To standardize the OR estimates, scores for each scale were divided by its standard deviation (SD) so that the ORs estimate the likelihood of outcome experienced per 1 SD change (see “Methods”)
Model 1: No covariates included in model
Model 2: adjusted for age, sex, race/ethnicity (non-Hispanic white vs. other), and job group (nurse vs. other)
Model 3: adjusted for age, sex, race/ethnicity (non-Hispanic white vs. other), job group (nurse vs. other), and musculoskeletal comorbidity
Model 4: adjusted for age, sex, race/ethnicity (non-Hispanic white vs. other), job group (nurse vs. other), musculoskeletal comorbidity, and CES-D score
