Hierarchical multiple linear regression coefficients for DASS-21 Stress, Anxiety, and Depression, and PCL-5 scores.

^aCompared with workers. ^b Compared with sleep duration between 6 and 8 h.

Notes: The different background colors represent each block in the hierarchical regression. Intercepts were omitted from the table. Coefficients are standardized βs, which mean the amount of change in the outcome variable (in standard deviations) when the predictor increases one unit (or, in case of dichotomous variables, change from no to yes, for example). Standardized βs are used to easily compare the effect size of each predictor. Statistically significant p-values are highlighted in bold.
