Intolerance of uncertainty predicts fear of healthcare settings but not desire for testing during the novel coronavirus pandemic.

The novel coronavirus (COVID-19) pandemic has caused unprecedented uncertainty, and differences in how people cope with this uncertainty will influence the cost of viral pandemics to both individuals and society. The personality trait of intolerance of uncertainty (IU), defined as a dispositional fear of the unknown, has been linked to higher health anxiety and fear of the virus. Although IU may increase the desire for medical information and treatment, during pandemics, this might be weighed against the risk of becoming infected while in a healthcare setting. We examined whether people with higher IU report greater fear of healthcare settings, and show more desire to be tested for the virus. Residents of the United States ( = 149) were surveyed in early May 2020, while most states had active stay-at-home orders. Higher prospective but not inhibitory IU predicted more fear of healthcare settings. The largest effect size, however, was for fear of leaving the home, indicating a general tendency toward fear and avoidance. Fear of leaving the home, perceiving the virus as dangerous, access to testing, and having symptoms were significant predictors of desire for testing.
