Relationship among Powerlessness. Self-Efficacy and Quality of Life in Hemodialysis Patients / 재활간호학회지

ABSTRACT

The purpose of this study was to the relationship between powerlessness, self-efficacy and quality of life in hemodialysis patients. The subjects were compromised of 198 hemodialysis patients from Pusan, Kyung-Sang Namdo and Kyung-Sang Bukdo 6 hemodialysis clinics. There were significant positive correlation between self-efficacy and quality of life(r= .512, p .00l). Data were collected by questionnaires from Sep. 19 to Oct. 27, 2001. The instrument used for study were the Powerlessness Behavioral Assessment Tool (Miller, 1983) and self-efficacy developed by Kim, Ju-Hyun(1995) and quality of life developed by Kim, Ok-Soo(1993). Collected data were analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheffe test, pearson correlation The results were as follows. 1. The mean score of powerlessness was 52.41+/-.93, mean mark 3.28+/-.43, and the mea score of self-efficacy was 45.44+/-.75, mean mark 2.87+/-.49, and the mea score of quality of life was 121.27+/-3.81. mean mark 2.96+/-.58. 2. There were significant differences in the level of powerlessness according to sex (1,=2.148, p= .033), occupation(t=3.682, p=.000), economic status(F=3.094, p=.048), experience of hospitalization (1,=-2.002. p= .047). 3. There were significant differences in the level of self-efficacy according to age(F=3.271. p=.013), economic status (F=5.759, p=.004), religion(F=2.667, p= .048), hemodialysis period(F=2.991. p =.032), hemodialysis frequency(t = 9.045, p = .003), experience of hospitalization (1,=4.40, p=.037). 4. There were significant differences in the level of quality of life according to occupation(t=3.796, p=.053), economic status(F=11.478, p=.000), hemodialysis frequency(t=7.573, p=.006). 5 There were significant negative correlation between powerlessness and self-efficacy (r=- .401. p .001), powerlessness and quality of .life(r=- .562, p .001),
