a field study in the service and production sector 45 work situations in 11 companies with 478 employees were investigated. Characteristics of the companies (e.g. job market situation), of job content (e.g. task variety), and of well-being (e.g. work satisfaction, mental health) were analysed. The aim of the risk analysis was to uncover the relationship between job market, job content and health. The starting point of the investigation was a hypothetical model of the relationships. This model was confirmed by the risk analysis. The model assumes that job content is linked mainly to specific characteristics of well-being, whereas the job market situation is linked mainly to non-specific characteristics of well-being. However, the interaction among job market and job content cannot be proven by risk analysis. Therefore causal analysis were applied to continue the analysis. Causal analysis enables the identification of causal relations through stepwise testing of causal models using partial and semipartial correlation. The results of the causal analyses confirm the interaction among job market and job content referring well-being. They disprove the existence of any direct relationship between job content and health. The effect of job content characteristics on well-being is mediated by the perceived job content. However, a direct causal relationship could be proven between the job market and well-being. A modified causal model emerged which is the starting point for selective health promotion programs and their evaluation in profile studies.
