Improvement of Work Environment

As a result of a literature review on methodology and the effectiveness of work-environment oriented workplace stress reduction, it is suggested that improvement of the work environment is effective in reducing workers' job stressors and psychological and physiological stress reaction, from a limited number of controlled studies including RCT, as well as a number of case studies and before-after comparison studies. An expert-guided, supervisor and worker participated approach also seems effective. The author proposes five practical steps toward an effective improvement of the work environment based on the review. Remaining topics include the need for more well-designed studies, investigation of the relationship between intervention type and outcome, as well as modifying effects according to social situations, and instruments for implementation.
