Mobile Phone Multimedia Messaging Intervention for Breast Cancer Screening

Korean American (KA) women have among the highest breast cancer mortality rates and lowest breast cancer screening rates of U.S. American women across racial/ethical groups. This innovative project seeks to harness mobile phone technology as a means to take preventative health care to a new level among this population. Using the Fogg Behavioral Model this study proposes to develop a mobile phone-based intervention designed to motivate KA women to undergo an annual mammogram (mMammogram). The overall study aim is to develop and assess the feasibility and effectiveness of a 7-day long mMammogram intervention designed to persuade KA women to undergo breast cancer screening.

Specific aims over the three-year period include the following: (1) The first year will be devoted to intervention and protocol development. A major emphasis in year 1 will be developing the community advisory board (CAB), conducting a series of pre-intervention focus groups, and working with pertinent persuasive technology consultants to develop and pilot-test the intervention. (2) The second year and the first half of the third year will focus on delivery of the intervention. (3) the second half of the third year will be devoted to data analysis and dissemination.

Participants in the control group will receive the mailed print brochure about breast cancer screening and community resources.

Text messages delivered via mobile app to participants designed to inform them about breast cancer screening and encourage them to schedule a mammogram.

Breast cancer knowledge will be measured by means of McCance, Mooney and Smith's ten-item "Breast Cancer Knowledge" test.

Culture-specific attitudes toward breast cancer screening, such as modesty, will be measured utilizing six items from Tang and colleagues and fatalistic attitudes toward breast cancer will be measured by means of three items from Taylor and colleagues.

We will measure participant intent to undergo screening by use of an adapted version of the transtheoretical model.

Inclusion Criteria: Korean American immigrant women Aged 40-79 Residence in Minnesota Possession of mobile phone with text-message function Possession of active email account Exclusion Criteria: Mammogram receipt within the past 2 years
