other nine problems were less likely to influence future usage of the tool substantially.
Conclusions
The usability of the DTTSQ needs to be improved before it can be released. No problems were found with satisfaction or efficiency during the usability-test. The effectiveness needs to be improved by 1. making it easier to navigate through screens without the possibility of accidently skipping one, 2. enable the possibility to insert an answer by tapping on the text underneath a photograph instead of just touching the photograph itself and 3. making it easier to correct wrong answers. This study shows the importance of including less skilled participants in a usability study when striving for inclusive design and the importance of measuring not just satisfaction but also efficiency and effectiveness during such studies. Further research is necessary to gain more insight into the needs, preferences, capacities, values, and goals in relation to mHealth technology of people with little or no experience with using mobile technology.
INTRODUCTION
EHealth is developing rapidly [1]. It is defined as the use of information and communication technology (ICT) in healthcare [2]. A growing amount of literature indicates that using eHealth can improve the accessibility, quality and efficiency of health care [3,4,5]. It seems to be effective for people who have access to it and are able to use it well, which is not the case for everybody [6,7]. For instance, people with low income or low education and people who are 65 years and older are vulnerable when it comes to effective eHealth use. In these populations access to the internet and hardware like personal computers, tablets, mobile phones and smartphones and experience and skills to use these devices is low [6,7,8,9]. Differences between people regarding digital skills and access to internet and hardware is often referred to as the digital divide [10,11]. Since eHealth technologies are usually primarily developed for people who are experienced and skilled in using ICT [12,13], people who do not have access to ICT or are not skilled in using it, are at risk of being excluded from the use of eHealth. Looking at the widespread expansion of eHealth technologies this encompasses the potential threat of contributing to the ongoing exacerbation of health inequalities in western countries [1]. However, if the needs,
