Abstract
Inflammatory Bowel Disease (IBD) is a long-term condition affecting the digestive system. Staying on prescribed treatment helps prevent flare-ups and improves health. Mobile health (mHealth) apps can support treatment adherence with features like reminders and medication tracking. This project designed and evaluated an mHealth app to support medication adherence for people with IBD. The app was built in React Native, a framework for building mobile apps. We evaluated it through task-based usability testing, standardized questionnaires—the mHealth App Usability Questionnaire (MAUQ) and the Perceived Competence Scale (PCS)—and semi-structured interviews. Fifteen participants completed nine tasks to assess the app’s usability and functionality. On 7-point rating scales, average scores were 5.54 on the MAUQ and 5.62 on the PCS, indicating high perceived usability and competence. There was also a strong positive relationship between perceived usability and perceived competence: participants who rated the app as easier to use also felt more capable of managing their medication with it.
Inflammatory Bowel Disease (IBD) er en langvarig sygdom i fordøjelsessystemet. At følge den ordinerede behandling kan forebygge opblussen og forbedre helbredet. Mobile sundhedsapps (mHealth) kan støtte overholdelse af behandling med funktioner som påmindelser og medicinregistrering. Dette projekt designede og evaluerede en mHealth-app, der skal støtte medicinoverholdelse hos personer med IBD. Appen blev bygget i React Native, et rammeværk til at udvikle mobilapps. Vi evaluerede den gennem opgavebaserede brugervenlighedstests, standardiserede spørgeskemaer—mHealth App Usability Questionnaire (MAUQ) og Perceived Competence Scale (PCS)—samt semistrukturerede interviews. Femten deltagere gennemførte ni opgaver for at vurdere appens brugervenlighed og funktionalitet. På syvpunktsskalaer var gennemsnitsscorerne 5,54 på MAUQ og 5,62 på PCS, hvilket peger på høj oplevet brugervenlighed og kompetence. Der var desuden en stærk positiv sammenhæng mellem oplevet brugervenlighed og oplevet kompetence: Deltagere, der vurderede appen som lettere at bruge, følte sig også mere i stand til at håndtere deres medicin med den.
