Interactive Effects of Productivity and Work Engagement on Mediation Analysis using Chronic Stress as Explanatory variable.

Productivity, stress, and work engagement play important roles in corporate health. In this study, we have investigated, on the basis of survey data, interactive-effect relationships among productivity, stress, and work engagement. Survey results obtained from 301 samples self-report questionnaires (including the WHO Health and Work Performance Questionnaire: HPQ; the Perceived Stress Scale: PSS; and the Utrecht Work Engagement Scale: UWES) were analyzed using mediation analysis. Results suggest that the interactive positive effects of productivity and work engagement were roughly equal, and that stress decreased both productivity and work engagement. Revealing the relationships among productivity, stress, and work engagement contributes to the efforts of occupational health physicians and of workers in human resource departments trying to plan effective and preferential interventions in order to improve employee working conditions.
