Abstract Background. Korean American women have one of the highest breast cancer mortality rates and lowest breast cancer screening rates among American women. In response to the need to enhance breast cancer screening, this study aims to develop and test a 7-day mobile phone application (app)-based Mammogram (mMammogram) intervention designed to promote breast cancer screening among Korean American women. To date, mobile app technology has not been used for mammogram promotion. Methods. Using FBM Model, we developed a mammogram intervention designed to increase knowledge of breast cancer screening, intent to receive mammogram, and the receipt of a mammogram. A series of focus groups were conducted to inform the development of the intervention. A randomized controlled trial was conducted with baseline, one week post-intervention, and 6-month follow-up testing among 120 Korean American women who were aged 40 and older and had not had mammograms within the last 2 years. The intervention group (60) received an individually and culturally tailored text messages via mobile app with health navigation services. The control group (60) received a brochure including information on breast cancer, screening guidelines, and a list of clinics that offer low-cost or free mammography without health navigation services. Results. At one week post-test, statistically significant between-group differences were found; intervention subjects reported higher scores of knowledge in breast cancer and screening guideline than subjects in control group (mean differences: 1.70, p &amp;lt; 0.05). No statistical between group differences identified in intention to receive screening. However, significant between-group difference was found in the receipt of mammogram at 6-month follow-up test; 40.0% (24/60) of the intervention group received mammograms whereas 25.0% (15/60) of the brochure group received mammograms after intervention (p &amp;lt; 0.05). 100% of the participants expressed satisfaction with the intervention and 98.3% reported that they would recommend the program to their friends. Conclusions. This study provides evidence of the effectiveness and feasibility of the mammogram intervention with health navigation services in promoting breast cancer screening. Mobile application-based intervention is a promising tool to increase both knowledge and receipt of mammograms. Given the widespread usage of mobile phone among minority populations, a mobile phone-based health intervention could be an effective method of reaching hard-to-recruit populations with high breast cancer burden, using individually tailored messages that cover broad content areas and overcome restrictions to place and time of delivery.
