MobileMen and mHealth

Ms. Amanda Brice, Klein Buendel Project Coordinator, is the lead author on a research paper published in the journal mHealth. The paper reports on the development of MobileMen, a mobile app to promote physical activity in African American men.

African American men experience higher rates of chronic diseases including diabetes, cardiovascular disease, and obesity compared to other race and gender groups. This population also has high levels of inactivity, one of the major risk facts for chronic disease. Due to the promise shown by mobile apps in providing tailored and easily accessible health interventions, the authors set out to design an app to help African American men initiate and maintain their physical activity.

The research team conducted focus groups with 24 African American men to gain insight on the features and design aspects to include in the app prototype. They then used an iterative design process to conduct multiple rounds of beta and usability testing to create a prototype that was easy to use, visually pleasing, and culturally tailored. A satisfaction and helpfulness questionnaire and the System Usability Scale (SUS) were used as quantitative measures in addition to qualitative data provided by participants. Tasks were given to participants to test for ability to navigate and use the app features.

The average satisfaction and helpfulness ratings from participants were 3.9/5 and 3.7/5 for beta testing and 4.3/5 and 4.1/5 for usability testing, which met the pre-determined criteria of ≥3.5. Only one of the satisfaction questions, which was about cultural tailoring for African American men, was below the pre-determined criteria (2.7). By round two of usability testing, most tasks were able to be completed by all participants, and the mean SUS score was 90.36 out of 100 which exceeded a priori feasibility criterion of a mean rating of 68.0. The feedback on the finalized features was positive, and participants expressed that they would use the app if it were on the market.

Based on both the qualitative and quantitative data obtained from multiple iterative design rounds, the MobileMen app was easy to use and contained culturally tailored features. It was well received by the target population and deemed ready to be tested on a larger scale for effectiveness. Full descriptions of the methods, analyses, and findings can be found in the mHealth paper.

MobileMen Project Protocol

MobileMen Project Protocol

African American men are at higher risk for serious health conditions such as cardiovascular disease, diabetes, and stroke compared to non-Hispanic White men. Physical activity is a modifiable health behavior that has been shown to decrease chronic disease risk. Still, engagement in physical activity is alarmingly low in African American men. While interventions to improve physical activity engagement are effective in several populations, very few have been tailored to the unique needs of African American men. Even fewer have leveraged mobile health apps, despite African American men’s interest in and willingness to use such technologies for health improvement.

Now a multi-disciplinary research team from Klein Buendel, Pennington Biomedical Research Center, and three universities is conducting a comparative effectiveness trial that aims to evaluate MobileMen, a physical activity promotion app tailored to the needs and preferences of African American men. The team has published the plans and methods for the trial in JMIR Research Protocols.

The trial compares the MobileMen app to a commercially available physical activity promotion app with similar features but without culturally tailored components. Specifically, the study is recruiting a sample of 100 “low active” (less than 7500 steps per day) African American men aged 30 years or older from Baton Rouge, Louisiana and its surrounding communities. All participants are given a Fitbit Charge 6 wearable activity tracker to assess daily physical and steps. Participants are randomly assigned to either the MobileMen intervention app or a comparator app. The intervention period is six months, during which participants will interact with their assigned mobile app.

MobileMen includes features such as digital badges earned for physical activity, tangible prizes like exercise equipment, challenges among participants, goal setting, nutrition, physical activity, and behavior change educational information in text, audio, and video formats.

Participants complete assessments at baseline and at six months after random assignment. Assessments include objective measurements of daily steps and minutes of moderate to vigorous physical activity, quality of life, dietary measures, self-efficacy for fruit and vegetable consumption and physical activity, and autonomous motivation for physical activity. Detailed descriptions of measures and methods can be found in the JMIR Research Protocols paper.

Mobile apps are a widely accessible means to disseminate culturally tailored physical activity promotion interventions to various populations, including African American men. MobileMen has the potential to impact physical engagement in African American men, to help improve the overall health and chronic disease risk in this underrepresented population.
