Healthcare Appointments as Commitment Devices.

Area of Science:

• Behavioral Economics
• Global Health
• Public Health Interventions

Background:

• Self-control problems and commitment challenges hinder demand for essential healthcare services, particularly in low-resource settings.
• Hard commitment devices are often used to address these issues but can lead to financial losses for users.
• Understanding alternative, effective strategies is crucial for improving healthcare access.

Purpose of the Study:

• To evaluate whether ordinary appointments can serve as a substitute for hard commitment devices in increasing demand for healthcare.
• To assess the impact of appointments on HIV testing rates among high-risk men in Malawi.
• To identify which individuals benefit most from appointment-based interventions.

Main Methods:

• A randomized controlled experiment was conducted in Malawi involving high-risk men.
• Participants were randomly offered either HIV testing appointments or hard commitment devices.
• Testing rates and uptake of commitment devices were measured and compared.

Main Results:

• Appointments more than doubled HIV testing rates, demonstrating a significant increase in demand.
• The positive effects of appointments were most pronounced among individuals who sought commitment.
• In contrast, most participants using hard commitment devices forfeited their investments, indicating a failure of these devices.

Conclusions:

• Ordinary appointments are effective substitutes for hard commitment devices, increasing demand for critical healthcare services.
• Appointments address commitment problems without the risk of commitment failure inherent in traditional devices.
• This approach holds significant potential for enhancing healthcare demand and access in developing countries.
