Summary

This study investigates the psychological effects of blood donation among adult donors at the Guangzhou Blood Center. The primary objective is to examine whether a brief gratitude-based intervention delivered after donation enhances donors' subjective well-being (SWB) and basic psychological need (BPN) satisfaction. Participants who complete a whole-blood donation are randomly assigned to either an Intervention group, receiving a standardized gratitude reinforcement message accompanied by a vignette emphasizing the life-saving impact of donation, or a Control group that receives no additional message. All participants complete questionnaires at Time 1 (immediately after donation) and at Time 2 (4-22 days later), assessing SWB and related psychosocial variables.
