Correlations between different dimensions of the extended PMT scale

Variables	A	B	C	D	E	K
A	1
B	−0.05**	1
C	0.23**	0.09**	1
D	0.31**	−0.02	0.23**	1
E	0.24**	0.08**	0.16**	0.70**	1
K	0.42**	0.01	0.28**	0.76**	0.67**	1

Note: A: perceived severity; B: perceived susceptibility; C: response cost; D: response efficiency; E: self‐efficacy; and K: knowledge of SARS‐CoV‐2 RAST; the correlation coefficients were calculated by the covariance matrix of each variable; and the p value was calculated by t‐test in the SEM analysis.

Abbreviations: PMT, protective motivation theory; RAST, rapid antigen self‐testing; SARS‐CoV‐2, severe acute respiratory syndrome coronavirus 2; SEM, structural equation model.
