Note. CES-D = Center for Epidemiological Studies Depression scale; CI = confidence interval; MCS = mental component score; OR = odds ratio; PCS = physical component score; PR = prevalence ratio. The organization of work indicators are not standardized; therefore, the associations presented are for a 1-unit change in the independent variable.

^aExcludes self-employed; for perceived supervisor control n = 273; for work safety climate n = 269.

^bRelative risk regression models with Score test.

^cNominal logistic region models with Wald χ² test.

^dLinear regression models with F test.
