摘要

The current study aimed to develop and validate a self-reinforcement scale for repeated blood donation (SRS-RBD). In Study 1, six items were created, and the factor structure of SRS-RBD was explored among 155 Chinese student blood donors. In Study 2, SRS-RBD was validated among 164 donors. In Study 3, a total of 850 blood donors were invited to participate in an online-survey measuring SRS-RBD at baseline, and their RBD behavior was captured 6 months later. A two-factor structure of SRS-RBD was established in Study 1 and further validated in Study 2 and Study 3. The SRS-RBD demonstrated satisfactory reliability and validity. A cut-off score of 20 was suggested as having the best performance to identify donors who had a high chance to re-donate. The SRS-RBD can be considered reliable in measuring the self-reinforcement of RBD among blood donors. The scale may be a useful tool in blood donation practice and research programs.
