Health protective behaviours during the COVID-19 pandemic: Risk adaptation or habituation?

Area of Science:

• Epidemiology
• Behavioral Science
• Public Health

Background:

• Human behaviors significantly influence infectious disease transmission.
• Understanding temporal changes in Health Protective Behaviors (HPB) during epidemics is crucial.
• Mechanisms like risk adaptation and habituation may explain public response to health threats.

Purpose of the Study:

• To investigate how the epidemiological context influences engagement in HPB.
• To examine the roles of risk adaptation and risk habituation in modifying HPB over time.
• To analyze temporal variations in public responsiveness to health threats during the COVID-19 pandemic.

Main Methods:

• Utilized self-reported data from 25 cross-sectional surveys in France.
• Included representative samples of the adult population (N=50,019).
• Data collection spanned from March 2020 to September 2021.

Main Results:

• Both risk adaptation and risk habituation mechanisms explained temporal variations in social distancing.
• These findings are significant given the distinct cognitive processes underlying each mechanism.
• Public responsiveness to health threats showed notable temporal shifts.

Conclusions:

• The study highlights the importance of understanding psychological mechanisms in public health.
• Incentives are crucial for maintaining HPB and mitigating risk habituation.
• Effective disease control requires sustained public engagement in protective measures over time.
