Pearson's correlation coefficients Spearman's rank correlation coefficients	BDI of “novel coronavirus”	BDI of “coronavirus”	BDI of “coronavirus pneumonia”
BDI of “novel coronavirus”	1	0.875∗∗ (P < 0.001)	0.84∗∗ (P < 0.001)
		0.847∗∗ (P < 0.001)	0.785∗∗ (P < 0.001)
BDI of “coronavirus”	0.875∗∗ (P < 0.001)	1	0.96∗∗ (P < 0.001)
	0.847∗∗ (P < 0.001)		0.965∗∗ (P < 0.001)
BDI of “coronavirus pneumonia”	0.84∗∗ (P < 0.001)	0.96∗∗ (P < 0.001)	1
	0.785∗∗ (P < 0.001)	0.965∗∗ (P < 0.001)

^∗∗Correlation is significant at the 0.01 level (2-tailed). The first line of the result is Pearson's correlation coefficients and P value, and the second line is Spearman's rank correlation coefficients and P value.
