Background. Asian American and Pacific Islander women represent a significant at-risk population for breast cancer, with their mortality rates rising while rates fall for all other racial groups. Methods. This 3-year study employed a quasi-experimental design to test the influence of an intervention on screening rates among women age 50 years and older in Southern California compared to Northern California. Results. Despite significant exposure of women to the educational elements in Southern California, the intervention did not increase women’s knowledge, attitudes, or screening behaviors. Conclusions. We discuss several study design and implementation limitations that could have influenced the study’s results.
