ThaiHealth acts as a catalyst as well as a change agent. These roles arise from the fact that there are responsible people implementing health promotion activities and that ThaiHealth should not repeat their works. Therefore, ThaiHealth will make use of its flexibility in management and budget to help initiate new ideas, facilitate and help transform health promotion opportunities into concrete actions. Also, it can be said that ThaiHealth focuses on its roles as an assistant and facilitator, rather than being an actor.
