The study confirms the multifactorial nature of vitality at work. Since organizational culture may support self-determination, and cultural aspects themselves are positively associated with vitality, organizational culture seems particular important in promoting vitality at work. Additionally, a healthy lifestyle appears important. The associations between vitality at work and effective personal functioning and sustainable employability endorse the combined health-based, business-related and societal importance of vitality at work.

Organizational social capital was found to be a resource for employees' health, with meaningful business implications.

Internalization of the value of health is important to promote a healthy lifestyle and work style among employees, and has meaningful business implications.

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.

Companies, seen as social communities, are major health promotion contexts. However, health promotion in the work setting is often less successful than intended. An optimal adjustment to the organisational context is required. Knowledge of which organisation-specific factors are relevant to health promotion is scarce. A Delphi procedure is used to identify these factors. The aim is to contribute to more effective workplace health promotion. The identified factors are described and embedded into a practical methodology (Intervention Mapping). A systematic use of these factors (called 'Organisational Mapping') is likely to contribute to more effective health promotion in the work setting.
