Reliability and validity studies of general health assessment and health care access estimates
First author (year) Focus of research Research findings (confidence intervals)
Mucci (2006) Reliability of self-reported health insurance coverage Self-reports of enrollment agreement .93
Type of plan self-report reliability .79
Clements (2006) Reliability of self-reported HMO health care plan Comparison of self-reports to external data
k =.87
Test/retest agreement 78%
Fahimi (2008) Validity of prevalence of health insurance coverage No health insurance
BRFSS (18.4-19.1)*
NHIS (18.7-20.0)*
No medical care due to cost
BRFSS (14.8-15.4)*
NHIS (7.4-8.2)*
Salomon (2009) Comparison of trends of general health in BRFSS and other national surveys; Comparison of prevalence of BRFSS and other national surveys Prevalence of “fair” or “poor” health/ males:
NHIS (11.3-12.7)*
BRFSS (15.9-16.8)*
Prevalence of “fair” or “poor” health/ females:
NHIS (12.9-14.1)*
BRFSS (16.6-17.2)*
BRFSS more likely to show increased proportions of self-reports of “fair” or “poor” health
