This study is a discriptive research to identify stress and powerlessness based on Korean hemodialysis patients' constitution. Research subject was 112 hemodialysis patients who are treatment processing in P university hospital and K hemodialysis hospital in S City, and the data were collected for 60 days from December 20, 1999 to January 30, 2000. The research tools used for the measurement of constitution was "QSCC II", the measurement of the stress was Jeon chi ja's "Scale of Hemodialysis patient's Stress"(1985), and the measurement of powerlessness was Kim joe ja's "Scale of Powerlessness"(1992). The reliability of the scale for stress is Cronbach's Alpha 0.8819 and that of powerlessness is Cronbach's Alpha 0.6993. Data analysis was performed using SPSSWin 9.0 software. We tested them with real number, percentage, average score, standard deviation, t-test, F-test(ANOVA), Pearson's Correlation Coefficient, and Multiple stepwise regression. The results of this study were as follows : 1. Hemodialysis patients' constitution were : Soyangin 38.4%, Taemin 34.8%, and Soeumin 26.8%. 2. The average score of the stress by hemodialysis patients were the mean $89.72{\pm}20.26$ points. The average score of powerlessness was the mean $34.19{\pm}6.46$ points, by hemodialysis patients. 3. The result of the Pearson Correlation showed no correlation between the score of stress and the score of powerlessness. 4. In their relationship between general characteristics and the score of stress : in marriage state, job(P=0.016, P=0.007) and In their relationship between general characteristics and the score of powerlessness : in age, marriage state, educational level, job(P=0.000, P=0.012, P=0.002, P=0.050) have statistically meaningful differences. 5. The factor affecting the powerlessness of hemodialysis patients was physical area of stress and its explanatory power was 18.5%.
