A rising chorus of people (the usual suspects — Goetzel, O’Donnell etc.) say you don’t need an ROI from wellness, but here is an essay in Employee Benefit News pointing out why you do, citing three distinct reasons, each sufficient on its own.
By contrast to these three strong arguments in favor of demanding an ROI, the best argument against demanding an ROI from wellness is that you can’t get one, which explains the opposition from those usual suspects. They were all about ROIs before it was proven that you can’t get one, but that was then and this is now.
Here is one thing that doesn’t need an ROI: screening according to US Preventive Services Task Force guidelines. Ironically, that’s also the one thing that those very same usual suspects are opposed to. For them, it’s overscreening today, overscreening tomorrow, overscreening forever.
