RETAINING DONORS AND INCREASING DONATION FREQUENCY

以下提案旨在保留个人作为捐赠者 他们已进入无偿献血系统并增加 他们捐款的频率。 拟议研究的具体目标 是：（1）确定影响常规血液的显着因素 具有不同捐赠历史的个人的捐赠 - 首次、 第二次、承诺（频繁）和失效的捐赠者； (2) 开发和 评估行为模型的有效性，以提高捐赠者的保留率和 预测第一次和第二次捐赠者是否会再次捐赠； (3) 制定捐助者保留干预措施，特别是对于第一批和 第二次捐赠者； (4)首先确定同质子组， 可能接受不同类型的第二次捐赠者和坚定的捐赠者 增加捐赠频率的干预策略； (5) 评估新干预措施的成本效益成功与否 与现有血液中心维护策略相比； (6) 至 确定捐助者的捐助频率是否有限制或上限 每年都会捐款。 我们建议利用两个相关的社会 结合认知和行为方法的心理学理论 保留献血者并利用调查结果构建一个 捐助者决策的多属性模型。 行为决定 模型将用于前瞻性预测捐赠者行为并确定目标 并指导干预措施的设计，以提高捐助者的保留率和 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.
