How Do Personal Networks Affect Adherence to Epidemiological Measures, Vaccine Hesitancy, and the Risk Assessment of COVID-19?

Abstract

Since the beginning of the COVID-19 pandemic, adherence to
epidemiological measures was proved related to the information
exchanged through personal networks. However, there is still
limited evidence on the effect of specific network properties.
Using data from a randomised national sample of adults in
Croatia (N = 765), we examine the role of various personal
networks attributes with regard to three dependent variables:
risk assessment of COVID-19, adherence to epidemiological
measures and intention to avoid vaccination. We propose
"pandemic discussion networks" as personal networks that
encompass social contacts with whom respondents exchange
pandemic-related information. Network heterogeneity in terms
of the discussants' education level contributed to more protective
behaviour, while network heterogeneity in terms of age
contributed to an inclination towards vaccination. These
associations were confirmed independently of behavioural
homophily in terms of risky health behaviour, which was also
found.
