A Cross-Sectional, Multilevel Analysis of Cigarette Smoking Among U.S. Manufacturing Workers.” Journal of Occupational and Environmental Medicine 52 (7): 740–50. https://doi.org/10.1097/jom.0b013e3181e80842.1076-27521536-5948http://nrs.harvard.edu/urn-3:HUL.InstRepos:41288130Objective: To investigate whether workplace social capital buffers the association between job stress and smoking status. Methods: As part of the Harvard Cancer Prevention Project's Healthy Directions-Small Business Study, interviewer-administered questionnaires were completed by 1740 workers and 288 managers in 26 manufacturing firms (84% and 85% response). Social capital was assessed by multiple items measured at the individual level among workers and contextual level among managers. Job stress was operationalized by the demand-control model. Multilevel logistic regression was used to estimate associations between job stressors and smoking and test for effect modification by social capital measures. Results: Workplace social capital (both summary measures) buffered associations between high job demands and smoking. One compositional item-worker trust in managers-buffered associations between job strain and smoking. Conclusion: Workplace social capital may modify the effects of psychosocial working conditions on health behaviors.en-USJournal Article2019-08-3010.1097/JOM.0b013e3181e80842
