Background Increased physical activity (PA) levels are associated with reduced risk and improved survival for several cancers; however, most Americans engage in less than the recommended levels of PA. Using interactive voice response (IVR) systems to provide personalized health education and counseling may represent a high-reach, low-cost strategy for addressing physical inactivity and cancer disparities in disproportionately burdened rural regions. However, there has been a paucity of research conducted in this area to date. Objective The aim of this study is to design, develop, and test the usability of an IVR system aimed at increasing PA levels in the rural Alabama Black Belt. Methods A pilot version of the IVR system was used to assess initial feasibility and acceptability. Detailed exit interviews were conducted to elicit participant feedback, which helped inform the development of a substantially upgraded in-house IVR system. This refined IVR system was then subjected to a sequential explanatory mixed methods evaluation. Participating rural county coordinators and research staff (N=10) tested the usability of the IVR system features for 2 weeks and then completed the System Usability Scale and qualitative semistructured interviews. Results The study sample comprised mostly African American people, women, rural county coordinators, and research staff (N=10). Participants rated the IVR system with a mean score of 81 (SD 5) on the System Usability Scale, implying excellent usability. In total, 5 overarching themes emerged from the qualitative interviews: likes or dislikes of the intervention, barriers to or facilitators of PA, technical difficulties, quality of calls, and suggestions for intervention improvement. Message framing on step feedback, call completion incentives, and incremental goal-setting challenges were areas identified for improvement. The positive areas highlighted in the interviews included the personalized call schedules, flexibility to call in or receive a call, ability to make up for missed calls, narration, and PA tips. Conclusions The usability testing and feedback received from the rural county coordinators and research staff helped inform a final round of refinement to the IVR system before use in a large randomized controlled trial. This study stresses the importance of usability testing of all digital health interventions and the benefits it can offer to the intervention.

Voice Response

BACKGROUND Physical inactivity and related cancer incidence and mortality rates are disproportionately high in the U.S. Deep South, a rural, medically underserved region with a large African American population compared to the rest of the nation. Given this region’s lower rates of literacy and Internet access, Interactive Voice Response (IVR)-automated telephone-based interventions have the potential to help overcome physical activity intervention barriers (literacy, internet access, costs transportation) but have yet to be extended to rural, underserved populations, such as the Deep South. Thus, extensive formative research was conducted to develop, and beta test the Deep South Interactive Voice Response System Supported Active Lifestyle (DIAL) intervention in preparation for dissemination in rural Alabama counties OBJECTIVE To describe the design and rationale of the ongoing efficacy trial of the DIAL intervention. METHODS The 2-arm randomized controlled trial will compare a 12-month physical activity intervention versus a wait-list control condition in 240 underactive adults from 6 rural Alabama counties. The DIAL intervention is based on the Social Cognitive Theory and includes IVR-automated physical activity phone counseling (daily in months 0-3, twice weekly in months 4-6 and weekly in months 7-12) and support from local rural county coordinators with the UAB O’Neal Comprehensive Cancer Center Community Outreach and Engagement Office. The primary outcome is weekly minutes of moderate-to-vigorous intensity physical activity (7-Day PAR, accelerometry) at baseline, 6 months, 12 months, and 18 months. Rural Active Living Assessments will be conducted in each rural county to assess walkability, recreational amenities, and inform future environment/policy efforts. RESULTS Start up activities (hiring/training staff, purchasing supplies) were completed in 2019. Study recruitment and assessments began in September 2020 and are ongoing. CONCLUSIONS IVR-supported phone counseling has great potential for addressing physical activity barriers (e.g., culture, literacy, cost, transportation) and reducing related rural health disparities in this region.

New Strategies

Introduction: Cardiac rehabilitation improves outcomes for patients with ischemic heart disease or heart failure, but is underused. New strategies to improve delivery of cardiac rehabilitation are needed. We developed a mobile application for technology-facilitated home cardiac rehabilitation and sought to determine its usability. Methods: We recruited patients eligible for cardiac rehabilitation who had access to a smartphone, tablet, or computer with internet access to participate in usability testing of the mobile application. The mobile application includes physical activity goal setting, logs for physical activity and health measures, health education, reminders, and feedback (Figure). Participants were introduced to the mobile application and then observed while completing pre-specified tasks with the mobile application. Participants completed the System Usability Scale (0-100), rated likelihood to use the mobile application (0-100), and participated in a semi-structured interview. Based on participant feedback, we made iterative revisions to the mobile application. Results: We conducted usability testing in 13 participants. The first version of the mobile application was used by the first 5 participants, and revised versions were used by the final 8 participants. From the first version to revised versions, task completion success rate improved from 44% to 78% (p=0.05), System Usability Scale improved from 54% to 76% (p=0.04), and rated likelihood of using the mobile application remained high at 76% and 87% (p = 0.30). Interview responses revealed a need for introductory training ( “Initially, training with a technical person, instead of me relying on myself”) and on-demand help (“ If I had problems I’d try to find out how to fix it on this or call you” ). Additionally, many participants were interested in sharing data with providers (“ I can show my doctor what I’ve been working on ”). Conclusions: With participant feedback and iterative revisions, we significantly improved the usability of a mobile application for cardiac rehabilitation. Patient expectations for using a mobile application for cardiac rehabilitation include introductory training, on-demand help, and sharing data with providers. Iterative mixed-method evaluation may be useful for improving the usability of health technology.
