Notes: ^∗p < 0.05, ^∗∗p < 0.01, and ^∗∗∗p < 0.001. ΔR² was the change of R square, β was standardized regression coefficients, B was unstandardized regression coefficients, and SE was standard error of mean (the same below). ^aDemographic variables include type variables, working department, and shift pattern (i.e., the 8 h three-shift or 12 h two-shift scheduling pattern) and continuous variable (i.e., working duration as a nurse). Because the working department containing six types of departments was a dummy variable, the intensive care unit (ICU), emergency intensive care unit (EICU), emergency department, radiotherapy department, and rehabilitation department were coded as 1 in turn while the other departments as a reference were coded as 0. The 8 h three-shift and 12 h two-shift scheduling patterns were coded as 0 and 1, respectively. ^bHCC referred to hair cortisol content. ^cSA×HCC referred to the interaction between surface acting and hair cortisol content.
