The overarching aim of the United States-Work, Stress, and Health (US-WSH) project is to examine the effects of workplace conditions on stress and health. As the primary survey, data were collected from 1,800 working adults in the United States in 2005. Approximately 20 months later, all of these individuals were sought for a second interview. Successful interviews were achieved with approximately 71 percent of the original sample. 

We applied the stress process framework as a guiding theoretical model for the project. It posits that exposure to stressful role conditions can harm emotional and physical functioning. 

Other arms of this study rely on different sources of secondary data in the United States like the National Study of the Changing Workforce and the US General Social Survey.
