The purpose of the study was to investigate factors related to management behavior and self-efficacy of hemodialysis(HD) patient. The study was done with 88 outpatients on HD. The patients answered self-administered questionnaires based on the following scale: management behaviors of fluid-intake and self-medication, perceived self-efficacy of those behaviors, self-care support by family, self-determination of the management behaviors, sense of fulfillment in life, mental and somatic symptoms and knowledge about HD. Better management behaviors were counted as higher scores. (1)Path analysis showed that the factors with direct positive effects on management behaviors of fluid-intake and self-medication were perceived self-efficacy of the management behaviors, self-care support by family and female gender. However knowledge about HD had a direct negative effect. (2)The factors with direct positive effects on self-efficacy of the managecment behaviors were self-care support by family and self-determination of the behaviors. These results suggest that psychosociological factors have impodant influence on management behaviors and self-efficacy in HD patients.
