Objective: In this pilot study we tested the influence of manipulating anticipated regret on organ donor registration behavior.
Method: A simple web-based experimental trial was conducted. Nonorgan donors were allocated to a simple anticipated regret manipulation versus a theory of planned behavior or a control condition. The main outcome measure was registration on the U.K. organ donor register at 1-month follow-up.
Results: A simple anticipated regret manipulation led to a significant increase in organ donor registrations.
Conclusion: Interventions utilizing anticipated regret may have the potential to significantly increase organ donation rates.
