Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Gratitude-Based Thank-You Message
Participants in this group receive a standardized gratitude-based intervention immediately after completing whole-blood donation. The intervention consists of (1) a written thank-you message acknowledging the donor's contribution and emphasizing the life-saving impact of their donation, and (2) a brief vignette illustrating how donated blood benefits patients in need. The purpose of this intervention is to enhance donors' subjective well-being and psychological need satisfaction by reinforcing their sense of autonomy, competence, and relatedness. Participants complete questionnaires at Time 1 (post-donation) and Time 2 (4-22 days later).
Information
A reminder to inform donors that their blood has saved patient's life in a questionnaire.
No Message
Participants in this group complete the standard post-donation procedure and receive no additional message or vignette. They complete the same questionnaires at Time 1 (post-donation) and Time 2 (4-22 days later) as the Intervention group. This arm serves as the comparison condition for evaluating the effect of the gratitude-based intervention on subjective well-being and related psychosocial outcomes.
