“…However, the CHIS and NHIS are the only population-based data that bridge the continuum from breast cancer screening to cancer diagnosis. The CHIS and NHIS both ask the same question on self-reported mammography screening and these data have been published routinely as population-level data on screening mammography both among small subsamples as well as national data reported by the CDC (Bleyer & Welch, 2012; Bostean, Crespi, & McCarthy, 2013; CDC, 2012; Courtney-Long, Armour, Frammartino, & Miller, 2011; Eberth, Huber, & Rene, 2010; Ponce et al, 2012; Ryu, Crespi, & Maxwell, 2013). Studies comparing the validity of self-reported mammography with medical records report low incongruences (Bancej, Maxwell, & Snider, 2004) and find that women tend to overreport mammography use, especially racial and ethnic minorities (Ferrante et al, 2008; McPhee et al, 2002; Rauscher et al 2008; Zapka et al, 1996).…”
