Chronic renal failure patients have many stresses that were related to disease itself and maintenance hemodialysis treatment. And their adaptation to disease related stress has been failed. For the purposes of this study are;
1. to develop instruments that can be used for measuring stress and adaptation of chronic renal failure patients,
2. to analyze the hypothesized causal model on the pathway between chronic renal failure patients´ stress and adaptation.
The data for this study were collected by nonstructured face-to-face interviewing of 21 chronic renal failure patients for development of stress and adaptation scales, and by using questionnaire and interviewing of 207 patients for analysis on the pathway between chronic renal failure patients´ stress and adaptation.
The instruments used for this study were Stress scale, Coping scale, Psychosocial adjustment scale, Self-esteem scale and Perceived family support scale. Stress and Coping scale were developed by researcher base on nonstructured interview with chronic renal failure patients and Psychosocial adjustment scale was developed base on PAIS.
All instruments were found to have reasonable validity and reliability.
The collected data were analyzed by using descriptive qualitative method for Stress and Coping scale development and by using S.A.S. program for analysis on the pathway between stress and adaptation.
For analysis hypothesized causal model on the pathway between chronic renal failure patients´ stress and adaptation, path analysis was used.
In additional analysis, for measuring the differences in degree of adaptation as related to personal characteristics were done using by ANOVA.
The reliability of the instruments were tested by Cronbach´s alpha coeficient and the relationship between coping and psychoscial adjustment scale was analyzed by Pearson correlation. The results are summarized as follows:
1. Chronic renal failure patients´ 42 items of Stress scale and 32 items of Coping scale are composed of base on nonstructured face-to-face interview with the patients, and Psychosocial adjunstment scale is composed of 46 items base on PAIS, and the Cronbach´s alpha coefficients of Stress, Coping and Psychosocial ad justmetn scale were .92, .70, and .87, and the mean score of stress, coping and Psychosocial adjustment were 3.18(total 5),3.50(total 5),and 3.09(total 5).
2. In analysis on the pathway between chronic renal failure patients´ stress and adaptation, there are significant (P <.000 1 ) causal relations between adaptation and stress, perceived family support as well. as self-esteem (,6= -.6936,.3051,.2499), and self-esteem between stress as well as perceived family support( R=-.5029,.1601), and stress between perceived family support (fl=-.3065).
