Blood Center of Zhejiang Province, Zhejiang, China (People's Republic)
Background/Case Studies: Donor retention is an effective way to improve blood safety and maintain a stable blood supply. However, the prevalence of repeated blood donation (RBD) is low. To improve RBD, it is imperative to identify prospective factors of RBD. By identifying the prospective multidimensional factors with a longitudinal study design, effective intervention to improve RBD can be designed. Based on social cognitive theory, protection motivation theory and prosocial theories (altruism theory, moral identity theory), the present study aimed to identify prospective multidimensional factors influencing RBD among blood donors in China.
Study
Design/Methods: A total of 850 blood donors were recruited from Hangzhou where the blood donation sites were located in China and were invited to participate in an online survey measuring the prosocial factors (altruism, moral identity), SCT factors (knowledge, observational learning, outcome expectation, maintenance self-efficacy, self-reinforcement, collectivism, influence of policy, physical and social environment) at baseline, and their RBD behavior was followed up by checking the blood donation record from the database of Blood Center in Zhejiang Province 6 months later. Univariate and multiple logistic regression analyses were conducted to test the associations between demographic characteristics, prosocial factors, SCT factors and RBD intention at baseline and RBD behavior at 6-month follow-up.
Results/Findings: The prevalence of RBD behavior at 6-month follow up was 22% (185). After adjusting for the significant demographic variables and baseline RBD behavior, the prosocial factor of moral identity (AOR=1.36, 95% CI: 1.00~1.84, p < 0.05), SCT factors of maintenance self-efficacy (AOR=1.44, 95% CI: 1.13~1.83, p < 0.01), negative self-reinforcement (AOR=0.76, 95% CI: 0.61~0.95, p < 0.01), collectivism (AOR=1.30, 95% CI: 1.09~1.55, p < 0.01) and influence of policy (AOR=1.18, 95% CI: 1.03~1.35, p < 0.05) were significant in predicting RBD behavior. Donors who have an intention to RBD at baseline were 4.44 (95% CI: 2.26~8.73, p < 0.001) times more likely to exhibit RBD behavior during follow-up period. Conclusions: The prevalence of RBD behavior is low among blood donors in China. Interventions aiming at promoting RBD behavior should consider improving moral identity, maintenance self-efficacy, collectivism, influence of policy and RBD intention, and reducing negative self-reinforcement.
