O-negative donors are a critical resource for blood collection agencies, and their recruitment and retention provides an ongoing challenge. Motivational interviewing shows promise as a tool to promote donor retention, although concerns about scalability remain. The current study examined the effect of an automated Web-based interview drawing on motivational interviewing and self-determination theory on O-negative donors' motivation, intention, and behavior.
Within 13 days of donating, 2820 O-negative donors completed baseline measures of motivation and intention before being randomly assigned to complete either a motivational interview (MI) or active control interview (ACI). Motivation and intention were assessed at 2 days and at 7 weeks after participation in the MI or ACI, with return behavior tracked for 6 months following trial completion.
Changes in donor motivation and intention, rate, and time to return did not vary by participation in the MI or ACI. When compared with O-negative donors who experienced business-as-usual practices, donors completing the MI or ACI returned to donate more, and they returned more quickly. However, subsequent exploratory analyses considering the behavior of those who did not accept the invitation to participate and those who completed only baseline measures showed that the improved return behavior of donors in the MI or ACI conditions was likely not due to any specific properties of the MI or ACI activities.
Australian O-negative donors were highly internally motivated and committed to donating. An automated Web-based motivational interview appears to be of limited effectiveness in promoting the return of such donors.
O 型阴性血献血者是血库机构的重要资源，招募和留住他们是一个持续存在的挑战。动机性访谈作为一种促进献血者保留的工具显示出了前景，但对于其可扩展性的担忧仍然存在。本研究考察了基于动机性访谈和自我决定理论的自动化网络访谈对 O 型阴性血献血者的动机、意愿和行为的影响。
在献血后 13 天内，2820 名 O 型阴性血献血者在被随机分配完成动机性访谈（MI）或主动对照访谈（ACI）之前完成了动机和意愿的基线测量。在参与 MI 或 ACI 后的 2 天和 7 周评估了动机和意愿，同时跟踪了 6 个月的随访期内的献血回归行为。
参与 MI 或 ACI 对献血者的动机和意愿变化、回归率和回归时间没有影响。与经历常规做法的 O 型阴性血献血者相比，完成 MI 或 ACI 的献血者更有可能回归并更快地回归。然而，随后的探索性分析考虑了那些未接受参与邀请和仅完成基线测量的献血者的行为，表明 MI 或 ACI 条件下献血者改善的回归行为可能不是由于 MI 或 ACI 活动的任何特定性质。
澳大利亚 O 型阴性血献血者具有高度的内在动机和承诺献血的意愿。自动化网络动机性访谈似乎对促进这类献血者的回归效果有限。
