Predicting Plasma Donation Intention Using an Extension of the Theory of Planned Behavior

  • The urgent need for plasma and its components is increasing rapidly all over the world. This is due to demographic changes, which bring about an imbalance between eligible donors and possible future recipients. Hence, these changes pose a great challenge in meeting the demand for plasma and plasma-derived products in the future. As plasma cannot be synthesized, recipients depend on voluntary plasma donors. In order to ensure a sufficient supply of plasma considering the ongoing process of aging population, it is crucial to understand why people engage in donation behavior and which factors influence their decision to maintain the donor career. The current study investigates the determinants of plasma donation intention using an extended version of the theory of planned behavior. As the study is conducted in cooperation with Octapharma Plasma GmbH, a subsidiary of one of the largest worldwide operating providers for plasma preparations, the analysis is based on the company’s donors only. By using an online questionnaire, data of N = 1153 plasma donors is surveyed in order to examine the hypotheses. Multiple hierarchical regressions reveal significant predictors for plasma donation intention for all donors combined and also for both first-time and repeat plasma donors. Across all donor stages, self-efficacy turns out to be the predominant predictor for future donation intention. Moreover, the satisfaction with the last donation influences all groups of plasma donors in their decision of career maintenance. Therefore, organizations should pay attention to these components, developing strategies to enhance both donors’ self-efficacy and donation satisfaction.
