Abstract:
【Objective】 To explore effective ways to mobilize more blood donors to become voluntary donors of hematopoietic stem cells (HSCs), so as to increase the HSCs supply in China. 【Methods】 Two scales(the information scale and the control scale) with the same items were designed and both included questions concerning the knowledge of HSCs donation and the level of demand. The information scale indicated the correct answer to these questions, while the control scale did not. A total of 3 000 blood donors in Guangzhou were randomly assigned into the intervention group (n=1 500, filled in the information scale) and the control group (n=1 500, filled in the control scale). 【Results】 Blood donors who filled in the informational scale expressed a higher intention to become HSCs volunteers (MInformation =4.32, SD=0.87; MControl=4.02, SD=0.93, t(529)=3.87, P<0.001). Altruism and perceived need (the degree of HSCs demands) were the moderators of grouping and intention, that is, the information scale made blood donors, with stronger altruism and higher perceived need, more willing to become stem cell volunteers. Perceived risk (the negative impact of HSCs donation on health) was a partial mediator of grouping and intention. The information scale reduced blood donors' anxiety about the risk of HSCs donation, and promoted their intention to become HSCs volunteers. 【Conclusion】 This study proved that the informational scale can effectively mobilize blood donors to become HSCs volunteers.
