Methodology: 2010 Survey of Health Care Consumers
A nationally representative sample of 4,008 American adults, ages 18 and older, was surveyed between December 28, 2009 and January 5, 2010, using a web-based questionnaire. The results were weighted to assure proper proportional representation to the nation’s population, as reflected in the 2006 US Census Public Use Microdata Sample (PUMS) file, with respect to age, gender, income, race/ethnicity and geography. The margin of error around the U.S. point estimates is +/- 1.6 percent at the .95 confidence level.
The survey consisted of 50 questions, with 26 potential follow-up questions. English and Spanish versions were available. Participants were asked about behaviors before attitudes within each topic area to reduce response bias.
Comparisons are made to Deloitte’s 2009 and 2008 surveys wherever possible, but differences in question wording and response scales – used in an effort to improve the survey instrument – preclude direct comparison in some cases until those questions are repeated in future surveys. Questions from the 2008, 2009 and 2010 surveys will be repeated periodically in future surveys to assess how health care consumerism is evolving in the U.S.
