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.

Dr. Derek Griffith is a Founding Co-Director of the Racial Justice Institute, the Founder and Director of the Center for Men’s Health Equity, a Professor of Health Systems Administration and Oncology, and a Member of the Lombardi Comprehensive Cancer Center at Georgetown University in Washington, DC. He earned his Ph.D. from DePaul University in 2002 and completed a Post-Doctoral Fellowship at the University of North Carolina School of Public Health in 2004.

Dr. Griffith’s research focuses on strategies to improve African American men’s health, such as precision lifestyle medicine interventions to prevent and control obesity and other chronic diseases. Specifically, he studies the “links between notions of masculinity or manhood and health among men of color; the role of stress and coping processes in men’s health disparities; and how gender intersects with race, ethnicity, SES and other variables to shape men’s physical and mental health behavior and health outcomes.” 

In a current research project, Dr. Griffith is a Co-Investigator with Dr. Robert Newton from the Pennington Biomedical Research Center in Louisiana and Dr. David Buller from Klein Buendel on a study to develop and evaluate a smartphone app to increase and maintain physical activity in African American. The app is called FitBrothers and will include personalization, chronic disease health information, dietary information, competition activities, and incentives to promote and sustain physical activity. The study is being funded by a Small Business Technology Transfer grant to Klein Buendel from the National Institute on Minority Health and Health Disparities (MD014947; Dr. Robert Newton and Dr. David Buller, Multiple Principal Investigators).

Dr. Griffith has received research grants as the Principal Investigator from the American Cancer Society, the Robert Wood Johnson Foundation, and several institutes within the National Institutes of Health. He has authored over 140 peer-reviewed manuscripts and serves on the editorial boards of several public health and men’s health journals.

Dr. Griffith has received multiple distinguished awards and honors throughout his career, including:

  • The Tom Bruce Award from the Community-Based Public Health Caucus of the American Public Health Association in recognition of his research on eliminating health disparities that vary by race, ethnicity and gender;
  • Recognition as a Fellow of the American Academy of Health Behavior for his significant contributions to the field of health behavior research; and
  • Designation as one of 1,000 Inspiring Black Scientists in America by the Cell Mentor’s Community of Scholars.
