A Mobile App (MyPeer) Co-Designed With Immigrant Adolescents for Better Sexual and Reproductive Health: Usability Study.
Article in JMIR formative research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdolescents require comprehensive sexual and reproductive health (SRH) education to successfully transition from puberty into adulthood. However, they often experience barriers and challenges while trying to promote their SRH or access SRH services. Such challenges are amplified among youth from migrant backgrounds, who may further be constrained by societal stigmas and cultural taboos regarding SRH. Mobile health interventions have the potential to provide culturally relevant, accessible, and evidence-based SRH educational resources; however, few SRH mobile apps in Canada are co-designed with immigrant youth or meaningfully integrate their voices and lived experiences.
objectiveWe aimed to co-design a culturally relevant and evidence-based mobile app with immigrant adolescents to provide accurate SRH resources. In this paper, we present the findings of the usability testing of our SRH mobile app-MyPeer.
methodsThroughout our study, we used a community-based participatory research approach and implemented the principles of human-centered design to co-design our mobile app. For our usability study, we recruited immigrant adolescents and interest holders working with the target population. Adolescents participated in moderated focus group discussions (FGDs) and interest holders evaluated the app's quality using the standardized Mobile App Rating Scale (rating components on a scale of 1-5). All FGDs were audio-recorded and later analyzed to implement changes in the app. Mobile App Rating Scale (MARS) scores and responses were analyzed descriptively to evaluate the app's engagement, functionality, aesthetics, quality of information, and subjective app quality.
resultsOverall, 25 adolescents and 17 interest holders participated in this usability study. We analyzed the findings from the FGDs and categorized them into four categories: (1) navigation and interface, (2) SRH information quality and learning, (3) technical performance, and (4) accessibility and multimedia usability. Adolescents found the app visually appealing and the interface easy to navigate. They appreciated interactive features, such as quizzes, and the presentation of information through various media (eg, videos and infographics). However, they also identified technical issues, such as map glitches and navigation inconsistencies, and requested deeper content on SRH topics. The data from the MARS checklist completed by interest holders were analyzed descriptively. The app received the highest scores in the domains of functionality, with mean scores of 4.3 (performance and navigation); engagement, with mean scores of 3.7 (interest); and aesthetics, with mean scores of 4.1 (graphics) and 3.9 (visual appeal). The lowest rated items were customization, with a mean score of 2.5, and interactivity, with a mean score of 3.1.
conclusionsOur app-MyPeer-has promising usability and appeal for adolescents looking for SRH information. Incorporating feedback from youth and content experts helped identify both technical refinements and content requirements. Our findings support the app's potential as a scalable, youth-centered SRH digital tool and emphasize the value of participatory design in youth digital interventions.
