Public Attitudes and Knowledge About HIV/AIDS in Georgia

Public Attitudes and Knowledge about HIV/AIDS in Georgia is a representative statewide survey conducted by the Kaiser Family Foundation (KFF) as part of a public information partnership with the Georgia Department of Public Health.  KFF researchers designed and analyzed the survey.  Social Science Research Solutions (SSRS), an independent research company, collaborated with KFF researchers on sample design, weighting, and fieldwork.  Both the Kaiser Family Foundation and the Georgia Department of Public Health contributed funding for the survey.

The telephone survey was conducted in English from July 28 – August 9, 2015, among a random digit dial telephone sample of 556 adults ages 18 and older who currently live in the state of Georgia, and included an oversample of Black respondents to ensure enough interviews to be able to report results separately for this population.

The sample employed an overlapping dual-frame (landline and cell phone) design.  In total, 239 computer-assisted interviews were completed via landline and 317 via cell phone, of which 189 were with respondents whose household could be reached only by dialing cell phones.  Both the random digit dial landline and cell phone samples were provided by Marketing Systems Group.  To oversample Blacks, the landline and cell phone samples were geographically stratified by estimated incidence of Blacks, and areas with higher expected incidence were disproportionately sampled.  Interviews were also completed with a callback sample of respondents who had previously completed an interview on the SSRS Omnibus Survey and indicated that they were Black and they resided in Georgia.

All data were weighted adjust for the sampling design (including the Black oversample) and to balance the sample demographics to match estimates for Georgia residents based on data from the U.S. Census Bureau’s August 2013 American Community Survey (ACS).  Parameters used included age, education, race/ethnicity, marital status, phone status, rural area residency, and residence in Atlanta.  The sample was also weighted to match current patterns of telephone use using estimates from the National Health Interview Survey (NHIS).

The margin of sampling error (MOSE) including the design effect is plus or minus 6 percentage points for results based on the total sample.  All statistical tests of significance account for the effect of weighting.  Unweighted Ns and MOSE for key subgroups are show in the table below.  For other subgroups the margin of sampling error may be higher.  Sample sizes and margin of sampling errors 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.
