Health values and prospect theory: a comment

Area of Science:

• Health economics
• Behavioral economics
• Decision theory

Background:

• Prospect theory is a behavioral economic theory that describes how people choose between probabilistic alternatives involving risk.
• Treadwell and Lenert (2023) posited that community members, unlike patients, tend to undervalue health gains within the prospect theory framework.
• This assertion was made in a recent publication in Medical Decision Making.

Discussion:

• This commentary challenges the universality of Treadwell and Lenert's claim regarding health improvement valuation.
• The authors demonstrate that the underestimation of health gains by community members is contingent upon specific preference functions.
• Arguments are presented against using the current health state as the default reference point in prospect theory applications to health.

Key Insights:

• The relationship between prospect theory, health valuations, and reference points is more nuanced than previously suggested.
• Preference functions significantly influence how individuals, including community members and patients, perceive the utility of health improvements.
• The choice of an appropriate reference level is critical for accurate application of prospect theory in health economics.

Outlook:

• Further research is needed to explore the diverse preference functions and their impact on health valuation.
• Investigating alternative reference points beyond the current health state could refine prospect theory models in healthcare.
• Understanding these nuances is vital for developing effective health policies and interventions.
