Psycho-mental stressors and increased perceived stress in workplace settings may determine the onset and course of stress-related mental and psychosomatic disorders. For the description of psycho-mental stressors three distinct models have widely been used in the analyses of the matter: the Demand-Control-Model by Karasek and Theorell, the Effort-Reward-Imbalance Model by Siegrist, and the Model of Organisational Justice.The interactional or social dimension in work-place settings can be seen as a cross-sectional dimension to the above mentioned models. Here, social conflicts and mobbing, as specific forms of interactional problems, are of importance.Besides measures of primary prevention which can be derived from applying the above mentioned models, attention is paid increasingly to secondary and tertiary preventive measures in work-place settings. Concepts such as the psychosomatic consultation-hour within the context of workplace showed to be effective measures for the early detection of people at risk or early stages of e. g. stress-related psychosomatic disorders.Furthermore, step-wise reintegration of members of the work-force play an important role within the effort to retain the ability to work and the workplace of individuals who suffered from stress-related mental disorders, as it has to be stressed that working and social interactions at the workplace may well be a resource that enhances and stipulates psycho-mental well-being and mental health.This CME-Article describes the above mentioned models and discusses selected perspectives of preventive measures to avoid stress-related mental disorders in members of the work-force. © Georg Thieme Verlag KG Stuttgart · New York.
