Based on the hypothesis that self-determined motivation is associated with an increased likelihood of future behavior, the present study examined the ability of a motivational interview to promote internal motivation for giving blood and future donation attempts.
A sample of 484 recent whole-blood and double red blood cell donors (62.4% female; age = 30.2 ± 11.8 years) were randomly assigned to either a telephone-delivered motivational interview or a control call approximately 6 weeks after donating. Several weeks before the call and again 1 week after the call, participants completed the Blood Donor Identity Survey, a multidimensional measure of donor motivation, to derive indices of amotivation, external motivation, and internal motivation to give blood. Repeat donation attempts were tracked using blood center records.
Relative to controls, participants in the motivational interview group showed a shift toward more self-determined motivation, as indicated by significant decreases in amotivation (p = 0.01) and significant increases in external (p = 0.009) and internal (p = 0.002) motivation. Furthermore, those with initially high levels of autonomous motivation were more likely to make a donation attempt in the subsequent year if they completed the motivational interview (71.1%) versus the control call (55.1%).
Motivational interviewing is a potentially useful strategy to enhance retention of existing blood donors, particularly among those who express a greater sense of internal motivation for giving.
基于自我决定动机与未来行为可能性增加相关的假设，本研究考察了动机性访谈促进献血内在动机和未来献血尝试的能力。
484名近期的全血和双份红细胞献血者样本（62.4%为女性；年龄 = 30.2 ± 11.8岁）在献血后约6周被随机分配接受电话动机性访谈或对照通话。在通话前几周和通话后1周，参与者完成了献血者身份调查，这是一种对献血者动机的多维度测量，以得出无动机、外部动机和献血内在动机的指标。使用血库记录追踪重复献血尝试情况。
与对照组相比，动机性访谈组的参与者表现出向更多自我决定动机的转变，表现为无动机显著降低（p = 0.01），外部动机（p = 0.009）和内部动机（p = 0.002）显著增加。此外，那些最初具有较高自主动机水平的人，如果完成动机性访谈，在随后一年进行献血尝试的可能性更大（71.1%），而接受对照通话的比例为（55.1%）。
动机性访谈是提高现有献血者留存率的一种潜在有用策略，特别是在那些表现出更强献血内在动机的人中。
