Inequality averse and compassionate blood donor: implication for interventions.

Area of Science:

• Behavioral Economics
• Social Psychology
• Health Sciences

Background:

• Blood donors exhibit distinct cooperative preferences compared to non-donors.
• Understanding these preferences is crucial for developing effective blood donor interventions.
• Previous research suggests potential differences in resource sharing and fairness perceptions.

Purpose of the Study:

• To determine the dominant cooperative preference (compensation vs. punishment) in blood donors.
• To test an intervention strategy based on advantageous inequality aversion to promote blood donation.

Main Methods:

• Study 1: Compared compensation and punishment preferences in blood donors and non-donors (N=372) using a third-party game.
• Study 2: Assessed the feasibility of an intervention leveraging advantageous inequality aversion (N=151).

Main Results:

• Blood donors showed a preference for compensation, unlike organ donors who preferred punishment.
• The advantageous inequality aversion intervention increased blood donation propensity, particularly in non-donors.

Conclusions:

• Blood donors clearly favor direct helping via compensation.
• This finding supports the development of targeted interventions to enhance blood donor recruitment and retention.
