Plain English Summary
Background and study aims
Young people are particularly susceptible to digital technology overuse, including in response to the COVID pandemic, and are therefore vulnerable for its potential harmful effects on mental health. Problematic usage of the internet (PUI) is thought to disrupt a person’s life, with major consequences for that person, and wider consequences for societal health and well-being.
The BootStRaP study brings together a group of researchers from 12 countries, and by working together they are aiming to change the way that people and governments understand problematic internet use, and by engaging into this study to reduce the harm that digital devices like phones have on the mental health of young people.
Who can participate?
Students from schools involved in the study, aged between 12 and 16 years with routine access to a mobile phone.
What does the study involve?
Participants in the will be asked to download 2 apps to their phone. They will be asked to answer some questions on internet use, mental and physical health, how they think and behaviours over a 6 month period. These questions are broken up into blocks that will take aproximatly 1 hour to complete at the beginning of the study, at 3 months and again at 6 months. Participants will also be asked to play some online games (via the Dragon Game App) when they first start the study and again in 6 months. The games look at how quickly they respond to tasks and take about 12 minutes.
At the beginning of the study and at the end participants will be asked to complete a 7 day diary about their daily internet use, once a month participants will be asked about their internet use in a short 5 minute survey and every 8 days participants will be asked to answer 2 questions about their mood and patience that day.
As you may know, certain information is already collected by phones each day, this is known as Mobile Sensing. The study will collect some of this information while the participant is in the study, but will not be able to see the content of what they are doing on their apps, in their messages or on their calls. The following information will be collected:
How often and how much time they spend on their phone and what type of phone it is
How many and how much time they spend on which apps and the internet (web browser)
How many, when and how long they spend on phone calls and sending text messages
How many contacts they have and the number of contacts they actively engage with
Number of steps per day, distance covered and physical activity (accelerometer and rotation rate information)
What are the possible benefits and risks of participating?
On completion of the study participants will receive a certificate and shopping e-voucher to download via the BootstrApp.
Participants will also be able to get feedback both on an individual level and compared to other participants about their screen time, app use, game scores and some questionnaire results.
Participation in the study will be helping improve mental health and well-being for young people across Europe and beyond.
Although we do not believe that the questions asked will upset participants, we understand it is difficult for some people to discuss personal things such as mental health.
If a participant becomes distressed during the study, the BootstrApp will have information about where they can find help if they think they need it, from both national organisations and at local levels and from the participant school.
Where is the study run from?
The study will be conducted online via the BootstrApp across 9 European countries (United Kingdom, France, Germany, Hungary, Lithuania, Netherlands, Portugal, Spain and Switzerland).
The study is led by researchers at the University of Hertfordshire in the UK with researchers from 11 other countries.
When is the study starting and how long is it expected to run for?
This study is the 1st phase of a larger project which started on the 1st July 2023 and will run for 5 years. Phase one of the study will run for 1 year and finish in July 2025, this will be followed by an intervention study (running from 2025 - 2026) and a randomised clinical trial (RCT) (running from 2026 - 2027). The result from each phase will be utilised by the next phase of the project.
Who is funding the study?
The study is funded by European Union, European Health and Digital Executive Agency (HADEA), The Research and Innovation Fund, Innovate UK program (UKRI) and The Swiss Confederation, State Secretariat for Education Research and Innovation (SERI)

Scientific title | Boosting Societal Adaptation and Mental Health in a Rapidly Digitalizing, Post-Pandemic Europe |
Study acronym | BootStRaP |
Study hypothesis | Extensive use of the internet has given rise to problematic patterns of use, involving loss of control of time spent online, that have adverse effects on the health and well-being of individuals, especially teenagers. Problematic use of the Internet (PUI) is an umbrella term describing a broad range of potentially harmful forms of online behaviour, such as excessive gambling, gaming, social media use. The EU-funded Bootstrap project aims to mitigate the risks. It will carry out research across Europe to closely monitor the internet usage patterns of young people, to identify patterns of PUI behaviours that result in harm, and devise strategies to tackle these issues. Primary Objectives 1. Determine the multifactorial determinants of healthy vs. unhealthy internet usage among European adolescents aged 12-16 years and develop algorithms for quantifying individual risk of PUI. The algorithms will be developed applying both classical and modern machine learning techniques. The primary endpoint quantifying PUI is the short compulsive internet use scale (S-CIUS) (Besser et al., 2017; Pérez-Sáenz et al., 2023). In addition, PUI symptoms will be quantified by the PIUQ (Demetrovics et al., 2008), the ISAAQ (Omrawo et al., 2023) and the ACSID-5 (Müller et al., 2022). (at baseline and t2) 2. Use these algorithms to develop a new, user friendly, digital platform supported on a smartphone app (BootstrApp) that would enable early detection of adolescents ‘at risk’ of PUI before it is apparent, as a prototype method for early targeted intervention 3. Determine the health economic impact of PUI for European adolescents. Health economic impact will be reported as cost and burden of PUI in European adolescents |

Condition | Problematic usage of the internet in adolescents |
Intervention | For a period of 6 months, participating students will be prospectively assessed by having a specifically developed mobile app – the BootstrApp - installed on their smartphone, which will prompt the students to complete questionnaire assessments regarding their mood, cognitive abilities, and Internet usage. There will be three survey-based main assessments (T1-T2, 1h per assessment, spaced by 3 Months). Short additional questionnaires will be integrated at defined timepoints throughout the study. This includes four additional assessments of the (S-CIUS) (Besser et al., 2017; Pérez-Sáenz et al., 2023), to provide monthly information on PUI, two 7-day periods (after T1 and T2) of daily information on activities on the internet and affect, and two items on mood and patience that will be queried every eight days. Further passive mobile sensing data will be collected by the smartphone app itself (e.g. actual time and frequency using the smartphone per day). |
