A Spanish-language adaptation of an HIV mHealth app achieves good usability and acceptability for Latinx PWH while surfacing engagement barriers for iterative design

Narrative synthesis #

This is a usability/user-centered-design claim, not an effectiveness claim. The quantitative SUS score (75, "good") and the predominantly positive perceived-impact and strengths themes establish usability and acceptability for a Spanish-speaking Latinx population of PWH; the barriers and suggestions themes (privacy, low literacy, lack of personal connection, repetitiveness; requests for interactivity and personalization) constitute the actionable engagement findings that the user-centered process was designed to surface. The "positive impact on medication adherence" figures are self-reported perceptions elicited by direct prompting, not measured adherence outcomes; the paper explicitly defers actual outcome measurement to future work.

"Future research can identify how these changes impact usability and over time, how mHealth participation can enhance engagement in care and clinical outcomes." (Kristen, 2023)
