Increasing Blood Donor Pledge Fulfillment

Pittman, T. S., Pallak, M. S., Riggs, J. M., & Gotay, C. C. (1981). Increasing blood donor pledge fulfillment. Personality and Social Psychology Bulletin, 7, 2, 195-200.

Two studies conducted during campus blood drives assessed two techniques derived from a commitment and social support analysis that were designed to increase the rate of pledge fulfillment by volunteer donors. A reminder about donation addressed to the individual donor plus two other named donors (Three-Name Reminder) elicited greater pledge fulfillment than a reminder addressed to the individual alone (One-Name Reminder). Similarly, a reminder addressed to the individual that simply stated that two other people would donate at the same time (Group Reminder) also enhanced pledge fulfillment relative to the One-Name Reminder.
