[The AEIOU Model: Effective Health Behaviour Change in Practice Based on Behavioural Insights]
1Institut für Medizinische Soziologie und Rehabilitationswissenschaft, Charité Universitätsmedizin Berlin, Berlin, Deutschland.
Background:
The use of Behavioural Insights (BI) is gaining increasing attention in the German health landscape. Abstract English-language models provide assistance in the application of BI. However, so far there is no model which (1) is specifically suitable for the health sector and (2) is based on the German language. In this context, the goal was to develop a comprehensive German-language BI model for the design of interventions that can change health behaviour.
Methods:
The basis for the development were the two models MINDSPACE and EAST as well as the authors' own practical experiences.
Results:
The developed AEIOU model consisted of five categories with a total of 20 instruments, the categories being (1) address (Ansprache), (2) simplicity (Einfachheit), (3) incentivisation (Incentivierung), (4) orientation (Orientierung), and (5) immediacy (Unmittelbarkeit).
Conclusion:
The AEIOU model forms the basis for the first German-language compilation of possible BI applications for the development of interventions in the health sector. The model has now to be tested in practice and examined for its usefulness.
