## Results
### Regression Analyses  
We tested linear regression models that predict changes in COVID-19 on seven lifestyle indicators separately (Table 2). \begin{table}
\begin{tabular}{c c c c c c} \hline \hline
**Model** & **Ext** & **Agr** & **Con** & **Neu** & **Ope** \\ \hline Stress management & 0.34 a & 0.06 & 0.32 a & \(-\)0.19 a & 0.10 a \\ Restorative sleep & 0.14 a & 0.05 & 0.20 a & \(-\)0.17 a & 0.01 \\ Social support & 0.40 a & 0.15 a & 0.20 a & \(-\)0.10 a & 0.10 a \\ Environmental exposures & 0.05 & 0.01 & \(-\)0.11 a & 0.10 a & \(-\)0.02 \\ \hline \hline \end{tabular} Note: a \(p<0.05\), b \(p<0.01\), c \(p<0.001\). Ext = Extraversion, Agr = Agreeableness, Con = Conscientiousness, Neu = Neuroticism, Ope = Openness to experience.

Table 2: Linear regression models that predict a healthy lifestyle during the COVID-19 pandemic. Extraversion, agreeableness, and conscientiousness were positively predicted while neuroticism negatively predicted diet and nutrition, R\({}^{2}\) = 0.11, F (5, 1209) = 32.14, \(p\) < 0.001. Substance abuse was positively predicted by agreeability and conscientiousness and was negatively predicted by extraversion, R\({}^{2}\) = 0.05, F (5, 1209) = 11.64, \(p\) < 0.001. Extraversion and conscientiousness positively predicted while neuroticism negatively predicted physical activity, R\({}^{2}\) = 0.09, F (5, 1209) = 24.40, \(p\) < 0.001. Stress management was positively predicted by extraversion and conscientiousness, and negatively predicted by neuroticism, R\({}^{2}\) = 0.20, F (5, 1209) = 58.61, \(p\) < 0.001. Extraversion and conscientiousness positively predicted while neuroticism negatively predicted restorative sleep, R\({}^{2}\) = 0.07, F (5, 1209) = 17.77, \(p\) < 0.001. Social support for healthy practices was positively predicted by extraversion, agreeableness, and conscientiousness, R\({}^{2}\) = 0.18, F (5, 1209) = 54.06, \(p\) < 0.001.
