OBJECTIVE: The aim of this study was to evaluate the self care agency and self efficiency levels of the hemodialysis and continuous ambulatory peritoneal dialysis (CAPD) patients, and to define the factors effecting self care and self efficiency. MATERIAL and METHODS: This cross sectional study was carried out on 143 patients who were admitted to the Erciyes University Faculty of Medicine hospital for dialysis between August-December 2016. The Self-Care Agency Scale, General Self Efficiency Scale, demographic and socio-cultural properties of the patients, and a questionnaire including information about the disease were used for collecting data. RESULTS: The mean value of the self-care agency scores in men was statistically significantly higher than in women (106.2±16.6 vs. 99.9±20.1).The mean value of the general self efficiency scores in university graduates was statistically significantly higher than in elementary school graduates (70.4±9.5 vs. 60.7±14.2). The mean value of the self-care agency scores in housewives was statistically significantly lower than in the other occupation groups (99.0±20.9). The mean score of general self efficiency scores in people living in slums was lower than in the other groups (53.6±14.2). CONCLUSION: In hemodialysis and CAPD patients, it has been found that the general efficiency level increases as self care agency increases.
