Adapting an m-Health Intervention for Spanish-Speaking Latinx People Living with HIV in the Nonurban Southern United States.

Background: Latinx people in the United States are disproportionately diagnosed with HIV and are more likely to experience worse HIV-related health outcomes. Although m-health has demonstrated success in improving HIV care, a gap remains in the development of m-health platforms tailored to Latinx populations. Methods: We conducted formative study to guide the adaptation of an evidence-based m-health intervention, PositiveLinks (PL), for Spanish-speaking Latinx people living with HIV (PLWH). Spanish-speaking Latinx PLWH in the nonurban Southern United States completed semistructured interviews and viewed a demo version of the m-health intervention. Qualitative analysis was performed using a grounded theory approach. Emerging themes were identified in four topic areas: (1) prior experiences with technology, (2) desired m-health features, (3) experiences with prototype app, and (4) iteration of prototype. Results: All PLWH who participated (n = 22) were born outside the continental United States. Participants included 10 men, 10 women, and 2 transgender participants. Mean age was 41.1 years (standard deviation 11.6 years). Participants expressed concerns about privacy, a need for reliable information, and interest in practical m-health features such as appointment and medication reminders. After trialing the Spanish-language PL prototype, participants reported that peer support and positive reinforcement were strong motivators to use the app. The ability to individualize the app to meet one's own needs was also considered important. Conclusion: This formative study provides baseline attitudes about m-health among Latinx PLWH as well as desired m-health features. m-Health interventions are acceptable to Spanish-speaking PLWH and involving the target population in a user-centered formative process led to improvements in app accessibility and usability.
