*3.2. Participant Worries Regarding COVID-19*

Overall, 85% of participants worried some (48%) or a lot (37%) about getting COVID-19 and 78% worried some (39%) or a lot (39%) about giving COVID-19 to others. The

majority of participants (97%) reported being worried some (18%) or a lot (79%) about having enough food and most (87%) reported being worried some (24%) or a lot (63%) about income loss. Only worry about family or friends getting COVID-19 was significantly correlated with rurality. (x2(2) = 7.687, *p* = 0.021) Among rural participants, 80% reported being worried some (52%) or a lot (28%) about family and friends getting COVID-19, while 67% of non-rural participants worried some (50%) or a lot (17%) about family and friends getting COVID-19.

## *3.3. Perceptions on the Effectiveness of Individual Behaviors for Staying Safe from COVID-19*

We found significant correlations between rurality and perceptions of effectiveness for the behaviors of wearing a face mask (x2(2) = 9.997, *p* = 0.007), limiting time spent indoors in public spaces (x2(2) = 13.903, *p* = 0.001), avoiding large gatherings (x2(2) = 10.006, *p* = 0.007), and limiting the frequency of necessary errands (x2(2) = 9.015, *p* = 0.011). When asked whether wearing a facemask was "effective for keeping you safe from COVID-19", 82% of rural participants reported wearing a facemask was moderately (39%) or highly (43%) effective for protecting against COVID-19, while 75% of non-rural participants reported a facemask was moderately (50%) or highly (25%) effective. When asked about limiting time spent indoors in public spaces, 69% of rural participants perceived this behavior as moderately (42%) or highly (27%) effective for keeping them safe from COVID-19. Among non-rural participants, 55% perceived this behavior as moderately (45%) or highly (10%) effective. In regards to avoiding large gatherings, 68% of rural participants perceived this behavior as moderately (40%) or highly (28%) effective, while 56% of non-rural participants perceived this behavior as moderately (43%) or highly (13%) effective. Among rural participants, 77% reported "limiting frequency of necessary errands requiring public places (e.g., grocery shopping)" was moderately (50%) or highly (27%) effective at keeping them safe from COVID-19, while 65% of non-rural participants reported this behavior as moderately (51%) or highly (14%) effective. We did not find significant associations between rurality and perceptions on the effectiveness of consulting a health care provider, avoiding outdoor public spaces, and avoiding contact with at-risk populations.
