title: Psychosocial predictors of the quality of life of chronic renal failure patients undergoing haemodialysis.
abstract: OBJECTIVE
  To assess health-related quality of life (HRQOL) of chronic renal failure patients undergoing dialysis replacement therapy, and to evaluate the predictive power of psychosocial variables (social support, self-efficacy, optimistic outlook, depression, anxiety and coping strategies) on the different levels of HRQOL.
  
  
  METHODS
  We evaluated the HRQOL of 39 haemodialysis patients using the SF-36 instrument. The predictive ability of the evaluated variables was analysed using bivariate correlations and multiple regression analysis.
  
  
  RESULTS
  Patients showed lower levels of HRQOL than the reference values for the instrument. Depression is the main predictor of HRQOL, associated negatively with all of its components. The degree of concern and the use of passive coping strategies for stress such as helplessness-hopelessness, and fatalism are also associated with lower levels of HRQOL. By contrast, self-efficacy, optimism, social support, and fighting spirit were associated with higher levels of HRQOL.
  
  
  CONCLUSIONS
  These results have clear clinical implications regarding the ways in which psychological interventions should be aimed at improving HRQOL in renal patients.
