 4.5 years. Women, residents of the Meurthe and Moselle region, patients having a diabetes, having a low haemoglobin level returned the questionnaires less frequently than the other patients (p<0.05). Principal components analysis evidenced seven specific dimensions, in addition to the overall satisfaction dimension. Cronbach's alpha coefficients were greater than 0.73 for five dimensions, but "relation between nephrologist and GP" dimension (0.54). Mean scores of satisfaction varied from 53.9 ("relation between nephrologists and GP") to 74.1 ("overall satisfaction"). Older patients tended to more satisfied than the younger ones. Global satisfaction was significantly higher in peritoneal dialyses (81.7), in hemodialysis at residence (83.1) compared with that in autodialyse (70.9) and in hemodialysis at center (73.3). A significant variability from one care team to another was evidenced.
  
  
  CONCLUSIONS
  Our study proves the feasibility of satisfaction measurement at the dialyzed patient. Dialysis Patient Satisfaction Questionnaire in the French version exhibits satisfying psychometric properties. The level of satisfaction is better in peritoneal dialysis and differs according to medical care centers.
