Country: United States
Survey Organization: Synovate and Mathew Greenwald and Associates
Field Dates: September 1–19, 2006
Sample: Privately insured adults ages 21–64. The sample was randomly drawn from Synovate's online sample of 1.5 million Internet users who have agreed to participate in research surveys. The sample was stratified by gender, age, region, income, education, race/ethnicity and then weighted by gender, age, region, income, education, race/ethnicity to reflect the actual proportions in the population. The base sample was complemented with an additional random over-sample, also weighted, of two groups of adults: 1) those with a high-deductible health plan and either an employer-funded HRA or an employer- and/or employee-funded HSA, and 2) those with a high-deductible health plan without an account but with deductibles high enough to meet the qualifying threshold to make tax-preferred contributions to such an account or that are generally associated with HRAs.
Sample Size: 3,158 which included 930 in high-deductible health plans without accounts; 722 in high-deductible health plans with an HRA or HSA; and 1,506 in more comprehensive health plans or those with lower or no deductibles.
Interview Method: Internet survey
