This study was designed to provide the base of nursing intervention that could help apheresis blood-donors to promote self-efficacy effectively by analyzing critical factors that influence on this. The subjects recruited for the research were 468 persons who participated in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June, 2002 using questionnaires. Data were analyzed by t-test, ANOVA, Scheffe test, and stepwise multiple regression. The results were as follows. 1. The mean self-efficacy score on the questions related to blood donation was $32.9\pm5.1$, indicating that blood donors have above the mean level of self-efficacy related to blood donation. 2. The self-efficacy score was significantly higher for the group of persons who have more than 5 times of experiences in blood donation than others who have only one experience. 3. The critical factors that influence self-efficacy related to donation were the marital status, educational level. and previous experiences of whole blood donation, while the critical factor that influence on general self-efficacy was previous experiences of whole blood donation. Therefore, it is necessary to establish more effective and organized nursing intervention strategies that can promote the self-efficacy of apheresis blood-donors.

This study was designed to provide a base for nursing intervention to help apheresis blood-donors to perform health promotion behavior effectively by surveying their health promotion behavior and by analyzing the critical factors. The study subjects were 468 participants in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June. 2002. by questionnaire. Data were analyzed by t-test, ANOVA. Scheffe test, Pearson correlation coefficient. and stepwise multiple regression. The results were as follows. 1. The degree of performance of health promotion behavior of the subjects was a total average score of $152.9\pm21.5$ points and a mean score of 2.7 points. The highest score was 'I have a good relationship with others' in the factor of self-actualization and interpersonal support. The lowest score was 'I have my blood pressure checked regularly' in the factor of health responsibility. 2. Considering the classification according to the subjects' general characteristics. the health promotion behavior score was significantly higher for soldiers than high school students, for religious believers than atheists. and for high class economic status than mid and low class economic status. Also the health promotion behavior score was higher for those who had made more than five blood donations than those who had made zero or one donation. and for those who had made more than four blood donations than for those who had made less than four blood donations in the previous times of apheresis blood donation. The score was also higher for those not having a relationship with recipient than those having a relationship. 3. The self-efficacy related to donation. general self-efficacy and self-esteem had a significant correlation with the performance in health promotion behavior. 4. The critical factors that influenced the health promotion behavior were explained by $35.6\%$ of the general self-efficacy and by $40.2\%$ of the total of self-efficacy related to donation, and previous times of apheresis blood donation. The health promotion behavior score of apheresis blood-donors differed according to job, religion, economic status, previous times of whole blood donation, previous times of apheresis blood donation, and relationship with recipient. The health promotion behavior and self-efficacy related to donation, general self-efficacy, and self-esteem showed significant positive correlation with one another. The general self-efficacy, self-efficacy related to donation, and previous times of apheresis blood donation appeared to be the significant predictive factors of health promotion behavior. Therefore, from these study results, it is necessary to establish more effective and organized nursing intervention strategies for the health promotion behavior of apheresis blood-donors.
