First author (year) Focus of research Research findings (confidence intervals)
Shenson (2005) Reliability and validity testing of immunization questions Test/retest agreement on vaccination questions was 73%; Self-reports had a sensitivity of .75 and specificity of .83 when compared against medical records.
Bradbury (2005) Test/ retest of colorectal cancer screening tests Variation in reliability estimates due in part to time period between test/retest:
k = .55-.69
Cronin (2009) Validity testing of mammography screening using registry rates and BRFSS rates Estimates of BRFSS over reporting of mammography:
16% women 40-49
25% women 70-79
Fahimi (2008) Validity testing of immunization questions from BRFSS, NHIS Influenza vaccine prevalence:
BRFSS (66.9-68.2)*
NHIS (63.2-66.0)*
Pneumonia vaccine prevalence:
BRFSS (62.7-64.1)*
NHIS (55.3-58.3)*
