[Relations between mental health and work. Review of the literature].

Interest in occupational mental illness has increased as a result also of the technological changes at the workplace. A total of 22 epidemiological studies on this topic were reviewed on the following basis: subject of the study, epidemiological design, type of psychometric scale, results. The authors discuss the methods and constraints of these studies, especially the lack of knowledge on occupational exposure and its relationship to mental health. The need for further studies in order to improve prevention of mental illness at the workplace is stressed.
