This study is a descriptive survey research to investicate the relation between the performance of self-care behavior and degree of self-efficacy by evaluating them respectively. The subjects were consisted of seventy nine tuberculosis patients registered in two different public health care centers in the city of Kwangju from April 1st to 30th June, 1995. The results were as follows : 1) Demorgraphically, the proportion of males was(59.5%), the highest proportion of age group was twenties with (31.6%), the highest proportion of the patients graduated high school, the married was much more than the single(51.9%). The highest proportions in each variables were as followers : middle class in economic status with 70.9%, the jobless in job status with 26.6%, the duration less than 6 months in ailing duration with 63.3%. The patients of 60.8% and 74.7% showed no family history and received no health education respectively. 2) The average degree of self-care behavior was 3.44 points (1-5 points). 3) The average degree of recognized self efficacy was 78.18 points(10-100points). 4) The recognized self efficacy showed close relationship with the performance of self-care behavior (r=0.6378, p<0.001). 5) The points of performance of self-care nursing behavior showed statistical significance in the variables of martial status, duration of treatment and economic status. (F=3.142, p<0.05) (F=3.701, p<0.05), (F=6.213, p<0.01). 6) The point of self efficacy showed statistical significance in the variables of sex, degree of education and marital status. (F=5.438, p<0.05), (F=4.28, P<0.01), (F=2.899, p<0.05) These results suggest as follows: 1) It is necessary to develop a program to improve the ability of self health care for the family member as well as the patient. 2) It is necessary to do further study on much more variables that influence on the performance of self-care behavior by expanding the number of subjects and duration of study, and to evaluate the self efficacy with time interval.
