Improving the Sense of Progress in A Weight-Loss Application for Families With Obese Children

Achkoudir, Rami January 2022 (has links)
The societal problem of pediatric obesity is growing in Sweden with more patients receiving pediatric treatment while the treatment measures have not improved to match the increase. This exploratory study examines a mobile application aiming to improve treatment for pediatric obesity. The study will evaluate the current application through the lens of HCI with a focus on self-care and will be based on digital behavior change intervention (DBCI), persuasive systems, and playful user-centered design (UCD), with design recommendations stated based on the evaluation. User-centered design is a design process involving end-users in the design process, the users were involved through semi-structured interviews. User-centered design is a large part of the study with user input laying the foundation for new design recommendations. Users thought that the application would benefit from having more short-term goals to boost motivation. Furthermore, a heuristic analysis was done to get an expert view on the user interface. The results were promising and indicated some potential improvements for the application, one suggested improvement was to provide more positive feedback to boost motivation. The thesis discusses how more visualization of data might have the potential to both boost motivation and result in a more playful user experience. / Samhällsproblemet med barnfetma växer i Sverige med fler patienter som får pediatrisk behandling samtidigt som behandlings åtgärderna inte har förbättrats för att matcha ökningen. Denna explorativa studie undersöker en mobilapplikation som syftar till att förbättra behandlingen av barnfetma. Studien utvärderar den aktuella applikationen och är baserad på digital beteendeförändringsintervention (DBCI), persuasive systems och lekfull användarcentrerad design (UCD), med designrekommendationer angivna baserat på utvärdering samt semistrukturerade intervjuer. Användarcentrerad design är en stor del av studien med användarinput som lägger grunden för nya design rekommendationer. Intervjuerna lyfte fram att applikationen skulle tjäna på att ha fler kortsiktiga mål för att öka motivationen. Resultaten indikerade potentiella förbättringar för applikationen, exempelvis att ge mer positiv feedback. Slutligen diskuteras hur en mer genomarbetad visualisering av data kan leda dels till ökad motivation och dels till mer lekfull interaktion.
