Objective: To examine the effectiveness of an organizational large-scale intervention applied to induce a health-promoting organizational change process.
Design and Methods: A quasi-experimental, “as-treated” design was used. Regression analyses on data of employees of a Dutch dairy company (n = 324) were used to examine the effects on bonding social capital, openness, and autonomous motivation toward health and on employees’ lifestyle, health, vitality, and sustainable employability. Also, the sensitivity of the intervention components was examined.
Results: Intervention effects were found for bonding social capital, openness toward health, smoking, healthy eating, and sustainable employability. The effects were primarily attributable to the intervention's dialogue component.
Conclusions: The change process initiated by the large-scale intervention contributed to a social climate in the workplace that promoted health and ownership toward health. The study confirms the relevance of collective change processes for health promotion.
