Web-Based Study for Improving Mammography Among Korean American Women.

Web-based culture-specific interventions for Korean American (KA) women to improve mammography utilization are not available. An established intervention developed to improve mammography utilizations for Korean American (KA) women was tested via the Web for its efficacy, feasibility, and acceptability. A randomized controlled trial, with a pretest-posttest control group design, was conducted with 136 KA women and their spouses. Intention to have a mammogram within the next 12 months increased significantly in the intervention group compare to controls. Among women whose mammograms had not been updated, 22 % of women in the intervention and 13 % of women in the control group obtained a mammogram at 2-month post-baseline, even though the difference was not statistically significant. The Web-based study educating couples was feasible and could improve KA women's breast cancer screening intention and behaviors. Combining off-line contact for recruitment/data collection with online intervention material could decrease the attrition rate in the future study because the attrition rate in this study was higher than the original study.
