ABSTRACT
Objective@#To explore the relationship between voluntary blood donation and autonomous motivation based on self-determination theory, so as to provide insights into optimizing voluntary blood donation recruitment. @*Methods@#Participants meeting the blood donation criteria were selected from blood stations and medical institutions in Hangzhou City, Jiaxing City and Quzhou City, Zhejiang Province. A self-designed questionnaire based on self-determination theory was used to collect basic information, awareness and source of blood donation knowledge, autonomous motivation and controlled motivation. The correction between autonomous motivation and voluntary blood donation was analyzed using a multivariable logistic regression model.@*Results@#A total of 986 participants at ages of 18-55 years were surveyed, including 730 females (74.04%) and 256 males (25.96%). Among them, 705 participants (71.50%) had experience of voluntary blood donation. The mean score for blood donation knowledge was (5.76±1.17) points, and the total motivation score for blood donation was (58.21±8.17) points, with autonomous motivation scoring (40.86±5.46) points and controlled motivation scoring (17.35±3.26) points. Multivariable logistic regression analysis identified gender (female, OR=0.419, 95%CI: 0.273-0.644), occupation (medical profession, OR=4.027, 95%CI: 2.440-6.646), blood donation knowledge (OR=1.307, 95%CI: 1.159-1.475) and autonomous motivation (OR=1.074, 95%CI: 1.033-1.116) as factors affecting voluntary blood donation. @*Conclusions@#Autonomous motivation may promote voluntary blood donation. In blood donation recruitment efforts, it is vital to enhance autonomous motivation and make appropriate use of controlled motivation.
