Wearable Devices as Facilitators, Not Drivers, of Health Behavior Change

Mitesh S. Patel, David A. Asch, Kevin G. Volpp

In a commentary in the Journal of the American Medical Association, Mitesh Patel, David Asch, and Kevin Volpp discuss the validity of claims that wearable devices promote long-term healthy behaviors.

The authors conducted a web-based multi-period insurance purchasing experiment. Participants were told the probability and resulting losses of a hurricane occurring and were informed that these were stable from period to period. The authors contrast the model of informed expected utility maximization with alternative behavioral models of choice as explanations for what they observe. The...

Through a cluster-randomized control trial, the authors compare the weekly sales of targeted products - milk, ready-to-eat cereal, frozen meals, in-aisle beverages, and checkout cooler beverages - for supermarkets that received a six-month, in-store, marketing intervention, with those that did not. The intervention, provided to four randomly assigned stores in low-income, high-minority areas,...
