Abstract
Inflammatory bowel disease (IBD) is a long-term condition of the digestive tract. To reduce flare-ups and improve health, people need to follow their treatment plans consistently. Mobile health (mHealth) apps can support this through features such as reminders and medication tracking. This project designed and evaluated an mHealth app intended to support medication adherence for people with IBD. The app was built with React Native (a software framework for mobile apps) and evaluated through task-based usability testing, two standard questionnaires, the mHealth App Usability Questionnaire (MAUQ) and the Perceived Competence Scale (PCS), and semi-structured interviews. Fifteen participants completed nine tasks to assess how easy the app was to use and how well its features worked. Participants reported high usability and competence, with mean scores of 5.54 on the MAUQ and 5.62 on the PCS on seven-point Likert scales. There was a strong positive relationship between usability and perceived competence: participants who found the app easier to use also tended to feel more capable of managing their treatment.
Inflammatorisk tarmsygdom (IBD) er en kronisk lidelse i mave-tarm-systemet. For at mindske opblussen og forbedre helbredet er det vigtigt at følge sin behandling over tid. Mobil sundhed (mHealth) apps kan støtte dette med funktioner som påmindelser og registrering af medicin. Dette projekt designede og evaluerede en mHealth-app, der skal hjælpe personer med IBD med at følge deres medicinplan. Appen blev udviklet i React Native (et softwareframework til mobilapps) og vurderet med opgavebaserede brugervenlighedstests, to standardspørgeskemaer, mHealth App Usability Questionnaire (MAUQ) og Perceived Competence Scale (PCS), samt semistrukturerede interviews. Femten deltagere gennemførte ni opgaver for at vurdere, hvor let appen var at bruge, og hvordan funktionerne fungerede. Resultaterne viste høj oplevet brugervenlighed og kompetence, med gennemsnitsscorer på 5,54 for MAUQ og 5,62 for PCS på syvpunktsskalaer (Likert-skalaer). Der blev fundet en stærk positiv sammenhæng mellem brugervenlighed og oplevet kompetence: Jo lettere appen blev oplevet, desto mere kompetente følte deltagerne sig i at håndtere deres behandling.
