Study Overview
Brief Summary
In this proposed work, the investigators plan to generate experimental evidence about trust and overuse of healthcare. The protocol described below is for the first phase of this work to establish the feasibility of modifying feelings of trust via a vignette.
Detailed Description
The investigators will engage survey participants by recruiting from among the "Workers" registered with Amazon Mechanical Turk (MTurk). These are paid participants who chose to participate in this anonymous, low-risk activity. After pilot testing on a small set of Workers, the investigators will field the full survey using a randomized design to test hypotheses about the investigators ability to manipulate trust experimentally.
Individuals eligible as participants will be over the age of 18 years, able to read and respond in English, and have had one or more visits with a doctor in the past 3 years.
Survey
The survey has three parts. The investigators will use Qualtrics to develop the survey vignette and use the randomization feature of Qualtrics to randomize the participants when the participant clicks on the link to Qualtrics.
- Vignette Participants will be randomized to view one of sixteen vignettes. The vignettes describe a clinical encounter and vary four attributes, each of which has two levels.
