Donation barriers are a crucial factor to consider in the study of blood donor behavior. Since blood donors do not behave homogeneously, the aim of this work is to analyze how the donor profile (i.e. sociodemographic characteristics and donation behavior) influences the prevalence of blood donation barriers. A total of 5,353 active donors in the Canary Islands (Spain) completed an online survey. Given the general lack of agreement concerning the conceptualization and measurement of donation barriers, an integrative 25-item barrier scale, which is the result of grouping all barriers identified in the literature according to the concept of obstacle which they represent, was designed and validated. The results indicate that individuals between 18 and 35 years of age, with university education and higher income are more likely to be affected by donation barriers. At the same time, individuals who donate once or twice a year, and those with shorter experience as donors, are more prone to experience donation barriers. The present study is useful for blood transfusion centers, because it shows that centers must identify which donation barriers are the most prevalent in their donor pool, as well as which donor groups are the most affected by them. Thus, blood transfusion centers will be able to design appropriate marketing actions to reduce or eliminate those barriers that prevent active donors to donate repetively.

献血障碍是研究献血者行为时需要考虑的关键因素。由于献血者的行为不同，这项工作的目的是分析献血者概况（即社会人口学特征和献血行为）如何影响献血障碍的普遍性。加那利群岛（西班牙）共有 5,353 名活跃捐助者完成了在线调查。鉴于在捐赠障碍的概念化和测量方面普遍缺乏共识，设计并验证了一个综合的 25 项障碍量表，这是根据文献中确定的障碍所代表的概念对所有障碍进行分组的结果。结果表明，年龄在 18 至 35 岁之间的人，受过大学教育且收入较高的人更容易受到捐赠障碍的影响。同时，每年捐赠一两次的个人，以及捐赠经验较短的人，更容易遇到捐赠障碍。本研究对输血中心很有用，因为它表明中心必须确定哪些捐献障碍在其捐献者库中最为普遍，以及哪些捐献者群体受其影响最大。因此，输血中心将能够设计适当的营销行动，以减少或消除那些阻止积极献血者重复献血的障碍。本研究对输血中心很有用，因为它表明中心必须确定哪些捐献障碍在其捐献者库中最为普遍，以及哪些捐献者群体受其影响最大。因此，输血中心将能够设计适当的营销行动，以减少或消除那些阻止积极献血者重复献血的障碍。本研究对输血中心很有用，因为它表明中心必须确定哪些捐献障碍在其捐献者库中最为普遍，以及哪些捐献者群体受其影响最大。因此，输血中心将能够设计适当的营销行动，以减少或消除那些阻止积极献血者重复献血的障碍。
