The protective role of social network factors during the COVID-19 pandemic in the United States

The present study examined the relationship between COVID-19 threat perception, isolating health precautions, and loneliness. As a test of the stress-buffering hypothesis (Cohen & Wills, 1985), this study also examined if social network factors representing various aspects of social support moderated, or weakened, the relationship between threat perception, isolating health precautions, and loneliness. Participants (N = 1149) provided information about themselves, as well as 15 other people they know via an online survey. We found that structural and compositional social network factors, density, number of close alters, network threat perception, network covid cautiousness and number of vaccinated alters all negatively related to loneliness. Further, using moderated mediation analyses, we found that network threat perception and network covid cautiousness moderated the indirect relationship between threat perception and loneliness through precautions. At high levels of these factors, the mediation was less likely to be significant suggesting that the social network factors may buffer people from the loneliness that sometimes comes with engaging in isolating health precautions in response to the perceived threat of COVID-19.
