Note: Max re-scaled R2s are as follows: Model 1, receipt ever=0.75; Model 1, receipt within 2 years=0.44; Model 2, receipt ever=0.76; Model 2, receipt within 2 years=0.45.
a
Model 1 adjusted for baseline screening status, lay health worker agency, language proficiency, years in the U.S., education, employment, marital status, family history of breast cancer, and household clusters
b
Model 2 adjusted for all covariates in Model 1, plus changes in knowledge and media exposure scores
LHWO, lay health worker outreach; ME, media education
