The scientific evidence is in-sufficient () to determine if there is a relationship between the following occupational factors and depressive symptoms/
Demands (several types of demands), Demands (emotional), Distributive justice, Threats, Violence, Irregular, Irregular work hours, Physically demanding work, Pesticides, Solvents, Heavy metals
  1. - There is scientific evidence for an association between exposure and outcome. The result is based on studies of high or moderate quality. The quality of evidence has been upgraded due to consistency of the data (control and job strain) or large magnitude of effect (bullying)
  2. - There is scientific evidence for an association between exposure and outcome. The result is based on studies of high or moderate quality
  3. - It is not possible to determine if there is any association between exposure and outcome. The motivation is that one or several conditions apply: 1) no study fulfilled the inclusion criteria, 2) none of the studies fulfilling the inclusion criteria were relevant to the hypothesis tested in the present review, 3) all relevant studies were of low quality or 4) studies were of high or moderate quality - but one or several limitations applied, e.g. inconsistency of data between studies
