Users' needs for a digital smoking cessation application and how to address them: Data and analysis code



This is the data and analysis code underlying the paper "Users' needs for a digital smoking cessation application and how to address them: A mixed-methods study" by Nele Albers, Mark A. Neerincx, Kristell M. Penfornis, and Willem-Paul Brinkman. The goal of this paper is to get a more accurate assessment of users' needs for eHealth applications for behavior change, with the focus on smoking cessation.

The paper is based on a study in which smokers who were contemplating or preparing to quit smoking interacted with the text-based virtual coach Sam in up to five conversational sessions. In each session, participants were assigned a new preparatory activity for quitting smoking, such as thinking of and writing down reasons for quitting smoking. Since becoming more physically active may make it easier to quit smoking, half of the activities addressed becoming more physically active. In the next session, participants were asked to provide feedback on their activity by means of a rating of the effort they spent on the activity and a free-text response describing their experience with the activity. After the five sessions, participants filled in a post-questionnaire in which they were asked about their feedback on their activity from the last session, barriers and motivators for doing their activities, and views on videos of interaction scenarios. These videos showed interaction scenarios such as receiving motivational messages from the virtual coach, telling one's social environment about one's quit attempt, or consulting a general practitioner in case of a smoking relapse. There were 13 different videos, and each participant saw 2 of them.

We collected four main types of data from participants:1) the effort people spent on their activity from the last session and their experience with it, 2) barriers and motivators for doing the activities, 3) views on interaction scenarios, and 4) user characteristics (e.g., age, smoking frequency, physical activity identity).
