Mental health trend differences due to workplace psychosocial stressors. Unadjusted and adjusted effects of year (± 95%CI) on mental health from each model. Model I is the unadjusted trend over time (i.e., the mental health trend). Model II is the trend adjusted for non-work related factors (age, sex, length of job tenure) held constant at their mean value. Model III is adjusted for the same non-work related factors as well as job control held constant at the highest value. Model IV is adjusted for job demands held constant at the lowest value (and the non-work related factors). Shaded areas represent 95 percent confidence intervals
