首次献血者对美国献血者群体至关重要，他们提供了所有献血的近三分之一。不幸的是，重复捐赠有各种各样的障碍，新的捐赠者很难留住。由于每个捐赠者都经历了一系列独特的阻碍因素，我们根据激励性访谈原则开发了一个捐赠后访谈，以灵活地解决个人障碍。这项随机临床试验的主要目的是检查首次O组献血者的保留情况，这些献血者被随机分配接受电话采访，其中包括动机和行动计划组件，或者在献血后约六周接受标准护理控制电话。在电话联系之前和之后，使用在线调查测量献血态度、感知行为控制、意图和动机自主性，并使用血液中心献血者数据库跟踪献血尝试一年。我们假设，与对照组相比，接受电话采访的捐赠者更有可能在接下来的一年中尝试捐赠。此外，我们将使用自我决定理论（即，动机自主）和计划行为理论（即，态度、感知行为控制和意图）。这种干预的结果可能有助于支持一种新的战略，以提高保留选定的献血者，以更好地满足国家的血液供应需求。
First-time blood donors are essential to the US donor pool, providing nearly a third of all donations. Unfortunately, there are a wide variety of obstacles to repeat donation and new donors are extremely difficult to retain. Because each donor experiences a unique set of deterrents, we developed a post-donation interview based on motivational interview principles in order to flexibly address individual barriers. The primary aim of this randomized clinical trial is to examine retention of first-time, group O blood donors who are randomly assigned to receive either a telephone-delivered interview with motivational and action planning components or a standard-of-care control call approximately six weeks after their donation. Measures of donation attitude, perceived behavioral control, intention, and motivational autonomy will be measured before and after the telephone contact using online surveys, and donation attempts will be tracked for one year using blood center donor databases. We hypothesize that, compared to controls, donors who receive the telephone interview will be more likely to make a donation attempt over the following year. In addition, we will examine possible mechanisms of action of the interview using key predictors of donation behavior as described by Self Determination Theory (i.e., motivational autonomy) and the Theory of Planned Behavior (i.e., attitude, perceived behavioral control, and intention). Results of this intervention may help to support a novel strategy to enhance retention of selected blood donors in an effort to better meet the nation’s blood supply needs.
