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<.001)
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±6.93 mean mark 3.28±0.43 and the mea score of self-efficacy was 45.44±7.75 mean mark 2.87±0.49 and the mea score of quality of life was 121.27±23.81 mean mark 2.96±0.58.
2. There were significant differences in the level of powerlessness according to sex(t=2.148, p=.033), occupation (t=3.682, p=.000.) economic status(F=3.094, p=.048) experience of hospitalization (t=-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) rligion (F=2.667 p=.048) hemodialysis period(F=2.991, p=.032) hemodialysis frequency (t=9.045 p=.003) experience fo hospitalization (t=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).
