Data quality is a major concern for any survey system, particularly as use of the data becomes more widespread. The purpose of this study was to assess the reliability and validity of selected HIV-related measures from the Behavioral Risk Factor Surveillance System (BRFSS) through a detailed review of prior research. The BRFSS is an on-going, state-specific population-based, random telephone survey that collects information monthly from U.S. adults. Established in 1984, AIDS-related questions were incorporated in 1990, and HIV-related sexual risk behavior questions in 1997. The quality of the questions, as they appear on the BRFSS, has not been evaluated directly, nevertheless, there has been work on similar, and in some cases identical, questions from other surveys. Specifically, we examine the reliability and validity of self-reported perceived risk of HIV infection, HIV testing, number of sex partners, and condom use. In terms of reliability, limited work in the area shows that self-reported HIV testing appears to be reliable. Reliability of other HIV-related sexual behaviors appears to be generally good. For validity, HIV testing self-reports accord relatively well with the behavior. Validity of other HIV-related sex behaviors is mixed. While perceived risk of HIV infection appears to closely match actual risk, more research is needed on this topic. Overall, the findings suggest areas for additional methodological research. Not only is it important to determine levels of HIV risk, it is also important to ensure that the data are both reliable and valid in our continuing efforts to understand and prevent the disease.
Learning Objectives: At the conclusion of the presentation, the participant should be able to: 1) identify the Behavioral Risk Factor Surveillance System and recognize HIV-related measures in the survey 2) assess the reliability and validity of selected HIV-related measures on the BRFSS 3) understand how the issue of data quality is important for these measures
