With an ever-increasing demand on blood supplies worldwide, there is an immense need to ensure a safe and sufficient supply of blood products. However, recruiting and retaining blood donors remain key challenges for blood agencies. In an attempt to address these problems, researchers have identified a range of sociodemographic, organizational, physiological, and psychological factors that influence people's willingness to donate blood. Although past research has largely focused on donor recruitment, in particular, demographic variables associated with blood donation behavior, the issue of donor retention has become increasingly important. A growing number of studies have also highlighted the role of psychological factors in explaining, predicting, and promoting blood donation behavior. In line with recent trends in blood donation research, the present article reviews the contributions of, and current directions in, psychological research on blood donation attitudes and behavior, with special emphasis on donor return and repeat blood donation behavior. Although there is overlap between factors that predict the initiation and the maintenance of blood donation behavior, it is suggested that changes in motivation and the development of self-identity as a blood donor are crucial for understanding the processes whereby first-time donors become repeat donors.

献血心理学：当前的研究和未来的方向。

随着全球对血液供应的需求不断增长，迫切需要确保安全和充足的血液供应。然而，招募和保留献血者仍然是血液机构的主要挑战。为了解决这些问题，研究人员确定了一系列社会人口统计学，组织，生理和心理因素，这些因素会影响人们的献血意愿。尽管过去的研究主要集中在献血者的募集上，特别是与献血行为有关的人口统计学变量，但献血者保留的问题变得越来越重要。越来越多的研究也强调了心理因素在解释，预测和促进献血行为中的作用。与献血研究的最新趋势一致，本文回顾了有关献血态度和行为的心理学研究的贡献和当前的方向，特别着重于献血者的返还和重复献血行为。尽管在预测献血行为的开始和维持的因素之间存在重叠，但建议动机的变化和作为献血者的自我认同的发展对于理解首次献血者成为重复献血者的过程至关重要。 。
