We're working hard, but is it hardly working? Why process is critical in the delivery of worksite health promotion programs.

Objective: To evaluate the relationship between the process and outcomes of worksite wellness committees (WWCs) implementing worksite health promotion programs at PPG Industries, Inc.

Methods: We developed two unique tools to understand how WWCs function and to assess their program implementation. We then analyzed survey data from 65 PPG worksites, measuring process and program implementation.

Results: Worksites that scored higher on the process indicator had more robust program implementation.

Conclusions: The WWCs need increased attention from researchers and evaluators. Employers should consider administering worksite health promotion structural assessments to identify gaps in management support and program implementation that may influence program effectiveness.
