The digital transformation in the health sector holds great potential to meet the challenges of demographic change, the financial burden on the health system and the shortage of healthcare professionals. One digital solution is the use of modern information and communication technologies (ICT), such as eHealth (health-related websites) and mHealth applications (mobile health apps). However, the use of digital ICT in the German health care system is still in the start-up phase and the rate of use of health apps can also be characterised as low. The current state of research also shows many research gaps with regard to user acceptance and user diversity. This work therefore examines acceptance-relevant motives and factors with regard to the use of digital ICT, taking user diversity into account, and provides answers regarding the requirements for ICT as well as the influence and relevance of user factors. In addition, it provides information on the methodological procedure and the content design of acceptance studies. The theoretical model basis is the UTAUT2 acceptance model, which is transferred to the field of health care and extended by attitude and ability-related factors. The methodological research framework is the human-centred design cycle. The survey is based on a multi-step, multi-method empirical approach that focuses on users and elicits attitudes and opinions about health-related websites and health apps from their perspective. It shows that hedonic motivation (factors that evoke fun and motivation), performance expectancy (perceived usefulness of the app), social influence (social affiliation) and facilitated conditions (knowledge of how to use the app) contribute most to the intention to use ICT. Age, privacy attitude, trust in technology and the level of digital health literacy represent the most acceptance-relevant user factors. With regard to the application context, the greatest benefit is seen in the context of monitoring (reha apps), followed by fitness and care apps. Considering the design and action recommendations resulting from this work, it should be possible to come a decisive step closer to improving the health system.
