Impact of a print intervention to increase annual mammography screening among Korean American women enrolled in the National Breast and Cervical Cancer Early Detection Program

Background: Although Korean American women have one of the lowest rates of mammography screening, only few interventions have been developed for them. We developed a theory-based Korean-language print intervention to increase annual mammography screening with the goal to disseminate it through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Methods: Korean American staff and patients at a community clinic advised on the content and layout of the brochure. We pilot tested the intervention from July to September 2005 at a community clinic in Koreatown, Los Angeles County that provides free mammograms through the NBCCEDP. The proportion of Korean American women who received a repeat mammogram during the intervention period was compared to the pre-intervention period using a NBCCEDP database. Results: We found a non-significant 6 percentage point increase in repeat screening from 32% to 38%. A debriefing survey with a subsample of 59 women revealed that only 32% recalled receipt of the brochure and a subsequent investigation revealed that only about 60% had identical address information in the NBCCEDP records and in their charts. Conclusions: Although dissemination of print information through NBCCEDP is very feasible, the reach and effectiveness of the intervention was limited due to incorrect or outdated address information.
