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±5.1, 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.
