Personality in a naturally occurring strong situation: Unique effects of HEXACO traits on COVID-19 mitigation

The first Italian lockdown during COVID-19 pandemic constituted an example of strong situation. Under this context, we investigated associations of HEXACO personality with COVID-19 mitigation behaviors (self-reported hygiene, distancing, going out). We tested unique associations through regularized regressions and out-of-sample prediction after establishing the best level of analysis (HEXACO traits, facets, items). Personality always explained out-of-sample variance over and above demographics, COVID-related knowledge, concern, impacts, and goals. Hygiene and distancing were best predicted by HEXACO traits, whereas facets constituted the best level for the prediction of going out. In general, honesty-humility (trait or facets) was the clearest predictor of safer behaviors. Results corroborate the relevance of personality even in strong situations, as well as its importance for COVID-19 mitigation.
