In this research, we engaged Black community members and HIV service providers in Canada to evaluate a co-designed, culturally responsive prototype of an mHealth application for HIV prevention. Guided by community-based research and user-centered design principles, we designed a prototype based on findings from an earlier exploratory phase where participants shared their preferences on the content, functionality, and design of a mobile HIV prevention app called MyHealthCore. A mixed-methods approach combining qualitative feedback from semi-structured interviews with quantitative usability pre-testing data guided this formative evaluation of the prototype’s design and user experience with Black community members (N = 4) and HIV service providers (N = 4). Participants rated the prototype as highly usable (76.88, SD = 2.59), and strongly agreed that it was simple, intuitive, and motivating to use for HIV prevention. Participants emphasized trust, privacy, and discretion as essential to adoption, with representation and stigma-free language as facilitators of engagement. Community members described the prototype as empowering and “made for us,” while service providers emphasized its potential for integration into routine HIV health promotion efforts. MyHealthCore demonstrates that when built collaboratively with underserved populations, mHealth interventions can advance health equity and digital innovation by embedding cultural and clinical relevance into digital health solutions.

摘要

In this research, we engaged Black community members and HIV service providers in Canada to evaluate a co-designed, culturally responsive prototype of an mHealth application for HIV prevention. Guided by community-based research and user-centered design principles, we designed a prototype based on findings from an earlier exploratory phase where participants shared their preferences on the content, functionality, and design of a mobile HIV prevention app called MyHealthCore. A mixed-methods approach combining qualitative feedback from semi-structured interviews with quantitative usability pre-testing data guided this formative evaluation of the prototype’s design and user experience with Black community members (N = 4) and HIV service providers (N = 4). Participants rated the prototype as highly usable (76.88, SD = 2.59), and strongly agreed that it was simple, intuitive, and motivating to use for HIV prevention. Participants emphasized trust, privacy, and discretion as essential to adoption, with representation and stigma-free language as facilitators of engagement. Community members described the prototype as empowering and “made for us,” while service providers emphasized its potential for integration into routine HIV health promotion efforts. MyHealthCore demonstrates that when built collaboratively with underserved populations, mHealth interventions can advance health equity and digital innovation by embedding cultural and clinical relevance into digital health solutions.
