The purpose of this study was to explore the relationship between optimism and life satisfaction among patients with end-stage renal disease who decide to wait or not to wait for kidney transplantation. This cross-sectional, correlation design study was performed from July 2007 to June 2008. Subjects were recruited by purposive sampling in the clinics of kidney transplantation, renal disease, hemodialysis, and peritoneal dialysis. Three hundred fifty questionnaires were distributed, we analyzed the 335 returned including 196 subjects in the waiting group and 139 in the non-waiting group. Parameters included patient basic information, optimism, and life satisfaction scales. Data were analyzed by independent t-student's, chi-square, Pearson correlation, and stepwise multiple regression tests. The subjects in both the waiting and non-waiting groups reported moderate levels of life satisfaction; whereas, the latter reported a greater life satisfaction in general. All participants had good optimism that was positively related to their life satisfaction. Other factors of optimism, age, work ability, waiting transplantation or not, and marriage status were also significantly associated with life satisfaction.
