Main Study Results
We concluded that both simulated monetary and psychological incentives had positive impacts on participants’ willingness to bring their medications during a simulated visit to the primary care clinic. The simulated monetary incentive at the level of US $15 was stronger than the psychological incentive.We also found strong evidence that the simulated psychological incentive could be strengthened by the inclusion of the loss frame. In addition, results were consistent between the willingness scores and the reverse-coded scores. Thus, we conclude that participants understood the questions and their answers to simulated incentives were valid and not the result of a random process.
