RETAINING DONORS AND INCREASING DONATION FREQUENCY

以下提案旨在保留个人作为捐赠者一次 他们已经进入了自愿献血系统，并增加了 他们的捐赠频率。拟议研究的具体目标 主要有：(1)找出影响常规血液的重要因素 有不同捐赠历史的个人的捐赠-第一次， 第二次、承诺(经常)和失效的捐赠者；(2)发展和 评估行为模型的有效性，以增加供者保留率和 预测首次和第二次捐赠者是否会再次捐款；(3) 制定保留捐献者的干预措施，特别是针对第一次和 第二次捐赠者；以及(4)在第一次捐赠者中识别同质亚群， 第二个和承诺的捐赠者，可能会接受不同类型的 采取干预策略，增加其捐款频率；(5) 评估新干预措施的成本效益成功 与现有的血液中心维护策略相比；以及(6) 确定捐赠者是否对其频率有限制或上限 将每年捐赠一次。我们建议借鉴两个相关的社会 将认知和行为方法结合起来的心理学理论 并利用这一发现构建一种 捐赠者决策的多属性模型。行为上的决定 模型将用于预测捐赠者行为的前瞻性和针对性 并指导干预措施的设计，以增加捐赠者的留存和 捐款的频率。

The following proposal is designed to retain individuals as donors once they have entered the voluntary blood donation system and to increase the frequency of their donations. The specific aims of the proposed study are: (1) to identify significant factors influencing regular blood donations by individuals with different donation histories - first-time, second-time, committed (frequent), and lapsed donors; (2) to develop and assess the validity of behavioral models to increase donor retention and to predict whether first and second time donors will contribute again; (3) to develop donor-retention interventions, especially for the first and second time donors; and (4) to identify homogeneous subgroups among first, second and committed donors who may be receptive to different types of intervention strategies to increase the frequency of their donations; (5) to evaluate the success of cost-effectiveness of the new interventions compared to existing blood center maintenance strategies; and (6) to identify whether or not donors have a limit or ceiling on how often they will donate per year. We propose to draw on two related social psychological theories to combine cognitive and behavioral approaches to blood donor retention and to use the findings to construct a multiattribute model of donor decision-making. A behavioral decision model will be used to predict donor behavior prospectively and to target and direct the design of interventions to increase donor retention and the frequency of donations.
