CULTURALLY TAILORED INTERVENTION EFFICACY TO PROMOTE BREAST CANCER SCREENING AMONG AMERICAN INDIAN WOMEN

Abstract

Abstract Purpose The purpose of this project was to develop and evaluate the feasibility and effectiveness of the Mobile Web App Breast Cancer Screening (wMammogram) intervention among American Indian (AI) women. Method: Using a randomized controlled trial design, 122 AI women (40-70 years old) were recruited and randomly assigned to the wMammogram group (n=62) to receive culturally and personally tailored multimedia messages through a mobile web app along with health navigator services or the control group (n=60) to receive a printed educational brochure. Outcome measures included mammogram receipt, intention to receive breast cancer screening after the intervention, and satisfaction with and perceived effectiveness of the intervention. Result: A significantly higher proportion of women who received the intervention (42%, 26/62; p<.01) completed mammograms by the 6-month follow-up compared with the control group (20%, 12/60). The wMammogram group, compared with the control group, reported significantly higher ratings on perceived effectiveness of the intervention (t120=-5.22, p<.001), increase in knowledge (t120=-4.75, p<.001), and satisfaction with the intervention (t120=-3.61, p<.001). The wMammogram group also expressed greater intention to receive a mammogram in the future when it is due (100%, 62/62 vs. 85%, 51/60) and were more willing to recommend the intervention they received to their friends (98.4%, 61/62 vs. 90%, 54/60) compared with the brochure group. These differences were statistically significant. Conclusion Based on our results, a mobile web app-based intervention combined with health navigator service was a feasible, acceptable, and effective intervention mechanism aimed at promoting breast cancer screening in AI women.
