At this time, there are no interactive mobile apps designed to increase informed decisions about colorectal cancer screening among women. Colorectal cancer is the third leading cause of cancer death among women. The study's purpose was to explore the usability, acceptability, and satisfaction with a mobile app designed to increase colorectal cancer screening informed decisions among 50- to 64-year-old women. Using previous research, an interactive mobile app to increase informed decisions about colorectal cancer screening was developed and pilot tested among African American and Caucasian women (N = 41). In total, 80.6% of women strongly agree/agreed that the mobile app made them think about colorectal cancer screening, 83.8% strongly agree/agreed that the mobile app provided enough information to make a decision about colorectal cancer screening, and 86.1% strongly agree/agreed that the mobile app could help them talk to their provider about colorectal cancer screening. Participants (63.2%) identified family/spouse as who they would talk to about their colorectal cancer screening decision. Participants found the mobile app easy to use and useful in making colorectal cancer screening decisions. Social support is important when making decisions about colorectal cancer screening. Healthcare professionals need new strategies, such as mobile apps, that engage patients, have the potential to increase patient–provider communication, and increase colorectal cancer screening adherence.
