Background and study aims
To investigate snacking behaviour and how to affect it in relation to mood and physiology, the study team developed the SnackBox. The SnackBox accurately tracks snacking behaviour without actions of the researcher or user and then uses this information to trigger ecological momentary assessments to assess perceived mental well-being or just-in-time-adaptive interventions (JITAIs) to support healthy snacking behaviour. This study will investigate the effect of JITAIs on snacking behaviour. The primary objective of this study is to validate the effect of JITAIs (Just-In-Time-Adaptive Interventions) on snacking behaviour, assessed with the SnackBox. As secondary objectives, the study investigates the effect of the JITAIs on participants’ mood, and if and which factors (demographics, eating behaviour scores, mental well-being scores and physiology) affect JITAI outcomes.

Who can participate?
Adults aged between 18 and 49 years old who have at least eight days in which he/she works from a location with a stationary place to take breaks (f.e. desk or canteen) within a maximum period of 14 days.

What does the study involve?
Participation will consist of a pre-screening questionnaire, an intake session, 10 measurement days (divided over 14 days) and a hand-over session. Participants are asked to set up the Snackbox at their desk at home or at the office/break room for 10 days spread over 14 days at maximum. In the evenings you are asked to bring the SnackBox to your living room or other location you spend your evening. You will also wear the Garmin only on those 10 days.

What are the possible benefits and risks of participating?
In this study, no discomforts or side effects are expected. If you do experience such issues, immediately contact the principal investigator. It is important that you properly consider the possible advantages and disadvantages before you decide to participate. You will not personally receive any advantage from taking part in this study. Your participation may contribute to more knowledge about SnackBox. Disadvantages are possible discomforts of the measurements in the study, the main burden for the participant is expected to be the refrainment from other snacks on measurement days and the numerous questionnaires that need to be filled out.

Study acronymAphrodite II
Study objectivesThe primary objective of this study is to validate the effect of a just-in-time-adaptive intervention (JITAI) on snacking behaviour in daily life, assessed with the SnackBox.
Ethics approval(s)Ethics approval not required
Ethics approval additional informationThe study has no medical grounds and does not fall under the medical scientific research act. We have sought an opinion on ethics approval both internally, with colleague Fabian Beutel from the internal medical ethical committee (INMEC) of Imec, and externally with the ‘Medische Ethische Toetsings Commissie” (METC) Veldhoven.
Health condition(s) or problem(s) studiedOverweight and obesity
InterventionParticipants are asked to install a SnackBox at the place where they usually snack (home and/or work) and to use it on their work days for a two-week period. On each of these measurement days, the participants are asked to take all in-between-meal food and drinks from the SnackBox, to refrain from snacks not included in the study and to wear the Garmin Vivosmart 5 the entire day. Additionally, the participants receive several questionnaires throughout each of these days to assess their meals, their mood states and some contextual information. The second week is the feedback week, where participants in the intervention group, in addition to the aforementioned questionnaires, receive the just-in-time-adaptive intervention (JITAI) on their smartphones.

SnackBox:
The SnackBox, a device developed within OnePlanet, will be used to record the snacking behaviour of the child during the measurement period. The device contains three weighing stations where different types of snacks can be weighted. Snacks will be weighted in special designed boxes. These compartments can be closed with an airtight lid. The SnackBox is placed on the participant’s home and must be connected to a power socket for power supply. Each of the three weighing stations exists of a load cell that measures the weight of its content. A Raspberry Pi (RBPi) computer, placed inside the station, collects and stores the weight data as well as data from the accelerometer located on the bottom of the weight station. The SnackBox also identifies when a snack compartment is not placed back on its weighing station and provides feedback to the user by using a blinking LED light and a buzzer sound. Lastly, the SnackBox registers which snack is placed on each of the weighing stations by registering its NFC tag. All snack compartments are labelled with NFC tags by the researchers prior to the measurements.

Randomisation:
For men and women separately, intervention is randomly assigned by drawing either ‘Intervention’ or ‘Control’ cards from a pool.
Intervention typeBehavioural
Primary outcome measureGrams consumed from “healthy” and “unhealthy” snacks measured using the SnackBox at week 1 and week 2
Secondary outcome measuresThe effect of the JITAI messages on mood measured using the difference in mood Visual Analogue Scores (VAS) at random times of the day between the intervention week with JITAI messages and the baseline week without JITAI messages (corrected for that same difference in the control group)
