Study inclusion criteria • Multi-component programming • Workplace setting only • Reasonably rigorous study design • Original research results • Examines economic variables • In peer review journal • Use comparison or control group • Use statistical analysis • Must be replicable approach • At least 12 months in duration

  10. Meta-Evaluation criteria • Quality of research design • Sample size • Quality of baseline delineations • Quality of measurements • Appropriateness and replicability of interventions • Length of observational period • Recentness of experimental period

  11. Example of Meta-Evaluation criteria #2 Sample size

  21. Summary of key points • There are a large number of health improvement and economic return studies now in the literature. • They are of differing quality and rigor. • However, all of them with a few exceptions document positive findings, but with different magnitudes. • They have been conducted in a wide variety of industries and settings with varying size work groups. • The more rigorous the evaluation effort the greater the health effect and economic return. • The higher the participation levels the greater the health effect and economic return. • Studies are now being reported in other developed nations that parallel US study findings. • There are a number of programming strategies that will enhance the economic return from these types of programs. • Therefore, Yes - Wellness programs do work.
