The best way to justify continuing a wellness program would be to demonstrate that the participants:

To justify the continuation of a wellness program effectively, demonstrating that participants have reduced their health risk scores is particularly compelling. This metric directly correlates with the primary goals of wellness programs, which often aim to improve participants' health outcomes.

Reduced health risk scores indicate that the program is having a tangible impact on the participants' overall health. It suggests that individuals are making meaningful lifestyle changes that lead to lower risks for chronic diseases, such as obesity, diabetes, cardiovascular diseases, and other health-related issues. These improvements can be quantified through assessments and screenings, providing concrete data to support the program's effectiveness.

While increased physical activity is important and contributes to overall wellness, it is more of a means to an end—strengthening the participants' health but not necessarily demonstrating measurable health improvements. Similarly, attendance rates and sharing experiences, while valuable for engagement and community building, do not always correlate with better health outcomes. Therefore, focusing on health risk scores provides the most significant evidence for the program's success, making it the strongest basis for justifying its continuation.
