Preventing Cardiovascular Disease Among Urban African Americans With a Mobile Health App (the MOYO App): Protocol for a Usability Study

Digital Health App to Address Disparate HIV Outcomes Among Black Women Living in Metro-Atlanta: Protocol for a Multiphase, Mixed Methods Pilot Feasibility Study

BACKGROUND

Cisgender Black women in the southern United States are at heightened risk for HIV and adverse sexual and reproductive health outcomes. Mobile health interventions that target HIV risk while being adapted to the needs and lived experiences of Black women are remarkably limited.

OBJECTIVE

The study aims to refine SavvyHER, a mobile app for HIV prevention, with Black women residing in high HIV incidence areas of Georgia and evaluate the feasibility, acceptability, and usability of SavvyHER. This paper describes the procedures implemented to conduct this research.

METHODS

Community-based participatory research tenets guide this multiphase study to finalize the development of what we hypothesize will be an effective, sustainable, and culturally relevant HIV prevention and optimal sexual health and reproductive wellness app for Black women. This multiphased, mixed methods study consists of 3 phases. The first phase entails focus groups with Black women to understand their preferences for the functionality and design of a beta prototype version of SavvyHER. In the second phase, an app usability pretest (N=10) will be used to refine and optimize the SavvyHER app. The final phase will entail a pilot randomized controlled trial (N=60) to evaluate the app's feasibility and usability in preparation for a larger trial.

RESULTS

Findings from preliminary focus groups revealed educational content, app aesthetics, privacy considerations, and marketing preferred by Black women, thus informing the first functional SavvyHER prototype. As we adapt and test the feasibility of SavvyHER, we hypothesize that the app will be an effective, sustainable, and culturally relevant HIV prevention, sexual health, and reproductive wellness tool for Black women.

CONCLUSIONS

The findings from this research substantiate the importance of developing health interventions curated for and by Black women to address critical HIV disparities. The knowledge gained from this research can reduce HIV disparities among Black women through a targeted intervention that centers on their health needs and priorities.

Peer Group Support Intervention to Reduce Cardiovascular Disease Risk for African American Men According to Life's Simple 7 in Faith-Based Communities

BACKGROUND AND PURPOSE

Adverse cardiovascular health disparities persist for African American men. Although changing health behaviors is perhaps one of the most effective methods to prevent cardiovascular disease (CVD)-related deaths, previous behavior change programs targeting single or multiple CVD risk factors in target groups have had mixed success. The purpose of this pilot study was to determine whether a multi-faceted peer group intervention model based on American Heart Association's Life's Simple 7 was feasible, safe, acceptable, and efficacious in producing meaningful risk reduction for African American men.

METHODS

A convenience sample of 24 African American men with at least one CVD risk factor participated quasi-experimental study having peer intervention vs. nonequivalent comparison groups, with pretest-posttests at two church sites in Minneapolis, MN (MPLS) and Washington, D.C. (DC). Feasibility, safety, acceptability, and potential efficacy were assessed by examining completion of peer group sessions, adverse events, attendance, attrition, within and between-group changes in measures using nonparametric statistics.

RESULTS

All twenty-four men completed the study with no study-related adverse symptoms and medical events. The peer groups had moderate to high attendance, and the peer program evaluation was highly positive among participants. Between baseline and 6-months, there were significant differences between the intervention and the comparison group in cholesterol levels and weights (p = .041, p = .034, respectively) at one site (DC). There were no significant between-group changes at the other site (MPLS).

IMPLICATION FOR PRACTICE

The multi-faceted peer support intervention was feasible, acceptable, and shown to have potential efficacy to reduce CVD risk for highly motivated African American men. Future studies with a larger sample size are needed to test the effectiveness of this intervention model to reduce CVD risk among African American men.

Telehealth experiences of providers and patients who use augmentative and alternative communication

OBJECTIVE

We explore the telehealth experiences of adults who use augmentative and alternative communication (AAC) and clinicians who work with people using AAC.

MATERIALS AND METHODS

We conducted semistructured, online interviews with 6 adults who use AAC and 8 clinicians who provide telehealth services to people who use AAC between July and September 2020. Participants were located in the United States and the United Kingdom. All participants had engaged in 2 or more telehealth visits in the past 6 months. We used an inductive, thematic approach to analyze the interview data.

RESULTS

Our findings reveal that (1) telehealth is an essential service, (2) technology causes barriers, (3) policies meant to protect actually inhibit, and (4) remote monitoring devices have the potential to mitigate risks.

DISCUSSION

Telehealth systems created for persons without disabilities do not provide equitable access to everyone. Telehealth should be flexible enough to allow patients to use the communication modality that best meets their needs. We suggest that healthcare systems think of the healthcare ecosystem as one which includes a variety of telehealth options in addition to traditional in-person clinical visits.

CONCLUSIONS

The benefits of telehealth for people who use AAC are substantial and should be an option for ongoing health care. However, the accessibility of telehealth technologies needs to be improved. Designers should view telehealth as part of a broad healthcare ecosystem, which includes in-person, telehealth, and remote health monitoring technologies. Designers should also include AAC users in the design and development process. Telehealth policies should encourage multimodality access to health care and address funding concerns.

Sign of the times: Community engagement to refine a cardiovascular mHealth intervention through a virtual focus group series during the COVID-19 Pandemic

Background

African-Americans are underrepresented in mobile health intervention research studies which can perpetuate health inequities and the digital divide. A community-based, user-centered approach to designing mobile health interventions may increase their sociocultural relevance and effectiveness, especially with increased smartphone use during the coronavirus disease 2019 pandemic. We aimed to refine an existing mobile health intervention via a virtual focus group series.

Methods

African-American community members (n = 15) from churches in Minneapolis-St. Paul and Rochester, Minnesota were enrolled in a virtual (via videoconferencing), three-session focus group series over five months to refine a cardiovascular health-focused mobile health application (FAITH! [Fostering African-American Improvement in Total Health!] App). Participants accessed the app via their smartphones and received a Fitbit synced to the app. Participants engaged with multimedia cardiovascular health-focused education modules, a sharing board for social networking, and diet/physical activity self-monitoring. Participant feedback on app features prompted iterative revisions to the FAITH! App. Primary outcomes were app usability (assessed via Health Information Technology Usability Evaluation Scale range: 0–5) and user satisfaction.

Results

Participants (mean age [SD]: 56.9 [12.3] years, 86.7% female) attended a mean 2.8 focus groups (80% attended all sessions). The revised FAITH! App exceeded the goal Health Information Technology Usability Evaluation Scale score threshold of ≥4 (mean: 4.39, range: 3.20–4.95). Participants positively rated updated app content, visual appeal, and use of social incentives to maintain engagement. Increasing user control and refinement of the moderated sharing board were identified as areas for future improvement.

Conclusions

Community-partnered, virtual focus groups can optimize usability and increase participant satisfaction of mobile health lifestyle interventions that aim to promote cardiovascular health in African-Americans.
