Use of Behavioral Economics in Repeat SARS-CoV-2 (COVID-19) Antibody Testing in Disadvantaged Communities

University of Southern California·interventional·Posted May 25, 2021·Updated Aug 14, 2024

In Brief

A clinical study evaluating Family Risk Messaging, Personal Risk Messaging, and 2 other interventions for SARS-CoV-2. Completed, enrolled 2,164 participants across 1 site.

Detailed Summary

Repeat testing for SARS-CoV-2 antibodies in disadvantaged communities will help identify active and recovered infections over time, and as more is understood about antibody protection, it may help identify persons who have immunity. Many questions about social barriers and behavioral facilitators remain unanswered. This project aims to evaluate the effectiveness of risk-based messaging and incentives that promote repeated testing for SARS-CoV-2 antibodies, as well as to understand social and behavioral determinants of COVID-19 testing and variations within sub-groups of this population.

Interventions

Family Risk Messagingbehavioral

Family risk framing may engender concern for loved ones. It may also make it easier to mentally simulate family burdens with COVID-19 such as knowing how several people in the family becoming sick could adversely affect the lives of everyone in the family. Households randomized to family risk messaging will receive the following message: "Antibody testing will help you understand your family's risk of getting COVID-19."

Personal Risk Messagingbehavioral

Personal risk framing may engender concern for oneself. Households randomized to personal risk messaging will receive the following message: "Antibody testing will help you understand your risk of getting COVID-19."

Loss Protectionbehavioral

Household members are offered a baseline incentive with a 90% (9 in 10) chance of $60 and receive insurance on winning the baseline incentive for repeat antibody testing.

Lottery Incentivebehavioral

Household members are offered a baseline incentive with a 90% (9 in 10) chance of $60 and receive a bonus lottery incentive with a 4 small (1 in 25) chance of winning $150 for repeat antibody testing.
