Psychosocial predictors of the quality of life of chronic renal failure patients undergoing haemodialysis.

Objectives: 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.
