The change towards the information society and the use of information technology has increased the psychological and social demands of work. Valid and practical methods and instruments for measuring psychosocial stressors at work, as well as methods with which to intervene and prevent their adverse effects are increasingly needed. The measurement methods can be questionnaires, interviews or joint discussion seminars. Intervening with psychosocial stressors, especially through participatory approaches, has proved to be fruitful. Examples of applied approaches are, e.g. the survey-feedback method, and the so-called conference method based on democratic dialogue. In addition, the role of the consultant is important to ensure a successful intervention process. Evaluation of the whole intervention is needed in order to find out the consequences of the intervention and to derive useful information about the feasibility of the applied intervention methods.
