Risk perception and reappraisal during the COVID-19 pandemic in southeast Alaska: Self-identified determinants of risk and protective health behaviors.

Social and cultural context shapes how communities perceive health, well-being, and risk. Risk reappraisal can occur over time as a product of new information and improved understanding. We investigate risk perception and protective behaviors in Lingít Aaní (Southeast Alaska) during the first year of the COVID-19 pandemic. Surveys were circulated at two time points: (1) April-June 2020, before COVID-19 reached epidemic levels in the region, and (2) November 2020-February 2021. Ordinary least squares (OLS) regression models were used to analyze how demographic characteristics of the respondent population were related to risk perception. OLS models were again used to predict how individuals engaged in protective behaviors while controlling for risk perceptions. Controlling for demographic characteristics, risk perception increased as age increased for perceived risk of getting sick and dying from COVID-19, males perceived lower risk in general for all tested variables, and Alaska Native respondents perceived higher risk than non-Alaska Native respondents. Controlling for risk perception, results for protective behaviors were mixed; however, the strongest association identified was that knowing someone with a positive COVID-19 diagnosis increased protective behaviors. Between the two time points, risk perceptions increased significantly for variables related to oneself, others, and community members becoming infected with COVID-19. Protective behaviors like traveling less than normal, buying more cleaning products, and engaging in more subsistence gathering significantly increased. Identifying patterns of risk perception and protective behaviors, and especially how they change over time, are critical to developing place-specific public health recommendations, action, and preparedness plans against future infectious threats.
