Short answer
When designing interventions or evaluating their impact, consider that societal value is not uniform and can be influenced by the characteristics of the end-user, and be mindful of how your research methods might shape the perceived value.

The public's perceived value of health gains is influenced by the age and severity of illness of the recipient, with different valuation methods yielding varying degrees of impact. This innovation & markets research insight is drawn from a 2010 study published in Health Technology Assessment. Using Mixed-methods survey-based research (qualitative and quantitative) with 587 participants for the relativities study, 409 for the valuation study., researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing interventions or evaluating their impact, consider that societal value is not uniform and can be influenced by the characteristics of the end-user, and be mindful of how your research methods might shape the perceived value.
Public values health gains differently based on recipient age and illness severity
The public's perceived value of health gains is influenced by the age and severity of illness of the recipient, with different valuation methods yielding varying degrees of impact.

Key Findings
- 01Discrete choice questions indicated that age and severity of illness had a limited impact on respondents' valuation of QALY gains beyond the health gain itself.
- 02Matching questions revealed a strong impact of age and severity of illness on the valuation of QALY gains, with significant differences in how gains were weighted for different groups depending on the aggregation method used.
- 03The study assessed the feasibility of using WTP to value QALYs, suggesting it is a viable approach for understanding public preferences.
Application
Design takeaway
When designing interventions or evaluating their impact, consider that societal value is not uniform and can be influenced by the characteristics of the end-user, and be mindful of how your research methods might shape the perceived value.
How to apply
When developing new healthcare products or services, conduct user research that explores not just functional needs but also societal value perceptions, potentially using methods like discrete choice experiments or contingent valuation to understand how factors like age and condition severity influence perceived worth.
Project actions
- 01When researching user needs, consider exploring not just functional requirements but also the broader societal value or importance users place on the problem you are solving.
- 02If your design project involves evaluating the impact or benefit of a solution, think about how you might measure or understand the 'value' beyond just usability or performance metrics.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Employed multiple valuation methods to triangulate findings.
- +Used a nationally representative sample for the relativities study.
Limitations
The findings might be specific to the healthcare context and the cultural values of England. The convenience sample in the valuation study limits generalizability. Different methods of asking questions can lead to different answers, making it hard to pinpoint a single 'true' value.
Reliability & validity
The use of multiple methods (discrete choice, matching, WTP, standard gamble) enhances the validity of the findings by providing different perspectives on value. However, the divergence between discrete choice and matching results suggests potential issues with reliability or sensitivity of specific methods to certain variables. The use of a convenience sample in the valuation study may limit external validity.
Think critically
How might the findings of this study be applied to non-healthcare design contexts where the 'value' of a product or service might also be perceived differently by various user groups?
Design Principles
"Incorporate stakeholder value elicitation that accounts for diverse recipient characteristics and employs robust methodologies to ensure findings reflect genuine societal preferences."
Understanding how societal values are assigned to health interventions is crucial for resource allocation in healthcare and public policy. This insight informs the development of more nuanced and socially acceptable frameworks for evaluating the worth of health technologies and treatments.
What This Means for Your Design
When you're designing something that helps people, how much people think it's 'worth' can change depending on who it's for (like if they're old or very sick). Different ways of asking people what they think can give different answers.
How to use in your project
- 1.Use this research to justify the importance of considering user demographics and health states when designing health-related products or services.
- 2.Reference the study's findings on valuation methods to inform your own user research approach, particularly if you need to quantify the perceived benefit of your design.

Paragraph starter
This research highlights the complex nature of valuing health gains, demonstrating that societal preferences are not uniform and can be significantly influenced by recipient characteristics such as age and illness severity. The study's findings, particularly the divergence between discrete choice and matching methods, underscore the importance of carefully selecting research methodologies when attempting to quantify user value or societal benefit in a design project.
