Stepwise linear regression results of certificate severity and perceived COVID-19 severity, benefit: safe if immunity obtained through vaccination, benefit: economic recovery, employed or self-employed, and income after COVID-19a.
| Variable | β (SE) | 95% CI | 2-tailed t test (df)b | P value |
| Perceived COVID-19 severity | 0.2506 (0.0505) | 0.1513 to 0.3498 | 4.9600 | <.001 |
| Benefit: safe if immunity obtained through vaccination | 0.1594 (0.0325) | 0.0955 to 0.2233 | 4.9000 | <.001 |
| Benefit: economic recovery | 0.1585 (0.0344) | 0.0909 to 0.2261 | 4.6100 | <.001 |
| Employed or self-employed | –0.2343 (0.0715) | –0.3747 to –0.0939 | –3.2800 | .001 |
| Income after COVID-19 | –0.1280 (0.0408) | –0.2082 to –0.0478 | –3.1400 | .002 |
| (Constant) | 1.6911(0.2292) | 1.2408 to 2.1414 | 7.3800 | <.001 |
aThe adjusted R2 of this regression is 22.76%. Employed or self-employed is a dummy variable that equals 1 if the respondent was either employed or self-employed at the time of the survey and 0 if they are either retired or unemployed.
bThe degree of freedom (df) of this regression model is 520.
