Abstract:Background: Online interventions which aim to make all kinds of therapy more accessible , such as Alcohol de baas, have the advantage that they reach populations that are difficult to approach. However the drop-out rate found for this kind of interventions is still too high. Research at the University of Twente tries to address the problem of high drop-out rates by integrating the E4 biosensor into the Alcohol de baas program to be able to provide individual feedback. As part of the research done in Twente, this work investigates the user-acceptance of the E4. This acceptance is important regarding the persistent usage of the sensor during the intervention. Goal: The goal of this work is to investigate the user-acceptance of the E4. This is investigated regarding the aspects of wearing comfort, perceived anonymity and the awareness of drinking behavior. Method: For the period of one week, eight subjects have worn the E4 in their daily lives. After that they were asked to participate in an semi-structured interview in which they were asked question about the aforementioned aspects. Results: Reading the wearing comfort, the subjects reported that they could get easily used to the sensor for the period of one week. However they also reported some negative aspects like the sensor not being waterproof and physical discomfort while wearing the device. No negative influence on the perceived anonymity has been reported by the subjects. Finally, wearing the sensor did have influence on the awareness of drinking behavior of the subjects, but not on the drinking behavior itself. Conclusion: The acceptance of the sensor was not negatively influenced for the investigated period of time and with the participating subjects. However, further research is recommended, since some negative aspect have been reported. It is not clear whether those aspects could have influence on the acceptance, in particular when regarding the intended group of users and a longer period of usage of the E4.
