"The objective of the study was to investigate the content, criterion, and construct validity of a single-item measure of stress symptoms. Such a concise measure would be useful in monitoring stress at work. The criteria for validity were convergence with conceptionally close measures, the plausibility of associations with health and work characteristics, and the power to discriminate between groups.The stress-symptoms item showed satisfactory content, criterion and construct validity for group-level analysis. It is suggested that the longer scales used to measure psychological stress can be replaced with it in survey research."

"This booklet describes the work ability index, a method developed by the Finnish Institute of Occupational Health for providing an assessment of how well a worker is able to perform his or her work. The index is determined on the basis of answers to a series of questions which take into account the physical and mental demands of the work and the worker's health status and resources. The score calculated from the responses depicts the worker's own concept of his or her work ability. Other topics discussed: example of the determination of the index; reference values; follow-up measures."
