Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main question it aims to answer is:
• what is the right time and the right location to send notifications to people and for what type of interventions are people most receptive? Furthermore, the aim is to get insight into the relevance and usability of the app, the privacy concerns that people have and the perceived effectiveness of the app on dietary intake.
Participants will test our app for 2 weeks, of which they will receive prompts during one week.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In this feasibility study a newly developed app is tested with the aim to get insight into what factors influence the receptiveness of people. Receptiveness is the person's ability to receive, process, and use the support provided, which is a prerequisite to achieve behaviour change. In the pilot study the aim is to investigate when and where the right time is to send notifications to people and for what type of interventions people are most receptive.
Participants are inhabitants of Wageningen who will test our app for 2 weeks. In the first week nothing is expected from the participants, but their movement patterns are collected via GPS; the participants are their own control for the Just-In-Time principle. In the second week the participants receive notifications (i.e., a healthy recipe, a tip for the healthier option at a certain location) based on their selected goal (eating more vegetables, eating less meat, less unhealthy snacking). After receiving the notification, participants are asked to answer several questions. At the end of the day, participants are asked to give us more insight in what they like and dislike to receive, at which locations, at what times, how many times a day, and their reasons behind this.
With this data the app can be further developed (co-creation).
The results of the study will be analysed within persons to visualize patterns. A second goal is to test if the movement patterns of participants can be used to objectively measure if interventions are effective in the future. The movement patterns will be analysed with the use of different algorithms, to see if and how movement patterns can say anything about the behaviour of people (stopping, standing still, alter routes). The movement patterns can be linked to received interventions, locations and receptivity.
Within this pilot study, people are not asked to alter their behaviour. Participants do receive notifications that are focused on making healthier eating choices, but the expectation is that this will not lead to behavioural changes within one week. The goal of the study is to get better insight into the best way to respond to the Just-In-Time principle. Participants will receive zero to several notifications a day for a period of 1 week.

Study Groups

Test group of app
All participants will first use the app one week without receiving just-in-time notifications. Their movement patterns are collected through GPS. In the second week, they will receive just-in-time notifications based on their chosen goal. Participants will act as their own control group.
Just-In-Time Adaptive Intervention
Participants will be exposed to a new innovative app to test.
