KFF COVID-19 Vaccine Monitor: In Their Own Words
This KFF COVID-19 Vaccine Monitor: In Their Own Words was designed and analyzed by public opinion researchers at the Kaiser Family Foundation (KFF). The survey was conducted January 14-18, 2021 using the SSRS Opinion Panel, a nationally representative panel of U.S. adults age 18 or older recruited using probability-based sampling techniques. For the Kaiser Family Foundation CVM Survey, SSRS invited adult panelists in the U.S., targeting by gender, age, race, education, and region. SSRS regularly monitored data collection to check for demographic composition of the sample and data quality. Cases determined to be poor-quality, as defined by surveys with a length of interview of less than 33% of the mean length of interview and with invalid text responses were removed from the final data. In total, 2,152 panelists were invited and 1,009 respondents completed the full questionnaire online on January 14-18, 2021. 982 surveys were completed in English and 25 survey were completed in Spanish. Panelists were compensated for their participation, with incentives distributed by the SSRS Opinion Panel through their standard procedures.
The margin of sampling error including the design effect for the full sample is plus or minus 4 percentage points. Numbers of respondents and margins of sampling error for key subgroups are shown in the table below. For results based on other subgroups, the margin of sampling error may be higher. Sample sizes and margins of sampling error for other subgroups are available by request. Note that sampling error is only one of many potential sources of error in this or any other public opinion poll. Kaiser Family Foundation public opinion and survey research is a charter member of the Transparency Initiative of the American Association for Public Opinion Research.
