Relevance of psychosocial factors at work for workers' health.

At the end of the 1970s, the World Health Organization (WHO) held an interdisciplinary forum in Stockholm, with the aims of discussing the infl uence of psychosocial factors on health, formulating measurements and proposing inclusive healthcare policies based on these factors (WHOa 1976). In 1980, the International Labour Organisation and WHO published a document in which they drew attention to the adverse effects of work-related psychosocial factors (International Labour Organisation5 1986). According to this document, both of these international organizations agreed that “growth and economic progress do not depend only on production, but also on the living and working conditions, health and wellbeing of workers and members of their families”. The document stated that not only the physical, chemical and biological risks present at work but also various psychosocial factors were important in relation to workers’ health.
