Abstract

Objectives

This study aimed to measure the psychometrics qualities of an extended model of the Theory of Planned Behavior (TPB) applied to plasma donation, and its relevance in the evaluation of interventions aiming at converting whole-blood donors (WBD) to plasma donation.

Methods

Two studies were conducted. The first (N = 433) compared the efficacy of two communication strategies (standard strategy centered on motivations to donate vs. experimental strategy centered on barriers to donate) for influencing specific determinants of the extended model of the TPB and for engaging WBD in plasma donation. The second study (N = 309) evaluated the gain of adding to the experimental strategy an implementation intentions protocol to facilitate the behavior.

Results

Study 1 showed the relevance of the extended model as a measurement tool of intention’s determinants, and the efficacy of the experimental strategy compared to the standard approach to bolster intention, F(2,430) = 7.03, p < 0.001, partial η² = 0.032, and to increase the likelihood of commitments χ2(2, N = 433) = 11.904, p = 0.003, Cramer’s V = 0.17. Study 2 replicated these results but did not demonstrate any effect of the implementation intentions protocol to strengthen the intervention, χ²(1, N = 188) = 1.341, p = 0.25.

Conclusions

These studies showed that addressing barriers to donation is an efficient communication and recruitment strategy. We encourage blood collection agencies to develop communication campaigns in this direction rather than focusing on donors motivations.

减少参与血浆置换捐献的阻碍：实验性传单的评估。

目的：本研究旨在测量计划行为理论（TPB）应用于血浆捐献的扩展模型的心理测量学质量，及其在旨在将全血献血者（WBD）转化为血浆捐献的干预措施评估中的相关性。方法：进行两项研究。第一项研究（N= 433）比较了两种沟通策略（以捐赠动机为中心的标准策略与以捐赠障碍为中心的实验策略）在影响TPB扩展模型的特定决定因素和让WBD参与血浆捐赠方面的效果。第二项研究（N= 309）评估了在实验策略中加入实施意图协议以促进行为的收益。结果：研究1显示了扩展模型作为意向决定因素的测量工具的相关性，与标准方法相比，实验策略在增强意向方面的有效性，F(2,430)= 7.03, p< 0.001，偏η2= 0.032，并增加承诺可能性χ2(2， N= 433)= 11.904, p= 0.003, Cramer's V= 0.17。研究2重复了这些结果，但没有证明实施意图方案对加强干预有任何影响，χ2(1， N= 188)= 1.341, p= 0.25。结论：这些研究表明，解决捐赠障碍是一种有效的沟通和招募策略。我们鼓励采血机构在这方面开展宣传活动，而不是侧重于献血者的动机。

期刊介绍： Transfusion Clinique et Biologique, the official journal of the French Society of Blood Transfusion (SFTS): - an aid to training, at a European level - the only French journal indexed in the hematology and immunology sections of Current Contents Transfusion Clinique et Biologique spans fundamental research and everyday practice, with articles coming from both sides. Articles, reviews, case reports, letters to the editor and editorials are published in 4 editions a year, in French or in English, covering all scientific and medical aspects of transfusion: immunology, hematology, infectious diseases, genetics, molecular biology, etc. And finally, a convivial cross-disciplinary section on training and information offers practical updates. Readership: "Transfusers" are many and various: anesthetists, biologists, hematologists, and blood-bank, ICU and mobile emergency specialists...
