[Mental health and work: concepts, evidence and implications for research and practice].

This paper reviews the concepts, evidence and implications regarding mental health at the workplace. The theoretical background with the most common theories (e.g. effort-reward imbalance model and job-demand control model) are briefly reviewed and findings from systematic reviews and from a meta-analysis regarding psychosocial factors at the workplace and common mental disorders, which indicate that psychosocial factors increase the risk of mental disorder are outlined. Implications for primary prevention as well as early intervention and treatment following a stepped care model including a variety of agents from different backgrounds are discussed. Implications to enhance research in the field are outlined.
