The integrated model: implications for worksite health promotion and occupational health and safety practice.

Within a single firm it is common to find both occupational safety and health and worksite health promotion interventions operating in isolation from one another, with different intervention targets, methods, and personnel. Overcoming the segmentation of the two fields will require, among other things, the promulgation of an overarching model of work and health. The purpose of this article is to describe an integrated model and to show how it can be applied to improve worksite health interventions for both occupational safety and health and worksite health promotion. Practice examples from both fields are used to illustrate interventions that focus on different areas of the model (individual behavior, psychosocial, organization, and contextual factors). It is argued that occupational safety and health and worksite health promotion practitioners need to develop more comprehensive interventions and rigorously evaluate these programs to determine if they are more effective than programs with a more narrow focus.
