Design för långvarig hälsoförbättring : Hur designfaktorer i hälsoapplikationer kan användas för att motivera användare till en långvarig förändring.

Sammanfattning: An unhealthy diet and insufficient physical activity lead to global health risks, where 70% of all deaths globally can be linked to non-communicable diseases. To change these types of behaviours, there are different methods, one of which is the Behaviour Change Wheel (BCW) which can serve as a guide to which methods can be used to achieve a behaviour change. The purpose of this study is to investigate how health applications can motivate users to a long-term health improvement. What are the important design factors in health applications for users, to be motivated to a long-term health improvement?   To fulfil the purpose, a study was conducted with a qualitative approach inspired by Design Science. For data collection, semi-structured interviews were conducted and data generated were analysed using thematic analysis.   The study showed that a number of the recommended Behavioural Change Techniques (BCTs) that could be found in BCW are consistent with respondents' personal experiences and opinions on desirable functions for achieving a healthier lifestyle. The results of this study indicate that important design factors in a health application are easily used functions that allow a user to find reliable information when needed, track their goals and evaluate these in relation to their previous achievements to continue to be motivated for  a long-term change.
