Individuals prefer COVID-19 mitigation strategies that reduce health risks and offer financial compensation. This study demonstrates the effectiveness of web-based Respondent Driven Sampling and Discrete Choice Experiments for gathering public health preferences.
Area of Science:
- Public Health
- Behavioral Economics
- Epidemiology
Background:
- Nonpharmaceutical interventions (NPIs) like social distancing were crucial for controlling COVID-19 spread.
- Understanding public preferences for NPIs is vital for effective policy-making.
- Traditional sampling methods often struggle to reach diverse populations for such studies.
Purpose of the Study:
- To pilot a web-based Respondent Driven Sampling (RDS) approach combined with a Discrete Choice Experiment (DCE) to assess individual preferences for COVID-19 mitigation strategies.
- To evaluate the feasibility and potential of RDS and DCE for scalable, generalizable public health preference research.
- To identify key factors influencing participant choices regarding NPIs.
Main Methods:
- A web-based Discrete Choice Experiment (DCE) was administered to participants recruited via Respondent Driven Sampling (RDS) across three countries.
- A rank-ordered mixed logit model was employed to analyze the choice data.
- The study involved university students and staff, with a focus on engagement and response rates.
Main Results:
- Participants prioritized mitigation strategies that minimized COVID-19 risk, such as increased sheltering-in-place.
- Financial compensation from the government was a significant factor in preference.
- Minimizing personal health (mental and physical) and financial problems were also key preferences.
Conclusions:
- Web-based RDS and DCE are effective tools for recruiting participants and gathering data on public health preferences.
- The methodology shows potential for scale-up to achieve nationally-representative estimates.
- Findings highlight the need for policies that balance public health goals with economic and personal well-being.
