We will conduct a 4.5-year community-based RCT to study the impact of intervention approaches (small-group video discussion vs. single video mode) on mammography used among Chinese immigrant women. The small-group video discussion will be led by trained Chinese community health educators and trained bilingual research staff using a standardized structured protocol at all sites. In the single video mode, we will mail the intervention materials to women to view and/or read at home. We will recruit 974 Chinese women through our strong and well-established Chinese community partnerships in the metropolitan areas of Washington, DC (Lead PI: Dr. Judy Wang, Georgetown University-GU), New York (Site PI: Dr. Grace Ma at Temple University), and southern California (Site PI: Dr. Annette Maxwell, University of California, Los Angeles-UCLA). Participants' eligibility are listed under "eligibility criteria". We will not enroll US-born Chinese women as they are least likely to face cultural and language barriers to mammography and less likely to engage in our small-group discussion, which will be conducted in Chinese languages. Also, we will not enroll short-term visitors as our study involves four interviews over a 2-year period.
