Hypothesis
The Web-based program group will show significantly greater improvement in the outcome measures of diet, stress, and physical activity than the print group.
Conclusion
The Web-based program was more effective than print materials in producing improvements in the areas of diet and nutrition but was not more effective in reducing stress or increasing physical activity.
Supporting Evidence
- The Web-based program showed significantly better results in dietary attitudes and dietary stage of change compared to the print group.
- Both groups improved in dietary measures from pretest to posttest.
- The Web-based program received higher ratings for being informative and appealing.
Takeaway
This study tested a health program on the internet to help workers eat better and be healthier. It found that the online program worked better than paper materials for improving diet.
Methodology
Randomized controlled trial with pretest-posttest comparisons, involving 419 employees assigned to either a Web-based program or print materials.
Potential Biases
Potential for social desirability bias and Hawthorne effect.
Limitations
All dependent measures were self-reports; the test period was limited to three months; and a no-treatment control condition was not included.
