A review of literature suggests that individual, social, and organizational factors are important to consider in the development of worksite health promotion programs. This article describes a conceptual framework that integrates these factors. The implications of this framework for the development, implementation, and evaluation of worksite health promotion programs and the results of an intervention based on this approach are presented. The results from this study highlight the importance of active employee involvement in all stages of worksite health promotion programs. The findings also indicate that programs need to address the causes, not just the symptoms, of stressful working conditions.
